High-intensity interval training (HIIT) refers to repeated sessions of intermittent exercise performed above moderate intensity or the heavy intensity domain. It mainly encompasses vigorous intensity or the severe intensity domain, as demarcated by various indices including those related to oxygen uptake, heart rate, perceived exertion, blood lactate, or work rate. The concept of HIIT in the prevention and treatment of cardiometabolic disease has been advanced for decades. This includes application of the method in apparently healthy individuals and in a rehabilitative context in patients with cardiovascular disease. Like other forms of regular aerobic physical activity, a key response underlying the potential for HIIT to enhance health is likely an enhanced capacity to transport and utilize oxygen, as reflected by increased cardiorespiratory fitness. Given the strong, inverse relationship between cardiorespiratory fitness and morbidity and mortality, research is warranted to clarify the efficacy of various HIIT protocols and how these compare to traditional, moderate-intensity continuous training using robust study designs. This session will consider the physiological basis of responses to HIIT and application of the method to prevent and treat cardiometabolic disease with a focus on cardiac rehabilitation. The content will have relevance to those interested in basic, applied, and clinical aspects of exercise prescription in both healthy and diseased states.

This presentation will consider evidence regarding the physiological basis of responses to high-intensity interval training to enhance health, with a focus on cardiorespiratory fitness and glycemic control. Emphasis will be placed on the role of brief, vigorous intermittent physical activity including emerging evidence regarding the efficacy of “exercise snacks” in both healthy individuals and those living with cardiometabolic disease.

This presentation will discuss the clinical role of high-intensity interval training versus moderate continuous training in different cardiovascular patient populations addressing coronary heart disease, heart failure and atrial fibrillation, particularly addressing clinical outcomes including morbidity and mortality.
