A Study On The Shape Characteristics And Body Composition Of Chinese College Male Bodybuilders

From the perspective of body shape index,this paper comprehensively measured the body circumference characteristics and body composition data of Chinese college students' bodybuilders,analyzed the differences of body circumference and body composition of different groups and levels of College Students' bodybuilders,and explored the factors affecting the body circumference and body composition of College Students' bodybuilders.Through this data,we can not only provide the basis for the college students' Bodybuilding enthusiasts to participate in the competition,but also the college coaches and college students' Bodybuilding Athletes to carry out scientific selection and effective training,narrow the gap between different groups of College Students' male Bodybuilding Athletes,and improve the performance and self-confidence of College Students' Bodybuilding Athletes.In this paper,taking Chinese college bodybuilders as the research object,71 college bodybuilders of different groups were studied and analyzed by means of literature,anthropometry,expert interview and mathematical statistics,and the factors affecting the body circumference and body composition of male college bodybuilders were discussed.Through data analysis,the following conclusions are drawn:(1)From the basic information of College bodybuilders,the number of bodybuilders in the sports department group is more than that in the general department group and higher vocational college group.Bodybuilders come from 36 universities in China.If colleges and universities are divided into Qinling and Huaihe rivers,there are 15 bodybuilders from northern colleges and universities,and 21 bodybuilders from southern colleges and universities.The development of bodybuilding and fitness major in northern colleges and universities is lower than that in southern colleges and universities,which is reflected in the source of College Students' Bodybuilding Athletes and the number of participants;the average age of College Bodybuilding Athletes is20-21,and the average training period of College Bodybuilding Athletes is1.5-2.5 years;the major direction of College Bodybuilding Athletes is mostly sports major,with a small part of science and engineering Majors.(2)In terms of the characteristics of body circumference of College Students' bodybuilders,the average circumference of body parts of bodybuilders(except waist circumference)in Higher Vocational College Group is larger than that of bodybuilders and ordinary college groups.From the perspective of limb circumference,the upper and lower limb circumference of the athletes in the higher vocational college group is larger than that in the general college group and the sports college group;the difference between the upper and lower limb circumference of the bodybuilders in the higher vocational college group is lower than that in the other two groups,and there is a significant difference between the right upper and lower limb circumference and the left upper and lower limb circumference.In terms of the characteristics of bodybuilders' three girths,the chest and hip girth of bodybuilders in Higher Vocational College Group are higher than those in general college group and sports college group,and the waist girth index of bodybuilders in Higher Vocational College Group is lower than that in other two groups.(3)From the perspective of body composition of College Students' bodybuilders,the overall level of body composition of College Students' bodybuilders in higher vocational colleges is higher than that of College Students' bodybuilders.In the two indexes of total body water and body fat percentage,bodybuilding in Higher Vocational and technical group is far higher than the other two groups,and body fat is lower than the other two groups,Bodybuilding Athletes' body water mostly shows large muscle circumference.In the body fat percentage and skeletal muscle index of bodybuilders,the body fat percentage of the athletes in the higher vocational college group is lower than that of the other two groups,but the skeletal muscle quantity is far greater than that of the athletes in the general college group and sports college group.In the three groups,there was no significant difference between protein and inorganic salt in body composition ofbodybuilders.
