Resumo: The main purpose of this study was to follow-up the intra- and inter-individual variability of young swimmers' performance and determinant factors over two competitive seasons. Thirty young swimmers (14 boys: 12.33±0.65 years-old; 16 girls: 11.15±0.55 years-old) were followed-up throughout two consecutive seasons (seven evaluation moments). Performance (100m freestyle), anthropometric, kinematic, hydrodynamic and efficiency features were evaluated. A gender and skill-level effect was observed. Boys improved in a higher amount (%) comparing to girls. Overall, swimmers in skill-level 2 (both genders) presented a higher intra-individual variability. Performance and anthropometrics showed a significant inter-individual variability in most moments, but hydrodynamics, kinematics and efficiency did not. Within each skill-level hydrodynamics, kinematics and efficiency were the variables that showed a high inter-individual variability. As a gender and skill-level effect was noticed in an age-group of young swimmers, coaches and practitioners should put the focus in specific and customized training plans for each skill-level of swimmers.

O objetivo principal do estudo foi acompanhar a variabilidade intra- e inter-individual da performance e dos seus fatores determinantes de nadadores jovens durante duas temporadas competitivas. Trinta nadadores jovens (14 nadadores: 12.33±0.65 anos; 16 nadadoras: 11.15±0.55 anos) foram avaliados ao longo das duas épocas (7 momentos de avaliação). Foi avaliada a performance (100m livres), e variáveis antropométricas, cinemáticas, hidrodinâmicas e de eficiência. Foi observado um efeito do sexo e do nível competitivo. Os nadadores melhoraram em maior quantidade (%) do que as nadadoras. Os nadadores no nível competitivo 2 (ambos os sexos) apresentaram uma intra-variabilidade superior. A performance e as variáveis antropométricas apresentaram uma inter-variabilidade significativa na maior parte dos momentos de avaliação, ao contrário das variáveis hidrodinâmicas, cinemáticas e de eficiência. Dentro de cada nível competitivo as variáveis hidrodinâmicas, cinemáticas e de eficiência foram as que apresentaram uma variabilidade inter-individual superior. Como foi verificado um efeito do sexo e do nível competitivo, treinadores e praticantes devem colocar o foco em treinos específicos e personalizados para cada grupo de nadadores de acordo com o nível competitivo.Análisis longitudinal de la variabilidade intra- y inter-individual del rendimiento y sus determinantes en nadadores jóvenes.” El objetivo principal del estudio fue el seguimiento de la variabilidad intra- e inter-individual del rendimiento y sus factores determinantes de nadadores jóvenes en dos temporadas competitivas. Treinta nadadores jóvenes (14 niños: 12.33±0.65 años; 16 niñas: 11.15±0.55 años) fueron seguidos a lo largo de dos temporadas competitivas (7 momentos de evaluación). Se evaluó el rendimiento (100m estilo libre), e características antropométricas, cinemáticas, hidrodinámicas e la eficiencia. Se observó un efecto del sexo e del nivel de habilidad. Los niños mejoraron en una cantidad superior (%) en comparación con las niñas. En general, los nadadores de nivel de habilidad 2 (los dos sexos) presentaron una mayor variabilidad intra-individual. El rendimiento y la antropometría mostraron una variabilidad inter-individual significativa en la mayoría de los momentos, lo mismo no ocurrió con la hidrodinámica, la cinemática y la eficiencia. Dentro de cada nivel de habilidad, la hidrodinámica, la cinemática y la eficiencia fueron las variables que mostraron una alta variabilidad inter-individual. Como se ha observado un efecto de sexo e nivel de habilidad, entrenadores y practicantes deben poner el foco en los planes de formación específicos y personalizados para cada nivel de habilidad de los nadadoresBiblioteca Digital do IPBMorais, J.E.Costa, M.J.Forte, PedroSilva, A.J.Marinho, D.A.Barbosa, Tiago M.2015-07-06T13:05:26Z20142014-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10198/11936engMorais, J.E.; Costa, M.J.; Forte, Pedro Miguel Gomes; Silva, A.J.; Marinho, D.A.; Barbosa, Tiago M.
