Resumo

The main barrier to the wide use of maximal accumulated oxygen deficit (MAOD) is the considerable time required to apply several sub-and supra-maximal exercise sessions. The main question of this study was whether the determination of MAOD using a single supramaximal exercise session (MAOD(ALT)) is valid and reliable in running. We investigated the effects of the supramaximal exercise intensity (A) and the reliability of a single supramaximal exercise session (B) to assess MAOD in treadmill running. For this aim 29 subjects participated in A \& B studies with single allocation ``A{''} (n = 15) and ``B{''} (n = 14). The conventional MAOD and 8 MAOD(ALT) were determined in exhaustive efforts varying between 100-150 % at an intensity associated with maximal oxygen uptake (i(V) over dotO(2MAX)). In B study 2 supramaximal efforts were applied to analyze the test-retest reliability. Non-significant differences were found between MAOD and the 8 values of MAOD(ALT). Despite the MAOD being statistically correlated with the MAOD(ALT) 100 % i(V) over dotO(2MAX) (0.49 < r > 0.59), MAOD(ALT) determined at 115 % of i(V) over dotO(2MAX) (52.4 +/- 1.7 mL.kg(-1)) presented the higher correlation values (0.65 < r > 0.77) and concordance. In addition, the MAOD at 115 % of i(V) over dotO(2MAX) presented high test-retest reliability. MAOD(ALT) determined at 115 % of i(V) over dotO(2MAX) was a valid and reliable method to assess MAOD in running. (AU)
