The relationship between intense interval training and its fitness benefits has generated much discussion for some time now. Indeed, it has been the subject of various studies over the years and for many who make interval training their big thing in the gym the allure of a few minutes of intense interval exercise having the same impact of more time consuming endurance training is very powerful.
If intense short bursts of training gets results, think of the time you can save if you make it your core routine!
Also known as HITT (which is, of course, sexy in itself) high intensity interval training has become particularly attractive to those new to training who are looking for fast results. It also has its advocates in the fitness programme and supplements market and, if you think about it, HITT sort of makes sense: After all, if you train hard, rest, train hard, rest etc. surely your body will benefit from pushing its fitness boundaries?
Putting aside the discussion about how beneficial HITT can be for those who build it into their training programme (and there is a lot of evidence that it does provide benefits) recently researchers from Stockholm’s Karolinska Institutet discovered that the cellular mechanisms behind the positive benefits of HIIT can be undermined by the effects of antioxidants on the body.
You can find out more about the results of this study (though be warned, as some of it is a little on the technical side!) in Dean Smith’s report on its findings.
