    Resumen Objetivo: verificar si tres semanas de interrupción del entrenamiento afectan el rendimiento y la cinemática de 200 m en nado crol en nadadores de 12 años y menores mientras se controlan los cambios antropométricos.

    Método: Dieciséis nadadores de grupos de edad (11 niñas y 5 niños, edad: 10,2 ± 1,2 años) realizaron una prueba de 200 m nado crol (contrarreloj) pre y post tres semanas (fuera de temporada), donde se obtuvieron el rendimiento, variables cinemáticas y antropométricas.

    Resultados: La altura aumentó ~ 1.0 cm (IC: 0.70 a 1.3 cm; p <0.001; d = 0.07). Se observaron cambios triviales para el rendimiento (diferencia media: 3,3 s IC: -6,7 a 13,9; p = 0,69; d = 0,08) y las variables cinemáticas (p de 0,69 a 0,84; d <0,001 para todas). Se observaron altas correlaciones intraclase (CCI: 0,69 a 0,84; p <0,001) para todas las variables después de tres semanas, lo que indica estabilidad en el tiempo.

    Conclusión: Tres semanas fuera de temporada no afecta el rendimiento en 200 m nado crol ni las variables cinemáticas en nadadores de 12 años y menores.

    Palabras clave: natación, desentrenamiento, rendimiento, cinemática, antropometría.

    Abstract Objective: to verify if three-weeks of training cessation affects 200 m front crawl performance and kinematics in 12 years old and under age-group swimmers controlling for anthropometric changes.

    Method: Sixteen age-group swimmers (11 girls and 5 boys, age: 10.2 ± 1.2 y) performed a 200 m front crawl test (T200) (time trial) PRE- and POST three-weeks (off-season), where performance, kinematics and anthropometrics variables were obtained.

    Results: Height increased ~1.0 cm (CI: 0.70 to 1.3 cm; p < 0.001; d = 0.07). Trivial changes were observed for performance (mean diff: 3.3 s CI: -6.7 to 13.9; p = 0.69; d = 0.08) and kinematical variables (p from 0.69 to 0.84; d < 0.001 for all). High intraclass correlations (ICC: 0.69 to 0.84; p < 0.001) were observed for all variables after three-weeks, indicating stability over time.

    Conclusion: Three-weeks off-season does not impair swimming T200 performance and kinematic variables in 12 years old and under age-group swimmers.
