Sarcopenia is a geriatric disease characterized by a marked loss of muscle mass and strength. This has led to it being recognized for the role it plays in elderly morbidity and mortality. It is a multifactorial disease with many mechanisms to how it comes about. So far, increasing physical activity has proven to be the best therapeutic agent. Exercise is capable of increasing flow of nutrition to muscle, reversing mitochondrial damage, increasing muscle mass, and strength. Furthermore, resistance training has been shown to be superior to aerobic training when it comes to increasing muscle mass and strength. Additionally, exercise plays a role in both prevention and treatment of sarcopenia, especially in a background of adequate nutrition. With increasing age, the effect of exercise is also subjected to issues such as anabolic resistance that can make increasing muscle mass and strength more challenging. However, physical activity and exercise remain the most important components of improving muscular strength.
