Marathon Runners Mull the ‘D Word’
This is the time of year, after marathoners have logged their longest miles, that any kind of pain, nagging or excruciating, can send runners into a panic about whether they will make it to the starting line. Or if they should even try...
Faster tunes make you bike faster, even if it hurts a bit more Researchers have been studying how music and other “distractions” affect exercise performance for decades (see here, for instance), hoping to trick us into pushing a little harder without realizing it. One of the factors they’ve looked at extensively is the speed of the music — the idea that faster tempos make us pick up the pace. The problem is that the effects of tempo tend to be swamped by the effect of whether the subjects in the experiment like the particular tunes selected for them...
How Do Marathons Affect Your Heart?
Last year the European Heart Journal published a study that continues to prompt discussion among researchers who work with marathoner runners and those, many of them the same researchers, who run marathons. In the study, German scientists scanned the hearts of 108 experienced, male distance runners in their fifties, sixties and seventies. By standard measures, the group’s risk for heart problems was low. But when the researchers studied the runners’ scan results, they found that more than a third of the men showed evidence of significant calcification or plaque build-up in their heart arteries. Several also had scarring of some of the tissue in their hearts...
The Eyes Have It - Is visual training the sports world's next big thing?
Seattle Mariners first baseman Russell Branyan began this season on a tear. In interviews, Branyan credited his newfound success in large part to a piece of software that runs on an ordinary laptop. "I think it's helped me really pinpoint and focus on the ball," Branyan said of the Vizual Edge program, which offers a variety of exercises to train and sharpen visual skills. "I see the ball exactly where it is. I don't want to say it's all because of this. … But, I mean, I was a .230 hitter."
Watch Out Gatorade, Powerade, Accelerade! Mother Nature's Entered the Game!
"I'm convinced more than ever that Mother Nature is a runner. I've recently hailed Mother Nature's "natural sports drink"—coconut water—and its health benefits, especially how its naturally high level of potassium helps keep my calf cramps at bay on long runs. Well, it appears that Mother Nature has expanded her line of sports drinks..."
Young Athletes and Women More Likely to Have Second ACL Surgery Within a Year According to one of the largest studies ever conducted on the outcomes of ACL surgery, patients under 40 and women are both more likely to have second knee surgery within a year of an ACL repair. Investigators looked at surgical outcomes in 70,000 patients who had ACL reconstruction surgery from 1997 to 2006 in New York state. The results, published in the October 2009 issue of The Journal of Bone and Joint Surgery, found the following...
Despite Size, NFL Players Not More Likely To Develop Heart Disease, Even After Retirement
Former professional football players with large bodies don't appear to have the same risk factors for heart disease as their non-athletic counterparts, UT Southwestern Medical Center researchers have found in studying a group of National Football League (NFL) alumni....
Here's a new feature of Sports Are 80 Percent Mental: A weekly round-up of some of the best blog posts, articles and other interesting stuff that I've found on sports science and fitness research. If you find anything else, please just add it as a comment to this post!
Aging Muscles: 'Hard To Build, Easy To Lose' Have you ever noticed that people have thinner arms and legs as they get older? As we age it becomes harder to keep our muscles healthy. They get smaller, which decreases strength and increases the likelihood of falls and fractures. New research is showing how this happens — and what to do about it...
Back to Basics: Yes, Sergeant! If Mark Roozen, a personal trainer in Colorado Springs, set his group conditioning classes to music, the playlist could start with “I’ve Been Working on the Railroad.” Mr. Roozen’s routines are as likely to incorporate logs, wheelbarrows and sandbags as circuit machines, Pilates equipment and other gym staples... Often Overlooked but Key to Marathon Success: The Base Doesn't sound glamorous, does it? Isn't snazzy sounding. Isn't flashy. But, man is it important. One of the biggest mistakes new marathoners make is overlooking the base mileage needed before beginning any kind of marathon training...
Real-Time Feedback System For Alpine Skiers Help Improve Performance Researchers have developed an effective real-time performance management and feedback system for alpine ski racers that allow skiers to better understand their carved turning skills and improve their performance...
Caster Semenya - cover-ups, lies and confusion For those who have not been following this astonishing story, Athletics South Africa boss Leonard Chuene admitted on the weekend that he lied about not having prior knowledge of the doubt around Caster Semenya, and has admitted that he authorized tests on Semenya in South Africa before the team left for the IAAF World Champs in Berlin...
Slushies: the new weapon for exercising in heat Reading up on Australian sports research for an upcoming magazine story, I came across this little nugget about dealing with competition in hot conditions. The Aussies have been leaders in research on “pre-cooling” to lower body temperature before starting extended exercise in the heat. They introduced ice vests at the 1996 Olympics (which have since become widely used commercial products), and in 2004 brought big bathtubs full of ice-water to the Athens Olympic venues, actually immersing their endurance athletes shortly before their competitions...
Phys Ed: Can Vitamin D Improve Your Athletic Performance? When scientists at the Australian Institute of Sport recently decided to check the Vitamin D status of some of that country’s elite female gymnasts, their findings were fairly alarming. Of the 18 gymnasts tested, 15 had levels that were “below current recommended guidelines for optimal bone health,” the study’s authors report. Six of these had Vitamin D levels that would qualify as medically deficient. Unlike other nutrients, Vitamin D can be obtained by exposure to ultraviolet radiation from sunlight, as well as through foods or supplements. Of course, female gymnasts are a unique and specialized bunch, not known for the quality or quantity of their diets, or for getting outside much...
