The Effect of Chronotropic Incompetence on Physiologic Responses During Progressive Exercise in People with Parkinson’s Disease
European journal of applied physiology(2024)
摘要
Heart rate (HR) response is likely to vary in people with Parkinson’s disease (PD), particularly for those with chronotropic incompetence (CI). This study explores the impact of CI on HR and metabolic responses during cardiopulmonary exercise test (CPET) in people with PD, and its implications for exercise intensity prescription. Twenty-eight participants with mild PD and seventeen healthy controls underwent CPET to identify the presence or absence of CI. HR and metabolic responses were measured at submaximal (first (VT1) and second (VT2) ventilatory thresholds), and at peak exercise. Main outcome measures were HR, oxygen consumption (VO2), and changes in HR responses (HR/WR slope) to an increase in exercise demand. CI was present in 13 (46
