Differences in constitution between male college students in Single-child and Non-single-child with the same BMI
By means of literature data research and physical component analysis,the author performed a comprehensive analysis on multiple indexes such as constitution with respect to 3,406 male college students with a BMI at the same level,and revealed the following findings: the distribution of BMI of male college students is generally in a good condition,the percentage of the students with a normal figure is 75% or so;there are certain differences in constitution between singleton and non singleton male college students with a BMI at the same level,which mainly show in the followings: in quick power explosion required short distance,short time and high intensity events,singleton male students performed slightly better than non singleton male students,yet in stamina required long distance runs,singleton male students performed significantly poorer than non singleton male students;the overall score for 5 constitutional indexes for singleton male students is significantly lower than the same for non singleton male students;in the physical components of male college students,the differences in the degreased body weight and the body fat ratio are the major intrinsic factors that cause the differences in constitution,i.e.the body fat ratio is proportional to the fat content,and inversely proportional to the degreased body mass and the sports capacity of the human body;the sports factor is one of the objective factors that cause the differences in constitution between singleton and non singleton male college students.
