FeaturesPractical Recommendations for High-Intensity Interval Training for Adults with Cardiovascular DiseaseWay, Kimberley L. Ph.D., AEP; Terada, Tasuku Ph.D., ACSM-CEP; O’Neill, Carley D. Ph.D.; Vidal-Almela, Sol M.Sc.; Keech, Andrew Ph.D.; Reed, Jennifer L. Ph.D., RKinAuthor Information Kimberley L. Way, Ph.D., AEP, is a lecturer in the School of Exercise and Nutrition Sciences and a clinician researcher at the Institute for Physical Activity and Nutrition (IPAN) at Deakin University, Australia. She is an accredited exercise physiologist with ~10 years of experience, predominately in cardiovascular rehabilitation. Dr. Way’s research program examines the role of exercise and physical activity in the management and prevention of cardiovascular pathologies with a specific focus in adults with cardiometabolic diseases. Tasuku Terada, Ph.D., ACSM-CEP, is an ACSM-certified clinical exercise physiologist and a senior postdoctoral research fellow in the Exercise Physiology and Cardiovascular Health Lab housed in the division of Cardiac Prevention and Rehabilitation at the University of Ottawa Heart Institute, Canada. His research focuses on exploring the role of exercise in counteracting the development or progression of chronic health conditions, including obesity, type 2 diabetes, and cardiovascular disease. Carley D. O’Neill, Ph.D., is a strategic endowed postdoctoral research fellow in the Exercise Physiology and Cardiovascular Health Lab at the University of Ottawa Heart Institute and a certified exercise physiologist with the Canadian Society for Exercise Physiology. Her areas of research include exercise physiology, cardiovascular and respiratory health, and women’s health. Sol Vidal-Almela, M.Sc., originally from Spain, completed an M.Sc. in Clinical Exercise Physiology at Liverpool John Moores University, England, and is now a Ph.D. candidate in Human Kinetics in the Exercise Physiology and Cardiovascular Health Lab at the University of Ottawa Heart Institute, Canada. She has a strong interest in advancing our understanding of sex- and gender-based differences in the response to acute and chronic exercise in clinical populations such as patients with heart disease. Andrew Keech, Ph.D., has been an exercise science practitioner for more 20 years and a lecturer in Exercise Physiology at the University of New South Wales, Australia, for 8 years. Andrew is currently focused on researching the benefits of exercise for cardiovascular health and fitness in healthy and chronic illness populations, with an emphasis on high-intensity interval training. Jennifer L. Reed, Ph.D., RKin, is the director of the Exercise Physiology and Cardiovascular Health Lab at the University of Ottawa Heart Institute, assistant professor in the School of Epidemiology and Public Health, and adjunct professor in the School of Human Kinetics at the University of Ottawa, Canada. Her research program examines the role of exercise in cardiovascular disease prevention and rehabilitation, with a particular focus on women’s heart health and atrial fibrillation.

Active or passive recovery interspersed between high-intensity intervals should be equal to or greater than the duration of the high-intensity intervals. Passive recoveries should be avoided if a person experiences vasovagal symptoms/events. Copyright © 2021 by American College of Sports Medicine.
