The Mechanics Of Steroids

A $252 million contract to play baseball causes "an enormous amount of pressure ... to perform at a high level every day," according to Alex Rodriguez. The New York Yankees' third baseman provided a few more details last week about the anabolic steroids he used from 2001 to 2003 after he had signed a record-setting deal with his former team, the Texas Rangers.

Here is what most of us know about anabolic steroids: they make muscles grow faster, there are harmful side effects to our health, most sports leagues have banned them, and they are illegal without a prescription.

But how do they actually work? Does an athlete just pop a few pills and then wait for the Popeye-spinach effect? Let's dig a little deeper into the science of steroids.

Legal uses
Anabolic steroids, or anabolic-androgenic steroids (AAS), are the synthetic (made in a lab) derivatives of the naturally produced hormone testosterone. They promote the growth of muscle (anabolic effect) and the typical male characteristics of puberty (androgenic effect).

When legally prescribed, they are an option for patients who produce abnormally low levels of testosterone or who suffer from body-wasting diseases such as cancer or AIDS. When used by athletes, the goal is to speed up the body's natural muscle-building process.

When we lift weights heavier than what we're used to, we create tiny micro-tears in muscle fibers. The body's natural repair process repairs the tear and then overcompensates by adding bigger cells to build a stronger fiber — this is called muscular hypertrophy. Over time, this repeated process of teardown and re-build will result in muscle growth.

Natural testosterone is the body's main ingredient for this process, but anabolic steroids can serve as a supplement.

Once ingested, an AAS travels through the blood stream to the muscle tissue. It is drawn into the muscle cell's receiving dock, called an androgen receptor. Once delivered to the muscle cell, the steroid can interact with the cell's DNA and stimulate the protein synthesis process that promotes cell growth.

Different variants and amounts of AAS can cause different reactions producing either massive body-building physiques or more toned athletic muscles (i.e. Barry Bonds vs. A-Rod). Athletes experiment with different combinations (called stacking) or regimens (pyramiding) in an attempt to fine-tune the final result.  A-Rod's stack was reportedly straight testosterone and Primobolan.

Beyond bulk
While the focus in the media is on the bulked-up home run hitters, anabolic steroids can also benefit pitchers and others who need a faster turnaround from sore, overused muscles. Intense exercise also releases cortisol, known as the stress hormone, which breaks down muscle tissue, producing sore muscles.

AAS can block cortisol from binding to the muscle cell's receptor sites, which diminishes the breakdown process. Less muscle breakdown means less muscle fatigue which would allow a pitcher to recover more quickly from a nine-inning outing.

Besides all of the known negative side effects of using steroids just for ergogenic reasons, there is also the uncertainty of what exactly you are taking. Last month, federal Drug Enforcement Administration agents arrested the owners of an Alabama-based online pharmacy on charges that they filled hundreds of illegal prescriptions for anabolic steroids for clients across the country.

The worst news for the customers of this pharmacy was delivered by U.S. Attorney Deborah Rhodes: "Each of the pharmacy owners and pharmacists named in the indictment are charged with prescribing and selling veterinary steroids, approved for cattle and livestock only, to humans."

How Should Cheating Be Defined In Sports?

When Milwaukee Brewers pitcher Chris Capuano reports for spring training in April, he will be anxious to demonstrate the effects of a performance-enhancing off-season. His brain will benefit from a sharper focus while his throwing arm will boast an extra boost that has been missing since 2006. Stimulants? Steroids? Scandal? No need to panic, he just had LASIK surgery for his eyes and "Tommy John" surgery for his injured elbow. Of course, had he chosen amphetamines to improve his focus or steroids to increase his strength, he would have been banned and berated. 

Society Decides

There is confusion over the means and methods athletes have available to enhance their performance. Certainly, corrective eye surgery to raise your vision level to 20/20 seems fair, but many athletes go into the procedure hoping to come out with enhanced 20/15 or 20/10 eyesight. Replacing a damaged elbow ligament with a tendon doesn't seem like cheating, but what if its done on a healthy elbow hoping for a few more miles per hour on a fastball that has faded over the years?

Earlier this month, a commentary in the journal Nature recommended a fresh look at cognitive-enhancing drugs and where to draw the line in the sand between natural performance and enhanced performance. The authors, an esteemed group of neuroscientists and ethicists, argued that "enhanced" is only defined by the rules set by society.

Certainly, abuse of prescription drugs, such as Ritalin and Adderall, is illegal because of the potential, harmful side effects. Still, reports of the rising use of these drugs by college students and professionals show the demand for options beyond nutrition, exercise and sleep.

These drugs are just the first generation of possible brain boosting supplements, which is why the Nature commentators are calling for an organized, stigma-free approach to evaluating the risks, benefits and ethics of future products.

Even in Major League Baseball, there is mounting evidence that cognitive-enhancing drugs may be on the rise. Since MLB banned amphetamines in 2006, there has been a dramatic rise in the number of therapeutic use exemptions issued to players for attention-deficit disorder diagnoses, for which drugs like Ritalin and Adderall can be legitimately prescribed. In 2006, 28 players applied for the exemption, while a year later there were 103. There is suspicion that many of these ADD diagnoses are just excuses to get the pills.

Legal Jolt

So, what if there was a cognitive-enhancing, sports supplement that increased alertness, concentration, reaction time and focus while also decreasing the perception of muscle fatigue? Even more encouraging, this supplement is sold in millions of outlets and is socially accepted worldwide. It comes in three sizes, tall, grande or venti – coffee. More specifically, caffeine has been the subject of many recent studies of its effectiveness, both cognitively and physiologically.

Earlier this year, Dr. Carrie Ruxton completed a literature survey to summarize 41 double-blind, placebo-controlled trials published over the past 15 years to establish what range of caffeine consumption would maximize benefits and minimize risk for cognitive function, mood, physical performance and hydration. The studies were divided into two categories, those that looked at the cognitive effects and those that looked at physical performance effects.

The results concluded that there was a significant improvement in cognitive functions like attention, reaction time and mental processing as well as physical benefits described as increased "time to exhaustion" and decreased "perception of fatigue" in cycling and running tests.

Given these results, how exactly does caffeine perform these wonderful tricks? Dr. Ruxton explains from the study, "Caffeine is believed to impact on mood and performance by inhibiting the binding of both adenosine and benzodiazepine receptor ligands to brain membranes. As these neurotransmitters are known to slow down brain activity, a blockade of their receptors lessens this effect."

Bottom line, the chemicals in your brain that would cause you to feel tired are blocked, giving you a feeling of ongoing alertness. This pharmacological process is very similar to that of the ADD drugs.

If caffeine is such a clear cut performance enhancing supplement, why did the World Anti-Doping Agency (WADA) first add caffeine to its banned substance list, only to remove it in 2004? At the time that it was placed on the banned list, the threshold for a positive caffeine test was set to a post-exercise urinary caffeine concentration of about 3-4 cups of strong coffee.

