The purpose of this study was to investigate the influence of physiological factors which effect oxygen kinetics and energy system contribution on the power of Wingate test (WT), with focusing on the difference of aerobic capacity. Twenty three male track and field athletes (sprinters, long distance runners and decathletes) performed the WT on electromagnetic-braked cycle ergometer. The applied resistance was 7.5% of body weight, and the duration was 60 seconds. Moreover, aerobic capacity (maximal oxygen uptake [VO2max]) was determined by an incremental test, and anaerobic capacity (maximal accumulated oxygen deficit [MAOD]) was determined by a supramaximal constant load test. The oxygen uptake during each test was recorded by a breath-by-breath method. The participants were divided into two group which was high VO2max group (High group; n = 11) and low VO2max group (Low group; n = 12). In the results, although the VO2max was significantly higher in the High group, the MAOD was not significantly different between two groups. The oxygen uptake during WT was significantly higher in the High group, and the accumulated oxygen deficit during WT was significantly higher in the Low group. The aerobic contribution was significantly higher in the High group than in the Low group. In contrast, the anaerobic contribution was significantly higher in the Low group than in the High group. These results suggest that by the difference of aerobic capacity, aerobic and anaerobic energy supply contribution was different in WT.
