幼儿生理指标与运动指标的关联分析

The connection analysis of physiology and sport indexes of children

应用灰色系统理论中的关联度分析方法对学龄前幼儿生理指标与运动指标之间的关系进行量化分析,寻找主要关联因素得出以下几个主要结果:①幼儿跑的快慢与其身高、坐高的关联度最大,投沙包与臂围的关联度最大。②身高、坐高对于运动性指标的关联度几乎相同,从量化的角度解释了医学上采用身高坐高比方法的合理性。③根据准最优原则得出运动性指标中对生理性指标按影响大小排序依次为跳远、跑、投沙包、摸高、起坐。为进一步客观评价幼儿身体素质提供准确可靠的信息。

To find out the main connection factors, the connection analytic method of grey system theory was used to analyse quantitatively the relation between the physiology and sport indexes of preschool children. The following results are as follows: ①The greatest is the connection degree between the running speed and the body height and sedentary height; the greatest is the connection degree between the distance of throwing sandbags and the girth of the upper arm. ②The body height and the sedentary height are almost equally related to the sport indexes, which quantitatively confirm the rationality of the medical approach of the ratio of the body height to sedentary height. ③According to the quasi-optimal principle, the ordinal arrangement of the degree of the sport indexes upon physiological indexes is as follows: broad jump, running, throwing sandbags, touching high goals, and sit-ups. This analysis has provided information for further objective appraisal of the constitutions of children.
