背景：负重体力活动和强烈的机械刺激通过内分泌系统影响骨骼，因此，骨负荷运动影响骨密度。我们假设，体重分类的运动员，如那些练习摔跤和柔道的运动员，骨密度相对较高，因为这些活动在日常训练中对全身的影响比低影响或非影响的活动更大。目的：调查参加摔跤和柔道比赛的体重分级运动员的骨密度，并与耐力运动员和非运动员进行比较。方法：将33名18~22岁的大学生运动员按运动历史分为摔跤运动员、柔道运动员和耐力运动员三组。8名非运动员作为对照。结果：摔跤运动员和柔道运动员的全身平均骨密度高于耐力运动员和非运动员(P<；0.01)。在调整体重因素后，摔跤和柔道运动员的骨密度高于非运动员。结论：尽管赛前体重下降很快，但体重分级运动员的骨密度明显高于耐力运动员和非运动员。(C)2020年欧洲临床营养和代谢学会。爱思唯尔有限公司出版。保留所有权利。
Background: Weight-bearing physical activity and intense mechanical stimuli affect the bone through the endocrine system; hence, bone-loading sports affect bone mineral density. We hypothesized that weight-classified athletes, such as those practicing wrestling and judo, have relatively high bone mineral density because these activities have a higher impact on the entire body during daily training compared to low- or non-impact activities. We aimed to investigate the bone mineral density of weight-classified athletes (participating in wrestling and judo) to compare the parameters with those of endurance-athletes and non-athletes.Methods: Thirty-three college athletes (aged 18-22 years) were divided into three groups, wrestlers, judoka, and endurance-athletes, according to their sports history. Eight non-athletes participated as controls. Bone mineral density was determined by whole-body dual-energy X-ray absorptiometry.Results: Mean whole-body bone mineral density of wrestlers and judoka was higher than that of endurance-athletes and non-athletes (P < 0.01). The bone mineral density of athletes competing in wrestling and judo was higher than that of non-athletes when adjusted for body mass.Conclusions: The present study demonstrated that weight-classified athletes have significantly higher bone mineral density compared to endurance- and non-athletes, despite rapid weight loss before competitions.
