The purposes were to: 1) examine the weight loss patterns in a group of high school varsity wrestlers whose teams participated in a body composition measurement@nutrition education program, and 2) test the hypothesis that wrestling at a weight below recommended Minimum Wrestling Weight (MWW) results in decreased wrestling success.
We measured skinfold thickness in 465 wrestlers at 16 schools and, using the Lohman method, determined their percent body fat. An educational program presented at each school explained the results, provided nutritional information regarding proper diet and methods of weight loss, and suggested a voluntary MWW corresponding to 5% body fat. After excluding the heavyweight wrestlers, there were 159 varsity wrestlers. At the end of the season, we noted their weight class and whether they placed in post-season state championship qualifying tournaments.
We found that 53 wrestlers (33%) wrestled below MWW. When analyzed by school, wrestlers' non-adherence to MWW ranged from 0% to 56% of all wrestlers. In the lightest four weight classes, 62% wrestled below MWW; in the middle four classes, 29%; and in the heaviest four classes, 6%. Of the 53 wrestlers below MWW, 57% placed and of the 106 above MWW, 33% placed (P < 0.01).
These results show that a substantial number of wrestlers who participate in a voluntary body fat measurement and diet education program wrestle below recommended MWW. This is particularly true at lower weight classes. Further, wrestling below MWW was associated with greater wrestling success. The current concept of MWW should not be based on wrestling performance effects.
本研究旨在：1）调查一组高中校际摔跤运动员的体重减轻模式，这些运动员所在的团队参加了身体成分测量@营养教育项目；2）检验以下假设，即低于推荐的最低摔跤体重（MWW）进行摔跤会导致摔跤成绩下降。
我们测量了16所学校465名摔跤运动员的皮褶厚度，并使用洛曼方法确定了他们的体脂百分比。在每所学校开展的一个教育项目对测量结果进行了解释，提供了有关合理饮食和减肥方法的营养信息，并建议了一个与5%体脂相对应的自愿MWW。排除重量级摔跤运动员后，有159名校际摔跤运动员。在赛季结束时，我们记录了他们的体重级别以及他们是否在赛季后赛州冠军资格赛中获得名次。
我们发现53名摔跤运动员（33%）的体重低于MWW。按学校分析时，摔跤运动员不遵守MWW的比例在所有摔跤运动员的0%至56%之间。在最轻的四个体重级别中，62%的运动员体重低于MWW；在中间的四个级别中，这一比例为29%；在最重的四个级别中，为6%。在体重低于MWW的53名摔跤运动员中，57%获得了名次，而在体重高于MWW的106名运动员中，33%获得了名次（P<0.01）。
这些结果表明，相当数量参加了自愿体脂测量和饮食教育项目的摔跤运动员的体重低于推荐的MWW。在较低体重级别尤其如此。此外，低于MWW进行摔跤与更高的摔跤成功率相关。当前MWW的概念不应基于对摔跤成绩的影响。
