Physical efficiency tests were performed on urban school boys drawn from high socio-economic status in comparison to rural school boys. The height and weight records of the subjects indicating growing process showed that the rural boys attained less physical growth than their urban counterparts. The Vital Capacity and Peak Expiratory Flow Rate data expressed either per unit of height or body surface area were significantly lower in rual boys. these findings indicated a poor development of the thorax in the rural group. However, the determined grip strengths for both the group were similar. The grip test might reflect improvement of muscle mass in case of rural boys as a result of regular physical activity employing the arm muscles.
对来自高社会经济地位的城市男学生与农村男学生进行了体能效率测试。受试者的身高和体重记录表明了生长过程，结果显示农村男孩的身体发育程度低于城市同龄人。农村男孩以身高或体表面积每单位计算的肺活量和呼气峰值流速数据明显更低。这些发现表明农村组的胸廓发育较差。然而，两组的握力测定结果相似。握力测试可能反映出农村男孩由于经常进行使用手臂肌肉的体育活动，肌肉质量有所改善。
