The Claim
In young untrained men, training volume (1 set vs. 3 sets) with high load (80% 1RM) does not significantly affect hypertrophy outcomes, although 3 sets demonstrated a non-significant trend toward greater muscle volume increase (80%-1: 3.2% vs. 80%-3: 7.2%, P=0.18).
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.
For young guys who don't usually exercise, doing one set or three sets of heavy lifting doesn't make a big difference in muscle growth, but three sets might have a small, not-proven benefit.
See the scientific wording
Training volume (1 vs. 3 sets) with high load (80% 1RM) does not significantly affect hypertrophy outcomes in young untrained men, though 3 sets showed a non-significant trend toward greater muscle volume increase (80%-1: 3.2% vs. 80%-3: 7.2%, P=0.18).
What the research says
1 studyStudy: Resistance exercise load does not determine training-mediated hypertrophic gains in young men.
The study looked at young men lifting weights with 1 set vs. 3 sets at high effort and found no big difference in muscle growth, just like the claim said, though 3 sets had a small non-significant advantage.
