title: Exercise and Sarcopenia.
abstract: Sarcopenia is a major component of the frailty syndrome and is also a strong predictor of disability, morbidity, and mortality in older persons. Without any available pharmacological intervention to sarcopenia, non-pharmacological interventions are the only option to prevent these poor outcomes in sarcopenic patients. Among those interventions, physical activity with or without protein supplementation has demonstrated to be effective in improving muscle mass and function and in preventing disability and frailty in older persons. Additionally, to the beneficial effect of physical activity on metabolic and cardiovascular diseases, a regular exercise program (3 times/wk) that includes resistance and endurance exercise training would have a major positive effect on sarcopenic muscle through improving muscle mass, strength, and function. In this review, we looked at the effect of exercise on sarcopenic frail older persons from the biological aspects of the response of the muscle to exercise to some practical aspects of exercise prescription in this high-risk population. We conclude that, although challenging, older persons should be encouraged to participate in this type of programs, which would improve not only their function and independence but also their quality of life.
