Neural
Low-load resistance exercise (50% of 1RM) results in greater total integrated EMG muscle activation compared to high-load resistance exercise (80% of 1RM).
Incorporating low-load exercises may enhance overall muscle activation in training programs.

iEMG total favoring LOW (p = 0.001) across all muscle groups in both conditions.
Why this rating
Based on the study design involving resistance-trained men and EMG measurements.
