Effect of weight training on combating sarcopenia in older adults
By Pereira GHG, Filho MGDAC
Population aging leads to 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 older adults. In this context, this study aimed to address the effects of weight training (resistance training) on the prevention and treatment of sarcopenia, analyzing its physiological and functional benefits. To this end, applied research was conducted with a qualitative approach and a descriptive design, structured through a systematic literature review (RSL) with searches of scientific databases for articles published between 2008 and 2026. The results of the studies analyzed consistently demonstrate that regular resistance training promotes significant gains in strength, lean mass, muscle power, and balance, in addition to highlighting functional declines and reducing the risk of falls and fractures. It is concluded that weight training constitutes a highly effective and indispensable nonpharmacological strategy for combating sarcopenia, promoting longevity with functional independence, autonomy, and improved quality of life in the older population.
