The Claim
In female participants, both concentric and eccentric isokinetic exercise performed at long muscle lengths induce significant increases in delayed onset muscle soreness (DOMS) and muscle thickness in the elbow flexors, suggesting that both contraction types elicit inflammatory and edematous responses when executed under extended muscle length conditions.
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.
When women do certain types of arm exercises that involve stretching the muscle while contracting it, they tend to feel more soreness and their muscles get thicker — probably because of inflammation and fluid buildup.

Both concentric and eccentric isokinetic exercise at long muscle length produce significant increases in delayed onset muscle soreness (DOMS) and muscle thickness in the elbow flexors of female participants, indicating that both contraction types induce inflammatory and edematous responses when performed at extended muscle lengths.
What the research says
1 studyStudy: The effects of concentric and eccentric exercise performed at long muscle length on muscle damage
The study found that both types of arm exercises (squeezing and stretching) caused similar soreness and muscle swelling in women, especially when done with the arm extended, which supports the idea that both can cause muscle stress in that position.
