exercise good for you - large study

[simonineaston]

Brisk walking, dancing, riding a bike, playing tennis or hiking can all substantially cut the risks of early death, cardiovascular disease, and certain cancers, including those of the head and neck and myeloid leukaemia, Cambridge University experts have found.

I’m not sure why anyone needs a huge collation f scientific studies to make this point, given that The Wombles issued definitive guidance decades ago.

The revalation here is not just the exercise its how little you actually need to produce a beneficial result. Most regular cyclists will be getting far more, I wonder what that does?

It says that the rate of risk reduction is steep up to 8.75 mMET hours/Week, then gradually levels out up to 17.5 mMEThours/week, beyond which any improvement is “small and uncertain”.

I always find the MET a confusing unit, and the mMET doubly so, so am unsure how to turn this all into something meaningful in terms of cycling hours ….. when doing the calculations should I be subtracting “subsistence power” from the average power output during cycling, which yields depressing results, or should I simply use the average power during cycling, which gives quite heartening(!) results?

Makes us virtually immortal, I guess.

Yes. It's a pretty consistent finding. And a very important message both for individuals and public health policy.

I wonder whether public health guidelines on exercise are that helpful, when so many find the concept of exercise daunting, and would benefit simply from a 15 minute walk every day.

Thanks for posting.

That seems to imply that the current guidelines for individuals are different from what has been found in these studies...

Getting back to Al’s point and attacking it another way, it seems that cycling involves working at about 6-12 METS for varying speeds/intensities of ride short of racing, so we might get to the point where any further improvement in our physical health resulting from it is “small and uncertain” after as little as two or three hours of it each week. I reckon that the mental benefits rack-up far beyond that though.

Trouble with cycling is its to efficient one has to do loads.

I'd also assume that too much exercise is bad for you (to some extent at least) - just from a wear and tear point of view.
Probably outweighed for the vast majority of people by the positive benefits though.

It improves the thrusting muscles and sinews to a fantastical degree. Also, it reveals the full danger of the vast and evil motoring addiction.

When taken too far it can do queer things to the brain, as can be seen in this forum!

Cugel, butch as a fitter's cat.

Yes - and we would never have known if there hadn't been this exciting study, eh?

Cugel, recalling how consultants justify their role by borrowing your watch to inform you of the time as they give you a large bill for "the service provision".

DANGER! DANGER! Possibility of spurious data and analysis overloads, distractions and self-defeating confusions when arbitrary metrics are not achieved.

Cugel, too clever (natural/sceptical mode) too be too clever (study/data mode).
