Aim: The purpose of this study was to determine if it was more appropriate assignment of the load of the Wingate test according to the lean body mass in young males. Methods: Wingate tests were performed on a Monark cycle ergometer by using loads of 75, 85, 95 g.kg-1 for the body weight and 90, 100, 110 g.kg-1 for the lean body mass on 24 untrained young males. These loads were applied randomly to the participants. Pedal revolutions for every 5-second were counted during the test and the peak power, the mean power and the fatigue index were calculated. Results: The peak power outputs of the Wingate tests in which 100 and 110 g.kg-1 loads were used for the lean body mass were significantly higher than the peak power outputs obtained from the tests in which 75 g.kg-1 loads were used for the body weight. None of the mean power outputs obtained from the loads was significantly higher than the others. Conclusion: We concluded that assignment of the load of the Wingate test according to the lean body mass would be more appropriate in young males. 100 or 110 g.kg-1 loads for the lean body mass can be used as they result in significantly higher peak power outputs.
