The Claim
In untrained young adult males, a 10-week resistance training program consisting of single-joint elbow flexion exercises performed twice weekly results in statistically significant increases in elbow flexor muscle strength of approximately 11.9%.
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 young men who have never weight trained before do bicep curls twice a week for 10 weeks, their arm strength increases by about 12% on average.
See the scientific wording
Untrained young men performing single-joint exercises (bicep curls) experience significant muscle strength gains of approximately 11.9% in elbow flexors after 10 weeks of resistance training twice weekly
What the research says
1 studyStudy: Single vs. Multi-Joint Resistance Exercises: Effects on Muscle Strength and Hypertrophy
The study tested exactly what the claim says - untrained young men doing bicep curls twice a week for 10 weeks - and found they gained about 11.9% strength in their elbow flexors, which is exactly what the claim claims.
