Restrictive diets, forced starvation or voluntary weight loss are attracting more and more attention from scientists. Overall trends show that about 80% of combat sports athletes use specific methods of reducing body mass. Rapid weight loss could be a risk factor for kidney-related adverse outcomes. This study aimed to examine the impact of high-intensity specific training combined with rapid weight loss in the first and without rapid weight loss in the second phases on body composition and biochemical markers of kidney function.
The study was conducted on 12 male wrestlers. Kidney function markers were measured, including blood urea nitrogen, serum creatinine, uric acid and serum Cystatin-C. Alterations in analysed markers were noted in both phases of the research.
According to the data, a significant increase was noted in blood urea nitrogen (p=0.002), uric acid (p=0.000) and serum creatinine (p=0.006) during the first phase in comparison with the second phase. The levels of serum Cystatin-C were slightly elevated after both phases compared with the initial measurement.
It is evident that high-intensity specific training combined with rapid weight loss significantly affects the increase in kidney function markers compared with identical training without rapid weight loss. The findings in this study suggest that rapid body mass reduction is associated with an increased risk of acute kidney injury in wrestlers.
限制性饮食、强制饥饿或自愿减重正吸引着越来越多科学家的关注。总体趋势表明，约80%的格斗运动运动员采用特定的减重方法。快速减重可能是肾脏相关不良后果的一个风险因素。本研究旨在探讨第一阶段高强度特定训练结合快速减重以及第二阶段不进行快速减重对身体成分和肾脏功能生化指标的影响。
该研究针对12名男性摔跤运动员开展。测量了肾功能指标，包括血尿素氮、血清肌酐、尿酸和血清胱抑素-C。在研究的两个阶段均记录了分析指标的变化。
根据数据，与第二阶段相比，第一阶段血尿素氮（p=0.002）、尿酸（p=0.000）和血清肌酐（p=0.006）显著升高。与初始测量相比，两个阶段后血清胱抑素-C水平均略有升高。
显然，与不进行快速减重的相同训练相比，高强度特定训练结合快速减重会显著影响肾功能指标的升高。本研究结果表明，快速减重与摔跤运动员急性肾损伤风险增加有关。
