Despite their reputation for causing muscle injury, a new study suggests statins won't worsen the toll that sustained, moderately intensive exercise already takes on patients' muscles.

The researchers also investigated how exercise alone affected gene expression in muscle fibers from both mice and humans. The mice were 22 months old, which is equivalent to a human age of around ...

Regulatory T cells require IL6 receptor alpha signaling to control skeletal muscle function and regeneration. Cell Metabolism, 2023; DOI: 10.1016/j.cmet.2023.08.010 ...

To determine the effects of aerobic exercise on muscle mass overall, as well as muscle in specific areas of the body, researchers measured muscle and fat tissue in 238 men and women, then asked ...

In a recent interview with Wolf, Kevin Murach, Ph.D., an assistant professor at the University of Arkansas specializing in exercise science and muscle physiology, explained this concept further.
