Brief summary

This randomized controlled trial will compare the effects of dolphin kick streamline training versus flutter kick training on core stability and sprint performance in competitive swimmers. Both groups will receive the same land-based core conditioning program in addition to their assigned aquatic kicking training. Core stability and sprint performance will be assessed at baseline, Week 4, and Week 8 to determine whether either training approach produces greater improvements in competitive swimming performance.

Detailed description

This randomized controlled trial will evaluate and compare the effects of dolphin kick streamline training and flutter kick training on core stability and sprint performance in competitive swimmers. Participants will be randomly allocated to one of the two aquatic training groups. Both groups will receive an identical land-based core conditioning program to control for general core-strength adaptations. The intervention will be conducted over eight weeks, with outcome assessments performed at baseline (Week 0), Week 4, and Week 8. The study aims to determine whether dolphin kick streamline training or flutter kick training produces greater improvements in core stability and short-distance sprint swimming performance.

Interventions

BEHAVIORALDolphin Kick Streamline Training

An 8-week progressive dolphin kick streamline training program for healthy male competitive swimmers aged 16-30 years with a minimum of 2 years of competitive swimming experience. Training frequency progresses from 3 sessions per week during Weeks 1-2 to 5 sessions per week during Weeks 6-8, with session duration progressively increasing. The training progresses from basic body undulation and flutter-to-dolphin transition to kickboard and underwater dolphin kick sets, race-pace butterfly training, sprint intervals, technique refinement, and race simulation. Participants also receive an identical land-based core conditioning program consisting of forearm plank, side plank, bird-dog, and dead bug exercises throughout the 8-week study period.

BEHAVIORALFlutter Kick Training

An 8-week progressive flutter kick training program for healthy male competitive swimmers aged 16-30 years with a minimum of 2 years of competitive swimming experience. Training is conducted 2 times per week. Weeks 1-2 consist of low-intensity training, Weeks 3-4 low-moderate intensity, Weeks 5-6 moderate intensity, Week 7 moderate-high intensity, and Week 8 high-intensity training. Exercise duration, rest intervals, and resistance are progressively modified, with light medicine-ball resistance introduced during Weeks 7-8. Participants also receive an identical land-based core conditioning program consisting of forearm plank, side plank, bird-dog, and dead bug exercises throughout the 8-week study period.
