The Claim
Higher velocity loss thresholds (>25%) during resistance training do not produce greater muscle hypertrophy than moderate velocity loss thresholds (20–25%), as evidenced by a trivial effect size of 0.08 (95% CI −0.16 to 0.32), indicating that increasing effort toward failure via velocity loss does not consistently enhance 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.
Pushing yourself harder during weightlifting by stopping later (more than 25% slower than your fastest rep) doesn’t help you build more muscle than stopping a bit earlier (20–25% slower)—the difference is so tiny it doesn’t really matter.
See the scientific wording
Higher velocity loss thresholds (>25%) do not produce greater muscle hypertrophy than moderate thresholds (20–25%) during resistance training, with a trivial effect size of 0.08 (95% CI −0.16 to 0.32), indicating that pushing closer to failure via velocity loss does not consistently enhance muscle growth.
What the research says
1 studyThe study found that lifting weights until you're almost completely exhausted (more than 25% speed loss) doesn't make your muscles grow any better than stopping just before total exhaustion (20–25% speed loss). So, going harder doesn't help you get bigger muscles.
