Hormonal
Both short (30 s) and long (150 s) rest intervals during low-load resistance training significantly increase growth hormone and insulin-like growth factor 1 immediately post-workout.
Practitioners can expect significant hormonal responses regardless of rest interval length in low-load training.
StrongSupportsmedium confidence
Both groups showed significant (p<0.05) increases in growth hormone and insulin-like growth factor 1 immediately post-workout.
Why this rating
Based on the controlled study design with statistical significance.
