Mayhew, J. L., Hancock, K., Rollison, L., Ball, T. E., & Bowen, J. C. (2001). Contributions of strength and body composition to the gender difference in anaerobic power. Journal of Sports Medicine and Physical Fitness, 41, 33-38.

College men (N = 113) and women (N = 175) were evaluated for anaerobic performance (Margaria-Kalamen stair run), dynamic strength (1-RM single leg-extension), and body composition (skinfolds).

Significant (99%) gender differences were accounted for by strength, % fat, and fat-free mass. When those factors were held constant by covariance, there was no difference in anaerobic power.

Implication. Body size and dynamic leg strength are major factors involved in explaining the explosive leg power difference between genders. There is no unique or specific quality that causes gender differences in explosive power.
