High resistance-training frequency (5 days per week) significantly increases muscle thickness in the forearm flexors and vastus lateralis compared to training muscle groups once per week.
Practitioners should consider recommending higher training frequency for enhanced muscle growth.
StrongSupportsmedium confidence
TOTAL induced a significantly greater increase in MT of the forearm flexors and vastus lateralis (p < 0.05).
Why this rating
Based on the study design involving random assignment and controlled conditions.
