简要总结
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.
详细描述
This is a field-based, single-group pre-post interventional study conducted with 14- to 15-year-old federated swimmers from Club Huracanes. The intervention will be implemented as part of the athletes' regular training environment and will be designed according to their age, developmental stage, training background, and competitive level.
Participants will undergo baseline testing before the beginning of the intervention and post-intervention testing after completion of the training program. The training intervention will be supervised by qualified personnel and will include progressive swimming-related training tasks aimed at improving sport performance-related outcomes. The training load will be controlled to avoid demands that substantially exceed the athletes' usual practice. Each session will include an appropriate warm-up, supervised execution of the planned tasks, adequate recovery periods, and monitoring for pain, excessive fatigue, discomfort, or any sign of risk.
Because the study involves minors and a sport-specific sample, ethical safeguards will include written informed consent from parents or legal guardians, assent from the athletes, confidentiality of personal information, and the right to withdraw voluntarily at any time without consequences for the athlete's participation in the club. Any adverse event will be recorded and managed according to the procedures available at the training venue.

研究组 & 干预措施
Experimental: Structured Swimming Training Intervention
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.
干预措施: Structured Swimming Training Intervention (Behavioral)
结局指标
主要结局
Change From Baseline in 15-m Swimming Start Time at Week 8
时间窗: Baseline and Week 8, within 48-96 hours after the final intervention session
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.
次要结局
- 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)