However, more recent research has shown that caffeine has ergogenic effects at levels as low as the equivalent of 1-2 cups of coffee. So, it was hard for WADA to know where to draw the line between athletes just having a few morning cups of coffee/tea and those that were intentionally consuming caffeine to increase their performance level.

So, if Chris Capuano has a double espresso before pitching, his brain, eyes and arm should enhance his performance in the game.  Is that an unfair advantage? Science will continue to offer new and improved methods for raising an athlete's game above the competition. Players, league officials and fans will have to decide where to draw the line.

Getting The Call Right With Technology

The loneliest men in sports have not been making any friends lately. 

Both umpires and referees have been making news, despite their often repeated goal, stated by World Series rookie umpire Tom Hallion said last month after Game 3: “As an umpire, you never want to be involved in the outcome of the game.” He added: “We like to get every play right. We’re human beings, and sometimes we get them wrong.” 

Hallion and his five partners at October's Fall Classic did not quite reach their goal. In Game 3, Hallion called Carl Crawford safe at first on a close play, but replays showed he was out. In Game 4, it was the Phillies who benefited after veteran umpire, Tim Welke, called Jimmy Rollins safe at third during a rundown, despite an obvious tag on his backside.


The men in stripes are not doing any better. Veteran NFL referee, Ed Hoculi (aka "Guns"), blew a call in Week 2's Broncos/Chargers game.  Broncos' quarterback Jay Cutler let the ball slip out of his hand and the Chargers recovered.  However, Hoculi ruled the play an incomplete pass. The video replay booth called it a fumble, but since Hoculi had blown his whistle, the call could not be reversed. 

Not to be outdone by their American counterparts, two English soccer officials have set a new standard for head-scratching calls.

In a Sept. 22 game between Watford and Reading, referee Stuart Atwell and one of his linesmen, Nigel Bannister, combined to become the ultimate sales pitch for any type of goal-line replay technology. After a scramble in front of goal, the ball bounced across the end line, two yards wide of the nearest goalpost. As both teams headed up the field and Watford prepared for a goal kick, Bannister signaled to Atwell that he saw the ball cross the line between the goalposts and that Reading should be awarded a goal. To the astonishment of all 22 players on the field and the 14,761 fans, Atwell overruled his own eyes and gave the goal to Reading. The replay made it painfully obvious how wrong the call was: 

So, assuming officials want some kind of automated technical assistance, what is available?

First, pure video instant replay gives officials a second, slower chance to see the play again and possibly adjust their live call. All four major sports leagues in the United States use replay at some level. 

In addition to judging if a shot was taken before the buzzer, the NBA added replay this season to differentiate 2-point versus 3-point baskets. MLB commissioner Bud Selig has put a stop to the spread of replay beyond the home run/foul ball call for now, but public pressure may change that. The NHL’s use of replay focuses mainly on different goal scoring scenarios. The NFL is the most advanced user of replay to judge multiple situations.

Second, an emerging selection of decision-support tools can make the actual call for the officials using location-based technology. In tennis, the Hawk-Eye system is being used at such high-profile events as Wimbledon and the U.S. Open. 

A system of six high-speed cameras records a ball's movement, which is useful when it bounces near one of the court lines. It feeds the cameras' input to a central computer that analyzes the data from all angles and then creates a motion graphic that simulates the ball's location when it bounces on the court, either on the line or next to the line, with a judgment of "in" or "out."

A player can challenge a line umpire's original call, but Hawk-Eye's ruling is then final. The interesting illusion that tennis fans have accepted is watching this 3D simulation as if it is based on a single camera’s footage of the ball. Actually, the sequence shown to viewers is Hawk-Eye's best estimate as to what actually happened based on the data it received from the cameras. There have been more than 550 challenges at the U.S. Open since 2006 when Hawk-Eye was installed. Thirty percent of those challenges resulted in a call being reversed.

In soccer, Adidas and Cairos Technologies have partnered to create an "intelligent" ball that includes a microchip that transmits its location on the field to a computer. 

The system also places a thin, underground electrical wire that surrounds each goal. If the ball's location is sensed to be completely inside the boundary of the goal, a signal is sent to a watch worn by the referee indicating that a goal has been scored. 

This technology would have saved Atwell and Bannister from their embarrassment. However, after extensive testing at several FIFA tournaments, Sepp Blatter, president of FIFA, announced in March that instead of technology, two additional human referee assistants would be used to judge whether a goal was scored. "Let it be as it is and let's leave it (soccer) with errors," Blatter said. "The television companies will have the right to say he (the referee) was right or wrong, but still the referee makes the decision — a man, not a machine." Interestingly, the English Premier League was also testing the use of Hawk-Eye as an alternative to Adidas' smart ball.

Even if the umps and refs don't want to use the technology, sports television producers still want to empower the fans.

In baseball, ESPN's "K-zone" and Fox Sports' "Fox Trax" show a virtual representation of pitches and the strike zone to let us judge the accuracy of the home-plate umpire's calls. Think that last called strike was a bit outside?  Watch the computer generated replay that is accurate to within one-half inch. 

Then, go ahead and yell at the ump. If only they could come up with a way to transmit our voices directly into the stadium.

Baseball Brains - Fielding Into The World Series

With the crack of the bat, the ball sails deep into the outfield. The center-fielder starts his run back and to the right, trying to keep his eyes on the ball through its flight path. His pace quickens initially, then slows down as the ball approaches. He arrives just in time to make the catch. What just happened? How did he know where to run and at what speed so that he and the ball intersected at the same exact spot on the field. Why didn't he sprint to the landing spot and then wait for the ball to drop, instead of his controlled speed to arrive just when the ball did? What visual cues did he use to track the ball's flight?  Did Willie Mays make the most famous catch in baseball history because he is one of the greatest players of all-time with years of practice? Maybe, but now take a look at this "Web Gems" highlight video of 12 and 13 year-olds from last year's Little League World Series:

Just like we learned in pitching and hitting, fielding requires extensive mental abilities involving eyes, brain, and body movements to accomplish the task. Some physical skills, such as speed, do play a part in catching, but its the calculations and estimating that our brain has to compute that we often take for granted. The fact that fielders are not perfect in this skill, (there are dropped fly balls, or bad judgments of ball flight), begs the question of how to improve? As we saw with pitching and hitting (and most sports skills), practice does improve performance. But, if we understand what our brains are trying to accomplish, we can hopefully design more productive training routines to use in practice.

Once more, we turn to Mike Stadler, associate professor of psychology at University of Missouri, who provides a great overview of current fielding research in his book, "The Psychology of Baseball".

