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.

Watching Sports Is Good For Your Brain

When was the last time you listened to a sporting event on the radio? If given a choice between watching the game on a big screen plasma in HD or turning on the AM radio, most of us would probably choose the visual sensation of television. But, for a moment, think about the active attention you need in order to listen to a radio broadcast and interpret the play-by-play announcer's descriptions. As you hear the words, your "mind's eye" paints the picture of the action so you can imagine the scene and situations. Your knowledge of the game, either from playing it or watching it for years helps you understand the narrative, the terms and the game's "lingo".


Now, imagine that you are listening to a broadcast about a sport you know nothing about. Hearing Bob Uecker or Vin Scully say, "With two out in the ninth, the bases are loaded and the Brewers' RBI leader has two strikes. The infield is in as the pitcher delivers. Its a hard grounder to third that he takes on the short hop and fires a bullet to first for the final out." If you have no baseball-specific knowledge, those sentences are meaningless. 

However, for those of us that have grown up with baseball, that description makes perfect sense and our mind's eye helped us picture the scene. That last sentence about the "hard grounder" and the thrown "bullet" may have even triggered some unconscious physical movements by you as your brain interpreted those action phrases. That sensorimotor reaction is at the base of what is called "embodied cognition". 
 
Sian Beilock, associate professor of psychology and leader of the Human Performance Lab at the University of Chicago, defined the term this way: "In contrast to traditional views of the mind as an abstract information processor, recent work suggests that our representations of objects and events are grounded in action. That is, our knowledge is embodied, in the sense that it consists of sensorimotor information about potential interactions that objects or events may allow." She cites a more complete definition of the concept in Six Views of Embodied Cognition by Margaret Wilson. Another terrific overview of the concept is provided by science writer Drake Bennet of the Boston Globe in his article earlier this year, "Don't Just Stand There, Think".


In a study released yesterday, "Sports Experience Changes the Neural Processing of Action Language", Dr. Beilock's team continued their research into the link between our learned motor skills and our language comprehension about those motor skills. Since embodied cognition connects the body with our cognition, the sports domain provides a logical domain to study it.


Their initial look at this concept was in a 2006 study titled, "Expertise and its embodiment: Examining the impact of sensorimotor skill expertise on the representation of action-related text", where the team designed an experiment to compare the knowledge representation skill of experienced hockey players and novices. Each group first read sentences describing both hockey-related action and common, "every-day" action, (i.e. "the referee saw the hockey helmet on the bench" vs. "the child saw the balloon in the air"). They were then shown pictures of the object mentioned in the sentences and were asked if the picture matched the action in the sentence they read.

Both groups, the athletes and the novices, responded equally in terms of accuracy and response time to the everyday sentences and pictures, but the athletes responded significantly faster to the hockey-specific sentences and pictures. The conclusion is that those with the sensorimotor experience of sport give them an advantage of processing time over those that have not had that same experience.


Now, you may be saying, "Ya' think!?" to this somewhat obvious statement that people who have played hockey will respond faster to sentence/picture relationships about hockey than non-hockey players. Stay with us here for a minute, as the 2006 study set the groundwork for Beilock's team to take the next step with the question, "is there any evidence that the athletes are using different parts of their brain when processing these match or no match decisions?" The link between our physical skill memory and our language comprehension would be at the base of the embodied cognition theory. 

So, in the latest research, the HPL team kept the same basic experimental design, but now wanted to watch the participants' brain activity using fMRI scanning. This time, there were three groups, hockey players, avid fans of hockey and novices who had no playing or viewing experience with hockey at all. First, all groups passively listened to sentences about hockey actions and also sentences about everyday actions while being monitored by fMRI.  Second, outside of the fMRI scanner, they again listened to hockey-related and everyday-related action sentences and then were shown pictures of hockey or every day action and asked if there was a match or mis-match between the sentence and the picture.


This comprehension test showed similar results as in 2006, but now the team could try to match the relative skill in comprehension to the neural activity shown in the fMRI scans when listening. Both the players and the fans showed increased activity in the left dorsal premotor cortex, a region thought to support the selection of well-learned action plans and procedures. 

