Allometric modeling has been used in place of simple ratio standards in order to normalize distribution of raw variables. The purpose of this study was to use allometric scaling to remove the influence of body mass on anaerobic power and to evaluate the difference between the genders. Subjects (200 females, 90 males) performed a 20-sec supramaximal sprint on a bicycle ergometer against a load equivalent to 0.075 g/kg. A computerized program monitored revolutions per minute and determined power output based on load. The mass exponent was 0.87 for peak power and 0.84 for mean power. Production of proportionality constants for each gender in each power test indicated that men produce approximately 1.4 times the power generated by women. The Fatigue Index was not significantly different between the genders. The difference between the genders in anaerobic power is comparable to the difference in strength.
