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.
Although it has only recently crossed over in to mainstream society, HIIT has been used for nearly three decades. It was previously widely believed that cardiovascular activity performed over a long distance at a steady pace was better for both endurance and fat loss. However, recent studies have blown these old theories out of the water.
The first instance of HIIT was discovered by researchers in 1985, who discovered that a group of exercises lost significantly more body fat when they were pushed at higher levels. These findings started a trend of research which attempted to discover the reason behind the results. Five years later, it was discovered that a group of exercisers lost significantly more body fat again while exercising at a higher intensity, despite the fact that the workouts were almost half the duration and took place three times per week, as opposed to a group doing regular cardiovascular activity five times per week.
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. []
That's right, your body burns calories at an accelerated rate for fourteen hours after finishing a HIIT session, most of which will be fat!
Further research in the same study then went on to confirm that HIIT prevented the breakdown of lean muscle tissue in a way that was far superior to regular cardiovascular activity, while also burning off six times the amount of fat per calorie as it's steady state cousin. That's correct - one calorie burned off during a high intensity workout is worth six times the fat compared to one burned off during a low to moderate session.
These startling results have since been backed up by many further studies. In fact, over the last few years this training method has crept it's way into many mainstream gyms around the world and it now appears to have earned it's place among proven fitness techniques.
It now stands tall as one of the most effective weight loss tips for anybody looking to burn maximum body fat in minimum time. If you are considering including high intensity interval training in your workout routine, you now know why countless others in the fitness world believe it to be the most effective way to get results.
