The truth about exercise

I think you're about to be corrected on the first one...

Most of this seems to be simple common sense that our grandparents knew without the benefits of modern science: keep active, eat and drink in moderation, eat your greens, go for a walk after a big meal to "settle" the stomach....

I really enjoyed the programme.

Good news for haters of turbo training, sprint like Cav for three 20second spells job done, mines an espresso thanks.

Peddle Up!

Mosley is an excellent presenter, but I think the programme was a bit of a letdown with so many unanswered questions. I can only assume that the message was aimed at folks who do nowt, or those who sit on an exercise bike in the gym iPodded up and pedalling at a cadence of ten and wonder why they can't lose weight/feel fitter.

For what it's worth I sometimes feel that my body behaves like my laptop and goes into "power saving states" only delivering energy when demanded (and I mean demanded, not "asked for"). I guess that fits with the HITT regime "waking things up".

Just watched this via I Player. A very good friend is in this. (In the gym sweating his knackers off in the gym LOL)

Enjoyed the program

I don't know the truth about all of this, but it is pretty close to the genetics of people's ACE (angiotensin converting enzyme) where 25% of the population will never improve their endurance with exercise, 25% will keep improving day on day and the other 50% are somewhere inbetween. The first group put muscle bulk on when they use weights and the (fit) group can't increase muscle bulk however hard they try.

The whole point of that research, which came out about 10 years ago, was that when the different groups were admitted to ITU with sepsis, the unfit group had nearly 10 times the death rate than the fit group, but were more likely to get kidney failure.

There is a link to the paper they mention on the programme http://jap.physiology.org/content/108/6/1487.full#abstract-1
which explains roughly what they did, though doesn't seem to mention which genes they use other than Creatinine Kinase Oxidase which is found in muscles.

I really enjoyed the programme as well, but most of those at work who saw it were really impressed that your glucose tolerance and insulin sensitivity can improve that much. They didn't mention if everybody improved in the same way or was it just those with bad genes.

I suppose this does show that you have to tailor healthcare to the individual, not just the one size fits all approach we are bound by at the moment in the NHS.

Some years ago I read "Training, Lactate, Pulse rate" and this study indicated that long walks are the best way to lose weight (combined with regulated calorie input) as the pulse rate is below the aerobic threshold and the body is converting fat for energy to be used by the muscles, where as in the aerobic zone carbohydrate is burnt and no fat.

Fat is always used,it's the percentage of it that changes

So are we saying that in the aerobic zone more carbohydrate than fat is used particularly the closer you get to the anaerobic zone.

I thought that the programme was there to show how doing the VO2max type of exercise gave health benefits. That's all. TBH it is better that lazy people get a quick fix for health reasons. Provided they can be motivated. It shows they don't have to get really fit if they don't want too.
It is that VO2max is the significant part of the exercise and it is possible to ride around without getting to that level. I know I do because I use a HRM . It would have been more fun to watch if they got somebody who was less fit(fat) to do the exercise. I know my OH would be totally gobsmacked at the suggestion.
However, doing flat out 20 second sprints x 3 x 3 per week for a TT or tourist rider could be helpful. Also, its not that easy to do. The other thing is, did the rider have any resistance on the static bike. Was he spinning and doing an anaerobic looking exercise. Because it is possible to exercise like that and not get in to the VO2 HR zone. Did they quote his HR, I can't remember?
