The present study compared the physiological responses to exercise, the anaerobic fitness, and the body composition of high-ability prepubescent wrestlers and normally active boys. The wrestlers (N = 15, mean age +/- S.D. = 11.3 +/- 0.30 yr) were recruited to participate in a summer wrestling camp. Their wrestling experience averaged 3.0 +/- 1.63 yr, during which time they won 78 +/- 10.5% of the matches. The comparison boys (N = 13, 10.7 +/- 0.36 yr) were volunteers from a local Boy's Club. Each subject performed a graded treadmill exercise test (Bruce protocol) and an anaerobic cycle ergometer test. Additionally, body composition was assessed using densitometry and skinfolds. There were no differences (P greater than 0.05) between the wrestlers and the comparison subjects for age or height. The wrestlers exercised for 1.5 min longer on the treadmill and obtained a higher VO2max (54.0 +/- 1.15 ml X min-1 X kg-1, P less than 0.05) than the comparison subjects (45.6 +/- 2.10 ml X min-1 X kg-1). Also, the wrestlers had higher anaerobic test scores, greater body densities, and lower subcutaneous fat totals at all sites than the normally active boys. These data indicate that the favorable fitness and body composition scores found previously for more mature wrestlers are already present in prepubescent wrestlers.
本研究比较了高能力青春期前摔跤运动员和正常活动男孩对运动的生理反应、无氧适能和身体成分。招募了摔跤运动员（N = 15，平均年龄±标准差 = 11.3±0.30岁）参加夏季摔跤训练营。他们的摔跤经验平均为3.0±1.63年，在此期间他们赢得了78±10.5%的比赛。对照组男孩（N = 13，10.7±0.36岁）是当地男孩俱乐部的志愿者。每个受试者都进行了分级跑步机运动测试（布鲁斯方案）和无氧循环测力计测试。此外，使用密度测定法和皮褶厚度评估身体成分。摔跤运动员和对照组在年龄或身高方面没有差异（P大于0.05）。与对照组受试者（45.6±2.10 ml·min⁻¹·kg⁻¹）相比，摔跤运动员在跑步机上运动的时间长1.5分钟，并且获得了更高的最大摄氧量（54.0±1.15 ml·min⁻¹·kg⁻¹，P小于0.05）。此外，与正常活动的男孩相比，摔跤运动员的无氧测试得分更高，身体密度更大，所有部位的皮下脂肪总量更低。这些数据表明，先前在更成熟的摔跤运动员中发现的良好适能和身体成分得分在青春期前的摔跤运动员中已经存在。
