山西省大学生体质健康区域差异性分析——以大同和阳泉地区为例

Shanxi College Students Physical Health Regional Difference Analysis——A Case Study of Datong and Yangquan

通过对山西大学商务学院16 731名学生的体质测试,选取大同和阳泉地区学生的成绩进行主成分分析,明确各变量对大学生体质健康的主要影响,分析出BMI和体重是直接影响学生体质的因素.研究显示,使用主成分分析法不仅能够规避无偏估计的假设性要求的相关条件,而且可以把一些共同的项目联系的信息渠道和部分条件的相关指标进行分析;体重和BMI值是严重影响体测成绩的指标,特别是BMI对力量、耐力、速度、柔韧性和灵敏度等方面的影响.

16,731 students in Shanxi University Business College were given physical measurements to determine the influence of variables on students＇ physical health,with the analysis based on tested students from Datong and Yangquan. Results showed that BMI and weight directly affect students＇ physical health; principal component analysis can not only avoid the relevant conditions of unbiased estimation hypothetical requirements,but also combine information channels of joint project links with relevant indicators of partial conditions; additionally,weight and BMI values are important indicators of physical measurement results. Particularly,BMI affects strength,endurance,speed and flexibility. Furthermore,the deep analysis of students＇ physical fitness helps find out better ways to improve it.
