Supervised resistance exercise training significantly increases muscle strength and functional capacity in frail elderly individuals, demonstrating that physical frailty is not an irreversible consequence of aging.
If you or a loved one is experiencing frailty or loss of strength, do not accept it as inevitable. Supervised resistance training (approx. 45 mins, 3x/week) can significantly restore muscle strength and mobility, even in nursing home residents in their 80s. The key is consistency and supervision to overcome the high dropout rates typical of self-directed exercise.
GoodSupportsHIGH confidence
Supervised resistance exercise training (for 45 min three times per week for 10 weeks) doubled muscle strength and significantly increased gait velocity and stair-climbing power. This demonstrates that frailty in the elderly is not an irreversible effect of aging and disease but can be reduced and perhaps even prevented.
