High Intensity interval training (HIIT) or Sprint interval training (SIT) is a training method that has garnered a lot of attention within sports science. It has become a recent favourite among fitness professionals (Driver 2012). A lot of articles write about how it should be implemented, but very few seem to explain the science behind HIIT. The aim of this article is to do just that!

What is High Intensity Interval Training?

Everybody from professional athletes to the average gym goer wants to make physiological changes and adaptations to their bodies in as short a time as possible. The addition of SIT to a training program allows physiological adaptations and improvements in performance to be made using a lower training volume (Kubukeli, Noakes, & Dennis 2002).

SIT and HIT, consists of numerous repeated maximal effort sprints. The volume of this training is usually four to six sprints per session, with four minutes of recovery in between (Hazell, Olver, Hamilton & Lemon 2012).