You might be surprised that the fans' brains showed activity in the same regions as the athletes. We saw this effect in a previous post, "Does Practice Make Perfect", where those that practiced a new dance routine and those that only watched it showed similar brain area activity. On the other side, the total novices showed activity in the bilateral primary sensory-motor cortex, an area typically known for carrying out step by step instructions for new or novel tasks. 

So, the interesting finding here is that those with experience, either playing or watching, are actually calling on additional neural networks in their brains to help their normal language comprehension abilities. In other words, the memories of learned actions are linked and assist other cognitive tasks. That sounds pretty much like the definition of embodied cognition and Dr. Beilock's research has helped that theory take another step forward. In her words, "Experience playing and watching sports has enduring effects on language understanding by changing the neural networks that support comprehension to incorporate areas active in performing sports skills."


Take pride in your own brain the next time you hear, "Kobe dribbles the ball to the top of the key, crosses over, drives the lane, and finger rolls over Duncan for two." If you can picture that play in your mind, your left dorsal premotor cortex just kicked into gear!

Lifting The Fog Of Sports Concussions

A concussion, clinically known as a Mild Traumatic Brain Injury (MTBI), is one of the most common yet least understood sports injuries.  According to the Centers for Disease Control, there are as many as 300,000 sports and recreation-related concussions each year in the U.S., yet the diagnosis, immediate treatment and long-term effects are still a mystery to most coaches, parents and even some clinicians.  

The injury can be deceiving as there is rarely any obvious signs of trauma.  If the head is not bleeding and the player either does not lose consciouness or regains it after a brief lapse, the potential damage is hidden and the usual "tough guy" mentality is to "shake it off" and get back in the game.


Leigh Steinberg, agent and representative to some of the top professional athletes in the world (including NFL QBs Ben Roethlisberger and Matt Leinart), is tired of this ignorance and attitude.  "My clients, from the day they played Pop Warner football, are taught to believe ignoring pain, playing with pain and being part of the playing unit was the most important value," Steinberg said, "I was terrified at the understanding of how tender and narrow that bond was between cognition and consciousness and dementia and confusion".  Which is why he was the keynote speaker at last week's "New Developments in Sports-Related Concussions" conference hosted by the University of Pittsburgh Medical College Sport Medicine Department in Pittsburgh. 

Leading researchers gathered to discuss the latest research on sports-related concussions, their diagnosis and treatment.  "There's been huge advancement in this area," said Dr. Micky Collins, the assistant director for the UPMC Sports Medicine Program. "We've learned more in the past five years than the previous 50 combined."

So, what is a concussion?  The CDC defines a concussion as "a complex pathophysiologic process affecting the brain, induced by traumatic biomechanical forces secondary to direct or indirect forces to the head."  Being a "mild" form of traumatic brain injury, it is generally believed that there is no actual structural damage to the brain from a concussion, but more a disruption in the biochemistry and electrical processes between neurons.  

The brain is surrounded by cerebrospinal fluid, which is supposed to provide some protection from minor blows to the head.  However, a harder hit can cause rotational forces that affect a wide area of the brain, but most importantly the mid-brain and the reticular activating system which may explain the loss of consciousness in some cases.  

For some athletes, the concussion symptoms take longer to disappear in what is known as post-concussion syndrome.  It is not known whether this is from some hidden structural damage or more permanent disruption to neuronal activity.  Repeated concussions over time can lead to a condition known as dementia pugilistica, with long-term impairments to speech, memory and mental processing.

After the initial concussion, returning to the field before symptoms clear raises the risk of second impact syndrome, which can cause more serious, long-term effects.  As part of their "Heads Up" concussion awareness campaign, the CDC offers this video story of Brandon Schultz, a high school football player, who was not properly diagnosed after an initial concussion and suffered a second hit the following week, which permanently changed his life.  Without some clinical help, the player, parents and coach can only rely on the lack of obvious symptoms before declaring a concussion "healed".  

