OBJECTIVE: The aim of the present study is to compare the values of the maximal oxygen uptake (<IMG SRC="/img/revistas/rbme/v9n3/17260s01.gif" WIDTH=10 HEIGHT=12>O2 max) during two consecutive bouts in Wingate tests for arms and legs in swimmers (S) and water polo players (WP). METHODS: Sample - seven national level athletes (4 S and 3 WP), age 17,90 ± 2,14 years, body mass 71,41 ± 6,84 kg, height 176,65 ± 7,02 cm, % body fat 13,23 ± 4,18. Two Wingate bouts with 30 sec each with 3 min interval between them, for arms and legs in alternated days. Oxygen uptake: breath-by-breath using the gas analysis system K4 b² Cosmed. Statistical analysis: Wilcoxon test for dependent variables and Kolmogorov-Smirnov test for independent variables. RESULTS: The mean values found at the <IMG SRC="/img/revistas/rbme/v9n3/17260s01.gif" WIDTH=10 HEIGHT=12>O2 peak (P<IMG SRC="/img/revistas/rbme/v9n3/17260s01.gif" WIDTH=10 HEIGHT=12>O2), mean power (MP) and peak power (PP) for each bout of the Wingate test, for arms and legs. For Arms: P<IMG SRC="/img/revistas/rbme/v9n3/17260s01.gif" WIDTH=10 HEIGHT=12>O2 = 55.16 ± 5.72 ml.kg-1.min-1, MP = 5.28 ± 0.59 watts.kg-1 and PP = 6.71 ± 0.88 watts.kg-1 got in the first bout (1st Arms) and P<IMG SRC="/img/revistas/rbme/v9n3/17260s01.gif" WIDTH=10 HEIGHT=12>O2 = 60.12 ± 6.10 ml.kg-1.min-1, MP = 5.03 ± 0.40 watts.kg-1 and PP = 6.25 ± 0.51 watts.kg-1, got in the second bout (2nd Arms). For legs: P<IMG SRC="/img/revistas/rbme/v9n3/17260s01.gif" WIDTH=10 HEIGHT=12>O2 = 55.66 ± 6.85 ml.kg-1.min-1, MP = 4.75 ± 1.79 watts.kg-1 and PP = 7.44 ± 1.96 watts.kg-1 got in the first bout (1st Legs) and P<IMG SRC="/img/revistas/rbme/v9n3/17260s01.gif" WIDTH=10 HEIGHT=12>O2 = 62.09 ± 5.99 ml.kg-1.min-1, MP = 4.28 ± 1.47 watts.kg-1 and PP = 6.68 ± 1.63 watts.kg-1 got in the second bout (2nd Legs). DISCUSSION AND CONCLUSION: All variables studied did not present significant difference among arms and legs, as much the first as the second bout for arms for P<IMG SRC="/img/revistas/rbme/v9n3/17260s01.gif" WIDTH=10 HEIGHT=12>O2 (p < 0.05). There was no difference between the PM mean values of the first and the second bout. But the mean of the second bout of legs was significant smaller than the first bout (p < 0.05). For the PP variable there was no difference among the mean values to the first and second bout as much for arms as for legs. It looks like to exist larger magnitude to O2 adjustment for arms than legs, that could be associated to specific demands to which S and WP athletes are daily submitted in their trainings.
