Neural
Maximal voluntary contraction (MVC) of the knee extensors was significantly greater in younger adults (256 ± 72 N·m) compared to older adults (137 ± 48 N·m), P < 0.001.
Younger adults demonstrate greater knee extensor strength, which may influence exercise programming for older adults.
StrongSupportsmedium confidence
MVC was significantly greater in young vs. older adults (Young: 256 ± 72 vs. Old: 137 ± 48 N·m, P < 0.001).
Why this rating
Based on the clear statistical significance and comparison of two distinct age groups.