However, making this "return to play" decision is now getting some help from some new post-concussion tests.  The first is a neurological skills test called ImPACT (Immediate Post-Concussion and Cognitive Testing) created by the same researchers at UPMC.  It is an online test given to athletes after a concussion to measure their performance in attention span, working memory, sustained and selective attention time, response variability, problem solving and reaction time.  Comparing a "concussed" athlete's performance on the test with a baseline measurement will help the physician decide if the brain has healed sufficiently.

However, Dr. Collins and his team wanted to add physiological data to the psychological testing to see if there was a match between brain activity, skill testing and reported symptoms after a concussion.  In a study released last year in the journal Neurosugery, they performed functional MRI (fMRI) brain imaging studies on 28 concussed high-school athletes while they performed certain working memory tasks to see if there was a significant link between performance on the tests and changes in brain activation.  They were tested about one week after injury and again after the normal clinical recovery period.

“In our study, using fMRI, we demonstrate that the functioning of a network of brain regions is significantly associated with both the severity of concussion symptoms and time to recover,” said Jamie Pardini, Ph.D., a neuropsychologist on the clinical and research staff of the UPMC concussion program and co-author of the study.  
 "We identified networks of brain regions where changes in functional activation were associated with performance on computerized neurocognitive testing and certain post-concussion symptoms,” Dr. Pardini added. "Also, our study confirms previous research suggesting that there are neurophysiological abnormalities that can be measured even after a seemingly mild concussion.” 

Putting better assessment tools in the hands of athletic trainers and coaches will provide evidence-based coaching decisions that are best for the athlete's health.  Better decisions will also ease the minds of parents knowing their child has fully recovered from their "invisible" injury.

Single Sport Kids - When To Specialize

So, your grade school son or daughter is a good athlete, playing multiple sports and having fun at all of them. Then, you hear the usual warning, either from coaches or other parents; "If you want your daughter to go anywhere in this sport, then its time to let the other sports go and commit her full-time to this one." The logic sounds reasonable. The more time spent on one sport, the better she will be at that sport, right? Well, when we look at the three pillars of our Sports Cognition Framework, motor skill competence, decision making ability, and positive mental state, the question becomes whether any of these would benefit from playing multiple sports, at least in the early years of an athlete (ages 3-12)? It seems obvious that specific technical motor skills, (i.e. soccer free kicks, baseball bunting, basketball free throws) need plenty of practice and that learning the skill of shooting free throws will not directly make you a better bunter. On the other end, learning how to maintain confidence, increase your focus, and manage your emotions are skills that should easily transfer from one sport to another. That leaves the development of tactical decision making ability as the unknown variable. Will a young athlete learn more about field tactics, positional play and pattern recognition from playing only their chosen sport or from playing multiple related sports?

Researchers at the University of Queensland, Australia learned from previous studies that for national team caliber players there is a correlation between the breadth of sport experiences they had as a child and the level of expertise they now have in a single sport. In fact, these studies show that there is an inverse relation between the amount of multi-sport exposure time and the additional sport-specific training to reach expert status. In plain English, the athletes that played several different (but related) sports as a child, were able to reach national "expert" level status faster than those that focused only one sport in grade school . Bruce Abernethy, Joseph Baker and Jean Cote designed an experiment to observe and measure if there was indeed a transfer of pattern recognition ability between related sports (i.e. team sports based on putting an object in a goal; hockey, soccer, basketball, etc.)

They recruited two group of athletes; nationally recognized experts in each of three sports (netball, basketball and field hockey) who had broad sports experiences as children and experienced but not expert level players in the same sports whose grade school sports exposure was much more limited (single sport athletes). (For those unfamiliar with netball, it is basically basketball with no backboards and few different rules.) The experiment showed each group a video segment of an actual game in each of the sports. When the segment ended the groups were asked to map out the positions and directions of each of the players on the field, first offense and then defense, as best they could remember from the video clip. The non-expert players were the control group, while the expert players were the experimental groups. First, all players were shown a netball clip and asked to respond. Second, all were shown a basketball clip and finally the hockey clip. The expectation of the researchers was that the netball players would score the highest after watching the netball clip (no surprise there), but also that the expert players of the other two sports would score higher than the non-expert players. The reasoning behind their theory was that since the expert players were exposed to many different sports as a child, there might be a significant transfer effect between sports in pattern recognition, and that this extra ability would serve them well in their chosen sport.

