Abstract

SMIDT, Guilherme Ribas et al. Analysis of reaction time performance engine from the practitioners of teenagers swim crawl. Motri. [online]. 2015, vol.11, n.3, pp.11-19. ISSN 1646-107X.  https://doi.org/10.6063/motricidade.2773.

The 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.
