Hebei Province Sport College Athletes' Body Composition Study

Body composition affects enginery, sports ability and achievement. The article makes use of DEXA measuring the character of BF%, BMC and BMD of different sports items undergraduate athletes in Hebei province. Comparing to the correlation of BF% ,BMI and WT/H*1000, and discussing the character of BMI of different sports items and the credibility of BMI and WT/H*1000 at the aspect of evaluating athletes fatness and body configuration in order to accumulating BF%,BMC and BMD for undergraduate athletes.With the methods of DEXA, this paper investigates undergraduates of the Hebei normal university from 7 sports items athletes of kickboxing, long-distance running, sprint, football basketball, rassle and jump .We acquire the data of the different parts BF%, BMC and BMD of head and ears, head, upper limbs, lower limbs, trunk. We adopt SPSS13.0 to description Stat, Pearson correlation analysis, single factor square analysis and the result show as x±S.The results: 1. The male undergraduate athletes'BF% lower than the female's in Hebei province. The Judo athlete BF% is biggest and has with other project differences(P<0.05). 2. The order of undergraduate athletes'part BF% was the trunk'?the lower limbs'?the upper limbs'. 3. The order of their part BMD and BMC'was the lower limbs'? the trunk'?the upper limbs'.4. Hebei Province undergraduate basketball athletes BMD is bigger than others. 5. The undergraduate athletes BMD and BMC of judo and basketball were higher than the others. 6. It was positive correlation between BMC and WT. 7. Hebei Province componental movement project male university student athletes BMI is bigger than female BMI mainly to concentrate to the normal range, the project arrangement has the sex difference and the project difference. 8. There is componental Correlation between movement project undergraduate athletes BMC and WT in Hebei Province.Conclusion: 1. Hebei Province university student athletes BF% was higher than the domestic and foreign top athletes BF%, the adult BF% male university student athletes were in "normally" the level, the female university student athletes were in " higher" the level. Hebei Province university students Judo, basketball, Tae Kwon Do, soccer athlete BF% relative bigger, the dash and the long-distance race athletes BF% relative were smaller. Judo, Tae Kwon Do and basketball athlete's part BF% highest, the dash and jumps the athlete to be next, the long-distance race athletes various spots BF% were lowest. 2. Hebei Province university student athletes whole and the partial physiological load of exercise and the movement intensity were possibly the important reason which BMC and BMD increases. The Hebei Province university student of basketball, the Judo and jump athletes' whole BMC and BMD highest, the soccer athletes were next, the Tae Kwon Do, the dash and the long-distance race athletes were lowest. Basketball and Judo athlete upper limb BMC bigger, the basketball, the soccer and jump athletes lower limb BMC in a big way, the basketball and Judo athletes torso BMC was bigger. Judo and basketball athletes upper limb BMD bigger, Tae Kwon Do, soccer and under basketball athletes'BMD bigger, the basketball and Judo athletes torso BMD was bigger. 3. BMI may take appraises the Hebei Province male university students Judo, the TaeKwon Do, the sprinter and the Hebei Province female university student soccer, the basketball athletes obese degree target, but BMI with BF% unifies may better appraise athlete's muscle sufficient solidity.