The results were as predicted. For each sport's test, the experts in that sport scored the highest, followed by the experts in the other sports, with the non-experts scoring the poorest in each sport. Their conclusion was that there was some generic learning of pattern recognition in team sports that was transferable. The takeaway from this study is that there is benefit to having kids play multiple sports and that this may shorten the time and training needed to excel in a single sport in the future.

So, go ahead and let your kids play as many sports as they want. Resist the temptation to "overtrain" in one sport too soon. Playing several sports certainly will not hurt their future development and will most likely give them time to find their true talents and their favorite sport.

Federer and Nadal Can See the Difference

Watching Roger Federer and Rafael Nadal battle it out in the French Open final and now again in the Wimbledon final, I started thinking more about the interceptive timing task requirements of each of their visuomotor systems... yeah, right. C'mon, I just needed a good opening line for this post.


However, other than a 120 mph tennis serve, take a second to think about all of the different sports that send an object flying at you at very high speeds that you not only have to see, but also estimate the speed of the object, the movement of the object and what you want to do with the object once it gets to you.



Some examples are:
- a hockey puck at a goalie (70-100 mph)
- a baseball pitch at a batter (70-100 mph)
- a soccer ball kicked at a keeper (60-90 mph)


Previously, we took a look at this in baseball and in soccer and also discussed the different types of visual skills in sports. There, we broke it down into three categories:

- Targeting tasks
- Interceptive timing tasks
- Tactical decision making tasks

The second category, interceptive timing tasks, deals with the examples above; stuff coming at you fast and you need to react. There are three levels of response that take an increasing level of brainpower.

First, there is a basic reaction, also known as optometric reaction. In other words, "see it and get out of the way". Next, there is a perceptual reaction, meaning you actually can identify the object coming at you and can put it in some context (i.e. that is a tennis ball coming at you and not a bird swooping out of the sky).

Finally, there is a cognitive reaction, meaning you know what is coming at you and you have a plan of what to do with it (i.e. return the ball with top-spin down the right line). This cognitive skill is usually sport-specific and learned over years of tactical training. Obviously, for professional tennis players, they are at the expert cognitive stage and have a plan for most shots. Federer's problem was that Nadal had better plans.

But, in order to reach that cognitive stage, they first need to have excellent optometric and perceptual skills. Can those skills be trained? Or are the best tennis players born with naturally better abilities? Did their training make them better tennis players or are they better players because of some natural skills?


Leila Overney and her team at the Brain Mind Institute of Ecole Polytechnique Federale de Lausanne (EPFL) recently studied whether expert tennis players have better visual perception abilities than other athletes and non-tennis players. Typically, motor skill research compares experts to non-experts and tries to deduce what the experts are doing differently to excel.

In this study, an additional category was added. Overney wanted to see if the perceptual skills of the tennis players were significantly more advanced than athletes of a similar fitness level, (in this case triathletes), to eliminate the variable of "fitness", and also more advanced than novice tennis players (the typical comparison). To eliminate the cognitive knowledge difference between the groups, she used seven non-sport specific visual tests. Please see the actual study for details of all the tests.

The bottom line of the results was that certain motion detection and speed discrimination skills were better in the tennis players (in other words, being able to track a ball coming at you and its movement side to side).


So, the expert tennis players were better at tracking balls coming at them than triathletes and non-tennis players.... seems pretty obvious(!) But, these results are a first step to answering the question of "can these skills be trained"? We see that there is, indeed, a difference in ability level between expert players and athletes that are in similar shape and competitive spirit. Now, the question becomes, "how did these tennis players acquire a higher level of perception skill"? Was it "nature or nurture", "genetically gifted or trained through practice"?

