The purpose of this study was to investigate the relationship between biological age, habitual physical activity and anthropometrical and physiological characteristics in 12- and 13-year-old schoolboys (n = 70).
At the beginning and the end of the school year 1971/2 biological age was determined by measuring skeletal age from left hand X-ray photographs. Habitual physical activity was determined by questionnaire interview and pedometers.
All anthropometrical characteristics showed significant correlations (P less than 0.05) with skeletal age except for bicipital and tricipital skinfolds. Out of 9 physical fitness tests handgrip was the only test that showed a significant correlation (0.52) with skeletal age. Pedometer scores gave significant negative correlations (P less than 0.05) with anthropometrical characteristics except for tricipital skinfold. The fitness tests bent arm hang, 12 min run walk, sit and reach and W-170 showed significant correlations (P less than 0.05) with pedometer scores.
本研究旨在调查12至13岁男学生（n = 70）的生物学年龄、习惯性身体活动与人体测量学及生理学特征之间的关系。
在1971/2学年开始和结束时，通过测量左手X线照片的骨骼年龄来确定生物学年龄。通过问卷调查和计步器来确定习惯性身体活动。
除肱二头肌和肱三头肌皮褶外，所有人体测量学特征均与骨骼年龄呈显著相关性（P < 0.05）。在9项体能测试中，握力是唯一与骨骼年龄呈显著相关性（0.52）的测试。计步器得分与除肱三头肌皮褶外的人体测量学特征呈显著负相关（P < 0.05）。体能测试中的屈臂悬垂、12分钟跑走、坐立前屈和W - 170与计步器得分呈显著相关性（P < 0.05）。
