The purpose of this study was to determine the differences in anaerobic power between males and females and the contribution of anthropometric variables in accounting for these differences. Eighteen female and nineteen male subjects performed the Wingate test as a measure of anaerobic power AnP. Each subject pedalled maximally for 30s against a resistance of 4.41 joulespedal revolutionkg body weight on a modified Monark ergometer which allowed instantaneous application of resistance. Revolutions were determined by a computer interfaced frequency counter. Thigh volume TV by water displacement, lean body mass LBM from skinfolds and body weight BW were used as anthropometric variables. Absolute AnP of males was significantly higher than females, as were pedal revolutions. The difference between genders decreased when power was expressed in terms of TV, BW and LBM, in that order. These data reveal that a larger portion of the between gender variation compared to the within gender variation in AnP can be accounted for by the anthropometric variables. However, a significant portion remains that must be explained by the individual muscles potential for glycolytic energy production.
