BACKGROUND: A family history of arterial hypertension is a significant risk factor for the development of hypertension in youngsters. Thus, primary prevention has been emphasized in those subjects with a genetic predisposition.
METHODS: This randomized clustered trial aimed to compare the effects of four modalities of aerobic training in postexercise hypotension. The primary outcomes were systolic blood pressure (SBP) and diastolic blood pressure (DBP). Secondly, peak oxygen uptake, heart rate, and subjective perceived exertion were analyzed. Nine normotensive men were randomized in four isocaloric sessions (200 kcal): high-intensity continuous training (HICT), moderate-intensity continuous training (MICT), high-intensity interval training (HIIT), and moderate-intensity interval training (MIIT).
RESULTS: The area under the curve (AUC) showed a difference between sessions for SBP (F(3;8)=3.2; P=0.04), with MICT promoting a higher reduction than MIIT (P<0.05). In DBP there was also a difference (F(3;8)=15.3; P<0.001), with HICT reducing more than HIIT (P<0.05) and MIIT (P<0.05). Moderate-intensity protocols provided clinically relevant changes (CRC) in 11.1% of the individuals, and high-intensity protocols presented CRC in 50% of them (χ²=6.41; P=0.011) for SBP. For DBP, there was CRC in 27.8% of continuous conditions and none in the intervals (χ²=5.81; P=0.016).
CONCLUSIONS: All training sessions promoted postexercise hypotension for DBP, and HICT provided higher reductions in the AUC. CRC for SBP were observed according to the intensity, while CRC for DBP were associated with modality.
