The Claim
Multi-joint and single-joint resistance exercises result in comparable increases in elbow flexor muscle strength in untrained young men following a 10-week training period, with no statistically significant difference observed between the two exercise modalities.
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 haven't exercised before do either multi-joint exercises (like pull-ups) or single-joint exercises (like bicep curls) for 10 weeks, their arm strength increases by about the same amount - neither type of exercise is clearly better than the other.
See the scientific wording
Multi-joint and single-joint resistance exercises produce similar increases in elbow flexor muscle strength in untrained young men after 10 weeks of training, with no statistically significant difference between exercise types
What the research says
1 studyStudy: Single vs. Multi-Joint Resistance Exercises: Effects on Muscle Strength and Hypertrophy
The study compared two types of arm exercises - multi-joint (like lat pulldowns) and single-joint (like bicep curls) - done for 10 weeks by men who had never weight trained before. Both groups got stronger with no real difference between them, exactly matching what the claim says.
