Adherence
High-intensity resistance exercise training (HIRT) significantly increases muscle cross-sectional area and knee extensor torque in elderly populations, effectively counteracting age-related sarcopenia.
Start with resistance training twice a week for 30 minutes. You can use machines, body weight, or elastic bands. This is safe for frail elderly people and significantly boosts muscle strength and size, helping prevent falls and maintain independence.
GoodSupportsHIGH confidence
Increases of 11.4% in midthigh muscle CSA and greater than 100% in knee extensor torque were reported by Frontera et al. in a cohort of elderly men who had undergone 12 weeks of high-intensity resistance exercise training [90], with similar changes observed in a subsequent study in women by Charette and colleagues [91].
Why this rating
Based on multiple cited studies (Frontera, Charette, Fiatarone) showing consistent positive outcomes, though specific statistical p-values for the aggregate claim are not provided in the text snippet.
