BODY COMPOSITION PARTIALLY CONTRIBUTES TO POWER DIFFERENCES BETWEEN THE GENDERS
Dore, E., Bedu, M., & Van Praagh, E. (1998). Anaerobic power output: Sex-related developmental changes. Medicine and Science in Sports and Exercise, 30(5), Supplement abstract 843.
The purpose of this study was to examine the effects of age and body composition on short-term cycling power output in prepubescent, pubescent, and postpubescent girls (N = 465) and boys (N = 443).
Peak power and peak power to body mass or lean leg volume ratios increased significantly in both genders until 18 years. Peak power was similar for both genders until 14 years but from then on boys scored significantly higher. When peak power was standardized for body mass or lean leg mass the differences were reduced but still existed.
Other factors as well as body composition account for power differences between the genders during growth.
Implication. Body composition is one factor that partially contributes to gender differences in peak power in maturing individuals.
