This research aimed to examine the fluctuations in body composition and Urine-Specific Gravity (U) of elite wrestlers in a high-level official wrestling competition.
Thirty-one wrestlers in the Türkiye Senior Greco-Romen Wrestling national team participated in this research. Wrestlers were divided into weight loss and non-weight loss groups, and changes in their body composition and U were measured at three different times (beginning of the camp, weigh-in, and before the competition). The duration between the beginning of the camp and the competition weigh-in time was considered as a dehydration process and the duration between the competition weigh-in time and before the competition was regarded as a rehydration process. In the data analysis, 3 × 2 repeated measures ANOVA was used.
It was determined that during the dehydration process of wrestlers who lost weight, there was a decrease of 4.02%, 2.50%, 14.62%, and 2.66% in body weight, FFM, FM, and TBW, whereas, during the rehydration process, there was a gain of 1.85%, 1.77%, 2.63%, and 1.87%, respectively. In addition, it was determined that wrestlers who lost weight had a 0.87% increase in U during the dehydration process and a 0.41% decrease in the rehydration process. The results show that wrestlers cannot regain body weight and FM lost in the hydration fluctuation during a competition, but they can regain FFM, TBW, and U. However, although it was determined that the wrestlers were statistically able to regain FFM, TBW, and U, they could not return to the levels at the beginning of the camp.
It was determined that before a high-level official wrestling competition, wrestlers still preferred weight loss practices and it was determined that they were exposed to fluctuations in their body composition and U. It is thought that this result may negatively affect the wrestlers' health and competition performance during a high-level competition.
本研究旨在调查高水平官方摔跤比赛中精英摔跤运动员身体成分和尿比重（U）的波动情况。
土耳其高级古典式摔跤国家队的31名摔跤运动员参与了本研究。摔跤运动员被分为减重组和非减重组，并在三个不同时间（训练营开始时、称重时和比赛前）测量他们的身体成分和尿比重变化。训练营开始到比赛称重时间的间隔被视为脱水过程，比赛称重时间到比赛前的间隔被视为补液过程。在数据分析中，使用了3×2重复测量方差分析。
确定在减重的摔跤运动员脱水过程中，体重、去脂体重、脂肪质量和总体水分别下降了4.02%、2.50%、14.62%和2.66%，而在补液过程中，分别增加了1.85%、1.77%、2.63%和1.87%。此外，确定减重的摔跤运动员在脱水过程中尿比重增加了0.87%，在补液过程中下降了0.41%。结果表明，摔跤运动员在比赛期间的水合波动中无法恢复失去的体重和脂肪质量，但他们可以恢复去脂体重、总体水和尿比重。然而，尽管确定摔跤运动员在统计学上能够恢复去脂体重、总体水和尿比重，但他们无法恢复到训练营开始时的水平。
确定在高水平官方摔跤比赛前，摔跤运动员仍然倾向于减重做法，并且确定他们的身体成分和尿比重会出现波动。认为这一结果可能会对摔跤运动员在高水平比赛期间的健康和比赛表现产生负面影响。
