The Effect of Restricting the Visual Perceptual Task in the Temporal Organization of Crawl Swimming: Surface Characteristics Brito, c.A.F. 1 , Belvis, W.c. 2 , oliveira, M. 2 1 Municipal University of São Caetano do Sul (USCS), São Caetano do Sul, Brazil 2 Competitive Team DETUR, São Caetano do Sul, Brazil The objective of this study was to observe how disturbing swimming skill execution can influence the superficial parameters of front crawl. There was mixed random-systematic sampling among 5% of high-ability swimmers from São Caetano do Sul, enrolled with DETUR in 2008 (n=106). Disturbance was carried out by light shone onto the retina, forming a configuration according to the degree of complexity. The subjects swam at a natural rhythm. Data were analyzed using Mauchly’s Test of Sphericity and repeated measures ANOVA (Contrast). Probability was 5% (p

Data were analyzed by Mauchly's Test of Sphericity and for ANOVA time, was when used compared for repeated to without measures restriction (Contrast). If (21.68±2.69; the interaction 21.51±2.5; effect was significant, the effect of each main factor was analyzed by contrasts within of the levels 22.73±3.31 s vs. 20.33±1.92 s, respectively) and lower values for speed, of the other factor. Data were analyzed by using the program SPSS (version 13.0), and P values≤0.05 were considered as significant. when compared to without restriction (1.17±0.15; 1.18±0.14; 1.12±0.15 m·s-1 vs. 1.24±0.12m·s-1 , respectively, p
