EFFECT OF WEIGHT TRAINING IN COMBATING SARCOPENIA IN THE ELDERLY

Abstract

Global population aging brings an increase in degenerative clinical conditions, notably sarcopenia—a syndrome characterized by the progressive loss of muscle mass, strength, and function that compromises the autonomy and quality of life of the elderly. Therefore, this study aimed to address the effects of weight training (resistance training) in the prevention and treatment of sarcopenia, analyzing its physiological and functional benefits. To this end, an applied research study was developed with a qualitative approach and descriptive character, structured through a Systematic Literature Review (SLR) with searches in scientific databases for articles published between 2008 and 2026. The results of the analyzed studies consistently demonstrate that regular resistance training promotes significant gains in strength, lean mass, muscular power, and balance, in addition to mitigating functional declines and reducing the risk of falls and fractures. It is concluded that weight training constitutes a highly effective and indispensable non-pharmacological strategy in combating sarcopenia, promoting longevity with functional independence, autonomy, and an improved quality of life for the elderly population.
