Abstract

The pleiotropic cytokine interleukin-6 (IL-6) has been demonstrated to increase during exercise. Little is known regarding the response of the soluble IL-6 receptors (sIL-6R and sgp130) during such exercise. The aim of the current study was to investigate the response of plasma IL-6, sIL-6R and sgp130 during fatiguing submaximal exercise in humans. Twelve participants underwent an incremental exercise test to exhaustion and one week later performed a submaximal exercise bout (96 +/- 6% lactate threshold) to volitional exhaustion. Blood samples taken at rest and immediately post exercise were analyzed for IL-6, sIL-6R and sgp130. IL-6 increased (P < 0.01) by 8.4 +/- 8.9 pg ml(-1) (75.7%) during the exercise period. sIL-6R and sgp130 also increased (P < 0.05) by 2.7 +/- 3.9 ng ml(-1) (9.6%) and 37.7 +/- 55.6 ng ml(-1) (9.6%), respectively. The current study is the first investigation to demonstrate that alongside IL-6, acute exercise stress results in an increase in both sIL-6R and sgp130.

摘要

多效细胞因子白细胞介素-6(IL-6)已被证明在运动过程中会增加。关于可溶性IL-6受体(sIL-6R和sgp130)在这种运动中的反应知之甚少。本研究的目的是调查人体在疲劳性次最大运动期间血浆IL-6、sIL-6R和sgp130的反应。12名参与者进行了递增运动测试直至力竭,一周后进行了一次次最大运动(乳酸阈值的96±6%)直至自愿力竭。在休息时和运动后立即采集血样,分析其中的IL-6、sIL-6R和sgp130。运动期间IL-6增加了(P<0.01)8.4±8.9 pg ml-1(75.7%)。sIL-6R和sgp130也分别增加了(P<0.05)2.7±3.9 ng ml-1(9.6%)和37.7±55.6 ng ml-1(9.6%)。本研究是首次证明除IL-6外,急性运动应激会导致sIL-6R和sgp130均增加的调查。
