Understanding Sarcopenia Development: A Role for Healthy Behaviors.

For decades the biomedical community has documented the accelerated loss of muscle mass that occurs with advancing aging, termed sarcopenia. The timely review article ("Attenuation of Adverse Effects of Aging on Skeletal Muscle by Regular Exercise and Nutritional Support") by Arthur Leon presents our current state of knowledge on the biological processes responsible for age-induced loss of muscle mass and function. This loss of skeletal muscle has critical health implications as it can negatively affect morbidity and mortality. A significant theme throughout the review is that a lifelong commitment to regular physical activity and good dietary habits is extremely important to combat age related reductions in muscle mass and function. However, multi-targeted therapeutic approaches, in conjunction with nutrition and exercise, may be beneficial to prevent or treat sarcopenia. Additionally, while significant progress has been made in our understanding of the molecular and biochemical contributors to sarcopenia, further research using well-controlled clinical trials are needed to determine the long-term benefit of exercise and nutrition on aging skeletal muscle.
