Sažetak
The purpose of this study was to verify the previous results indicating reduced peak VO2 normalized to body mass in girls of advanced sexual maturation. 31 girls aged 11 to 15 years were divided by Tanner’s
sexual maturation stages into groups of prepubertal (stage I), pubertal (stages II, III, IV) and postpubertal (stage V) girls. The peak VO2 and the ventilatory threshold were assessed with the aid of a cycloergometric incremental exercise test. Peak VO2 (l/min) was higher in pubertal than prepubertal girls (1.89±0.44 vs. 1.72±0.32, p<0.05). The difference between pubertal and postpubertal girls was insignificant. Relative maximum VO2 did not differ between prepubertal and pubertal girls. In postpubertal adolescents this value was 13% lower than in pubertal girls (p<0.05). An increase of the body mass index showed that in sexual maturation stage V the gain of body mass was relatively more pronounced than the increase in body height. The ventilatory threshold did not differ between the maturation groups.
