Recommendations to the public on the quantity and quality of physical activity to improve health have long included vigorous physical activity. In fact, vigorous activity was the focus of most guidelines prior to the Centers for Disease Control and Prevention/American College of Sports Medicine recommendation published in 19951. While much has changed in the ensuing 25 years — and even as public health recommendations have evolved to place a much greater emphasis on moderate physical activity2 — the general public and professionals remain intrigued by vigorous physical activity. This may in part be due to many researchers and clinicians having personal and professional backgrounds in sport and endurance exercise. In this commentary, we will look carefully at whether it is still justifiable for public health and clinical practitioners to retain a significant focus on vigorous physical activity. First, we will define “vigorous physical activity” and then attempt to address five questions about this issue: 1) Are there health benefits of vigorous intensity physical activity in addition to those of an equal volume of moderate intensity physical activity? 2) What are the risks associated with vigorous physical activity? 3) How much vigorous physical activity actually occurs at the population level? 4) Are there intervention strategies to increase and sustain vigorous physical activity in populations? 5) What are the health benefits of HIIT (High Intensity Interval Training)?
