While the role of exercise in the prevention and treatment of various acute and chronic diseases such as obesity and diabetes is well documented, the implementation of a high intensity exercise program for clinical populations is regarded by many practitioners with concern. The efficacy of high intensity interval training (HIIT - >80% maximum aerobic capacity) to elicit improvements in athletic performance has been documented for 100 years and is regarded as integral to both endurance and anaerobic sport performance. In athletes, HIIT has been shown to significantly improve various markers of cardiac, pulmonary, and muscular system and tissue function. However, due to the strenuous nature of this training, the perceived risks of HIIT for at risk or known clinical population’s, has traditionally been regarded as too great. Contrary to this, researchers in recent years have not only demonstrated HIIT can be implemented safely in these individuals but also that HIIT significantly improves functioning in chronic stroke survivors, heart failure patients, and other clinical populations. The purpose of this presentation is to highlight the emerging and successful role of HIIT and outline the specific exercise protocols used, to provide a platform for discussion on the practical use of HIIT in clinical populations.
