ABSTRACT

Physical exercise with resistance training is considered the most effective treatment for sarcopenia. Resistance changes metabolic signaling to effectively maintain muscle mass, but only 15% of United States adults achieve recommended levels of physical activity. Concordantly sarcopenia is common and clinically manifest in most adults over 75 years of age. Sarcopenia is a significant contributor to orthopedic conditions among the elderly, particularly hip fractures. Once deconditioning and sarcopenia manifest the requisite resistance exercise is difficult to achieve and the metabolic milieu is unlikely to be conducive to muscle reacquisition. Therefore prevention and early identification for risk modification are important for orthopedic outcomes on population and patient levels.
