Abstract: PURPOSE: To assess the effect of high-intensity interval training (HIIT) versus continuous moderate exercise training (CME) on hemodynamic and functional variables in subjects with Parkinson disease (PD). METHODS: 20 subjects (13/7 men/women) with PD were randomly assigned to a twice-weekly HIIT (N = 12) or CME (N = 8) for 12 weeks, and have their hemodynamic (resting heart rate and blood pressure, carotid femoral pulse wave velocity, endothelial reactivity and heart rate variability) and functional variables (5-time seat-to-stand (STS), timed-up and go and 6 min walking test (6MWT)) assessed before and after training period. Exercise training intensity was regulated by the 6-20 rating of perceived exertion scale (RPE), and consisted of 25 min of HIIT (4 min walking warm-up at 9-11 RPE level, followed by 21 min alternating 1 min of briskly walking/jogging/running at 15-17 RPE level with walking at 9-11 RPE level) or 30 min of CME (4 min walking warm-up at 9-11 RPE level, followed by 26 min of walking/jogging at 11-13 RPE level). RESULTS: No significant differences between HIIT and CME were found in all variables at baseline. Endothelial reactivity tended to increase after HIIT, but not after CME, which result in improved level (~8%, P < 0.01) of this variable in HIIT versus CME during follow-up. 6MWT improved (10.4 ± 3.8 %, P < 0.05) after HIIT, but did not changed after CME. STS improved similarly after HIIT (27.2 ± 6.1 %, P < 0.05) and CME (21.5 ± 5.4 %, P < 0.05). No significant changes were found after HIIT or CME in any other variable assessed. CONCLUSION: There was different adaptation to HIIT versus CME in endothelial reactivity and 6MWT, but not in the other assessed variables. The present results suggest that exercise intensity may influence the training-induced adaptation on endothelial reactivity and walking capacity in PD patients
