Summary
The effects of growth and pubertal development on bio-energetic characteristics were studied in boys aged 6–15 years (n = 144; transverse study). Maximal oxygen consumption (VO2max, direct method), mechanical power at (VO2max (\({\text{P}}_{\dot V{\text{O}}_{{\text{2max}}} } \)), maximal anaerobic power (Pmax; force-velocity test), mean power in 30-s sprint (P 30s; Wingate test) were evaluated and the ratios between Pmax,P 30s and\({\text{P}}_{\dot V{\text{O}}_{{\text{2max}}} } \) were calculated. Sexual maturation was determined using salivary testosterone as an objective indicator. Normalized for body massVO2max remained constant from 6 to 15 years (49 ml· min−1 · kg−1, SD 6), whilst Pmax andP 30s increased from 6–8 to 14–15 years, from 6.2 W · kg−1, SD 1.1 to 10.8 W · kg−1, SD 1.4 and from 4.7 W · kg−1, SD 1.0 to 7.6 W · kg−1, SD 1.0, respectively, (P < 0.001). The ratio Pmax:\({\text{P}}_{\dot V{\text{O}}_{{\text{2max}}} } \) was 1.7 SD 3.0 at 6–8 years and reached 2.8 SD 0.5 at 14–15 years and the ratioP 30s:\({\text{P}}_{\dot V{\text{O}}_{{\text{2max}}} } \) changed similarly from 1.3 SD 0.3 to 1.9 SD 0.3. In contrast, the ratio Pmax:P 30s remained unchanged (1.4 SD 0.2). Significant relationships (P < 0.001) were observed between Pmax (W · kg−1),P 30s (W · kg−1), blood lactate concentrations after the Wingate test, and age, height, mass and salivary testosterone concentration. This indicates that growth and maturation have together an important role in the development of anaerobic metabolism.
