Neural
Relative quadriceps muscle EMG activity was significantly higher in older adults compared to younger adults across all exercise tasks (P < 0.01).
Older adults may require different training approaches to optimize muscle activation.
StrongSupportsmedium confidence
EMG activity during all exercise tasks was significantly higher in older vs. younger adults when expressed relative to maximal EMG achieved during MVC (P < 0.01, for all).
Why this rating
The claim is supported by statistical significance across multiple tasks.
