Caloric Restriction Decreases Muscle Cell Death with Age

Sarcopenia: the role of apoptosis and modulation by caloric restriction. Dirks Naylor AJ, Leeuwenburgh C. Exerc Sport Sci Rev. 2008 Jan;36(1):19-24. Abstract The mechanisms of sarcopenia have been slowly unraveled and likely involve activation of apoptosis. It is hypothesized that caloric restriction may, in part, attenuate sarcopenia by affecting apoptotic signaling. The signaling pathways responsible … Read more
