Jet Lag and Baseball (MLB) Performance
by William Yates, M.D. in Brain Posts
Abrupt changes in the biological clock or circadian rhythm are noted to contribute to significant cognitive and psychomotor impairments.One practical area for this effect to potentially be important is in the area of sports performance.Alex Song and colleagues recently completed an interesting study of major league baseball (MLB) performance related to team travel patterns.The major leagues are divided into regional divisions (western, central and eastern) to minimize length of travel to and fro........

Weight Training Boosts Brain Size and Performance
by William Yates, M.D. in Brain Posts
Aerobic exercise increases brain blood flow and has demonstrated beneficial effects on cognition.The effects of weight training exercise on the brain is less frequently studied. Hence, we know little about the effect and mechanism of weight training on brain function and performance.A recent study provides some needed insight on this topic.A study by C Suo and colleagues from Australia examined the effects of resistance training and cognitive skills training on brain structure and function.The k........

Sorry, I Don't Drink
by Mark Lasbury in As Many Exceptions As Rules
Koalas don’t drink a lot of water, but the spinifex hopping mouse and kangaroo rat put him to shame. They never drink. What water they need they get from the seeds they eat and from the fact that they conserve water amazingly well – including the water that they produce during metabolism. Adult mayflies don’t drink either – they don’t have working mouthparts! Of course, some only live a few minutes as adults, so it may not be that big a deal.... Read more »

Elite Cyclists and Brain Fatigue Resistance
by William Yates, M.D. in Brain Posts
In a Brain Post from 2012 I reviewed a study of fatigue in elite athletic performance. This study supported a key role in the brain insula in regulating the perception of exercise-induced fatigue. You can access this post by clicking HERE.An update on this topic was recently published in PloS One by a research team in Australia.This study compared performance on a cognitive task after extreme 20 minute cycling time trial. Professional cyclists were compared to recreational cyclists on the Stroop........ Read more »

Managing Fatigue in Match-Play Tennis
by William Yates, M.D. in Brain Posts
The 2015 U.S. Tennis Open is in full swing and I ran into an interesting recent manuscript summarizing fatigue in tennis.Fatigue has multiple elements including changes in muscle performance, blood markers of lactic acid and other compounds as well as brain central perception factors.Long multi-set matches can last four or five hours. Obviously, at the end of this type of exertion, players have had to adjust to effects of significant fatigue.Reid and Duffield review the key elements of fatigue i........ Read more »

Fitness Boosts White Matter Integrity in Aging
by William Yates, M.D. in Brain Posts
Cardiovascular fitness has been correlated with a variety of beneficial effects on brain structure and cognition.These correlations have not proven causality but they do support continued imaging and brain function studies.Scott Hayes from the VA Boston Healthcare System and Boston School of Medicine recently published an information study on this topic.Brain white matter integrity is now open for study using diffusion tensor imaging, available from high-resolution magnetic resonance imaging (MR........

Physical Exercise Effects on Brain EEG
by William Yates, M.D. in Brain Posts
There are a variety of methods to study the effects on exercise on brain function. Brain imaging techniques such as fMRI provides a new tool to search for regional effects of acute and chronic exercise.Another tool that has received less attention is the electroencephalogram or EEG. One EEG measure of brain function is the individual alpha peak frequency or iAPF.The iAPF is positively correlated with arousal, attention and speed of information processing. Higher iAPF is linked to faster spe........ Read more »

Can Eccentric Training Increase Muscle and Strength?
by Mansi Goel in Workout Trends
What is Eccentric Training?
Eccentric training – sounds very technical but it is anything but! If you have been doing any form of weight training, you have been doing eccentric training. The only thing is that you might not be focusing on it specifically.
When we are doing any sort of weight bearing exercise, two types of muscle contractions are involved – concentric and eccentric.
Concentric contractions shorten the muscle, for example, when your biceps shorten as you lift ........ Read more »
