Abstract:

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 Nagamine 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 into certain people.
