Daily Movement Matters: Post-Exercise Hypotension in Peripheral Arterial Disease—A Quasi-Experimental Pilot Study

<b>Background</b>: Aerobic and resistance training have acute effects on blood pressure (BP) in peripheral arterial disease (PAD). However, the combined effect of both exercises in a single session is still unknown. The aim of this study was to analyze the effects of a single exercise session combining walking and circuit-based training on BP in patients with PAD. <b>Methods</b>: Participants with PAD (n = 13; 65.0 ± 10.2 years; 76.9% male) underwent a supervised exercise therapy (SET) intervention (312 sessions, 24 sessions/patient) that included 15-30 min of walking, followed by 15 min circuit-based training. Clinic systolic (SBP) and diastolic (DBP) were recorded 5 min before and after each exercise session. Longitudinal changes were analyzed using repeated-measures analysis of variance (ANOVA) and categorical changes in blood pressure levels were evaluated with chi-square tests. <b>Results</b>: After each exercise session, clinic SBP decreased 4.87 mmHg (<i>p</i> < 0.001) and clinic DBP decreased 2.11 mmHg (<i>p</i> < 0.001). Furthermore, there were no differences between the initial stage of training (1-10 sessions) and late (14-24 sessions) for each time that SBD or DBP were measured. <b>Conclusions</b>: After an acute exercise session, both clinical SBP and DBP decreased in patients with PAD compared to pre-exercise values. However, no additional reductions in clinical BP were observed when comparing early (sessions 1-10) and late (sessions 14-24) stages of the full SET intervention.
