The Claim
In untrained young men undergoing a resistance training program of 3 sets of 8 repetitions at 80% of one repetition maximum, performed 3 times per week for 6 weeks, greater acute muscle swelling—measured as an 8.3% increase in muscle thickness across 9 sites in the anterior thigh—immediately after the first training session is associated with greater muscle hypertrophy, defined as a 2.9% increase in muscle thickness after 6 weeks, with a correlation coefficient of ρ = 0.443.
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 a guy new to lifting weights gets a bigger muscle swell right after his first workout, he’s likely to gain more muscle over the next 6 weeks.

In untrained young men performing resistance training consisting of 3 sets of 8 repetitions at 80% of one repetition maximum, 3 times per week for 6 weeks, greater acute muscle swelling immediately after the first session—measured as an 8.3% increase in muscle thickness across 9 sites in the anterior thigh—is associated with greater muscle hypertrophy, defined as a 2.9% increase in muscle thickness after 6 weeks, with a correlation coefficient of ρ = 0.443.
What the research says
1 studyStudy: Relationship Between Muscle Swelling and Hypertrophy Induced by Resistance Training
The study found that men who had more muscle swelling right after their first workout tended to gain more muscle after 6 weeks, just like the claim says.
