The Claim
Unfamiliar isokinetic exercise performed at long muscle lengths induces muscle damage in the elbow flexors of female participants, as evidenced by significant decreases in isometric peak torque and range of motion, increases in delayed onset muscle soreness and muscle thickness, and changes in ultrasonographic echo intensity, with these effects persisting up to 96 hours post-exercise.
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.
Doing a new type of strength exercise that stretches your biceps a lot can cause temporary muscle damage and soreness in women, and these effects can last up to four days.

Unfamiliar isokinetic exercise performed at long muscle lengths induces muscle damage in the elbow flexors of female participants, as evidenced by significant decreases in isometric peak torque and range of motion, increases in delayed onset muscle soreness and muscle thickness, and changes in ultrasonographic echo intensity, with effects persisting up to 96 hours post-exercise.
What the research says
1 studyStudy: The effects of concentric and eccentric exercise performed at long muscle length on muscle damage
The study looked at a specific arm exercise done at long muscle lengths in women, and found it caused muscle damage that lasted up to four days, just like the claim says.
