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 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. Verf.-Referat
