简要总结
In the present study, the effects of 5 days of lower limb immobilization with or without twice-daily protein supplementation on muscle mass and muscle fiber characteristics will be determined. A young group will be included to compare the changes in muscle mass and muscle fiber characteristics between young and old men.
