Weight loss practice before competitions is a common method in weight sports.
The current study aimed to monitor Plasma Osmolarity (POsm), skeletal muscle damage and inflammation levels induced by pre-competition dehydration among elite wrestlers.
Twenty-four male elite wrestlers participated in the study. A survey information form that assessed pre-competition weight loss practices were administered to the wrestlers. Additionally, Total Creatine Kinase (CK), Lactate Dehydrogenase (LDH), Aspartate Aminotransferase (AST), Alanine Aminotransferase (ALT), C-reactive Protein (C-RP) and POsm, analyses were evaluated by a specialist at the biochemical laboratory. POsm level for euhydration is ⩽ 290 mOsm/L. But if POsm level is > 290, then dehydration occurs. The wrestlers were divided into two groups according to POsm levels as weight loss and non-weight loss group.
There were differences in the pre and post-test POsm levels of weight loss group. Similarly; it was identified that there were also statistically significant differences in terms of ALT, LDH and CK levels of weight loss group between pre and post-test.
It was seen that POsm and levels of all indicators of skeletal muscle damage were higher than non-weight loss group. However, it was found that there were not any differences in terms of C-RP levels.
赛前减重是举重项目中常用的方法。
本研究旨在监测精英摔跤运动员赛前脱水引起的血浆渗透压(POsm)、骨骼肌损伤和炎症水平。
24名男性精英摔跤运动员参与了本研究。向摔跤运动员发放了一份评估赛前减重做法的调查问卷。此外,总肌酸激酶(CK)、乳酸脱氢酶(LDH)、天冬氨酸转氨酶(AST)、丙氨酸转氨酶(ALT)、C反应蛋白(C-RP)和POsm的分析由生化实验室的一名专家进行评估。正常水合状态下的POsm水平≤290 mOsm/L。但如果POsm水平>290,则发生脱水。根据POsm水平,摔跤运动员被分为减重组和非减重组。
减重组测试前后的POsm水平存在差异。同样,减重组测试前后的ALT、LDH和CK水平在统计学上也存在显著差异。
发现POsm和所有骨骼肌损伤指标水平均高于非减重组。然而,发现C-RP水平没有差异。
