Energy balance

Subgroup analyses indicate trivial to small effects of resistance training tempo on muscle hypertrophy under specific conditions.

Practitioners should be aware that the effects of tempo may vary based on specific training conditions.

StrongQualifiesmedium confidence
Subgroup analyses of pairwise differences stratified by muscle action type (ECC or CON), body region (upper or lower body), and training to failure (yes or no) generally produced trivial to small effects.
