Study on Relationship between Sub-health Symptom and After-class Sport Exercises of Obese College Students

The factors relevant to the relationship between sub-health symptom and after-class sport exercises of obese college students are studied through using the methods of questionnaires and mathematical statistics.The results are as follows: the obesity ratio is 2.06%,the ratio of after-class sport exercises is 51.18%,obesity ratio of male students is remarkably higher than that of female students,sub-health incidence ratio of obese female students is much higher than that of male students;lower exercise frequency and intensity are main factors influencing weight reduction;with the frequency of three times per week,the normal heart rate and time span of 60 minutes per time,the exercise intensity is in more than 70% of the maximum heart rate,the sub-health incidence ratio of obese college students can be lessened remarkably.
