Resumo: | In long distance swimming competitions, the optimal pacing strategy is not well established. The objective of this study was to characterize the pacing strategy adopted by international level athletes in 800-m (female) and 1500-m (male) crawl swimming events. We analyzed the time of each 50 m splits for semi-finalists and finalists athletes of the last three world swimming championships from 2006 to 2010. The data analysis was performed through the statistic method named CHAID (Chi-Squared Automatic Interaction Detection), which is a statistic χ2 to detect a homogeneity behavior among the variables. The main results found were: for the two events analyzed, the velocity-versus-distance curve was similar to the parabolic pacing strategy (U-shaped), characterized by a significantly faster start (p<0.05) than mean velocity for the race, followed by a gradual decline invelocity in the middle splits, when athletes increase the velocity again (p<0.05) to produce an end spurt. In conclusion, these findings indicate that this pacing strategy profile can be classified as optimal for the long distances wimming events since it was preferentially adopted by international level athletes. |

Desta forma, o objetivo desse estudo foi caracterizar as EP adotadas poratletas de nível internacional em provas de natação de 800m (feminino) e 1500m (masculino) crawl. Foram analisadas as parciais de tempo (a cada 50m) dos atletas (n = 60) participantes das semifinais e finais dos últimos três campeonatos mundiais de natação, ocorridos no período de 2006 a 2010. A análise dos dados foi realizada por meio do teste estatístico CHAID (Chi-Squared Automatic Interaction Detection), que é uma estatística χ2 (qui-quadrado) para detectar comportamento de homogeneidade entre as variáveis. Os principais resultados encontrados foram: para as duas provas analisadas, o comportamento davelocidade em função do tempo mostrou-se semelhante à estratégia parabólica(formato em U), caracterizada por um início significativamente mais rápido (P <0,05), seguido por uma diminuição do ritmo no trecho médio da prova, quando ocorre um novo aumento significativo (P < 0,05) na velocidade no trecho final. Desta forma, tais achados indicam que este perfil de EP pode ser classificado como ótimo para as provas de natação consideradas de longa duração, visto que foi o perfil preferencialmente adotado por atletas de nível mundial.Universidade Federal de Santa Catarina.
