The effect of HIIT workouts along with taking omega-3 on blood rheology indexes for inactive boys

Abstract

Hemorheology is the study of the flow and deformation in the blood vessels against the force and the pressures. Blood viscosity, hematocrit and red blood cell aggregation and variability are the important determinants of hemorheology. Evidence has shown that high intensity interval training (HIIT) in a growing body can be a good alternative to endurance training which leads to similar induces or even better superior physiological adaptations in healthy individuals and patient population at least compared based on doing same tasks. The purpose of this study was to investigate effect of HIIT workouts along with taking omega-3 on blood rheology indexes for inactive boys.

The statistical population of  this study was inactive male students aged 18-20 and 40 of them were selected by randomly sampling method, and were divided into four groups of 10; including composition, exercise, supplementation and control groups. The participants passed a sweep a set path of 20 meters with a maximum intensity for 30 seconds. The starting point of test was right in the middle of two determinative barriers, at a distance of 10 meters. The test included of running from the middle line toward first barrier and then passing a 20 meters path and returning toward second barrier and it repeated continuously back and forth. The participants did the exercise protocol, three sessions per week for a period of 6 weeks. The Borg scale and heart rate measure by pulse meter were used to determine the extent of activity during exercise.  Also a pilot study was conducted on one of the subjects before the study to determine the severity and implementation of the protocol. SPSS16 Software was used for data analysis, as well as using descriptive statistics to evaluate the mean and standard deviation of data variables. ANOVA and LSD tests were used to compare the mean difference between groups. The statistical significant level was p=0.05.

HIIT workouts along with taking omega-3 had no significant effect on serum albumin and total protein levels of blood (p<0.05) but it had a significant effect on serum levels of platelets, red blood cells, hemoglobin and also erythrocyte sedimentation rate, hematocrit and blood viscosity and had improved them)p<0.05).

According to the findings of this study it can be concluded that HIIT workouts along with taking omega-3 can improve some blood rheological variables that have effect on blood viscosity and prevent the diseases related to these indices. High volume of aerobic exercise requires a lot of time and HIIT workouts need a little time, therefore it can give more motivation to people to participate in physical exercises.
