BACKGROUND Isokinetic exercise is used to reduce strength imbalance and to enhance performance. OBJECTIVE The aim of this study was to investigate the acute effects of a single bout of eccentric isokinetic exercise on hemorheology (erythrocyte deformability and aggregation), total oxidant/antioxidant status (TOS/TAS) and oxidative stress index (OSI) in active individuals. METHODS The study comprises 11 active, healthy, male subjects (mean age of 19.45 ± 0.31 years, BMI 22.05 ± 0.51 kg/m2). They performed single, unilateral eccentric contractions of knee flexors and extensors with dominant leg on a dynamometer. Isokinetic hamstring, quadriceps strength were recorded at eccentric (30, 120° s-1) angular velocities. Eight active age-matched healthy male subjects were included as a control group, who did not receive exercise. Blood samples were obtained before, immediately after and two days after the exercise session. Hemorheological parameters were measured by an ektacytometer. TOS/TAS were determined using a commercial kit. RESULTS A session of eccentric isokinetic exercise did not affect erythrocyte deformability and oxidative stress indices, whereas red blood cell (RBC) aggregation was increased initially and returned to pre-exercise levels after two days following exercise. CONCLUSION Our results suggest that, increased RBC aggregation following an acute bout of isokinetic exercise may result in increased plasma skimming that augments tissue perfusion and clearance of metabolites within a period of two days following exercise.

急性离心运动后,红细胞聚集增加不超过两天。

背景技术等速运动用于减少力量失衡并增强表现。目的本研究的目的是研究单次偏心等速运动对活跃个体的血液流变学(红细胞变形性和聚集性),总氧化剂/抗氧化剂状态(TOS / TAS)和氧化应激指数(OSI)的急性影响。方法该研究包括11名活跃,健康的男性受试者(平均年龄为19.45±0.31岁,BMI为22.05±0.51 kg / m2)。他们用测力计对膝盖屈伸肌进行单侧偏心收缩。等速肌腱绳肌,股四头肌的强度在偏心(30,120°s-1)角速度下记录。八名年龄匹配的健康男性受试者作为对照组,他们没有运动。在运动前,运动后和运动后两天采集血样。用流式细胞仪测定血液流变学参数。TOS / TAS使用市售试剂盒测定。结果进行一轮离心运动并不影响红细胞的变形能力和氧化应激指数,而红细胞(RBC)的聚集最初增加,运动后两天恢复到运动前的水平。结论我们的研究结果表明,在等速运动后,红细胞聚集增加可能导致血浆撇脂增加,从而在运动后两天内增加组织灌注和代谢产物清除率。TOS / TAS使用市售试剂盒测定。结果进行一轮离心运动并不影响红细胞的变形能力和氧化应激指数,而红细胞(RBC)的聚集最初增加,运动后两天恢复到运动前的水平。结论我们的研究结果表明,在等速运动后,红细胞聚集增加可能导致血浆撇脂增加,从而在运动后两天内增加组织灌注和代谢产物清除率。TOS / TAS使用市售试剂盒测定。结果进行一轮离心运动并不影响红细胞的变形能力和氧化应激指数,而红细胞(RBC)的聚集最初增加,运动后两天恢复到运动前的水平。结论我们的研究结果表明,在等速运动后,红细胞聚集增加可能导致血浆撇脂增加,从而在运动后两天内增加组织灌注和代谢产物清除率。运动后两天,红细胞(RBC)的聚集开始增加,并恢复到运动前的水平。结论我们的研究结果表明,在等速运动后,红细胞聚集增加可能导致血浆撇脂增加,从而在运动后两天内增加组织灌注和代谢产物清除率。运动后两天,红细胞(RBC)的聚集开始增加,并恢复到运动前的水平。结论我们的研究结果表明,在等速运动后,红细胞聚集增加可能导致血浆撇脂增加,从而在运动后两天内增加组织灌注和代谢产物清除率。
