As an important force of national social and economic development, the improvement and promotion of college students' physical health has always been the focus of close attention of the state and universities.Based on the physical health test data of college students in a University in Beijing in 2020, this study uses the cluster analysis of K-means algorithm, college students who score below 60 points according to the male, the female gender classification of two groups of data analysis.To study the physical characteristics of different categories of students with less than 60 points, and provide personalized exercise suggestions, as well as specific countermeasures for the school in the teaching of physical education courses. The results show that: (1) The physical health scores of female students with weak physical constitution can be divided into four groups (The first is weak explosive power; The second is weak core strength and lower limb explosive power; The third is weak endurance quality; Fourth,weak physical quality);(2)The physical health scores of male students with weak physical fitness can be divided into three groups (the first is weak flexibility; The second is weak physical quality; Third, weak explosive power of lower limbs) ; (3) The female group is characterized by lack of explosive power, speed and endurance, while the male group is characterized by extremely lack of upper body strength and weak explosive power and flexibility of lower limbs.
