Abstract

The aim of this article is to review current literature on the response of soluble interleukin-6 receptor to exercise and identify a potential role for sIL-6R in skeletal muscle function. We also provide novel data on the impact of eccentric exercise on circulating levels. The aim of the research study was to investigate changes in plasma concentration of soluble interleukin-6 receptor (sIL-6R) and soluble glycoprotein 130 (sgp130) during recovery from exercise-induced muscle damage (EIMD) up to 72 h and their relationship with delayed onset muscle soreness (DOMS) and muscle function. 18 participants attended the laboratory on 4 consecutive days. On the first day, participants completed 6 sets of 10 repetitions of unilateral eccentric-concentric knee flexions at a test speed of 1.05 rad.s(-1) using a Cybex Isokentic dynamometer to induce muscle damage of the hamstrings. Prior to the eccentric exercise bout and each subsequent morning, following an overnight fast, participants had a venous blood sample taken which was centrifuged immediately and plasma frozen at -80 degrees C until later analysis. Plasma IL-6 and sgp130 were unchanged at any time point during recovery but sIL-6R was significantly reduced at 48 h and 72 h post-exercise (p < 0.05). Plasma sIL-6R was correlated with DOMS at 48 h post EIMD (r = 0.45, p < 0.05) and peak muscle torque at 24 h and 48 h following EIMD (r = -.42; p < 0.05; r = -.57; p < 0.01 respectively). Our novel finding that sIL-6R concentrations are decreased 2-3 days following a single bout of EIMD may reflect a regulatory mechanism controlling the influx of different leukocyte subpopulations into damaged tissue, although this needs to be confirmed by future studies. Our data suggests an association between sIL-6R, perception of pain and reduced peak muscle performance post-EIMD but further investigation is warranted to explore this relationship and implications for exercise performance.

运动对血浆可溶性IL-6受体浓度的影响:一种二元反应。
本文的目的是回顾目前关于可溶性白介素-6受体对运动的反应的文献,并确定sIL-6R在骨骼肌功能中的潜在作用。我们还提供了关于偏心运动对循环水平影响的新数据。本研究的目的是研究运动性肌肉损伤(EIMD)恢复72小时内血浆可溶性白细胞介素-6受体(sIL-6R)和可溶性糖蛋白130 (sgp130)浓度的变化及其与迟发性肌肉酸痛(DOMS)和肌肉功能的关系。18名参与者连续4天进入实验室。在第一天,参与者使用Cybex等量肌力计以1.05 rad.s(-1)的测试速度完成6组10次的单侧偏心-同心膝关节屈曲,以诱导腘绳肌的肌肉损伤。在离心运动之前和随后的每个早晨,在禁食一夜之后,参与者都要采集静脉血样本,并立即离心,血浆在-80摄氏度下冷冻,以供以后分析。血浆IL-6和sgp130在恢复期间的任何时间点不变,但sIL-6R在运动后48 h和72 h显著降低(p < 0.05)。血浆sIL-6R与EIMD后48 h迟发性肌肉酸痛相关(r = 0.45, p < 0.05),与EIMD后24 h和48 h肌肉扭矩峰值相关(r = - 0.42;P < 0.05;R = - 0.57;P < 0.01)。我们的新发现是,单次EIMD发作后2-3天sIL-6R浓度降低,这可能反映了一种控制不同白细胞亚群涌入受损组织的调节机制,尽管这需要未来的研究证实。我们的数据表明sIL-6R、疼痛感知和eimd后肌肉峰值性能降低之间存在关联,但需要进一步研究以探索这种关系及其对运动表现的影响。

期刊介绍: Exercise Immunology Review (EIR) serves as the official publication of the International Society of Exercise and Immunology and the German Society of Sports Medicine and Prevention. It is dedicated to advancing knowledge in all areas of immunology relevant to acute exercise and regular physical activity. EIR publishes review articles and papers containing new, original data along with extensive review-like discussions. Recognizing the diverse disciplines contributing to the understanding of immune function, the journal adopts an interdisciplinary approach, facilitating the dissemination of research findings from fields such as exercise sciences, medicine, immunology, physiology, behavioral science, endocrinology, pharmacology, and psychology.
