HIGH INTENSITY INTERVAL TRAINING (HIIT) PROMOTES SIMILAR HEALTH BENEFITS AND WEIGHT-LOSS IN A FRACTION OF THE TIME COMPARED TO STEADY-STATE CARDIO.

High intensity interval training may be benefcial to those who want to lose weight and gain cardiovascular health benefts in a shorter amount of time compared to moderate intensity steadystate cardio (SSC). It has been confrmed that SSC can promote metabolic and cardiovascular health and so have been at the fore front of weight, blood glucose (Warbourton, 2006b; Boutcher, 2011; Boule et al, 2001) and blood pressure control (Skutnik et al, 2016). HIIT has made claims to achieve sim- ilar results (Falcone et al, 2015; Jelleyman et al, 2015; Rognmo et al, 2004; Litle et al, 2011) in just half (Hood et al, 2011, Garber et al, 2011) or one-third of the tme (Skutnik et al, 2016). The idea of interval training is not a new concept, the Wingate protocol has been introduced for research purpose in 1974, however, nowadays there are lots of diferent types of high intensity interval trainings used. In recent decades, health practtoners have followed the exercise recommendatons of the American College of Sports Medicine on moderate intensity exercise, which said to be minimum of 150 minutes for the wider public (Whaley, 2006). In 2011, they have extended this onto vig- orous intensity cardiorespiratory exercise. Their recommendaton is three tmes a week of minimum 20 minutes vigorous exercise, such as HIIT, ideally totalling 75 minutes a week. This is a very important step, as the primary reason preventng individuals from exercising is said to be lack of tme (Gillen –Gibala, 2011; Skutnik et al, 2016). This article would like to look at the research-based reasoning behind this recommendaton and the actual implementaton of HIIT.