One organization that does not take this skill for granted is NASA. The interception of a ballistic object in mid-flight can describe a left fielder's job or an anti-missile defense system or how a pilot maneuvers a spacecraft through a three dimensional space. In fact, Michael McBeath , a former post doctoral fellow at the NASA Ames Research Center, (now an associate professor at Arizona State University), has been studying fly ball catching since 1995, beginning with his research study, "How baseball outfielders determine where to run to catch fly ball". 

His team developed a rocket-science like theory named Linear Optical Trajectory to describe the process that a fielder uses to follow the path of a batted ball. LOT says the fielder will adjust his movement towards the ball so that its trajectory follows a straight line through his field of vision. Rather than compute the landing point of the ball, racing to that spot and waiting, the fielder uses the information provided by the path of the ball to constantly adjust his path so that they intersect at the right time and place.

The LOT theory is an evolution from an earlier theory called Optical Acceleration Cancellation (OAC) that had the same idea but only explained the fielder's tracking behavior in the vertical dimension. In other words, as the ball leaves the bat the fielder watches the ball rise in his field of vision. If he were to stand still and the ball was hit hard enough to land behind him, his eyes would track the ball up and over his head, or at a 90 degree angle. If the ball landed in front of him, he would see the ball rise and fall but his viewing angle may not rise above 45 degrees. LOT and OAC argue that the fielder repositions himself throughout the flight of the ball to keep this viewing angle between 0 and 90 degrees. If its rising too fast, he needs to turn and run backwards. If the viewing angle is low, then the fielder needs to move forward so that the ball doesn't land in front of him. He can't always make to the landing spot in time, but keeping the ball at about a 45 degree angle by moving will help ensure that he gets there in time. While OAC explained balls hit directly at a fielder, LOT helps add the side-to-side dimension, as in our example of above of a ball hit to the right of the fielder.  More recently, McBeath has successfully defended his LOT theory here and here.

The OAC and LOT theories do agree on a fundamental cognitive science debate. There are two theories of how we perceive the world and then react to it. First, the Information Processing (IP) theory likens our brain to a computer in that we have inputs, our senses that gather information about the world, a memory system that stores all of our past experiences and lessons learned, and a "CPU" or main processor that combines our input with our memory and computes the best answer for the given problem. So, IP would say that the fielder sees the fly ball and offers it to the brain as input, the brain then pulls from memory all of the hundreds or thousands of fly ball flight paths that have been experienced, and then computes the best path to the ball's landing point based on what it has "learned" through practice. McBeath's research and observations of fielders has shown that the processing time to accomplish this task would be too great for the player to react.

OAC and LOT subscribe to the alternate theory of human perception, Ecological Psychology (EP). EP eliminates the call to memory from the processing and argues that the fielder observes the flight path of the ball and can react using the angle monitoring system. This is still up for debate as the IPers would argue "learned facts" like what pitch was thrown, how a certain batter hits those pitches, how the prevailing wind will affect the ball, etc. And, with EP, how can the skill differences between a young ballplayer and an experienced major leaguer be accounted for? What is the point of practice, if the trials and errors are not stored/accessed in memory?

Of course, we haven't mentioned ground balls and their behavior, due to the lack of research out there. The reaction time for a third baseman to snare a hot one-hopper down the line is much shorter. This would also argue in favor of EP, but what other systems are involved?

Arguing about which theory explains a fielder's actions is only productive if we can apply the research to create better drills and practices for our players. The LOT theory seems to be  getting there as an explanation, but there is still debate over EP vs. IP . So many sport skills rely on some of these foundations, that this type of research will continue to be relevant.  As with pitching and hitting, fielding seems to improve with practice.

And then there's the ultimate catch of all-time, that baseball fans have long been buzzing about.  Your reward for getting to the end of this article is this little piece of history...




You were looking for Willie Mays and "The Catch", weren't you?  This ball girl would own the best all-time fielding achievement... if it were real.  But no, just another digital editing marvel.  This was going to be a commercial for Gatorade, then it was put on the shelf.  After it was leaked onto YouTube, the video hoax became a viral hit.  So much so, that Gatorade left it on YouTube and did make a commercial out of it for the 2008 All-Star game.  But, you don't need to tell your Little Leaguers.  Let them dream...

Baseball Brains - Hitting Into The World Series

Ted Williams, arguably the greatest baseball hitter of all-time, once said, "I think without question the hardest single thing to do in sport is to hit a baseball". Williams was the last major league player to hit .400 for an entire season and that was back in 1941, 67 years ago! In the 2008 Major League Baseball season that just ended, the league batting average for all players was .264, while the strikeout percentage was just under 20%. So, in ten average at-bats, a professional ballplayer, paid millions of dollars per year, gets a hit less than 3 times but fails to even put the ball in play 2 times. So, why is hitting a baseball so difficult? What visual, cognitive and motor skills do we need to make contact with an object moving at 70-100 mph?

In the second of three posts in the Baseball Brains series, we'll take a quick look at some of the theory behind this complicated skill. Once again, we turn to Professor Mike Stadler and his book "The Psychology of Baseball" for the answers.  First, here's the "Splendid Splinter" in action:

A key concept of pitching and hitting in baseball was summed up long ago by Hall of Fame pitcher Warren Spahn, when he said, “Hitting is timing. Pitching is upsetting timing.” To sync up the swing of the bat with the exact time and location of the ball's arrival is the challenge that each hitter faces. If the intersection is off by even tenths of a second, the ball will be missed. Just as pitchers need to manage their targeting, the hitter must master the same two dimensions, horizontal and vertical. The aim of the pitch will affect the horizontal dimension while the speed of the pitch will affect the vertical dimension. The hitter's job is to time the arrival of the pitch based on the estimated speed of the ball while determining where, horizontally, it will cross the plate. The shape of the bat helps the batter in the horizontal space as its length compensates for more error, right to left. However, the narrow 3-4" barrel does not cover alot of vertical ground, forcing the hitter to be more accurate judging the vertical height of a pitch than the horizontal location. So, if a pitcher can vary the speed of his pitches, the hitter will have a harder time judging the vertical distance that the ball will drop as it arrives, and swing either over the top or under the ball.

A common coach's tip to hitters is to "keep your eye on the ball" or "watch the ball hit the bat". As Stadler points out, doing both of these things is nearly impossible due to the concept known as "angular velocity". Imagine you are standing on the side of freeway with cars coming towards you. Off in the distance, you are able to watch the cars approaching your position with relative ease, as they seem to be moving at a slower speed. As the cars come closer and pass about a 45 degree angle and then zoom past your position, they seem to "speed up" and you have to turn your eyes/head quickly to watch them. While the car is going at a constant speed, its angular velocity increases making it difficult to track.

This same concept applies to the hitter. As the graphic above shows (click to enlarge), the first few feet that a baseball travels when it leaves a pitcher's hand is the most important to the hitter, as the ball can be tracked by the hitter's eyes. As the ball approaches past a 45 degree angle, it is more difficult to "keep your eye on the ball" as your eyes need to shift through many more degrees of movement. Research reported by Stadler shows that hitters cannot watch the entire flight of the ball, so they employ two tactics.

