The effect of a high-intensity interval training on some of factors affecting erythrocyte sedimentation rate in sedentary young men

There is inverse relationship between physical activity and inflammatory biomarkers; so the aim of this study was to investigate the effect of a high intensity interval training course on erythrocyte sedimentation rate of sedentary young men. For this purpose, 18 sedentary male (age=23.80±1.71 years, height=178.22±5.89 cm, weight=74.27±6.91 kg) were voluntarily chosen and randomly divided into training and control groups. The training group performed high intensity interval training (high 90 percent) for 6 weeks and 3 sessions per week. The hematocrit, hemoglobin and red blood cells and erythrocyte sedimentation rate were measured by flow cytometry and Westergren method respectively, before and after 6 weeks of high intensity interval training from all subjects, in the fasting state. The dependent t test and independent t- test were used to analyze the data of study at p< 0.05. The results of this study showed that six weeks of high intensity interval training reduce the significantly erythrocyte sedimentation rate (p=0.004), body fat (p=0.01), plasma hematocrit (p= 0.002), plasma hemoglobin (p=0.001) and plasma red blood cell count (p = 0.001) and increase the volume of plasma in the training group. The results suggest that the high intensity interval training could be considered as a important factor to improve blood variables associated with the reduction of risk of cardiovascular disease in sedentary young men.
