Abstract：
Energy imbalance exposes athletes to relative energy deficiency in sports (REDs) syndrome. Data on energy consumption, REDs, and bone mineral density (BMD) in adolescent acrobatic gymnasts, especially in males, are scarce. Our aim was to examine the eating habits, energy balance, body composition, and BMD of these athletes. In this study, 18 healthy adolescents participating in competitive acrobatic gymnastics completed a questionnaire, underwent a dual-energy X-ray absorptiometry scan (DXA), received a food log, and had their activities monitored for 3 days. Eighteen acrobats were enrolled (mean age: 14.3 ± 1.2 years; males: 6/18). The mean total body BMD Z-score was 0.4 ± 1.0. Top-position acrobats (7/18) had significantly lower total body BMD Z-scores than base-positioned acrobats (-0.2 ± 0.3 vs. 0.8 ± 0.3, p = 0.032), though their forearms were not significantly different (0.2 ± 0.5 vs. 0.8 ± 0.7, p = 0.331). No sex differences were found for BMD Z-scores, BMI, or energy availability. The BMD parameters of the acrobats were within the normal range for a healthy pediatric population, although three had low BMDs (<-1 SD) for healthy athletes. Total body and LS BMD Z-scores were significantly lower in top-position athletes compared to base-position athletes. These findings suggest personalized (top vs. base) training programs (high-impact training) that may achieve better health outcomes.
摘要：
能量失衡使运动员面临运动中相对能量不足（REDs）综合征。能源消耗数据，REDs,青少年杂技体操运动员的骨密度（BMD），尤其是男性，是稀缺的。我们的目的是检查饮食习惯，能量平衡,身体成分,和这些运动员的骨密度。在这项研究中,18名参加竞技杂技体操的健康青少年填写了一份问卷，进行了双能X射线吸收扫描（DXA），收到了一份食物日志，并对他们的活动进行了3天的监控。招募了18名杂技演员（平均年龄：14.3±1.2岁；男性：6/18）。平均全身BMDZ评分为0.4±1.0。顶级杂技演员（7/18）的全身BMDZ评分明显低于基础杂技演员（-0.2±0.3vs.0.8±0.3，p=0.032），尽管他们的前臂没有显着差异（0.2±0.5vs.0.8±0.7，p=0.331）。BMDZ评分没有性别差异，BMI,或能源可用性。对于健康的儿科人群，杂技演员的BMD参数在正常范围内，尽管三个健康运动员的BMD较低（<-1SD）。与基础位置运动员相比，顶级运动员的总体身体和LSBMDZ得分明显较低。这些发现表明个性化（顶部与基地)培训计划(高影响力培训)，可以实现更好的健康结果。
