Abstract

Frailty and sarcopenia are geriatric syndromes
highly prevalent, complex, and hard to diagnose and treat.
The literature still lacks a consensus on which resistance
training program is better for older people, especially
when considering frailty status and sarcopenia. We
aimed to evaluate the effectiveness of a progressive
resistance training program on muscle mass and frailty
status in older sarcopenic women. This study included
18 community-dwelling sarcopenic women aged 65 or older
enrolled in the progressive resistance training program.
The intervention was based on 75% of each subject’s
maximum repetition test (3 times/week, for 12 weeks).
Before the intervention, 16.7% were frail, and 61.1% were
pre-frail; after the intervention, 5.6% were frail, and 50%
were pre-frail. The result shows that the intervention reduced
frailty status and increased muscle mass (p=0.01). Hence,
after the intervention, we observed both a decrease in frailty
and a positive change in function, since the percentage of
robust women increased twice (p=0.01). We conclude that
the progressive resistance training program might be the
best strategy to prevent frailty and sarcopenia. Therefore,
we suggest using weight resistance training in daily clinical
practice to improve muscle mass and decrease frailty status
in sarcopenic women.
