The Claim
Low-load resistance training performed to volitional fatigue results in significantly smaller improvements in one-repetition maximum strength (8.6% increase) and maximal elbow extension strength (6.5% increase) compared to high-load resistance training (21.0% and 13.9% increases respectively), while producing similar levels of muscle hypertrophy.
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.
Lifting lighter weights until you can't lift anymore doesn't make you as strong as lifting heavier weights, even though both make your muscles grow about the same size.

Low-load resistance training to volitional fatigue produces significantly smaller improvements in one-repetition maximum strength (8.6% increase) and maximal elbow extension strength (6.5% increase) compared to high-load resistance training (21.0% and 13.9% increases respectively), despite producing similar muscle hypertrophy.
What the research says
1 studyThe study found that lifting lighter weights until tired gives smaller strength gains than lifting heavier weights, even though muscles grow about the same size, which is exactly what the claim says.