First, they might follow the path of the ball for 70-80% of its flight, but then their eyes can't keep up and they estimate or extrapolate the remaining path and make a guess as to where they need to swing to have the bat meet the ball. In this case, they don't actually "see" the bat hit the ball. Second, they might follow the initial flight of the ball, estimate its path, then shift their eyes to the anticipated point where the ball crosses the plate to, hopefully, see their bat hit the ball. This inability to see the entire flight of the ball to contact point is what gives the pitcher the opportunity to fool the batter with the speed of the pitch. If a hitter is thinking "fast ball", their brain will be biased towards completing the estimated path across the plate at a higher elevation and they will aim their swing there. If the pitcher actually throws a curve or change-up, the speed will be slower and the path of the ball will result in a lower elevation when it crosses the plate, thus fooling the hitter.

To demonstrate the effect of reaction time for the batter, FSN Sport Science compared hitting a 95 mph baseball at 60' 6" versus a 70 mph softball pitched from 43' away.  The reaction time for the hitter went from .395 seconds to .350 seconds, making it actually harder to hit.  That's not all that makes it difficult.  Take a look:

As in pitching, the eyes and brain determine much of the success for hitters. The same concepts apply to hitting any moving object in sports; tennis, hockey, soccer, etc. Over time, repeated practice may be the only way to achieve the type of reaction speed that is necessary, but even for athletes who have spent their whole lives swinging a bat, there seems to be human limitation to success. Tracking a moving object through space also applies to catching a ball, which we'll look at next time.

Baseball Brains - Pitching Into The World Series

With the MLB League Championship Series' beginning this week, Twenty-six teams are wondering what it takes to reach the "final four" of baseball which leads to the World Series. The Red Sox, Rays, Phillies and Dodgers understand its not just money and luck. Over 162 games, it usually comes down to the fundamentals of baseball: pitching, hitting and catching. That sounds simple enough. So, why can't everyone execute those skills consistently? Why do pitchers struggle with their control? Why do batters strike out? Why do fielders commit errors? It turns out Yogi Berra was right when he said, "Baseball is 90% mental, and the other half is physical." In this three part series, each skill will be broken down into its cognitive sub-tasks and you may be surprised at the complexity that such a simple game requires of our brains.

First up, pitching or even throwing a baseball seems effortless until the pressure is on and the aim goes awry. Pitching a 3" diameter baseball 60 feet, 6 inches over a target that is 8 inches wide requires an accuracy of 1/2 to 1 degree. Throwing it fast, with the pressure of a game situation makes this task one of the hardest in sports. In addition, a fielder throwing to another fielder from 40, 60 or 150 feet away, sometimes off balance or on the run, tests the brain-body connection for accuracy. So, how do we do it? And how can we learn to do it more consistently? In his book, The Psychology of Baseball , Mike Stadler, professor of psychology at the University of Missouri, addresses each of these questions.

There are two dimensions to think about when throwing an object at a target: vertical and horizontal. The vertical dimension is a function of the distance of the throw and the effect of gravity on the object. So the thrower's estimate of distance between himself and the target will determine the accuracy of the throw vertically. Basically, if the distance is underestimated, the required strength of the throw will be underestimated and will lose the battle with gravity, resulting in a throw that will be either too low or will bounce before reaching the target. An example of this is a fast ball which is thrown with more velocity, so will reach its target before gravity has a path-changing effect on it. On the other hand, a curve ball or change-up may seem to curve downward, partly because of the spin put on the ball affecting its aerodynamics, but also because these pitches are thrown with less force, allowing gravity to pull the ball down. In the horizontal dimension, the "right-left" accuracy is related to more to the "aim" of the throw and the ability of the thrower to adjust hand-eye coordination along with finger, arm, shoulder angles and the release of the ball to send the ball in the intended direction.

So, how do we improve accuracy in both dimensions? Prof. Stadler points out that research shows that skill in the vertical/distance estimating dimension is more genetically determined, while skill horizontally can be better improved with practice. Remember those spatial organization tests that we took that show a set of connected blocks in a certain shape and then show you four more sets of conected blocks? The question is which of the four sets could result from rotating the first set of blocks. Research has shown that athletes that are good at these spatial relations tests are also accurate throwers in the vertical dimension. Why? The thought is that those athletes are better able to judge the movement of objects through space and can better estimate distance in 3D space. Pitchers are able to improve this to an extent as the distance to the target is fixed. A fielder, however, starts his throw from many different positions on the field and has more targets (bases and cut-off men) to choose from, making his learning curve a bit longer.

If a throw or pitch is off-target, then what went wrong? Research has shown that despite all of the combinations of fingers, hand, arm, shoulder and body movements, it seems to all boil down to the timing of the finger release of the ball. In other words, when the pitcher's hand comes forward and the fingers start opening to allow the ball to leave. The timing of this release can vary by hundredths of a second but has significant impact on the accuracy of the throw. But, its also been shown that the throwing action happens so fast, that the brain could not consciously adjust or control that release in real-time. This points to the throwing action being controlled by what psychologists call an automated "motor program" that is created through many repeated practice throws. But, if a "release point" is incorrect, how does a pitcher correct that if they can't do so in real-time? It seems they need to change the embedded program by more practice.

Another component of "off-target" pitching or throwing is the psychological side of a player's mental state/attitude. Stadler identifies research that these motor programs can be called up by the brain by current thoughts. There seems to be "good" programs and "bad" programs, meaning the brain has learned how to throw a strike and learned many programs that will not throw a strike. By "seeding" the recall with positive or negative thoughts, the "strike" program may be run, but so to can the "ball" program. So, if a pitcher thinks to himself, "don't walk this guy", he may be subconsciously calling up the "ball" program and it will result in a pitch called as a ball. So, this is why sports pscyhologists stress the need to "think positively", not just for warm and fuzzy feelings, but the brain may be listening and will instruct your body what to do.


So, assuming Josh Beckett of the Red Sox is getting the ball across the plate, will the Rays hit it? That is the topic for next time when we look at hitting an object that is moving at 97 MPH and reaches you in less than half a second.

Sideline Raging Soccer Moms (and Dads!)

Visit any youth soccer field, baseball diamond, basketball court or football field and you will likely see them:  parents behaving badly.  Take a look at this Good Morning America report:

These are the extremes, but at most games, you can find at least one adult making comments at the referee, shouting at their child, or having a verbal exchange with another parent.  Thankfully, these parents represent only a small percentage of those attending the game.  Does that mean the others don't become upset at something during the game?  Usually not, as there are lots of opportunities to dispute a bad call or observe rough play or react to one of these loud parents.  

