Interval Training for Health and Fitness: HIIT Versus Hype?

Interval exercise involves alternating periods of exercise and recovery. Athletes have employed the practice for over a century, but the last two decades have seen a resurgence of scientific interest into the physiological and health-related adaptations to this type of training. The method is infinitely variable but can be broadly classified into two main categories: high-intensity interval training (HIIT) typically refers to submaximal efforts that elicit at least ~80% of peak heart rate, whereas sprint interval training (SIT) involves ‘all out’ efforts or an intensity corresponding to ≥100% of the workload that elicits maximal oxygen uptake (VO2max). Studies comparing HIIT and moderate-intensity continuous training MICT, matched for total work or energy expenditure, have generally found intermittent exercise elicits superior adaptations in both healthy and diseased states, including cardiorespiratory fitness and indices such as glycemic control. Other recent work has shed new light on the potential for SIT, which involves a small total volume of exercise, to elicit adaptations that are comparable to MICT despite a smaller total exercise volume and time commitment. These findings are noteworthy given that lack of time is one of the most cited barriers to regular physical activity. This session will review the physiological basis of interval exercise and examine the role of intensity, duration and volume in regulating training-induced adaptations. It will also consider the practical application of interval training in both healthy individuals and people with cardiometabolic diseases.