See The Ball, Be The Ball - Vision and Sports

The whistle blows and Shaq goes to the line again after being fouled on purpose for the fourth time. And, again, we watch as he takes that awkward stance, looks at the basket and then clanks one of the back of the rim. We wonder how hard this can be... just aim and shoot! Isn't it that simple? Well, not exactly. In our introduction to this series I mentioned the research of Dr. Joan Vickers and her concept of the "Quiet Eye". In her book, Perception, Cognition and Decision Training, she describes this visual targeting pathway:


"...the visual pathway begins when information is registered on the eye's retina by the focal and ambient systems, then travels to the back of the head along the optic nerve and radiates to the occipital cortex, where visual information is registered as billions of features. These then race in parallel fashion both to the top of the head to the parietal cortex (dorsal) and along the sides of the head to the temporal (ventral) areas. There is an integration of information in the somatosensory cortex as the information goes to the frontal cortex, where the goals and intentions reside and plans are formulated for the specific event that is occurring. The flow of information then goes to the premotor and motor cortex at the top of the head before going down the spinal cord to the effectors." P.26


This same process repeats constantly during any athletic event and it is the most critical determinant of the outcome of the game. Just think about the types of visual work that needs to be done by an athlete (as defined by Dr. Vickers):

1. Targeting Tasks - being able to fixate on a target, fixed or moving, to be able to throw, kick or send an object towards it. (i.e. Shooting or passing a baseball, football, basketball, soccer ball, hockey puck, etc.)

2. Interceptive Timing Tasks - being able to recognize, track and finally control an object as it comes at you (aka "catching")

3. Tactical Decision Making Tasks - being able to take in an environmental scan of the field/court and recognize patterns of all the moving objects (i.e. a quarterback scanning his receivers and choosing the best option for a pass).

All of these scenarios require the athlete to focus or "gaze" on the right points in the environment and ignore the rest of the scene. Dr. Vickers' work has been to observe athletes of different skill levels, expert and non-expert, and define the "best practices" of visual control so that the non-expert athletes can be coached to better performance. Her research lab uses "eye-trackers" (see photo) to monitor the focus and gaze of the athlete's pupils as they perform their skills.

For example, she has found that expert baseball hitters focus on the release point of the ball exclusively, rather than random fixations on the pitcher's arm, head, jersey, etc. She found that expert golf putters focus on a specific point on the cup, then a specific point on the back of the ball and remain fixated on the point on the ball after the ball has left the putter blade.

Novices allow their gaze to wander from the ball to the hole, without a very specific focal point on either the cup or the ball. The term "Quiet Eye" comes from these observations that expert performers have consciously chosen points in their space to focus on rather than allowing their eyes to wander and fixate on multiple points (i.e. a "noisy" eye).


So, why does the Quiet Eye work? When we fixate on key points in our field of vision, how does this help our neuromuscular systems perform better? The subconscious part of our brain may be recognizing a pattern that we have seen and experienced before and directing our movements based on this information. Some have called this "muscle memory", meaning our brain has learned through repetition and practice how to throw a ball to a moving receiver at that distance and speed, and so, when presented with a similar scenario, knows what to do. Think about when you shoot a jump shot and sometimes you get that sensation, as soon as it leaves your hand, that the ball is going in. Your brain may be telling you that, based on past experience, when you've executed the same aim and same muscle movement then the ball has gone in.

This takes us back to the discussion we had in our previous post on baseball fielding regarding theories of perception-action combinations. The Information Processing model claims that we perceive the environment first through our senses, primarily our vision. Then, we access our memory to find the rules, suggestions and knowledge that we have gained from past experiences and these memories guide our action in the moment.

The Ecological Psychology model removes the memory access step and claims that our perception of the environment leads directly to our actions, as there is not enough time to access our lessons. If that is true, then how does the Quiet Eye help us? It seems the Quiet Eye is what we need to connect the current scenario (standing on the free throw line looking at the basket) with our lessons learned from the past (how we made this shot hundreds of times before). Research continues on this question and I'm sure we'll come back to this in future posts.


Next time, I will take a look at Dr. Vickers' "Decision Training Model", which builds on the Quiet Eye theory to train athletes to improve their tactical in-game decision making. We will look at the athletes who are known as having good "vision of the field" and how to raise everyone's game to that level.

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.

What is the Toughest Sport to Play?