The difference is in our basic personality psyche, according to Jay Goldstein, a kinesiology doctoral student at the University of Maryland School of Public Health.  His thesis, recently published in the Journal of Applied Social Psychology (see reference below), hypothesized that a parent with "control-oriented" personality would react to events at a game more than a parent with an "autonomy-oriented" personality.

According to Goldstein, defending our ego is what usually gets us in trouble when we feel insulted or take something personally.  At youth sports games, we transfer this pride to our kids, so if someone threatens their success on the field, we often take it personally.  The control-oriented parent is more likely to react with a verbal or sometimes physical response, while an autonomy-oriented parent is better able to internalize and maintain their emotions.  This "control" vs. "autonomy" comparison has also been seen in research on "road rage", when drivers react violently to another driver's actions.

Goldstein and his team focused their research on suburban Washington soccer parents back in 2004.  They designed a survey for parents to fill out prior to watching a youth soccer game that would help categorize them as control or autonomy-oriented.  Immediately after the game ended, another survey was given to the parents that asked about any incidents during the game that made them angry on a scale of 1, slightly angry, to 7, furious.  They were also asked what action they took when they were angry.  Choices included "did nothing" to more aggressive acts like walking towards the field and/or yelling or confronting either the referee, their own child, or another player/parent.  53% of the 340 parents surveyed reported getting angry at something during the game, while about 40% reported doing something about their anger.

There was a direct and significant correlation between control-oriented parents, as identified in the pre-game survey, and the level of angry actions they took during the game.  Autonomy-oriented parents still got mad, but reported less aggressive reactions.  As Goldstein notes, “Regardless of their personality type, all parents were susceptible to becoming more aggressive as a result of viewing actions on the field as affronts to them or their kids.  However, that being said, it took autonomy-oriented parents longer to get there as compared to the control-oriented parents.”

So, now that we know the rather obvious conclusion that parents who yell at other motorists are also likely to yell at referees, what can we do about it?  Goldstein sees this study as a first step.  He hopes to study a wider cross-section of sports and socio-economic populations.  Many youth sports organizations require parents to sign a pre-season "reminder" code of conduct, but those are often forgotten in the heat of the battle on the field.  

Maybe by offering the same type of personality survey prior to the season, the "control-oriented" parents can be offered resources to help them manage their tempers and reactions during a game.  Since referees were the number one source of frustration reported by parents, two solutions are being explored by many organizations; more thorough referee training and quality control while also better training of parents on the rules of the game which often cause the confusion.

Sports contests will always be emotional, from kids' games all the way up to professionals.  Keeping the games in perspective and our reactions positive are tough things to do but when it comes to our kids, it is required.

Stats Vs. Hunches - The Moneyball Era In Sports

Most baseball general managers live in obscurity most of their careers.  Its their first hire, the manager, that usually gets the red hot spotlight, after every win and loss, second-guessed by reporters with recorders and then later by fans.  The GM puts the players on the field and lets the manager and his coaches take it from there.  Billy Beane , Oakland A's general manager, could have also been an unknown, albeit interesting, name to the baseball audience if it were not for author Michael Lewis' 2003 book, Moneyball .  Moneyball was a runaway hit (even today, 5 years later, it is #19 on Amazon's list of baseball books).  It has morphed into a full-fledged catchphrase philosophy used by everyone from Wall Street (where Beane borrowed the concept) to business consulting.  The general theme is to find undervalued assets (ballplayers) by focusing on statistics that your competition is ignoring.  Of course, you have to believe in your metrics and their predictive value for success (why has everyone else ignored these stats?)  The source of most of Beane's buried treasure of stats was Bill James and his Sabrmetrics.  Like picking undervalued stocks of soon to explode companies, Beane looked for the diamond in the dust (pun intended) and sign the player while no one was looking.  Constrained by his "small-market" team revenues, or maybe by his owners' crowbar-proof wallets, he needed to make the most from every dollar.


The combination of a GM's shrewd player selection and a manager who can develop that talent should reward the owner with the best of both worlds: an inexpensive team that wins.  This salary vs. performance metric is captured perfectly in this "real-time" graphic at BenFry.com .  It connects the updated win-loss record for each MLB team with its payroll to show the "bang for the buck" that the GMs/managers are getting from their players.  Compare the steep negative relationship for the Mets, Yankees, Tigers and Mariners with the amazing results of the Rays, Twins and Beane's own A's.  While the critics of Moneyball tactics would rightly point to the A's lack of a World Series win or even appearance, the "wins to wages" ratio has not only kept Beane in a job but given him part ownership in the A's and now the newly resurrected San Jose Earthquakes of soccer's MLS.  Beane believes the same search for meaningful and undiscovered metrics in soccer can give the Quakes the same arbitrage advantage.  In fact, there are rumours that he will focus full-time on conquering soccer as he knows there are much bigger opportunities worldwide if he can prove his methods within MLS.

In baseball, Beane relied on the uber-stat guru, Bill James, for creative and more relevant statistical slices of the game.  In soccer, he is working with some top clubs including his new favorite, Tottenham-Hotspur, of the English Premier League.  While he respects the history and tradition of the game, he is confident that his search for a competitive advantage will uncover hidden talents.  Analytical tools from companies such as Opta in Europe and Match Analysis in the U.S. have combined video with detailed stat breakdowns of every touch of the ball for every player in each game.  Finding the right pattern and determinant of success has become the key, according to Match Analysis president Mark Brunkhart as quoted earlier this year,
"You don't need statistics to spot the real great players or the really bad ones. The trick is to take the players between those two extremes and identify which are the best ones.  If all you do is buy the players that everyone else wants to buy then you will end up paying top dollar. But if you take Beane's approach - to use a disciplined statistical process to influence the selection of players who will bring the most value - then you are giving yourself the best chance of success. Who would not want to do that?"

Not to feel left out (or safe from scrutiny), the NBA now has its own sport-specific zealots.  The Association for Professional Basketball Research (APBR) devotes its members time and research to finding the same type of meaningful stats that have been ignored by players, coaches and fans.  They, too, have their own Moneyball-bible, "The Wages of Wins " by David Berri, Martin Schmidt, and Stacey Brook.  David Berri's WoW journal/blog regularly posts updates and stories related to the current NBA season and some very intriguing analysis of its players and the value of their contributions.  None other than Malcolm Gladwell, of Tipping Point and Blink fame, provided the review of Wages of Wins for the New Yorker.  One of the main stats used is something called a player's "Win Score" which attempts to measure the complete player, not just points, rebounds and assists.

Win Score (WS) = PTS + REB + STL + ½*BLK + ½*AST – FGA – ½*FTA – TO – ½*PF.   (Points, Rebounds, Steals, Blocked Shots, Assists, Field Goal Attempts, Free Throw Attempts, Turnovers, Personal Fouls)

WS is then adjusted for minutes played with the stat, WS48.  Of course, different player positions will have different responsibilities, so to compare players of different positions the Position Adjusted Win Score per 48 minutes or PAWS48 is calculated as: WS48 – Average WS48 at primary position played.  This allows an apples to apples comparison between players at a position, and a reasonable comparison of players' values across positions.  Berri's latest article looks at the fascination with Michael Beasley and some early comparisons in the Orlando Summer League. 

