不同体重指数与大学生体质健康指标表现差异的研究

为探讨不同的体重指数与大学生各项体质健康指标的关系,以4802名大学生为研究对象,分别实施各项体质健康测验.依其体重指数将学生分为低体重、正常体重、超重及肥胖四组,以体重指数为自变量,其他体质健康指标为因变量,进行单因素方差分析,并进行均数的多重比较。结果显示:体质健康指标在不同的体重指数之间的变化趋势各不相同;正常体重学生心血管功能、呼吸机能、手臂力量、下肢爆发力均优于低体重组(除呼吸机能外)、超重、肥胖组学生;低体重(除呼吸机能外)、超重、肥胖对学生身体机能、素质均产生负面影响。

Research on Difference between Body Mass Index Classification and Physical Fitness of College Students

This study explored the effects of body composition on physical fitness in a study of 4,802 college students.Subjects were divided into four groups according to their body mass index: low weight,normal weight,overweight and obese.With body composition as independent variable and other physical health indicators as the dependent variable,univariate analysis of variance and multiple comparisons for the average were performed.The result showed that: the variation on physical fitness indicators among the different body composition differs from one another;the cardiovascular function,respiratory function,arm strength and lower limb explosive power of normal-weight group is superior to the low weight(except for respiratory function),overweight and obese group;low weight(except for respiratory function),overweight and obesity all have negative effects on students’ physical function.
