HIIT exercises are used to improve cardiovascular fitness as an alternative to traditional endurance training. One of the new models that has attracted a lot of attention and raised many questions about the adaptations of these exercises is the Blood Flow Restriction (BFR). The aim of the present study was to evaluate the effect of 4 weeks of HIIT exercise with blood flow restriction on cardiovascular fitness and inflammatory cytokines interleukin-6 in active young male students. 18 active students in Tehran with an age range of 20 to 30 years and with a regular history of sports activities were divided into three groups by available sampling: 1. Exercise with blood flow Restriction, 2. Exercise and 3. blood flow Restriction. The HIIT program consisted of one-minute running sessions with 110% Vvo2max intensity on the treadmill. The number of running sessions in the first week included 6 sessions, to which one sessions was added each week and reached 9 stages in the fourth week. The duration of each training session was approximately 15-20 minutes. Between intense training, one minute of active rest was performed by jogging at 50% Vvo2max. The subjects in the HIIT + BFR group performed the same exercise program, with the difference was that BFR bands were attached to their leg muscles during intense intermittent strokes. Blood samples were taken fasting before and after the test. Analysis of variance with repeated measures, analysis of covariance and Bonferroni post hoc test were used to determine the differences between time and research groups. According to the results of exercise along with blood flow restriction did not cause significant changes in the amount of Vo2max or vVo2max in the study groups. According to the results of statistical tests on the level of interleukin-6, it was different between groups at rest. The amount of this index in the exercise group showed a significant difference with the two groups (P <0.05). IL-6 showed a decrease in the exercise group alone. Decreased levels of inflammatory cytokine IL-6 at rest in the exercise group may indicate a relative reduction in stress levels in this group.