Will these statistics-based approaches to player evaluation be accepted by the "establishment"?  Judging by the growing number of young, MBA-educated GMs in sports, there is a movement towards more efficient and objective selection criteria.  Just as we saw in previous evidence-based coaching articles , the evidence-based general manager is here to stay.

Play Better Golf By Playing Bigger Holes

Here are some quotes we have all heard (or said ourselves) on the golf course or at the ball diamond.

On a good day:
"It was like putting into the Grand Canyon"
"The baseball looked like a beach ball up there today"

On a bad day:
"The hole was as small as a thimble"
"I don't know, it looked like he was throwing marbles"

The baseball and the golf hole are the same size every day, so are these comments meaningless or do we really perceive these objects differently depending on the day's performance? And, does our performance influence our perception or does our perception help our performance?

Jessica Witt, an assistant professor of psychological science at the University of Virginia has made two attempts at the answer. First, in a 2005 study, "See the Ball, Hit the Ball", her team studied softball players by designing an experiment that tried to correlate perceived softball size to performance. She interviewed players immediately after a game and asked them to estimate the size of the softball by picking a circle off of a board that contained several different sizes. She then found out how that player had done at the plate that day. 

As expected, the players that were hitting well chose the larger sized circles to represent the ball size, while the underperforming hitters chose the smaller circles. The team was not able to answer the question of causality, so they expanded the research to other sports.

Fast forward to July, 2008 and Witt and her team have just released a very similar study focused on golf, "Putting to a bigger hole: Golf performance relates to perceived size". Using the same experiment format, players who had just finished a round of golf were asked to pick out the perceived size of the hole from a collection of holes that varied in diameter by a few centimeters. Once again, the players who had scored well that day picked the larger holes and vice versa for that day's hackers. So, the team came to the same conclusion that there is some relationship between perception and performance, but could not figure out the direction of the effect. Ideally, a player could "imagine" a larger hole and then play better because of that visual cue.

Researchers at Vanderbilt University may have the answer. In a study, "The Functional Impact of Mental Imagery on Conscious Perception", the team led by Joel Pearson, wanted to see what influence our "Mind's Eye" has on our actual perception. In their experiment, they asked volunteers to imagine simple patterns of vertical or horizontal stripes. Then, they showed each person a pattern of green horizontal stripes in one eye and red vertical stripes in the other eye. This would induce what is known as the "binocular rivalry" condition where each image would fight for control of perception and would appear to alternate from one to the other. In this experiment, however, the subjects reported seeing the image they had first imagined more often. So, if they had imagined vertical stripes originally, they would report seeing the red vertical stripes predominantly.

The team concluded that mental imagery does have an influence over what is later seen. They also believe that the brain actually processes imagined mental images the same way it handles actual scenes. "More recently, with advances in human brain imaging, we now know that when you imagine something parts of the visual brain do light up and you see activity there," Pearson says. "So there's more and more evidence suggesting that there is a huge overlap between mental imagery and seeing the same thing. Our work shows that not only are imagery and vision related, but imagery directly influences what we see."

So, back to our sports example, if we were able to imagine a large golf hole or a huge baseball, this might affect our actual perception of the real thing and increase our performance. This link has not been tested, but its a step in the right direction. Another open question is the effect that our emotions and confidence have on our perceived task. That hole may look like the Grand Canyon, but the sand trap might look like the Sahara Desert!

Baseball on the Science Channel(!)

Just a quick follow-up for those that read the Baseball and the Brain series from a week ago. I found a great companion series from the Science Channel/Discovery Channel that goes into alot of the same detail about the physics and skills of Pitching, Hitting and Fielding.
Here's the Science Channel series: Baseball's Secret Formula
Inside that series is a great video sequence on the Physics of Baseball from the Discovery Channel.
Enjoy!

Baseball and the Brain - Fielding

With the crack of the bat, the ball sails deep into the outfield. The left-fielder starts his run back and to the right, keeping his eyes on the ball through its flight path. His pace quickens initially, then slows down as the ball approaches. He arrives just in time to make the catch. What just happened? How did this fielder know where to run and at what speed so that he and the ball intersected at the same exact spot on the field. Why didn't he sprint to the landing spot and then wait for the ball to drop, instead of his controlled speed to arrive just when the ball did? What visual cues did he use to track the ball's flight (just the ball? the ball's movement against its background? other fielder's reaction to the ball?)

Just like we learned in pitching and hitting, fielding requires extensive mental abilities involving eyes, brain, and body movements to accomplish the task. Some physical skills, such as speed, do play a part in catching, but its the calculations and estimating that our brain has to compute that we often take for granted. The fact that fielders are not perfect in this skill, (there are dropped fly balls, or bad judgments of ball flight), begs the question of how to improve? As we saw with pitching and hitting (and most sports skills), practice does improve performance. But, if we understand what our brains are trying to accomplish, we can hopefully design more productive training routines to use in practice.

(Mike Stadler, associate professor of psychology at University of Missouri, provides a great overview of current research in his book, "The Psychology of Baseball". I highly recommend it for the complete look at this topic. I'll summarize the major points here.)

One organization that does not take this skill for granted is NASA. The interception of a ballistic object in mid-flight can describe a left fielder's job or an anti-missile defense system or how a pilot maneuvers a spacecraft through a three dimensional space. In fact, a postdoctoral fellow at the NASA Ames Research Center, Michael McBeath , has been studying fly ball catching since 1995. His team has developed a rocket-science like theory named Linear Optical Trajectory to describe the process that a fielder uses to follow the path of a batted ball. LOT says the fielder will adjust his movement towards the ball so that its trajectory follows a straight line through his field of vision. Rather than compute the landing point of the ball, racing to that spot and waiting, the fielder uses the information provided by the path of the ball to constantly adjust his path so that they intersect at the right time and place. The LOT theory is an evolution from an earlier theory called Optical Acceleration Cancellation (OAC) that had the same idea but only explained the fielder's tracking behavior in the vertical dimension. In other words, as the ball leaves the bat the fielder watches the ball rise in his field of vision. If he were to stand still and the ball was hit hard enough to land behind him, his eyes would track the ball up and over his head, or at a 90 degree angle. If the ball landed in front of him, he would see the ball rise and fall but his viewing angle may not rise above 45 degrees. LOT and OAC argue that the fielder repositions himself throughout the flight of the ball to keep this viewing angle between 0 and 90 degrees. If its rising too fast, he needs to turn and run backwards. If the viewing angle is low, then the fielder needs to move forward so that the ball doesn't land in front of him. He can't always make to the landing spot in time, but keeping the ball at about a 45 degree angle by moving will help ensure that he gets there in time. While OAC explained balls hit directly at a fielder, LOT helps add the side-to-side dimension, as in our example of above of a ball hit to the right of the fielder.

