A 2000-m exercise test on a rowing ergometer is intended to determine the training program's effectiveness and the proper training intensity. However, anecdotal data from rowers confirm that this test involves extremely high levels of exercise, which may induce metabolic stress. Therefore, this observational study aims to analyze the effects of a 2000-m exercise test on biomarkers of inflammation, oxidative stress, and the immune system during the preparation phase in elite rowers.
The Polish Youth National Rowing Team participated in the study (N = 18). The rowers performed a 2000-m exercise test on a rowing ergometer. Before the exercise test, after one and 24 h afterwards, venous blood was taken to determine biomarkers. Pro-oxidant-antioxidant balance parameters (total antioxidant capacity, thiobarbituric acid reactive substances), pro- and anti-inflammatory cytokine levels (IL-2, IL-10, TNF-α, IL-6), and MYO were determined. This is part of a study that has been registered on clinicaltrials.gov under the identifier NCT06133751.
A statistically significant increase in IL-6 concentrations was observed 24 h after exercise. IL-10 concentrations statistically decreased significantly immediately after and 24 h post exercise. MYO levels statistically decreased significantly immediately after and 24 h post exercise. WBC statistically increased significantly immediately after exercise and then returned to baseline values.
The results of this study confirm that the 2000-m exercise test causes short-term inflammation, which is related to the physiological recovery process. In addition, chronic inflammation and immune system disturbances were not observed, which means that the athletes showed adaptation to very intense exercise.
在划船测功仪上进行的2000米运动测试旨在确定训练计划的有效性和适当的训练强度。然而,来自划船运动员的轶事数据证实,该测试涉及极高强度的运动,这可能会引发代谢应激。因此,这项观察性研究旨在分析2000米运动测试对精英划船运动员准备阶段炎症、氧化应激和免疫系统生物标志物的影响。
波兰青年国家划船队参与了该研究(N = 18)。运动员们在划船测功仪上进行了2000米运动测试。在运动测试前、运动后1小时和24小时,采集静脉血以测定生物标志物。测定了促氧化剂-抗氧化剂平衡参数(总抗氧化能力、硫代巴比妥酸反应性物质)、促炎和抗炎细胞因子水平(IL-2、IL-10、TNF-α、IL-6)以及肌红蛋白(MYO)。这是一项已在clinicaltrials.gov上注册的研究的一部分,标识符为NCT06133751。
运动后24小时观察到IL-6浓度有统计学意义的升高。运动后即刻和24小时,IL-10浓度有统计学意义的显著下降。运动后即刻和24小时,MYO水平有统计学意义的显著下降。运动后即刻白细胞(WBC)有统计学意义的显著升高,然后恢复到基线值。
本研究结果证实,2000米运动测试会引发短期炎症,这与生理恢复过程有关。此外,未观察到慢性炎症和免疫系统紊乱,这意味着运动员对非常高强度的运动表现出了适应性。
