Brief Summary

This study aims to examine the effects of a structured swimming training intervention on sport performance-related outcomes in 14- to 15-year-old federated swimmers from Club Huracanes. The study will use a single-group pre-post field design. Participants will complete baseline assessments before the intervention and post-intervention assessments after the final training week. The intervention will be integrated into the regular training process and will be supervised by the coaching and research team. Outcomes will include swimming performance-related measures and adherence to the intervention. Safety will be monitored throughout the study, and any adverse events or musculoskeletal complaints will be recorded. Written informed consent from parents or legal guardians and assent from the athletes will be required before participation.

Outcome Measures

Primary Outcomes (1)

• Change From Baseline in 15-m Swimming Start Time at Week 8

  The 15-m swimming start time will be measured in seconds from take-off from the starting block to crossing the 15-m mark. The assessment will be performed using standardized video-based timing procedures with visible 0-m and 15-m reference markers. Participants will complete three valid start attempts, separated by at least 3 minutes of recovery. The fastest valid attempt will be used for analysis. Lower values indicate better swimming start performance.

  Baseline and Week 8, within 48-96 hours after the final intervention session

Secondary Outcomes (3)

• Change From Baseline in Flight Distance During the Swimming Start at Week 8

  Baseline and Week 8, within 48-96 hours after the final intervention session

• Change From Baseline in Flight Time During the Swimming Start at Week 8

  Baseline and Week 8, within 48-96 hours after the final intervention session

• Change From Baseline in Vertical Jump Height at Week 8

  Baseline and Week 8, within 48-96 hours after the final intervention session

Study Arms (1)

Experimental: Structured Swimming Training Intervention

EXPERIMENTAL

Participants will complete a structured swimming training intervention integrated into their regular training process. The program will be supervised by qualified personnel and will include progressive swimming-related tasks designed to improve sport performance-related outcomes in 14- to 15-year-old federated swimmers.

Behavioral: Structured Swimming Training Intervention

Interventions

Structured Swimming Training Intervention BEHAVIORAL

The intervention will consist of a structured swimming training program delivered over 6 weeks, with 2 sessions per week. Sessions will be integrated into the athletes' regular training environment and will include age-appropriate, progressive swimming-related tasks. Training will be supervised, and the volume, intensity, recovery, and progression will follow the approved protocol. Pain, excessive fatigue, musculoskeletal discomfort, and adverse events will be monitored throughout the intervention.
