Where is the evidence coming from that Hi Intensity Interval Training [HiiT] is appropriate, suitable, healthy training that will yield the results that we seek? The evidence is coming exclusively from short term studies (i.e. 3 week to 12 weeks at the longest). I have yet to read any study that demonstrated with any degree of reliability or validity that HiiT works over the long term.
But aren’t results over 3 weeks or 12 weeks sufficient?
Seriously? Did you not read the excerpt from the article above?
If you watched “The Biggest Loser” series, you will remember that every week at the end of each episode all the participants would ‘weigh in’… they would line up behind their trainer – Bob Harper and Jillian Michaels in the early days of the series – and one by one they would be called down by the host to stand in front of everyone on a massive scale where their weight was shown on an equally massive screen hanging behind them.
Results? Absolutely, there were results… in fact incredible results! Participants in the series would lose 8, 10, sometimes 14 lbs… and that was in a single week. Some participants would lose this sort of weight, week after week. And in the series finale, they would burst through an image of their former self, in a grand reveal of their ‘new’ self… trim, shapely, firm, fit, with hair, nails, and outfit to match their new identity.
Results? Absolutely… review any triathlon, running, cycling or endurance event website and there will be article after article expounding on the benefits of HiiT! From weight loss, to maximizing cycling power, to decreasing risks of cancer… you name it… HiiT is the snake oil con-men and con-women are selling at every opportunity.
Risks? Side-effects? Consequences? Are you kidding…
Who cares about those when you can have “Biggest Loser” weight loss results in days or weeks instead of months & years of training?
Who cares about those when you can set a new FTP/critical power level, or a faster split time in days or weeks instead of months & years of training?
And then an article publishing the results of a long term study of those who participated in “The Biggest Loser” reality series: all the short term gains are lost in time, and in addition the participants are left in far worse condition then before as a result of their physiology being decimated by the hi intensity training/HiiT that Harper and Michaels subjected them. Please also recall if you watched the series, that the reality series was performed while all participants were under the (again, so-called) ‘expert’ guidance and medical supervision of medical doctors.
Take short term scientific research that concludes HiiT yields incredible results, fail to perform any research to see if those results are sustainable, or to evaluate if those results truly lead to lifestyle changes that yield long term results which are healthy, and voila… a con job of epic proportions that convinces the masses that health, fitness, weight loss, et al. is just a handful of painful, puking hi intensity sessions away!
Furthermore, the bias that now exists to protect HiiT as the be-all and end-all form of healthy training is unreal. With teenage age group athletes, and young adult men and women who are pro athletes now consistently being either diagnosed with arrhythmias or ending up dead while training or racing, plus masters athletes dying in marathons, triathlons, and other endurance events its amazing how an alternate explanation is always found… and never ever is the appropriateness nor the safety of HiiT questioned.
The selective blindness is itself a key marker to how effective the marketing of hi intensity training has been. No one wants to accept that so-called experts failed to do the long term research to determine whether or not HiiT was as good as short term studies suggest. No one wants to accept that they have been conned. No one wants to accept that what they have believed, how they have trained, how they have raced, how they have approached health… is wrong.
Not even Jillian Michaels wants to accept that her entire stardom and celebrity status is built upon bull: when replying to questions regarding her former co-star’s heart attack, Michaels found the excuse to be in Bob Harper’s genetics and diet. That Harper has changed his training from hi to moderate intensity… well, that’s conveniently wiped from short term memory.
