The Claim
Resistance exercise training performed to volitional fatigue at either 30% or 80% of one-repetition maximum for 10 weeks increases peak torque and type I muscle fiber cross-sectional area similarly in previously untrained young men, demonstrating that muscle strength and hypertrophy adaptations are load-independent when fatigue is achieved.
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 weights until you're tired, whether with light or heavy weights, makes your muscles bigger and stronger in the same way for beginners.
See the scientific wording
Resistance exercise training performed to volitional fatigue at either 30% or 80% of one-repetition maximum (1RM) for 10 weeks increases peak torque and type I muscle fiber cross-sectional area similarly in previously untrained young men, demonstrating that muscle strength and hypertrophy adaptations are load-independent when fatigue is achieved.
What the research says
1 studyStudy: Resistance Exercise-induced Changes in Muscle Metabolism are Load-dependent.
The study found that lifting weights until tired, whether with heavy or light weights, made muscles bigger and stronger in the same way, which matches the claim.
