Summary
Repeated-sprint training (RST) significantly enhances football players' sprint speed and ability. This training also promotes safer sprinting mechanics, reducing injury risk during fatigue.
Area of Science:
- Sports Science
- Biomechanics
- Exercise Physiology
Background:
- Repeated-sprint ability is crucial for football performance.
- Hamstring injuries are common in football, often linked to fatigue and sprinting.
Purpose of the Study:
- To investigate the effects of repeated-sprint training (RST) on repeated-sprint ability (RSA) and sprint kinematics in football players.
- To assess if RST can improve sprint performance and alter sprint mechanics under fatigue.
Main Methods:
- Fourteen semiprofessional male football players underwent 8 weeks of RST.
- Training involved repeated 30m sprints with short recovery periods.
- Sprint performance and high-frequency kinematic data were analyzed before and after training.
Main Results:
- Significant improvements were observed in 0-20m, 0-30m, and 20-30m sprint times.
- All RSA variables showed significant enhancement (P < .05).
- Post-RST, players exhibited reduced trunk flexion, altered kick-back, and less overstriding during fatigue.
Conclusions:
- RST effectively improves sprint performance and RSA in football players.
- RST may induce biomechanical adaptations leading to a safer sprint pattern, especially when fatigued.
- These findings suggest RST is a valuable training modality for football.
