RESUMO
PURPOSE: To compare the results of equations for estimate of the indirect maximal oxygen consumption with obtained them in test ergoespirometric in young individuals. METHODS: Fifty-two individuals of the masculine sex were submitted to the test of effort with it analyzes direct of gases in treadmill for the determination of the maximum consumption of oxygen (VO2máx). The progressive protocol was used with load increment to each one minute. The obtained results were compared ace equations of Jackson et al and the one of Mathews et al. For the statistical analysis of the results the test of multiple comparisons corrected by the test of Bonferrone was applied. The significance level was of p < 0.05. RESULTS: The average of age was of (21.06 +/- 2.75) years; body mass (70.85 +/- 9.15); thin mass (62.69 +/- 6.86); fat mass (8.30 +/- 4.77); percentile of fat (11.34 +/- 5.45) and maximun heartrate of (191.73 +/- 7.84). The equations of Jackson et al (VO2máx = 49.29 +/- 2.95) for a standard mistake of (EPE = 0.41) and Mathews et al (VO2máx = 37.43 +/-. 2.14) with a (EPE = 0,31) presenting tendency in underestimating the consumption of oxygen for the sample that was of (VO2máx = 55.34 +/- 8.34) for a (EPE = 1.16), being observed significant difference in relation to measure of the VO2máx obtained in test of effort (p < 0.05), for the value of Wilks'E = 0.044; F (2.500) = 539.27; p = 0.001. CONCLUSION: The equations didn't present a power of reliable estimate for the studied population.
