Introduction: The aim of this study was to compare the response of blood pressure and arterial stiffness to different high-intensity training methods.
Materials and Methods: twenty-six prehypertensive men aged 25-45 years categorized in 4 groups: aerobic, resistance and combined exercise. Pre and post Blood pressure and arterial stiffness measurements were performed. Paired sample t-test was used to compare within-group and multivariate analysis of covariance (Mancova) test was used to compare between-group differences.
Results: The results showed that diastolic blood pressure was significantly reduced in the aerobic group (P=0.012) but was insignificant in the resistance group (P=0.297) and combined (P=0.102). Aerobic (P=0.005) and combined exercise (p < 0.001) significantly reduced systolic blood pressure, but in the resistance group (P=0.178) was not significant. Arterial stiffness of the aerobic (P=0.001) and combined (P=0.015) groups was significantly reduced but was not significant in the resistance group (P=0.168). Between groups comparison showed that the diastolic blood pressure of the aerobic group experienced significance reduction than other groups. Also, post-test Systolic blood pressure in both aerobic and combined groups were significantly different from the resistance and control groups. In arterial stiffness, there was a significant difference between the aerobic group and control and resistance groups, as well as the combined and control groups.
Conclusion: In general, aerobic exercise showed that it has beneficial effects on all variables, but in resistance training, little effect was seen. An important finding is that combined exercises, which are being increasingly popular these days, can have the same positive effects as aerobic exercise.
