Abstract :

Background and aims: Aerobic training are interventions based on cardiac rehabilitation in heart failure. The aim of the present study was to comparison of the effect of Interval and continuous aerobic training with inspiratory resistance training on apelin 17 and the renin-angiotensin system in men with heart failure.Materials and Methods: In this semi-experimental research, 30 men with heart failure were randomly divided into 3 groups of intermittent aerobic exercise, continuous aerobic exercise and control. The training intervention consisted of eight weeks of continue or interval aerobic training in two 10-minute section on a treadmill or ergometers with an intensity of 40-85% of the reserve heart rate, followed by inspiratory resistance training with an intensity of 40-70% S-index. Both exercise protocols were isocaloric and only the method of aerobic exercise was different in the two groups. Analysis of covariance test was used for statistical analysis (P ≥ 0.05).Results: After eight weeks of training, there was a significant decrease in angiotensin I (P < 0.001) and a significant increase in angiotensin II levels (respectively: P = 0.019; P = 0.013) and apelin 17 (P < 0.001) were observed in the continuous and interval training groups compared to the control group. Also, no significant difference was observed between the two continuous and periodic training groups.Conclusion: According to the results, it can be said that continue or interval aerobic training, has positive effects on the renin-angiotensin system by increasing apelin and thus improving cardiovascular function in patients with heart failure.
