Regular exercise can assist in reducing body fat and protect against chronic diseases associated with obesity. High intensity interval training (HIIT) has become a popular time efficient approach to improve cardiorespiratory fitness and decrease the risk of cardio-metabolic disease. HIIT involves alternating short bursts of high intensity exercise with recovery periods or light exercise. Studies in obese individuals have shown that increasing the intensity of exercise amplifies the training stimulus and associated adaptations, such as VO2max, anaerobic threshold, stroke volume and exercise performance. This presentation will discuss the evidence for the use of exercise training, including HIIT, in the management of obesity related chronic disease. Practical approaches to incorporate exercise training such as HIIT with obese patients will also be provided.
