摘 要: 目的:分析女子青少年摔跤运动员身体各部位的体成分构成及体脂率、骨密度等身体成分指标,并与非运动员对照比较,揭示摔跤专项训练对青少年身体成分和骨密度的影响。方法:采用双能X光吸收法(dual-energy X-ray absorptiometry,DEXA),测试26名女子摔跤运动员和30名对照组女大学生骨密度和体成分。结果:女子摔跤运动员与对照组间体重总量没有统计学差异,但各部位(头部除外)瘦体重、骨矿含量、骨密度等均为摔跤组显著高于对照组(P<0.05),而体脂含量、体脂率均为对照组显著高于摔跤组(P<0.05),摔跤组体脂率只有对照组一半左右。结论:女子摔跤运动员体成分特征与长期的专项训练有关。运动员这一特殊群体可能需要不同于一般人群的骨密度标准。应当关注女子摔跤运动员体成分与能量平衡及其对女性特殊生理功能的影响。

Abstract: Objective: The purpose of the present investigation was to describe the body composition and bone density of female freestyle wrestlers comparing with controls. Methods: 26 female wrestlers and 30 controls recruited from Beijing Sport University were evaluated for measurements of body composition and bone density by dual-energy X-ray absorptiometry (DEXA). Results: Comparing to the control group, the wrestlers had higher lean mass and bone mineral mass, and the average bone density of wrestlers was greater than controls significantly, whereas body fat mass and body fat percent were lower than controls (P<0.05). In almost all parts of body (except for head), the percentage of fat composition in wrestlers was about half of that in controls. Conclusion: The characteristics of body composition and bone density in female wrestlers might be related to chronic training. The special standard of bone density for athletes might be required. Body composition and energy balance of female athletes should be paid close attention, especially for their effect on reproductive function of female athletes.
