The Claim
High-load resistance training (80% 1RM) performed to failure three times per week for six weeks results in significantly greater increases in maximal strength (1RM and MVIC) compared to low-load training (30% 1RM) in untrained young men, with improvements of 27.7% versus 9.5% for 1RM and 28.0% versus 13.4% for MVIC, despite similar muscle hypertrophy (~6% increase in both groups).
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 heavy weights three times a week for six weeks makes untrained young men much stronger than lifting light weights, even though both groups gain about the same amount of muscle size.

What the research says
1 studyStudy: Greater Neural Adaptations following High- vs. Low-Load Resistance Training
The study looked at the same type of weight training as the claim and found that lifting heavier weights made people much stronger than lifting lighter weights, even though both groups got similarly bigger muscles, which matches what the claim says.
