Plain-language 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.
