Abstract (EN): This randomized study evaluated the impact of different exercise training modalities on blood pressure and body fat responses in apparently healthy older men. Forty-eight elderly men (aged 65-75 years) were randomly assigned to an aerobic training group (ATG, n = 15), a combined aerobic and resistance training group (CTG, n = 16), or a control group (n = 17). Both exercise training programs were moderate-to-vigorous intensity, three days/week for 9-months. Strength, aerobic endurance, body fat and blood pressure were measured on five different occasions. The data were analyzed using a mixed-model ANOVA, and the independence between systolic blood pressure (SBP), diastolic blood pressure (DBP) and group was tested. A significant main effect of group (p < 0.001) was observed in strength and aerobic endurance, with higher performance observed in the CTG. A significant main effect of group (p < 0.001) and time (p = 0.029) was observed in body fat percentage, with a 2.3% decrease in CTG. A significant main effect of time was observed in SBP (p = 0.005) and in DBP (p = 0.011) for both ATG and CTG. Mean decreases in SBP and DBP, respectively, were 15 and 6 mmHg for ATG and 24 and 12 mmHg for CTG. There was a significant association for SBP (p = 0.008) and DBP (p = 0.005) in the CTG, with significant individual BP profile modifications. Both exercise-training programs reduce resting blood pressure. However, only the combined exercise training was effective at reducing body fat percentage; consequently, there were larger changes in blood pressure, which result in a significant reduction in hypertensive subjects.
