Artistic gymnastics is one of the most demanding sports disciplines, with the athletes demonstrating extremely high levels of explosive power and strength. Currently, knowledge of the effect of gymnastic training adaptation on exercise-induced inflammatory response is limited. The study aimed to evaluate inflammatory response following lower- and upper-body high-intensity exercise in relation to the iron status in gymnasts and non-athletes. Fourteen elite male artistic gymnasts (EAG, 20.6 ± 3.3 years old) and 14 physically active men (PAM, 19.9 ± 1.0 years old) participated in the study. Venous blood samples were taken before and 5 min and 60 min after two variants of Wingate anaerobic test (WAnT), upper-body and lower-body WAnT. Basal iron metabolism (serum iron and ferritin) and acute responses of selected inflammatory response markers [interleukin (IL) 6, IL-10, and tumour necrosis factor α] were analysed. EAG performed significantly better during upper-body WAnT than PAM regarding relative mean and peak power. The increase in IL-6 levels after upper-body WAnT was higher in EAG than in PAM; the opposite was observed after lower-body WAnT. IL-10 levels were higher in EAG than in PAM, and tumour necrosis factor α levels were higher in PAM than those in EAG only after lower-body WAnT. The changes in IL-10 correlated with baseline serum iron and ferritin in PAM. Overall, gymnastic training is associated with the attenuation of iron-dependent post-exercise anti-inflammatory cytokine secretion.
竞技体操是要求最严苛的体育项目之一，运动员需展现出极高水平的爆发力和力量。目前，关于体操训练适应性对运动诱发炎症反应影响的认知有限。本研究旨在评估体操运动员和非运动员在进行上下半身高强度运动后与铁状态相关的炎症反应。14名精英男性竞技体操运动员（EAG，年龄20.6±3.3岁）和14名体力活动男性（PAM，年龄19.9±1.0岁）参与了该研究。在进行两种变式的温盖特无氧测试（WAnT），即上半身和下半身WAnT之前、之后5分钟和60分钟采集静脉血样。分析基础铁代谢（血清铁和铁蛋白）以及选定炎症反应标志物[白细胞介素（IL）6、IL-10和肿瘤坏死因子α]的急性反应。在相对平均功率和峰值功率方面，EAG在上半身WAnT期间的表现显著优于PAM。上半身WAnT后EAG的IL-6水平升高幅度高于PAM；下半身WAnT后则观察到相反情况。EAG的IL-10水平高于PAM，仅在下半身WAnT后PAM的肿瘤坏死因子α水平高于EAG。PAM中IL-10的变化与基线血清铁和铁蛋白相关。总体而言，体操训练与铁依赖性运动后抗炎细胞因子分泌的减弱有关。