Ask any athlete, weekender or pro, which sport requires the most overall skill and talent to play and you would get many different answers. It depends on the mix of "skills" used in the comparison. Are we talking raw physical skills like speed and power, technical skills like throwing and catching or mental skills like determination and nerve? The debate could be endless, as there would be apples to oranges comparisons, but its worth a look. ESPN, of all people, took this challenge head-on and actually put together a reasonable survey of experts, (OK, some of whom were ESPN'ers), to rank the 60 sports along 10 different criteria. Check it out at the ESPN site here .
The surprising result was that boxing, the sweet science, ranked number one, edging out hockey but comfortably ahead of football and basketball. Again, the analysis is across all 10 variables, and boxing scored in the top 5 in five different categories: Endurance, Strength, Power, Nerve and Durability. Of course, boxing ranks low in Speed, Agility and Flexibility. But, I know my reaction to boxing's top spot was probably similar to most others: Two strong guys bashing each other until they drop to the ground or until its over, which then would be decided by judges on who did the most bashing. In other words, I don't have the proper respect for the sport that apparently I should.
What really intrigues me about these rankings are the categories themselves and the ability to sort the list of sports by each category. There are the "brainy sports", hockey, auto racing(!) and soccer, rated high in Analytic Aptitude. Baseball and tennis score high in the "technical skill" of Hand-Eye Coordination. In the "positive mental state" group are those sports that score high in Endurance, Durability, and what the survey calls Nerve, or the ability to overcome fear. Sports high in this group include the "long distance" sports of cycling, running and swimming; the "tough guy" sports of boxing, football, hockey and rugby; and the "no fear" sports of auto racing, rodeo, alpine skiing and boxing.
Take a look at the table they have listed. Its fun to sort on different columns and then think through the logic. Let me know if you agree or disagree with the "experts"!

Sorting the Skill Sets

OK, so before I take on the whole world of cognitive psychology, kinesiology, neuromuscular patterns and the motor skill development (yikes!), I want to try to categorize the different distinct set of skills that seem obvious to my untrained eye. While each sport is different in its rules, objectives and layout, the underlying skills required of the athletes seem to overlap. My early theory is that if athletes, especially young athletes, focus on the fundamentals of each core skill set, then they will be able to transfer those "mental maps" to other sports. Also, when considering the pieces necessary to perform a skill, it will be easier to break down the variations of the skill of each sport and get to the underlying mechanics.

So, here is my "Outline of Sport Skills" that will help organize our research and discovery:

First, a definition from Merriam-Webster (M-W.com) of skill: the ability to use one's knowledge effectively and readily in execution or performance b: dexterity or coordination especially in the execution of learned physical tasks

Throwing (M-W.com: to propel through the air by a forward motion of the hand and arm) Sample sports: baseball, football, cricket, basketball, bowling, etc.

One qualifier that I would add is to throw "at a target", which would differ than just throws for distance (i.e. shot/discus/javelin). The skill is two-dimensional as it involves judgment of distance and lateral accuracy.
Research questions would include:
- How is distance to target determined?
- How is lateral accuracy determined? (i.e. right-left, up-down target accuracy)
- If we include a soccer kick in this category, how are foot-eye coordination different than hand-eye?

Catching (M-W.com: to grasp and hold on to (something in motion)) Sample sports: baseball, football, cricket, basketball, hockey, etc.

As familiar as we are with the act of catching a ball, we rarely dig deep into the true skill involved.
Research questions would include:
- How does the athlete judge the flight of the object (ball)?
- What are the visual cues that we use to reposition ourselves to meet the object at the right place and time to make the catch?
- What tactile cues to we use to close the grasp on the object?

Hitting (M-W.com: to strike (as a ball) with an object (as a bat, club, or racket) so as to impart or redirect motion) Sample sports: baseball, golf, tennis, hockey, etc.

There are two variations: hitting a stationary (golf) vs. a moving object (baseball, tennis, hockey, cricket)
Research questions would include:
- Are the object tracking skills of Catching similar to those needed in Hitting?
- How does the neuro-motor connection adjust to the use of an object?

These three sets of skills cover most of the necessary situations in most major "goal-oriented" sports as opposed to the repetitive action sports of running, swimming, cycling, etc. Learning the commonalities at a very basic level should offer ideas of how to improve these core abilities through exercises and techniques.