The OAC and LOT theories do agree on a fundamental cognitive science debate. There are two theories of how we perceive the world and then react to it. First, the Information Processing (IP) theory likens our brain to a computer in that we have inputs, our senses that gather information about the world, a memory system that stores all of our past experiences and lessons learned, and a "CPU" or main processor that combines our input with our memory and computes the best answer for the given problem. So,IP would say that the fielder sees the fly ball and offers it to the brain as input, the brain then pulls from memory all of the hundreds or thousands of fly ball flight paths that have been experienced, and then computes the best path to the ball's landing point based on what it has "learned" through practice. McBeath's research and observations of fielders has shown that the processing time to accomplish this task would be too great for the player to react. OAC and LOT subscribe to the alternate theory of human perception, Ecological Psychology (EP). EP eliminates the call to memory from the processing and argues that the fielder observes the flight path of the ball and can react using the angle monitoring system. This is still up for debate as the IPers would argue "learned facts" like what pitch was thrown, how a certain batter hits those pitches, how the prevailing wind will affect the ball, etc. And, with EP, how can the skill differences between a young ballplayer and an experienced major leaguer be accounted for? What is the point of practice, if the trials and errors are not stored/accessed in memory?

Of course, we haven't mentioned ground balls and their behavior, due to the lack of research out there. The reaction time for a third baseman to snare a hot one-hopper down the line is much shorter. This would also argue in favor of EP, but what other systems are involved?

Game Highlights
Again, I have just touched on this subject, see Prof. Stadler's book for a much better discussion. Arguing about which theory explains a fielder's actions is only productive if we can apply the research to create better drills and practices for our players. My own layman's view is that the LOT theory is getting there as an explanation, but I'm still undecided about EP vs. IP . So many sport skills rely on some of these foundations, hence my "search for the truth" continues! As with pitching and hitting, fielding seems to improve with practice. As we move forward, we'll look at the theories behind practice and what structure they should take.

Baseball and the Brain - Hitting

Ted Williams, arguably the greatest baseball hitter of all-time, once said, "I think without question the hardest single thing to do in sport is to hit a baseball". Certainly, at the major league level, where pitches can reach 100 miles per hour, this is believable, but even at Little League, High School and College/Minor leagues, the odds are against the hitter. Looking at batting averages, 3 hits out of 10 at-bats will earn a player millions of dollars in the bigs, while averaging 4 or 5 hits out of 10 at the lower leagues will earn you some attention at the next level. As most of you know, Williams was the last major league player to hit .400 for an entire season and that was back in 1941, almost 67 years ago! In my second of three posts of the Baseball and the Brain series, we'll take a quick look at some of the theory behind this complicated skill.

Again, my main reference for these ideas is "The Psychology of Baseball" by Mike Stadler.


Some questions that come to mind regarding hitting a pitched baseball:
- What makes this task so hard? Why can't players, who practice for years and have every training technique, coach and accumulated knowledge at their disposal, perform at a consistenly higher level?
- What can be improved? Hand-eye reaction time? Knowledge of situational tendencies (what pitch is likely to be thrown in a given game situation)?

A key concept of pitching and hitting in baseball was summed up long ago by Hall of Fame pitcher Warren Spahn, when he said, “Hitting is timing. Pitching is upsetting timing.” To sync up the swing of the bat with the exact time and location of the ball's arrival is the challenge that each hitter faces. If the intersection is off by even tenths of a second, the ball will be missed. As was discussed in the Pitching post, the hitter must master the same two dimensions, horizontal and vertical. The aim of the pitch will affect the horizontal dimension while the speed of the pitch will affect the vertical dimension. The hitter's job is to time the arrival of the pitch based on the estimated speed of the ball while determining where, horizontally, it will cross the plate. The shape of the bat helps the batter in the horizontal space as its length compensates for more error, right to left. However, the narrow 3-4" barrel does not cover alot of vertical ground. So, a hitter must be more accurate judging the vertical height of a pitch than the horizontal location. So, if a pitcher can vary the speed of his pitches, the hitter will have a harder time judging the vertical distance that the ball will drop as it arrives, and swing either over the top or under the ball.

A common coach's tip to hitters is to "keep your eye on the ball" or "watch the ball hit the bat". As Stadler points out in his book, doing both of these things is impossible due to the concept known as "angular velocity". Imagine you are standing on the side of freeway with cars coming towards you. Off in the distance, you are able to watch the cars approaching your position with relative ease, as they seem to be moving at a slower speed. As the cars come closer and pass about a 45 degree angle and then zoom past your position, they seem to "speed up" and you have to turn your eyes/head quickly to watch them. This perception is known as angular velocity. The car is going a constant speed, but appears to be "speeding up" as it passes you, because your eyes need to move more quickly to keep up. This same concept applies to the hitter. The first few feet that a baseball travels when it leaves a pitcher's hand is the most important to the hitter, as the ball can be tracked by the hitter's eyes. As the ball approaches past a 45 degree angle, it is more difficult to "keep your eye on the ball" as your eyes need to shift through many more degrees of movement. Research reported by Stadler shows that hitters cannot watch the entire flight of the ball, so they employ two tactics. First, they might follow the path of the ball for 70-80% of its flight, but then their eyes can't keep up and they estimate or extrapolate the remaining path and make a guess as to where they need to swing to have the bat meet the ball. In this case, they don't actually "see" the bat hit the ball. Second, they might follow the initial flight of the ball, estimate its path, then shift their eyes to the anticipated point where the ball crosses the plate to, hopefully, see their bat hit the ball. This inability to see the entire flight of the ball to contact point is what gives the pitcher the opportunity to fool the batter with the speed of the pitch. If a hitter is thinking "fast ball", their brain will be biased towards completing the estimated path across the plate at a higher elevation and they will aim their swing there. If the pitcher actually throws a curve or change-up, the speed will be slower and the path of the ball will result in a lower elevation when it crosses the plate, thus fooling the hitter.

Game Summary
As in pitching, our eyes and brain determine much of the success we have as hitters. We took a quick look as it relates to hitting a baseball, but the same concepts apply to hitting any moving object; tennis, hockey, soccer, etc. In future posts, we'll look at practical ways to improve this tracking skill and the hand/eye/brain connection. As usual, practice will improve performance, but we want to identify the unique practice techniques which will be most effective. Tracking a moving object also applies to catching, which we'll look at next.

Baseball and the Brain - Pitching

As promised, we begin our look at the three most important technical skills of baseball: Pitching, Hitting and Catching. Each of these skills apply to other sports as well, but I thought we'd stick with the current season of baseball as the sport du jour. Again, my focus for "80 Percent Mental" is to look at sports cognition in a generic sense across all sports, occasionally digging deeper into individual sport specialties. The practical side of this is to understand how our brains and nervous system perform these skills that we often take for granted, so that we can brainstorm (yuk-yuk) on new ways to teach, practice and perfect these skills.

