Summary
Resisted sprint swim training did not improve 50-m freestyle performance more than nonresisted training in young swimmers over 10 weeks. Both methods yielded similar gains in sprint swim speed.
Area of Science:
- Sports Science
- Exercise Physiology
- Swimming Performance
Background:
- Optimizing sprint swim training is crucial for competitive age-group swimmers.
- Understanding the impact of resistance on sprint training efficacy is key for performance enhancement.
Purpose of the Study:
- To compare the effectiveness of resisted versus nonresisted sprint swim training.
- To evaluate the impact on 50-m freestyle competition time (Vmax50) in age-group swimmers.
Main Methods:
- Twenty-four swimmers (10.6-14.9 years) underwent 10 weeks of training (2x/week).
- Groups performed either resisted or nonresisted sprint swim training.
- Swim power, skeletal muscle mass, and maturity status were assessed.
Main Results:
- No significant group-by-time interaction was observed for measured variables.
- Vmax50 showed correlations with muscle mass and swim power, but relative changes were not significant.
- Maturity status was associated with initial swim power and performance.
Conclusions:
- Ten weeks of resisted sprint swim training did not offer superior benefits over nonresisted training for improving sprint swim performance.
- Neither training method demonstrated a significant advantage in enhancing sprint swim speed for this age group.
