Abstract:

Aging affects the response to short-term immobilization and the regenerative capacity of human skeletal muscle. This paper describes research showing that immobilized/retrained old individuals appear to be more affected with respect to neural function while young individuals are more affected in terms of muscle size. These data indicate that aging is accompanied by an impaired ability to recover from disuse muscle atrophy; consequently, old individuals may need longer time to recover from periods of disuse than young individuals.
