This comprehensive umbrella review analyzing 41 systematic reviews found that combined resistance exercise with protein supplementation (≥1.2 g/kg/day) produces superior muscle mass gains (standardized mean difference 0.22) and handgrip strength improvements (4.19 kg increase) compared to single interventions. Balance and multicomponent exercise programs reduced fall rates by 23-34%, while vitamin D supplementation (≥700 IU/day) provided an additional 13% fall reduction. This represents the first systematic convergence of two previously separate research domains—sarcopenia management and fall prevention—revealing their synergistic potential. The finding addresses a critical gap in geriatric care, where falls cause 32,000 deaths annually in older adults and sarcopenia affects up to 29% of community-dwelling seniors. The evidence quality was notably robust, with moderate-to-high certainty ratings and minimal study overlap. However, the review's reliance on existing systematic reviews rather than individual trials may mask important intervention nuances like optimal timing and progression protocols. This convergent approach suggests clinical practice should abandon isolated interventions in favor of integrated programs targeting both muscle preservation and fall prevention simultaneously.
