The Claim

Pre-exhaustion exercise consisting of 50 repetitions of isokinetic knee extensions does not significantly affect electromyographic fatigue threshold (EMGFT) in elite runners, indicating no change in neuromuscular fatigue following this protocol in highly trained endurance athletes.

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.

Cause and effect
1 study reviewed
In plain English

For top runners, doing 50 knee exercises in a special machine doesn't make their leg muscles get tired in a way that changes how quickly they fatigue, so it doesn't really affect their muscle tiredness after the workout.
