PURPOSE: To assess hemodynamic and cardiac autonomic response to high-intensity interval exercise (HIIE) versus moderate-intensity continuous exercise (MICE) in individuals with Parkinson's disease (PD).
METHODS: 12 individuals (six men) with PD were randomly assigned to perform HIIE (4 min of warm-up followed by 21 min alternating 1 min at levels 15-17 with 2 min at levels 9-11 of rating of perceived exertion [RPE] in a cycle ergometer), MICE (4 min of warm-up followed by 26 min at levels 11-14 of RPE in a cycle ergometer) and control (CON; 30 min of sitting rest) interventions in separate days. Heart rate (HR), blood pressure (BP), endothelial reactivity and heart rate variability (HRV) were assessed before, immediately after and 45 min after each intervention. HR and exercise workload were measured during each intervention.
RESULTS: Despite the within (high- vs. low-intensity intervals of HIIE) and between (HIIE vs. MICE) differences in workload during exercise sessions, HR was not different between high- (average HR = 98±18 bpm) and low-intensity (average HR 97±19 bpm) intervals of HIIE, as well as between HIIE (average HR = 97±18 bpm) and MICE (average HR = 93±19 bpm) throughout the exercise. There were significant, but small, increases (P < 0.01) in HR and systolic BP at post HIIE and MICE, which returned to levels similar to pre-intervention during recovery. There were no within- and betweenintervention differences in diastolic BP, endothelial reactivity and HRV.
CONCLUSIONS: The present results suggest that hemodynamic response to exercise is impaired in individuals with PD.
