The Claim

In novice adults performing leg press drop set resistance training to muscle failure, neuromuscular fatigue progressively develops across repetitions and sets, as indicated by increased normalized electromyographic activity (nEMG) in most leg muscles (excluding vastus medialis and semitendinosus), decreased median power frequency (MPF) in all muscles except biceps femoris, and increased wavelet index ratio (WIRW51) in all muscles except gluteus maximus, reflecting altered muscle activation patterns and fatigue-related spectral shifts during high-volume resistance exercise.

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.

How it works
1 study reviewed
In plain English

When beginners do intense leg press workouts to the point of exhaustion, their muscles get increasingly tired, and this shows up as changes in muscle activity signals — some muscles work harder, others change how they fire, and these shifts tell us fatigue is building up.

What the research says

1 study

  1. Study: Neuromuscular Fatigue During Heavy Resistance Drop Set Training to Failure.

    The study looked at how muscles get tired during a specific leg workout, and found that the electrical activity in the muscles changed in ways that show increasing fatigue, just like the claim says.
