Data are limited, however. In mice, ingesting exercise mimetics appeared to improve depressive-like behaviors, and the ...

Researchers identified a critical AMPK phosphorylation site that regulates mitochondria, muscle contraction, and sugar ...

Muscle loss (atrophy) due to inactivity is common after illness, injury, hospitalization or falls, and becomes increasingly ...

The mechanism for muscle stem cells repair could inspire therapeutics for muscle loss caused by injury, aging and weight-loss ...

Scientists found that muscles store a chemical record of past inactivity that gets significantly worse with age.

Researchers have identified a protein that’s critical to the development of skeletal muscle mass and strength and the tissue’s ability to metabolize glucose. They say their findings may lead to ...

Rapid weight loss can cause a greater loss of muscle mass than losing weight slowly. The popularity of newer weight-loss drugs that shed pounds quickly has raised concerns among researchers about how ...

Building muscle while in a calorie deficit requires high protein intake and strength training. Beginners often see faster muscle growth.

In work published in Nature Biotechnology, Rubin and his research group turned to 3D cell culture to take on the problem of generating sufficient satellite cells for regenerative therapies. 2 ...
