High intensity interval training is undoubtedly one of the most talked about weight loss tips of the 21st century. But if you are unsure why so many gym lovers are jumping on board the HIIT train, you're about to find out the main reasons.
Today you will discover the science behind HIIT and the reason it has become such a practised method in gyms around the world over the last few years.
Despite being over twenty five years old, HIIT is still fairly unheard of in much of the fitness world, with many regular gym users still succumbing to the old strategy of performing long, steady state cardiovascular exercise to hit the often fabled fat burning zone. Thanks to the constantly developing scientific studies behind the health and fitness industry, long steady state cardio is now yesterday's advice for those who are looking to burn unwanted body fat!
To go back to the roots of HIIT, you need to look at the two studies which brought it into the public eye. The first of which dates all the way back to 1985. Initially designed to test if exercises helped speed the metabolism, scientists noticed that most of the weight loss results were from individuals working harder in the gym. A further study confirmed this, with three weekly HIIT sessions outperforming five regular cardio workouts for fat loss, despite those workouts being twice as long.
From there, interest in this subject was high and research was being carried out almost every single year. Many athletes adopted it to their own training regime. Sprinters and swimmers were particular fans at this point.
A Canadian study in 2001 then produced the most thorough research on the subject to date. It detailed that a group of exercises not only lost more body fat while working out for less time and less often, they also increased the body's fat burning enzyme HADH. This finding was initially quite shocking, because HIIT is known to use carbohydrates as the source of fuel in the gym, not fat. This increase in HADH occurred because high intensity activity actually causes the body to switch to using fat for fuel in the period following a workout. Furthermore, this period can last a shocking 14 hours in length. []
By increasing the production of HADH after each workout had finished, the body is able to switch to using fat for fuel over the course of the next 12-14 hours.
The study went on to show that it also increased lean muscle mass and prevented muscle breakdown during exercise. The best result of the study, however, was the fact that the HIIT group burnt off over six times more body fat than their steady state cardiovascular counterparts. This showed that one calorie burnt during a HIIT workout was equal to six during regular cardiovascular activity.
Since then, of course, countless new studies have went on to confirm the effectiveness behind interval training and it has become one of the most talked about discoveries in the history of the fitness industry, with countless personal trainers and fitness experts putting their weight behind it.
Like all new fitness concepts, high intensity interval training has recently made it's appearance in the mainstream. This can lead to some labeling it as a passing fad but, having seen the mounting evidence behind it's effectiveness, you now realize that HIIT can become one of the most productive weight loss tips for those who are prepared to learn a little bit about it before jumping in.
