The purpose of this study was to clarify the effects of warm up (W-up) intensity and length before Wingate anaerobic test. Experiments were performed under mild environment in a climatic chamber (room temperature: 24 ℃ , relative humidity: 50 %). The subjects were 6 healthy trained males, and their mean age, height and weight were 21.7±0.5 years, 172.5±7.5 cm, and 63.8±6.6 kg, respectively. Before subjects entered a climatic chamber, they performed 5 sec maximum voluntary contraction with fixed right leg and electromyograms were measured from the rectus femoris (RF) and vastus laterais (VL). After entering the climatic chamber, they rested on a chair for 30 min and they performed various W-up on a cycle ergometer. W-up was performed under three conditions of intensity (low, middle, high) and three length conditions (5 min, 15 min, 30 min), for a total of 9 experiments. The subjects performed Wingate anaerobic test (W-AnT) after W-up. During W-up, respiratory gas exchange and muscle temperature were measured. During W-AnT, performance was measured and electromyograms were recorded. Low intensity or short length W-up did not significantly increased muscle temperature. MPF and %iEMG of RF were low at the beginning of W-AnT, and W-up did not markedly improve peak power. On the other hand, middle: 30 min and high: 15 min W-up significantly increased muscle temperature and MPF of VL was higher than for short or low intensity W-up. High: 30 min W-up increased muscle temperature more than middle: 30 min and high: 15 min, but no corresponding improvement in performance was noted. In conclusion, about 30 min in middle intensity and about 15 min in high intensity were most effective W-up for W-AnT.
