Índices fisiológicos associados com a performance aeróbia de corredores nas distâncias de 1,5 km, 3 km e 5 km

Abstract

IntroduçãoVários estudos têm procurado determinar os índices fisiológicos capazes de predizer a performance aeróbia e que, também, possam ser utilizados como referência para prescrição e controle dos efeitos do treinamento (BRANDON, BOILEAU, 1987;BRANDON, 1995;DENADAI, 1996;DENADAI;ORTIZ; MELLO, 2004).Tradicionalmente, os índices aeróbios mais estudados para a predição da performance durante as corridas de endurance são o consumo máximo de oxigênio (VO 2 max), a velocidade correspondente ao VO 2 max (vVO 2 max), o tempo de exaustão na vVO 2 max e a economia de corrida (EC) (DENADAI, 1996;DENADAI;ORTIZ; MELLO, 2004;BILLAT et al., 1999;DENADAI, 1999).Embora o VO 2 max seja o parâmetro fisiológico que melhor expressa a aptidão cardiorrespiratória do indivíduo (BASSETT;HOWLEY, 2000), o mesmo apresenta um baixo poder discriminatório da performance em um grupo homogêneo de corredores (DENADAI; ORTIZ: MELLO, 2004). Por outro lado, a velocidade correspondente ao VO 2 max (vVO 2 max) é um índice determinante para a predição de performance em provas de média e longa duração (NOAKES; MYBURGH; SCHALL, 1990). Sobretudo, porque este índice Motriz, Rio Claro, v.18 n.4, p.690-698, out./dez. 2012 Artigo OriginalÍndices fisiológicos associados com a performance aeróbia de corredores nas distâncias de 1,5 km, 3 km e 5 km Physiological indices associated with aerobic performance in the distances of 1,5 km, 3 km and 5 kmAbstract: The aim of this study was to analyze the association between physiological indices of aerobic power and aerobic capacity with the performance in the distances of 1.5 km, 3 km and 5 km. Nine endurance runners performed the following protocols: a) test to determine the VO 2 max, vVO 2 max and OBLA; b) 2-5 tests in alternate days of 30 minutes with constant speed to determine the vMLSS; and c) performances (P). The linear correlation of Pearson or Spearman and multiple regression were applied to determine the relationships among the indices and the performance. It was found a significant correlation only of the vVO 2 max with the performance of 1.5 km (r = 0.78) and 3 km (r =0.81). Thus, it can be suggested the inclusion of training sessions at or near vVO 2 max on weekly periodization. Based on the present findings, it can be concluded that the performance prediction through the indices of power and aerobic capacity depend on the distance and duration of the race.

Running velocity at maximum oxygen uptake and at maximum effort: important variables for female military pentathlon

“…The authors inferred that vVO 2max and the time in which they continued after reaching the VO 2 plateau (Tlim) explained 88% of the variation in endurance athlete performance in a 1500 m race. This variable was also studied by Guglielmo et al 18 , who carried out several protocols in nine endurance athletes, in order to identify variables associated with performance in 1500 m, 3000 m, and 5000 m races. vVO 2 max was the only variable that determined performance in 1500 m and 3000 m races, showing a negative correlation with time at the different distances (r = -0.78 and r = -0.81 respectively).…”
