In the largest study to date of the Arthritis Foundation's Tai Chi program, participants showed improvement in pain, fatigue, stiffness and sense of well-being. Their ability to reach while maintaining balance also improved, said Leigh Callahan, PhD, the study's lead author, associate professor in the University of North Carolina at Chapel Hill School of Medicine and a member of UNC's Thurston Arthritis Research Center.
Researchers at Vanderbilt University have "engineered" a mouse that can run on a treadmill twice as long as a normal mouse by increasing its supply of acetylcholine, the neurotransmitter essential for muscle contraction. The finding, reported this month in the journal Neuroscience, could lead to new treatments for neuromuscular disorders
After taking a small dose of inorganic nitrate for three days, healthy people consume less oxygen while riding an exercise bike. A new study in the February issue of Cell Metabolism traces that improved performance to increased efficiency of the mitochondria that power our cells.
New research at the University of Essex could help athletes train to their maximum potential without putting undue pressure on their muscles. A special wireless device -- called the iSense -- has been devised which is capable of predicting and detecting the status of muscles during training and can be adapted to any sport.
An Indiana University study found that strengthening inspiratory muscles by performing daily breathing exercises for six weeks significantly reduced the amount of oxygen these same breathing muscles required during exercise, possibly making more oxygen available for other muscles.
Scientists investigating natural ways to enhance athletic performance have found that bovine colostrum can massively reduce gut permeability -- otherwise known as 'leaky gut syndrome.' Their findings, published in the March issue of the American Journal of Physiology-Gastrointestinal and Liver Physiology, could have positive implications not just for athletes but also for sufferers of heatstroke.
A new research report appearing online in the FASEB Journal shows that what someone drinks after exercise plays a critical role in maximizing the effects of exercise. Specifically, the report shows that protein drinks after aerobic activity increases the training effect after six weeks, when compared to carbohydrate drinks. Additionally, this study suggests that this effect can be seen using as little as 20 grams of protein.
In search of a way to prevent the muscle wasting that comes with illness and aging, researchers have landed a natural compound that might just do the trick. The findings reported in the June issue of Cell Metabolism, a Cell Press publication, identify a component of apple peels as a promising new drug candidate for the widespread and debilitating condition that affects nearly everyone at one time or another.
Dieting postmenopausal women who want to avoid losing muscle as they lose fat should pay attention to a new University of Illinois study. Adding protein throughout the day not only holds hunger pangs at bay so that dieters lose more weight, it keeps body composition -- the amount of fat relative to muscle -- in better proportion.
Physical activity requires strong, healthy muscles. Fortunately, when people exercise on a regular basis, their muscles experience a continuous cycle of muscle breakdown (during exercise) and compensatory remodeling and growth (especially with weightlifting). Athletes have long experimented with methods to augment these physiologic responses to enhance muscle growth. One such ergogenic aid that has gained recent popularity is...
