摘　　要：背景:在体脂率测定的众多方法中,"水下称重法"是公认的"黄金标准",然而水下称重过程需要复杂的实验设备且测量技术繁琐,难以在人数众多的高校中实施,需要寻找方便、简洁的间接推算方法。目的:以广西高校男学生体质参数与体脂率的相关分析结果为基础,建立广西高校男生体脂率推测方程。方法:抽取在校大学男生435人,随机分为方程建立组(n=306)与验证组(n=129)。建立组以部分体质参数为自变量,以水下称重测量的体脂率为因变量,采用逐步多元回归分析,建立体脂肪率回归方程;将验证组受试者相对应的指标对新建立的方程进行回代验证;对新建方程与日本长岭-铃木方程推测值进行比较。结果与结论:成功建立广西高校男生体脂率推测方程;体脂率推测方程经回代验证显示实测值与方程推算值差异无显著性意义(P=0.150);新建方程与日本长岭-铃木方程推测值之间差异具有非常显著性意义(P=0.003)。结果可见日本长岭-铃木方程不适合用于广西高校男生体脂率的推算;以广西高校男学生体质参数与体脂率的相关分析结果为基础,通过逐步多元回归分析、回代验证,初步建立广西高校男生体脂率推测方程,建议在相对应的人群中使用。BACKGROUND： Among the methods of measuring the body fat rate, underwater weighing method is regarded as gold standard. However, in view of its complicated experiment instrument and tedious technique, the underwater weighing method is hardly applied in the large-scale universities. Therefore, it is necessary to search a simple and concise indirect calculating method. OBJECTIVE： To establish a speculative equation of body fat rate among male college students based on the corelationship analysis between physical capacity parameters and body fat rates. METHODS： A total of 435 students were included and randomized into equation group （n=306） and testing group （n=129）. The stepwise regression analysis was performed among the equation group to establish the speculative equation of fat rate with partial physical capacity parameters as the independent variables and the body fat weighed underwater as the dependent variables. The corresponding indexes of subjects in the testing group were used into the newly established equation to verify its credibility, and then a comparison between the newly established equation and equation established by Negamine and Suzuki was further carried out. RESULTS AND CONCLUSION： The speculative equation for body fat rate in male college students of Guangxi was established successfully. The validation results of the body fat rate equation established in this study showed that there were no significant differences between actual value and speculative value （P=-0.150）. There was significant difference between the newly established equation and the Japanese＇s （P=-0.003）. The equation made by Nagamine and Suzuki is not suitable to the speculation of body fat rate in male college students in Guangxi. The tentative speculative equation for body fat rate in male college students of Guangxi is reliable by the stepwise regression analysis and verify based on the results of correlation analysis between physical capacity parameters and body fat rate, so it is suggested to apply
