Assessing the Feasibility of High-intensity Interval Exercise in Patients with Peripheral Artery Disease
Year: 2019
Type: dissertation
Abstract: Peripheral artery disease (PAD) is associated with diminished functional capacity. Exercise is an effective therapy, but adherence to traditional exercise is not ideal. High-intensity interval exercise (HIIE) results in greater improvements to aerobic capacity compared to moderate-intensity continuous exercise. The objective of the study is to assess the feasibility of HIIE for patients with PAD, and explore its physiological, subjective and psychological responses. Participants performed: 1) traditional exercise (moderate-intensity walking); and 2) HIIE. Oxygen consumption, heart rate, muscle oxygen saturation and pain were assessed. Participants completed questionnaires to assess psychological responses. HIIE was feasible and safe for patients with PAD. Lower levels of pain were experienced during HIIE and all participants preferred the HIIE. HIIE may be an alternative to traditional walking and should be considered. The potential physiological and psychological advantages warrant further exploration. Reducing pain during exercise may be important to maximizing the chances for patients to succeed.
