(English) Episode 109-Boost Your "Go-Go" Power - Why Speed Matters More Than Strength for Aging Well

This research article presents a systematic review and meta-analysis evaluating the effectiveness of power training (PT) compared to traditional strength training in enhancing physical function among older adults. The authors synthesized data from 20 randomized clinical trials, involving 566 community-living individuals, to determine if lifting weights quickly offered superior benefits to controlled lifting and lowering. The primary outcomes examined were physical function and self-reported physical function, with secondary outcomes including strength, muscle mass, and balance. While the study found a modest improvement in physical function and self-reported function with power training, the evidence certainty was low, indicating a need for further robust research with larger sample sizes to draw definitive conclusions.(Balachandran AT, Steele J, Angielczyk D, Belio M, Schoenfeld BJ, Quiles N, et al.
