Summary
Mean propulsive velocity (MPV) did not show significant neuromuscular fatigue in traditional strength training for Paralympic powerlifters. However, eccentric training caused performance loss and reduced MPV, suggesting MPV may better control training volume.
Area of Science:
- Sports Science
- Biomechanics
- Paralympic Sports
Background:
- Mean propulsive velocity (MPV) is linked to neuromuscular fatigue.
- Its application in Paralympic powerlifting (PP) strength training requires investigation.
Purpose of the Study:
- To evaluate MPV changes under traditional (TRAD) and eccentric (ECC) training methods in PP athletes.
- To determine MPV's effectiveness as an indicator of neuromuscular fatigue in PP.
Main Methods:
- Eleven PP athletes underwent TRAD and ECC interventions.
- MPV was assessed pre, during, and post-intervention at specific loads (80% 1RM for TRAD; 110%-80% 1RM for ECC).
Main Results:
- TRAD training showed no significant neuromuscular fatigue or MPV decline.
- ECC training resulted in significant performance loss (~12%) and reduced MPV post-intervention.
- MPV did not significantly decline during the ECC intervention itself.
Conclusions:
- MPV appears ineffective for indicating neuromuscular fatigue in this PP training context.
- MPV may serve as a more suitable measure for controlling training volume in PP.
