5～6岁儿童体格形态和体能关系的典型相关分析

为了探讨儿童体格形态和体能测量指标的关系.方法采用典型相关分析方法,对201名5～6岁儿童进行了体格形态和体能测试,指标包括:体重、身高、胸围、立定跳远、20米跑时间和单腿站立时间.结果仅一对典型变量有统计学意义(P<0 .001),其特征值为 0.386,贡献率达 93.66%,典型相关系数为0.528,表明学龄前儿童的体格形态与体能发育之间有相关性.典型变量中,身高和立定跳远的载荷最大.结论评价学龄前儿童体格形态与体能的关系时,身高和立定跳远是最好的预测指标.

Canonical Correlation Analysis on Physical and Diathetic indices of Preschool Children

To survey the relationship between physical and diathetic indices of preschool children. Method 201 children aged 5 - 6 years were investigated on the development of physical and diathetic indices, including weight, height, chest circumference, standing long jump, time of 20 meter running and time of one leg standing. Results It was merely that the one pair of canonical variable was statistically significant ( P value less than 0. 001) and its eigenvalue was 0. 386,which accounted for 93. 66 percent of these indices. The canonical correlation coefficient was 0. 528, that indicated the physical indices associated with the diathetic indices among preschoolers. In canonical variables the height and long jump were the maximum loading variables. Conclusions The variables of height and long jump were good predictors of relationship between physical and diathetic indices in the children.
