The purpose of this study was to investigate 1. the extent of weight gain by high school wrestlers between an evening weigh-in and the first round of wrestling the next morning and 2. the relationship between weight gain and wrestling success.
Body weights of competitors (N = 260) in a high school wrestling tournament were recorded at official weigh-in and again, about 12 h later, immediately before the first round of wrestling. Data for the heavyweight class was excluded. Weight gain (WG in kg), relative weight gain (RWG in %), and weight discrepancy between opponents (WD in kg) were calculated from data obtained at the weighings. The mean WG for all wrestlers was 1.3 kg +/- 1.1 with a range of -2.0 kg to +4.4 kg. This corresponds to RWG of 2.2 +/- 1.7% body weight.
WG in the lower weight classes was statistically larger than that seen in the highest weight classes (P < 0.05). The smallest RWG was seen in the 189-lb. class (1.1 +/- 1.9%), and the largest RWG was seen in the 112-lb. class (3.0 +/- 2.1%). Average WD between competitors was 1.7 +/- 1.5 kg (range 0-7.5 kg.). Average WD was largest in the two heaviest classes. Average WG was 1.5 +/- 1.1 kg for winners and 1.2 +/- 1.0 kg for losers. RWG was 2.4 +/- 1.8% for winners and 1.9 +/- 1.6% for losers.
The difference in WG and RWG between winners and losers was significant (P < 0.05). In 74 of the 130 bouts (57%), the heavier wrestler was successful (NS).
本研究旨在调查1. 高中摔跤运动员在晚间称重至次日上午第一轮摔跤比赛期间的体重增加程度，以及2. 体重增加与摔跤比赛胜负之间的关系。
在一场高中摔跤锦标赛中，记录了参赛选手（N = 260）在官方称重时的体重，并在约12小时后，即第一轮摔跤比赛开始前再次记录体重。重量级别的数据被排除。根据称重数据计算体重增加量（WG，单位为千克）、相对体重增加量（RWG，单位为%）以及对手之间的体重差异（WD，单位为千克）。所有摔跤运动员的平均WG为1.3千克±1.1千克，范围为-2.0千克至+4.4千克。这相当于体重的RWG为2.2%±1.7%。
较轻体重级别的WG在统计学上大于最重体重级别（P < 0.05）。最小的RWG出现在189磅级（1.1%±1.9%），最大的RWG出现在112磅级（3.0%±2.1%）。参赛选手之间的平均WD为1.7千克±1.5千克（范围为0至7.5千克）。平均WD在两个最重级别中最大。获胜者的平均WG为1.5千克±1.1千克，失败者为1.2千克±1.0千克。获胜者的RWG为2.4%±1.8%，失败者为1.9%±1.6%。
获胜者和失败者之间的WG和RWG差异显著（P < 0.05）。在130场比赛中的74场（57%）中，体重较重的摔跤运动员获胜（无显著性差异）。
