Body composition and physical dimensions were compared between 23 young, experienced wrestlers (mean age +/- SE = 11.0 +/- 0.21 yr) and 23 school children (11.2 +/- 0.24 yr). The wrestlers were among the best wrestlers from local wrestling clubs and averaged 2.7 (+/- 0.27) yr of experience. They had won 72% (+/- 1.8%) of the total 75 (+/- 9.1) matches. The comparison group consisted of volunteers from local elementary schools. Standard densitometric and anthropometric techniques were used to measure the body composition and physical dimensions of each group. The wrestlers were 4 kg lighter (P less than 0.05) and had a smaller percent fat than the comparison group (13.3 +/- 0.66% and 20.0 +/- 1.13%, respectively). The weight difference between groups was due to the larger fat weight of the comparison group since lean weight differed by only 0.8 kg. Fat differences were also reflected in the larger skinfolds and "fat" circumferences of the comparison group. No group differences were noted in diameters. It is concluded that compared to other children young experienced wrestlers have similar skeletal structures and lean body weights. The comparison group possessed more body fat.
对23名年轻且经验丰富的摔跤运动员（平均年龄±标准误=11.0±0.21岁）和23名学童（11.2±0.24岁）的身体成分和身体尺寸进行了比较。这些摔跤运动员是当地摔跤俱乐部中最优秀的一批，平均有2.7（±0.27）年的摔跤经验。在总共75（±9.1）场比赛中，他们赢得了72%（±1.8%）。对照组由当地小学的志愿者组成。使用标准的密度测量和人体测量技术来测量每组的身体成分和身体尺寸。与对照组相比，摔跤运动员轻4千克（P<0.05），体脂百分比更低（分别为13.3±0.66%和20.0±1.13%）。两组之间的体重差异是由于对照组的脂肪重量更大，因为瘦体重仅相差0.8千克。脂肪差异也反映在对照组更大的皮褶厚度和“脂肪”周长上。在直径方面未发现组间差异。得出的结论是，与其他儿童相比，年轻的有经验的摔跤运动员具有相似的骨骼结构和瘦体重。对照组的体脂更多。
