RESUMO

The purposes of this study were to describe: anthropometric aspects, specific physical fitness and stroking parameters; to verify relationship between anthropometric, specific physical fitness, stroking parameters and 100 meters front Crawl and to verify influence of anthropometry, specific physical fitness and stroking parameters variables over performance in 100 meters front Crawl in young swimmers. The group was composed by 24 pubertal males with 13,0 ± 0,7 years-old. Multiple regression analysis (forward method) was used to explain variance of 100 meters front Crawl velocity. Anaerobic power velocity (r² = 0,67), swimming efficiency index (r² = 0,62) and critical velocity (r² = 0,34) explained 88% of variance 100 meters front Crawl in young male pubertal swimmers. Regression model was significantly at 0,05 level and, estimative error standard was 0,03. Energetic expenditure of 100 meters front crawl has a relevant importance in predictive value of anaerobic power and inclusion of critical velocity on regression. About swimming efficiency index, effectiveness of force against water is main reason for swimming economy and, as better swimming technique, less energy will be expended resulting in better performance
