MARTIN, R. J. F., E. DORÉ, C. A. HAUTIER, E. VAN PRAAGH, and M. BEDU. Short-Term Peak Power Changes in Adolescents of Similar Anthropometric Characteristics. Med. Sci. Sports Exerc., Vol. 35, No. 8, pp. 1436–1440, 2003. Purpose The present study was undertaken to examine changes of cycling peak power (Pmax), optimal pedaling frequency (Vopt), and optimal pedaling force (Fopt) with age in subjects with the same lean leg volume (LLV), leg length (LL), and percentage body fat (%BF). Method A total of 132 males aged 9.5–16.5 volunteered for this study. The population was divided into prepubertal (G1), pubertal (G2), and postpubertal (G3) groups. Within G1, G2, and G3, although the subjects were divided into three different age subgroups, there were no significant differences for LLV, %BF, and LL. Results Results showed that within G1, G2, and G3, Pmax increased significantly with age. Optimal velocity (Vopt) increased significantly with age in G1, whereas optimal force (Fopt) increased significantly with age into the other groups (G2 and G3). Conclusion This study demonstrated that when anthropometric characteristics were controlled (LLV, LL, and %BF), Pmax and its two components (Vopt and Fopt) still increased with age. This indicates that other factors of qualitative nature have to be considered when determining Pmax, Vopt, and Fopt.
