SUMMARY:

Introduction:
Hypertension (HT) affects two out of every three elderly individuals in Brazil. Physical exercise is part of the non-pharmacological treatment for HT. Recently, high-intensity interval training (HIIT) has been considered for individuals with HT. Although the antihypertensive effects of HIIT are well-established in the medium and long term (>12 weeks), its short-term effects remain unclear.

Objective:
To investigate the short-term effects of low-volume HIIT on blood pressure and arterial stiffness in elderly individuals with HT.

Method:
This is a pilot randomized clinical trial. A total of 32 participants (age: 66 ± 4 years; HT diagnosis: 14 ± 9 years) were randomized into: i) HIIT (n = 14); ii) control (n = 18). The HIIT was performed three times a week for six weeks, consisting of 4-8 one-minute intervals (perceived exertion 7-8) with one minute of active recovery (perceived exertion 3-4). The control group participated in weekly health education meetings. Ambulatory blood pressure (24 hours, awake, and sleep) and resting blood pressure (central and peripheral), as well as arterial stiffness (aortic pulse wave velocity; central augmentation index - AIx) were measured before and after six weeks in both groups. The generalized estimating equations model was used for data analysis.

Results:
No time × group interaction was observed in the analyzed variables (p < 0.05). Post hoc analysis revealed a time effect, with a reduction in peripheral systolic blood pressure (121 ± 4 vs. 116 ± 3 mmHg; p < 0.01) and AIx (27.7 ± 2.2 vs. 23.1 ± 2.5; p < 0.05) in the HIIT group.

Conclusion:
Our preliminary data suggest that six weeks of low-volume HIIT has limited antihypertensive effects in elderly individuals with HT.
