本研究的目的是研究日本青年在一年内的人体测量和身体成分的成熟相关的差异。210名13至13.99岁的日本青少年参与了这项研究。他们的成熟状态进行了评估，使用自我评估阶段的阴毛发育。生物电阻抗分析用于估计体脂百分比和瘦体重（LBM）。超声测量股前肌、小腿后肌和腹直肌的厚度。对于男孩，身高，体重和LBM在较不成熟的组低于较成熟的组。在调整实际年龄后，与成熟度相关的差异仍然显着。另一方面，在下肢和腹部的肌肉厚度值不同的组之间在阴毛发育的不同阶段，而有没有成熟相关的差异，除了在腹部测量的厚度值的LBM校正的相对值。对于女孩来说，只有大腿前部的肌肉厚度和小腿后部的肌肉厚度相对于LBM 1/3受成熟状态的显著影响，但调整实际年龄后，未发现与成熟相关的显著差异。至少对于13岁的日本男孩和女孩来说，成熟状态影响男孩的身体尺寸，但不影响女孩，成熟对下肢和躯干肌肉的肌肉发达程度的影响在两性中都较小。
The purpose of this study was to examine maturity-related differences in anthropometry and body composition in Japanese youth within a single year. Two hundred and ten Japanese youth aged from 13 to 13.99 years participated in this study. Their maturity status was assessed using a self-assessment of stage of pubic hair development. Bioelectrical impedance analysis was used to estimate percent body fat and lean body mass (LBM). Muscle thickness of the anterior thigh, posterior lower leg and rectus abdominis muscles were measured by ultrasound. For boys, height, body weight, and LBM in less mature groups were lower than that in more mature groups. The maturity-related differences were still significant after adjusting for chronological age. On the other hand, muscle thickness values in the lower extremity and abdomen differed among the groups at different stages of pubic hair development, whereas there was no maturity-related difference in the relative values corrected by LBM, except for those thickness values measured at the abdomen. For girls, only the muscle thickness at the anterior thigh and muscle thickness relative to LBM1/3 at the posterior lower leg was significantly affected by maturity status, but significant maturity-related difference was not found after adjusting for chronological age. At least for Japanese boys and girls aged 13 years, maturity status affected body size in boys, but not in girls, and the influence of maturation on the muscularity of the lower extremity and trunk muscles is less in both sexes.
