This study examined the extent to which aerobic power could account for performance during a 30-s max-effort test. Physically active women (n = 41) and men (n = 34) underwent a treadmill test for aerobic power and the Wingate test for anaerobic power and fatigue. Pearson product-moment correlation coefficients were calculated from Wingate segments of various durations and temporal positions. For aerobic and anaerobic power, all correlations (positive) in both genders were significant (p <= 0.05) but low, except for those of the first two 5-s segments in the men. For fatigue indices involved in significant negative correlations (all were in the women's group), aerobic power explained only 10 to 19% of the common variance. For anaerobic power there was a trend of stronger correlations from the longer or latter segments. For fatigue, more and stronger relationships were found with the latter segments and with a longer spacing between contrasted segments. This study supports previous evidence for a decreasing role of aerobic power with decreasing duration of a target max-effort performance.
