目的:采用R型聚类分析综合评价公安院校特警专业学生体质情况。方法:以60名浙江警察学院特警专业学生为研究对象,分别对其身体形态、机能、素质等指标进行测试并计算派生指标,采用R型聚类分析从上述指标中得出6项典型身体形态、机能、素质指标:骨骼肌含量、体脂百分数、肺活量/身高、右手直接反应时、1000米跑和立定三级跳远。计算特警专业学生这6项典型指标的平均数xi、标准差si和权重系数Ri。根据体质综合评价模型和评分标准计算特警专业学生的体质综合评分及评价等级。结果:本组特警专业学生体质等级百分比分别为:上等6.9%,中上等12.07%,中等56.90%,中下等13.79%,下等8.62%。
Objective: To use R-cluster analysis to comprehensively evaluate the physique of special police students in public security colleges and universities. Methods: Sixty special police majors from Zhejiang Police College were selected as research objects, their body shape, function and quality were tested and their derivatives were calculated. Six typical body morphologies were obtained by R-cluster analysis , Function, quality indicators: skeletal muscle content, body fat percentage, vital capacity / height, right hand direct reaction, 1000 meters run and standing triple jump. Calculate the average number xi, standard deviation si and weight coefficient Ri of these six typical indicators of SWAT majors. According to the physique comprehensive evaluation model and grading standards, the SWAT students’ comprehensive physical fitness score and evaluation grade are calculated. Results: The percentages of physique grade of the SWAT students in this group were: 6.9% of the top class, 12.07% of the middle and upper class, 56.90% of the middle class, 13.79% of the middle and lower middle class, and 8.62% of the lower class.
