A study led by researchers at the University of California, Berkeley, has identified critical biochemical pathways linked to the aging of human muscle. By manipulating these pathways, the researchers were able to turn back the clock on old human muscle, restoring its ability to repair and rebuild itself.

Many active young women use oral contraceptives (OC) yet its effect on their body composition and exercise performance has not been thoroughly studied.

Octogenarian women were unable to increase muscle mass after a 3-month weight lifting program targeted at strengthening the thigh muscle, according to a new study from the Journal of Applied Physiology.

Young female athletes could have yet another reason to grab a glass of vitamin D-rich milk.

A Michigan State University researcher is studying whether the most popular class of cholesterol-lowering drugs may cause muscle problems in users.

A study has found that people who facially express pain in a more intense way are not exaggerating if their perception of a painful stimulation is controlled. The study conducted by Miriam Kunz is published in the November issue of Pain.

Women's muscles may require longer, more intensive rehabilitation after bed rest and cast immobilization, as reported today by the Institute for Neuromusculoskeletal Research at the Ohio University College of Osteopathic Medicine (OU-COM).

Findings may have implications for how women are treated for fractures; more rehabilitation may be required to recover from immobilization or bed rest

While steroids can help build the bulky muscles that lend athletes and body builders power and speed, there hadn't been a drug capable of building the endurance needed to run a marathon or to ride a bike through the Alps. Now, there just might be, suggests a new study in mice reported in the journal Cell, a Cell Press publication.

A new CU-Boulder study of a space-age, low-gravity training machine led by Associate Professor Rodger Kram, (pictured here) shows the machine significantly reduced impacts on muscles and joints of study subjects.

Using an unusual microscope with a tip the size of a needle, Stanford researchers are now able to look at tiny fibers of working muscles in live humans, with minimum discomfort to the patient—a development patients are sure to welcome.

Recipe to recover more quickly from exercise: Finish workout, eat pasta, and wash down with five or six cups of strong coffee.
