Objective The objective of this study was to evaluate the effects of sexual maturation on anthropometric parameters and basic physical characteristics in male adolescents aged from ten to fourteen years old. Materials and Methods The biological age was studied through the evaluation of the stage of the external genitalia development. Other evaluated characteristics were: total body mass (MCT), stature, body mass index (BMI), bone age (IO), strength, speed, agility and aerobic power. Results The results showed significant differences in all variables related to growth (chronological age, height, total body mass, body mass index and bone age) between different stages of sexual maturation. In relation to physical qualities, among maturational stages, we find significant differences in most characteristics, except for agility. Conclusions Based on this study, we may conclude that sexual maturation, evaluated by the stages of development of the external genitalia, exerts great influence on the anthropometric variables, the bone age and the basic physical characteristics of adolescent boys.
目的 本研究的目的是评估性成熟对10至14岁男性青少年人体测量参数和基本身体特征的影响。材料与方法 通过评估外生殖器发育阶段来研究生物年龄。其他评估的特征包括：总体重（MCT）、身高、体重指数（BMI）、骨龄（IO）、力量、速度、敏捷性和有氧能力。结果 结果显示，在性成熟的不同阶段，与生长相关的所有变量（实际年龄、身高、总体重、体重指数和骨龄）存在显著差异。在身体素质方面，在成熟阶段中，除敏捷性外，我们发现大多数特征存在显著差异。结论 基于本研究，我们可以得出结论，通过外生殖器发育阶段评估的性成熟对青少年男性的人体测量变量、骨龄和基本身体特征有很大影响。
