In order to judge the effect of moderate sports training on the anthropometric characteristics and aerobic capacity of boys before and during puberty, a comparative study was conducted of 140 children, 94 of whom were not undergoing any specific training and 45 of whom were spending more than 3 hours a week practising swimming. The boys were divided into three maturity groups according to pubic hair status: prepubertal, pubertal, and end of puberty. The study shows greater maximal oxygen uptake in absolute terms, body weight, lean body mass, chest circumference, arm circumference, and arm muscle area for the swimmers. The morphological differences between the swimmers and non-swimmers concern physical characteristics generally involved in swimming. The difference in aerobic capacity, however, may be in part due to the morphological changes engendered by training; a longitudal study would confirm this. It is suggested that anthropometric indicators of arm muscles may be used in the biological supervision of swimming training.
为了判断适度体育训练对青春期前及青春期男孩人体测量特征和有氧能力的影响，对140名儿童进行了一项对比研究，其中94名未接受任何特定训练，45名每周花超过3小时练习游泳。根据阴毛状态，将男孩分为三个成熟度组：青春期前、青春期、青春期结束。研究表明，游泳者在绝对最大摄氧量、体重、瘦体重、胸围、臂围和臂肌面积方面更大。游泳者和非游泳者之间的形态差异涉及游泳通常涉及的身体特征。然而，有氧能力的差异可能部分归因于训练引起的形态变化；纵向研究将证实这一点。建议将臂肌的人体测量指标用于游泳训练的生物学监测。
