The Claim

High-load resistance training (15.3 repetitions per session) and low-load resistance training (75.3 repetitions per session) to volitional failure produce similar hypertrophy outcomes in young male athletes, indicating volume equivalence for muscle growth.

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.

Quantitative

In plain English

Lifting heavy weights for fewer reps and lighter weights for more reps both build muscle about the same in young men when you push yourself to the max, showing that the total work done matters more than how heavy you lift.

See the scientific wording

Training volume (total repetitions) differs substantially between high-load (15.3 reps/session) and low-load (75.3 reps/session) resistance training to failure, yet produces similar hypertrophy outcomes in young male athletes, suggesting volume equivalence for muscle growth when training to volitional exhaustion.

What the research says

1 study
  1. Study: Impact of high versus low fixed loads and non-linear training loads on muscle hypertrophy, strength and force development

    The study shows that lifting heavy weights for fewer reps or light weights for more reps both build muscle equally well when you push to failure, just like the claim says.
