Acute hemorheological responses to different types of aerobic exercises have never been compared in a single study in healthy people.
We aimed to compare acute effects of high intensity intermittent exercise (HIIE) and moderate intensity continuous exercise (MICE) on hemorheological parameters, in healthy young subjects.
A total of 34 sedentary young adults (12 males, 22 females) with a mean age of 20.0 ± 2.1 years were randomly assigned to HIIE, MICE or non-exercise groups. MICE exercised at the power corresponding to 50% of heart rate reserve (HRR) continuously for 25 min. HIIE exercised at the power corresponding to 100% of HRR for 30 s followed by 30 s rest for 25 min. The non-exercise group rested. Blood samples were collected before and after exercise and studied for blood count, whole blood viscosity (WBV), plasma viscosity (PV) and red blood cell (RBC) elongation at nine different shear stresses.
WBV, PV, RBC elongation of MICE and HIIE groups were not found to be statistically different from each other or from the non-exercise group. Compared to the non-exercise group, there was a significant increase in white blood cell (WBC) and RBC counts in the MICE group.
Different types of aerobic exercises, namely MICE, HIIE are not different from each other in terms of hemorheological parameters immediately after exercise.
在一项针对健康人的研究中,从未对不同类型有氧运动的急性血液流变学反应进行过比较。
我们旨在比较高强度间歇运动(HIIE)和中等强度持续运动(MICE)对健康年轻受试者血液流变学参数的急性影响。
总共34名久坐不动的年轻成年人(12名男性,22名女性),平均年龄为20.0±2.1岁,被随机分配到HIIE组、MICE组或非运动组。MICE组以相当于心率储备(HRR)50%的功率持续运动25分钟。HIIE组以相当于HRR 100%的功率运动30秒,然后休息30秒,共进行25分钟。非运动组进行休息。在运动前后采集血样,研究血细胞计数、全血粘度(WBV)、血浆粘度(PV)以及在九种不同切变应力下的红细胞(RBC)伸长情况。
未发现MICE组和HIIE组的WBV、PV、RBC伸长与非运动组之间存在统计学差异。与非运动组相比,MICE组的白细胞(WBC)和红细胞计数显著增加。
就运动后即刻的血液流变学参数而言,不同类型的有氧运动,即MICE和HIIE,彼此之间没有差异。
