对6682名7~18岁健康、发育正常的男女学生形态、体成份与肺活量进行了测量和相关分析,结果表明:肺活量与身高、胸围、体重等呈正相关,与皮脂厚度呈负相关。在做典型相关分析时,其影响因素的相关系数:身高>瘦体重>胸围>体脂百分比。由此建议,在推算肺活量时,除用身高、胸围、体重等外,皮脂厚度和瘦体重也是不可抛弃的因素。
The morphological, body composition and vital capacity of 6682 healthy male and female students aged 7-18 years were measured and correlated with each other. The results showed that vital capacity was positively correlated with height, chest circumference and body weight, and negatively correlated with sebum thickness. Correlation coefficients of influencing factors in the canonical correlation analysis were: height> lean mass> bust> percentage of body fat. It is suggested that in estimating lung capacity, in addition to height, chest circumference, weight, etc., sebum thickness and lean body mass is also an indispensable factor.
