Compare the Effects of Two High Intense Interval Training (HIIT) Protocol on Some Hem Rheological Markers in Young Overweight and Obese Women
Abstract
Background: Manipulation of training variables such as intensity, volume and training session’s frequency could affect the exercise compatibility and dynamicity these carry out different physiological adaptations. The purpose of this study is determining the effect of two types high intensity training (HIIT) on some hem rheological factors in young overweight and obese women. Methods: 24 girls with age 25/75±1/18 y, height: 161/29± 4/23cm, weight 74/51±6/27 kg, fat 30/70± 2/23%, BMI 28/66±1/89 kg/m2 voluntarily participated in this study and randomly divided into three experimental HIIT1 group (n=8), HIIT2 group (n=8) and control group (n=8). The subjects of the group HIIT1 in each session running 30 seconds in four sets with 19 to 20 the rate of perceived exertion (RPE) Borg scale and two minutes of rest between sets. HIIT2 group running four sets of 60 s with the same intensity and four minutes rest between sets, training protocol performed three times a week and as long as four weeks. 48 hours before and 48 hours after exercise, blood samples were taken. For analyzing data, use Mixed between-within Subjects analysis of variance in level of (p>0.05). Results: Results showed in levels of RBC , MCV, MCH , hematocrit, hemoglobin wasn’t significantly variation and also difference between groups was not significant (p>0.05). RDW was significantly changed only in HIIT2 group (p0.05). MCHC in each the experimental groups showed significantly changes, the difference between groups was significant only between each experimental groups with control (p<0.01). Conclusion: according to the results, it can be said that short term HIIT (30 s) in comparison with midterm HIIT (60 s) probably accompanied with slightly hemolysis side effects.
