Effect of eight weeks high intensity circuits resistance training and interval and continues ginger supplementation on the hemorheological factors of obese females

Introduction and purpose: Obesity is the effectiveness factor of blood vessels. The purpose of this study was to investigate the effect of eight weeks high intensity circuits’ resistance training and interval and continues of ginger supplementation on the levels of fibrinogen, platelets, hematocrit and hemoglobin of obese women. Materials and methods: In order to, 44 obese women (age: 30.11±6.45 years and BMI 31.60±3.99 kg/m2) were selected and randomly divided in four groups of resistance training+placebo (n=11)، resistance training+continues ginger supplementation (n=11)، resistance training+interval ginger supplementation (n=11) and resistance training (n=11). Groups of training were performed of protocol of high intensity circuits resistance training, for 8 weeks, 3 sessions per week. Supplementary groups, used capsules of containing 500 mg ginger supplement and the placebo group were similarly taking capsules containing starch daily in two meals in the morning and at night after meals in a double-blind manner. Blood samples were collected pretest and 48 hours after the last exercise session 12-hour fasting state. Paired sample t test and repeated measures of analysis of variance were used to analysis the data at significant level of P<0.05. Results: The results showed that effect of time on the research variables was significant, and the interaction effect of group and time was not significant in any of the variables, and therefore, none of the exercise and supplement interventions hadn’t significant effect on the variables of fibrinogen, platelets, hemoglobin, and hematocrit of blood. Discussion and Conclusion: There are several mechanisms related to the effect of exercise on blood and plasma viscosity. Fibrinogen binds red blood cells to each other and to the vessel wall and increases blood viscosity. It seems that performing eight weeks of circuit resistance training with interval and continuous supplementation of ginger cannot significantly change the blood fibrinogen and hemoglobin index in obese women.
