摘要
目的探讨中小学生体格成分与身体功能的关系,为制定学生体质干预措施提供参考。方法利用宁波市3 087名6～18岁中小学生2010年全国体质健康调研的部分数据,对年龄、身高、体重、腰围、胸围和臀围等体格成分与立定跳远、50 m跑、握力、坐位体前屈、肺活量等身体功能指标进行典则相关分析。结果共得到5对典则变量。反映男、女两组典则相关关系主要是第1对典则变量,典则相关系数的贡献率分别达到0.977和0.957(P值均<0.01)。对不同性别的典则变量作进一步分析表明,年龄、身高、体重与男生50 m短跑、立定跳远和肺活量关系密切,而与女生肺活量、立定跳远和坐位体前屈关系密切。结论学生的体格指标与身体功能素质有着密切联系,利用典则相关分析能找出体格变量与功能变量的主要影响因素之间的关系。
Objective To investigate the relationship of the anthropometric indexes and function indexes in primary and secondary students. Methods A cross-sectional descriptive study was done among the 3 087 students recruited in Ningbo. Canoni- cal correlation was analyzed by using of anthropometrie indexes such as age, height, weight, waist, chest circumference and hip circumference and physical function indexes such as standing long jumping, 50 meters running, grip strength, sitting trunk flexion and vital capacity. Results It was found that there were five pairs of canonical variables in the result of the canonical correlation of anthropometric indexes and function indexes by gender. The first pairs of variables were the main variables of reflect the canonical correlation relationship in male or female, contributing proportion of the canonical correlation coefficients were 0.977 and 0.957 （ P 〈0.01）. Canonical correlation analysis showed that correlation between anthropometric indexes and physical function indexes in boys mainly attributed to correlation between age, height, weight, and fifty meters running, standing long jumping and vital capaci- ty, and in girls vital capacity, standing long jump and sitting trunk flexion. Conclusion Anthropometric indexes were closely re- lated with physical function indexes in primary and secondary students. Correlation analysis could find out the relationship between the main influencing factors of the anthropometric indexes and physical function indexes.
