采用测试法、主成分分析法对福建省汉族大学生体质测试的19个指标进行分析,确定影响福建省汉族大学生体质健康水平的重要因素以及权重。通过实证分析,将19指标变量简化为四个主成分,分别为身体素质因子、发育形态因子、生理机能因子和柔韧耐力因子,并建立相应函数表达式。

19 indexes were analyzed in physical test of the Han-nationality university students in Fujian province through Test Method and Principal Component Analysis to determine the factors and weight that affect the Han-nationality university students5 health condi-tions in Fujian province. By Empirical Analysis, the 19 indexes were simplified into 4 principal components, that is, physical quality, de-velopmental morphology, physiology function and flexibility and endurance.