Pitching/Throwing
Pitching a 3" diameter baseball 46 feet (for Little League) or 60 feet, 6 inches over a target that is 8 inches wide requires an accuracy of 1/2 to 1 degree. Throwing it fast, with the pressure of a game situation makes this task one of the hardest in sports. In addition, a fielder throwing to another fielder from 40, 60 or 150 feet away, sometimes off balance or on the run, tests the brain-body connection for accuracy. So, how do we do it? And how can we learn to do it more consistently?

Questions that come to my mind regarding pitching/throwing skills and baseball include:
- Why can't a pitcher control ALL of his/her pitches? Why do some not only miss the strike zone, but are wild?
- Is the breakdown physical in the muscle sequence of the throw or is it in the connection between eyes, brain and body?

Again, one the best references I have found on this is "The Psychology of Baseball" by Mike Stadler, published by Gotham Books. Prof. Stadler digs into many of these topics and I will paraphrase from his findings. I won't do it justice here, so please put it on your reading list.

There are two dimensions to think about when throwing an object at a target: vertical and horizontal. The vertical dimension is a function of the distance of the throw and the effect of gravity on the object. So the thrower's estimate of distance between himself and the target will determine the accuracy of the throw vertically. Basically, if the distance is underestimated, the required strength of the throw will be underestimated and will lose the battle with gravity, resulting in a throw that will be either too low or will bounce before reaching the target. An example of this is a fast ball which is thrown with more velocity, so will reach its target before gravity has a path-changing effect on it. On the other hand, a curve ball or change-up may seem to curve downward, partly because of the spin put on the ball affecting its aerodynamics, but also because these pitches are thrown with less force, allowing gravity to pull the ball down. In the horizontal dimension, the "right-left" accuracy is related to more to the "aim" of the throw and the ability of the thrower to adjust hand-eye coordination along with finger, arm, shoulder angles and the release of the ball to send the ball in the intended direction.

So, looking at our first question, how do we improve accuracy in both dimensions? Prof. Stadler points out that research shows that skill in the vertical/distance estimating dimension is more genetically determined, while skill horizontally can be better improved with practice. Remember those spatial organization tests that we took that show a set of connected blocks in a certain shape and then show you four more sets of conected blocks? The question is which of the four sets could result from rotating the first set of blocks. Research has shown that athletes that are good at these spatial relations tests are also accurate throwers in the vertical dimension. Why? The thought is that those athletes are better able to judge the movement of objects through space and can better estimate distance in 3D space. Pitchers are able to improve this to an extent as the distance to the target is fixed. A fielder, however, starts his throw from many different positions on the field and has more targets (bases and cut-off men) to choose from, making his learning curve a bit longer.

If a throw or pitch is off-target, then what went wrong? Prof. Stadler collects many different studies that review the possible physiological/mechanical reasons for "bad throws". Despite all of the combinations of fingers, hand, arm, shoulder and body movements, it seems to all boil down to the timing of the finger release of the ball. In other words, when the pitcher's hand comes forward and the fingers start opening to allow the ball to leave. The timing of this release can vary by hundredths of a second but has significant impact on the accuracy of the throw. But, its also been shown that the throwing action happens so fast, that the brain could not consciously adjust or control that release in real-time. This points to the throwing action being controlled by what psychologists call an automated "motor program" that is created through many repeated practice throws. But, if a "release point" is incorrect, how does a pitcher correct that if they can't do so in real-time? It seems they need to change the embedded program by more practice.

Another component of "off-target" pitching or throwing is the psychological side of a player's mental state/attitude. Stadler identifies research that these motor programs can be called up by the brain by current thoughts. There seems to be "good" programs and "bad" programs, meaning the brain has learned how to throw a strike and learned many programs that will not throw a strike. By "seeding" the recall with positive or negative thoughts, the "strike" program may be run, but so to can the "ball" program. So, if a pitcher thinks to himself, "don't walk this guy", he may be subconsciously calling up the "ball" program and it will result in a pitch called as a ball. So, this is why sports pscyhologists stress the need to "think positively", not just for warm and fuzzy feelings, but the brain may be listening and will instruct your body what to do.

Game Summary
I've only touched the surface for this topic. We'll see some of these themes in the hitting and catching posts that are coming up. One useful takeaway here for youth coaches is that some players will have a genetic advantage in throwing and may be your "natural" pitchers. As we dig deeper into these topics, we will be able pull out more practical tips for players and coaches.

Baseball and the Brain

Its April, so that means baseball diamonds all over the country are filling up with teams getting ready for another season. Pitching, fielding and batting skills are being tested, evaluated and trained. So, this is a logical place to start to dig into the theory, teachings and tips of three of the technical skills area I mentioned in the Sports Cognition Framework. As I've mentioned before, I'm learning as I go and rely heavily on the books and papers I read on these topics. This look at baseball is no exception.
At the top of my baseball list is "The Psychology of Baseball" by Mike Stadler, published by Gotham Books. Mike, an associate professor of cognitive psychology at the University of Missouri, does a great job of combining baseball stories with the cognitive theories used to explain his favorite sport. I highly recommend it.
Here's my game plan for this "World Series" of posts:
Part 1 - Pitching/Throwing: Pitching a 3" diameter baseball 46 feet (for Little League) or 60 feet, 6 inches over a target that is 8 inches wide requires an accuracy of 1/2 to 1 degree. Throwing it fast, with the pressure of a game situation makes this task one of the hardest in sports. In addition, a fielder throwing to another fielder from 40, 60 or 150 feet away, sometimes off balance or on the run, tests the brain-body connection for accuracy.
Part 2 - Hitting: As Ted Williams claimed many times, hitting a baseball thrown at 90+ MPH that may dip, curve or go in a straight line is "the hardest" sport skill in sports. As we'll see, its all about estimating speed and timing, with calculations far too difficult to be consciously calculated in the very short window of time between the pitcher's release and the ball crossing the plate (.4 to .6 seconds)
Part 3 - Fielding: Before the right fielder can make that deadly accurate throw to third base to nab the runner, he must first catch the flyball hit 50 feet to his right and slightly behind, with a swirling wind changing the fight path of the ball, while running across the field while keeping his eyes on the ball. Again, the eye-brain-muscular connection must make on the fly calculations to get that glove in the exact spot where the ball will land. Most of the time it seems so routine that we don't think of the effort involved. Other times, we are amazed at how a major league player, who has caught thousands of fly balls in his life can make the occassional error. Of course, at the Little League level, errors are more common. We'll learn that practice does improve performance over time, I would like to know how. And, once we understand the learning process, can we design better practices and teach better techniques to speed up that player's skill level.
