The present investigation was initiated to examine the weight management practices among wrestlers participating in the NCAA Division I, II, and III wrestling tournaments. Part 1 examined the efficacy of body composition assessment between preseason (PRE) and postseason (POST). Part 2 examined rapid weight loss (RWL) during the 20 h preceding the weigh-in and the rapid weight gained (RWG) during the first day's competition.
Subjects include 811 competitors from Divisions I, II, and III participating in the NCAA national championship tournaments between 1999 and 2004. Measurements included relative body fatness (% BF) and weight (WT) on the day preceding the tournament and the evening of the first day. Minimal weight (MW) was computed with 5% BF. Retrospectively, MW, % BF, and WT from the previous fall were obtained for comparisons from NCAA records.
Part 1: WT and % BF decreased significantly PRE (WT 74.0 +/- 11.1 kg; % BF 12.3 +/- 3.4%) to POST (WT 71.5 +/- 10.4 kg; % BF 9.5 +/- 1.8%), but MW (PRE MW 68.0 +/- 9.2 kg, POST MW 67.9 +/- 9.1 kg) remained unchanged. Heavier wrestlers and Division I and II wrestlers showed the greatest changes in WT and % BF. Part 2: RWL averaged (+/- SD) 1.2 +/- 0.9 kg and relative to weight 1.7 +/- 1.2%. Division I and lighter wrestlers showed the greatest change. RWG averaged 0.9 +/- 0.8 kg, or 1.3 +/- 1.2%. RWG was greater among lighter and Division I and II wrestlers.
Minimal weight estimates PRE appear valid compared with POST. RWL and RWG are reduced significantly over previous investigations with only mat-side weigh-ins. The NCAA weight management program appears effective in reducing unhealthy weight cutting behaviors and promoting competitive equity. Efforts to institute similar programs among younger wrestlers seem warranted.
开展本次调查是为了研究参加美国大学体育协会(NCAA)一级、二级和三级摔跤锦标赛的摔跤运动员的体重管理做法。第一部分研究了赛季前(PRE)和赛季后(POST)身体成分评估的效果。第二部分研究了称重前20小时内的快速减重(RWL)以及第一天比赛期间的快速增重(RWG)。
受试者包括1999年至2004年间参加NCAA全国锦标赛的一级、二级和三级的811名参赛者。测量内容包括比赛前一天和第一天晚上的相对体脂率(%BF)和体重(WT)。用5%的体脂率计算最低体重(MW)。回顾性地从NCAA记录中获取上一年秋季的MW、%BF和WT进行比较。
第一部分:WT和%BF从PRE(WT 74.0±11.1千克;%BF 12.3±3.4%)到POST(WT 71.5±10.4千克;%BF 9.5±1.8%)显著下降,但MW(PRE MW 68.0±9.2千克,POST MW 67.9±9.1千克)保持不变。体重较重的摔跤运动员以及一级和二级摔跤运动员的WT和%BF变化最大。第二部分:RWL平均(±标准差)为1.2±0.9千克,相对于体重为1.7±1.2%。一级和体重较轻的摔跤运动员变化最大。RWG平均为0.9±0.8千克,即1.3±1.2%。体重较轻的运动员以及一级和二级摔跤运动员的RWG更大。
与POST相比,PRE时的最低体重估计似乎是有效的。与之前仅在赛场边称重的调查相比,RWL和RWG显著降低。NCAA的体重管理计划似乎有效地减少了不健康的减重行为并促进了竞争公平性。在年轻摔跤运动员中开展类似计划的努力似乎是有必要的。
