ARTIGO ORIGINAL | ORIGINAL ARTICLE RESUMOO Este estudo teve como objetivo avaliar o tempo de reação simples (TRS) e de escolha (TRE) e o desempenho no nado crawl em diferentes níveis de aprendizagem. Fizeram parte deste estudo 26 sujeitos com idade média de 12.15 anos divididos em dois grupos: iniciantes (G1) e avançados (G2). Avaliou-se o tempo de reação (TR) por meio de um software e o nado crawl com o Teste de Desempenho Motor do Nado Crawl. Os resultados demonstraram diferença no TRS com média de G1 = .341s e G2 = .271s (t = ˗ 3.670; p = .001; TE= 0.60) e no TRE com média de G1= .651s e G2= . 492s (t = ˗ 4.016; p = .001; TE= 0.63), indicando que no estágio avançado os aprendizes possuem melhores tempos de resposta.Uma correlação moderada encontrou-se entre G1 (iniciante) e TRE (avançado) (r = -0.560; p = 0.046), e G2 (avançado) e TRS (avançado) (r = -0.685; p = 0.010). Conclui-se que o TR é importante para o sucesso na performance do nado crawl uma vez que seu aprimoramento resulta em menores gastos de tempo em indivíduos em estágio avançado.Palavras-chave: Tempo de reação, Destreza Motora, Natação, Aprendizagem. ABSTRACTThe aim of this study was to evaluate the simple reaction time (SRT), the choice reaction time (CRT) and the performance of front crawl swimming at different learning levels. This study had 26 participants of both genders with a mean age of 12.15 years, divided in 2 groups: beginners (G1) and advanced (G2). Reaction time (RT) was assessed by a software that measures the interval between a visual stimulus and response, and the performance of front crawl swimming was measured by a test which allows to evaluate and score the swimming technique. The Student t test for independent samples was used and significance level was set at 5%. Results showed that there was a difference between the 2 groups in SRT (G1 = .341s e G2 = .271s; t = ˗ 3.070; p = .001; TE= 0.60), and CRT Time (G1= .651s e G2= . 492s; t = ˗ 4.016; p = .001; TE= 0.63). A moderate correlation was found between G1 (beginner) and TRE (Advanced) (r = -0.560, p = 0.046), and G2 (advanced) and TRS (Advanced) (r = -0.685, p = 0.010). We conclude that TR is important for success in the front crawl performance since its improvement results in lower time costs in subjects at an advanced stage.
