Clinical trials: Atrophy, Disuse
Muscle Atrophy, Disuse Atrophy (Muscle) of Lower Leg
The Regulation of Human Skeletal Muscle Mass by Contractile Perturbation
It is well known that periods of weight training lead to increases in skeletal muscle size and strength. In contrast, periods of inactivity such as bed rest or immobilization result in losses of skeletal muscle size and strength.
