The Truth About Exercise With Michael Mosley is playing on PBS in my area (central TX) tonight at 9pm, hour long show. I'm not sure how they schedule between various regions but if you're interested you may want to check your local listings.
 
Thanks for this - it's showing in Chicago at 10:00 PM - I will be watching. Again, thanks for sharing this info. :)
 
I loved his series! This exercise one really helps me. When I go to the beach I make sure I get my minutes in. LOL

I was only able to see bits & pieces of this show. The part I saw was explaining the importance of walking and moving throughout the day. I am such a HUGE advocate of simple steps! Anything I can do to get my steps in throughout the day, I will do! To me, steps are as important (if not more) as weight training or cardio. When I can't exercise to a workout video, I will always make sure to walk at least 2-3 miles (indoor/outdoor). It DOES make a difference :).

I watched this last night from DVR, and while it was interesting to see the science, it is billed as the "truth" I found that a little misleading because it was more like half-truth.

I do not doubt the test of insulin response, but I'll have to look at look at that non responder to exercise part again, I'm not sure I agree with what they stay about non-responders to exercise, there could be other reasons for that, personal history, perhaps.

The half-truth part is you can not just ignore the effect of HIIT on other systems of the body, I believe, on the nervous system it activates & the impact it has on the circulatory system. Plain & simple, it's stress. (the highest kind of stress) It's not popular at the moment in science or industry to illustrate what is happening to you if you focus solely on HIIT for fitness & health.

What I do agree with is that he did mention being active all day, or more so all day long, although there seemed to be just a passing note on that. I think that is much more important than the interval training "science".

For top athletes & everyday people, I still believe, low intensity AEROBIC exercise, regularly & daily if possible, and an active lifestyle is the way to keep your entire body system healthy & happy. It's low stress, and balanced with healthy eating the benefits are exponential. For athletes low intensity aerobic exercise is your base, using the pyramid analogy, the base is all the stone used to build it right up to very near the top, HIIT is the capstone, that is all it is. You don't even need the capstone to do very, very well. And not at all if you're not competing. But if you're going for that world championship or gold medal, and if your sport is anaerobic, in nature, you might.

I think if you really want to see an improvement in health & fitness you would have do a long term study, like 5 years or 10, you would want to compare aerobic exercise & HIIT side by side. The other part would be to add diet into that, because I believe that certain foods also increase circulatory system & bone health. So four part, aerobic vs. anaerobic exercise, plant based diet vs. "average" diet. And the various combinations. You would think with all this technology, we could do studies like that.

There is no short test, no quick solution, to how to live a long happy healthy life. IMO. I just think the more time you put into it, the more you get out of it, and the easier it is.

Whoever said nothing easy ever mattered, was wrong. It is easy.

I think this series from Horizon (BBC) is excellent in illustrating using one guy (Mosley) the state of research into different exercise modalities. However, they haven't been very clear in the editing or the way the scientists talked about the results. It sounded like Mosley is a non-responder to aerobic exercise when what they actually said is that he is a non-responder to the 3 minute all-out protocol. It doesn't say anything about his aerobic capacity.

The important message is what happened when he took the single 90 minute brisk walk and then ate that "breakfast". His body responded by altering fat metabolism. This is the kind of response that drastically lowers heart disease by controlling circulating fat on a daily basis. In another part of this series, they looked at calories burned from doing the same 90 minute brisk walk (6 miles). He burned about 170 calories from fat during his walk which is pathetic. However, over the next 18 hours he continued to burn more fat (500 calories more) and he still had few more hours to go. This experiment shows why lower intensity easy cardio works so well for weight loss for the majority of people.

The 3 minute all out a week is trivial from a fitness standpoint. It doesn't really improve VO2 max that much. From controlling healthcare cost, it makes some sense. If 10 to 20% of the population who are responders to this type of exercise do the 3 minute a week on a regular basis, it can delay the onset of diabetes and other diseases and save healthcare dollars. Plus, people might be convinced to do 1 minute 3x a week. It is much harder to convince them to do a brisk 6 mile walk everyday because of time constraints.

What I would like to see is what happens to his VO2 max when he is put through a proper aerobic base building regimen for 6 months. I'm willing to bet he will double his aerobic capacity and be able to maintain it on less than 90 minutes a day.
