The Claim
When resistance training volume load is equalized, self-selected repetition duration and controlled repetition duration protocols produce statistically indistinguishable gains in muscle strength and hypertrophy in untrained men.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In untrained men, lifting weights with either a self-chosen pace or a fixed pace results in the same amount of muscle strength and size gain, as long as the total weight lifted is the same.
See the scientific wording
When resistance training volume load is equalized between self-selected and controlled repetition duration protocols in untrained men, muscle strength and hypertrophy gains remain statistically indistinguishable, indicating that volume load is a more critical determinant of adaptation than repetition tempo.
When the same total weight is lifted, whether slowly or quickly, the muscles experience enough force and fatigue to trigger protein building and stronger nerve signals to the muscles, leading to more strength and size.
What the research says
1 studyWhen people lift weights at their own pace or a set pace, but lift the same total amount of weight, they gain the same amount of strength and muscle size. The speed doesn’t matter as much as how much weight you lift overall.
