The Claim
In resistance-trained men, high-volume resistance training that elicits greater acute cortisol and growth hormone responses does not result in greater muscle hypertrophy or strength gains over an 8-week period compared to high-intensity resistance training, despite the observed differences in hormonal responses.
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.
If you're a guy who lifts weights, doing more reps with lighter weights (which spikes your hormones more) doesn't build more muscle or strength over 8 weeks than lifting heavier weights with fewer reps—even though the hormone changes look different.
See the scientific wording
In resistance-trained men, greater acute cortisol and growth hormone responses to high-volume resistance training do not lead to greater muscle hypertrophy or strength gains over 8 weeks compared to high-intensity training, despite the hormonal differences.
What the research says
1 studyEven though high-volume workouts caused bigger spikes in hormones like cortisol and growth hormone, those men didn’t gain more muscle or strength than those doing heavier, lower-rep sets. The study shows hormone spikes don’t necessarily mean better gains.
