it is a fairly good indicator for use on the general population say for example if you are screening a patient to see if they need an operation today or next week, without doing a serious exercise test screening. but definitely not for athletes. the highest activity level covered on the original scale is equivalent to something like 10 miles running a week, not per day!!
the accuracy also depends on the development populations they used to construct the scale. they do this test then do direct vo2max measurements on the same development population and draw the chart which they base the conversion on so it depends how varied the group were and other mathmatical concepts that i don't really understand.
there are loads of other crude/indirect tests you can do yourself. eg the 12 minute run. how far did you get round a track in 12minutes? someone has constructed a standard equation for converting bleep test results too. #
fitness for orienteering isn't just dependent on vo2 max tho, lactate threshold and running economy come into play too.
btw i'm not a sports scientist/exercise physiologist, this is all based on a couple of modules i did in my undergrad physiology course.

So, alright for me then.Melons wrote:it is a fairly good indicator for use on the general population ..... but definitely not for athletes.
Somewhere at home I've an article about Elite O'ers running through terrain with gas analysers and the VO2 figures were staggering. Don't know where the article's from, but it does mention Steve Palmer using the analysis to improve his training. (it's several years old). I'll dig it out and scan it using OCR so I could post it here if people are interested.

I believe that Foxdal's data showed up the point that VO2 max was not the deciding factor in orienteering. As Melons says running economy etc all play there part. Some of the athletes tested by Foxdal had very low VO2 max compared with thier fellow athletes yet they had much better running ecomomy and could therefore in theory run as well...... (and better in practise) orienteering fitness is determined by so many things and to place the emphasis on one aspect more than another is not such a good idea

i was thinking about the very same thing yesterday when the subject came up, managed to find this about how they came about using it. Seems like it is only useful for those in the middle of the range and not those at the elite end of the range, as shown by some study into it (abstract here).
If I do the VO2 test that Eddie did i can see how close it is i guess...

i expect the development populations POLAR used included a decent range of decent athletes as well as normal people so that is why it works wheras some scales i have seen don't work so well for athletes
if my insurance claim comes back positively i might buy a polar, can you recommend the best one mharky? anyone know if the Sunnto heart rate montiors are any better for orienteers? Marten, Oli and Jenny have them.

well seeing as you have the right phone for it you might as well get the 625x (unless you do lots of cycling and have money to burn then get the 725x)

I've a 610i, and it seems to do all the things that I might ever wish to use it for, but sometimes wish I'd bought the bike one (like every time I go cycling )
I bought mine from http://www.sportsaver.co.uk as they were (and still are) cheaper than Brooner's shop. I think some friends found it cheaper the other week via web search.

Andy bought the Polar bike one but it never really worked that well. If you put it on your bike when mountain biking the buttons got mud in them and broke. He has switched to the 610i now as have I and they are really good.

That article I was referring to was actually Peter Foxdal's notes from the 1999 BOF Coaching Conference - which I noticed this morning while re-reading it, was attended by your good self.

I've got the 720i - bike computer one - which works great on the road bike although the distance from the sensor to the watch is sometimes a problem - e.g. doesn't work on my tri-bars. If you can live with it being a bit on the chunky side (not a mention a little on the pricey side....) I'd thoroughly recommend.

Yep I think I was there......... and with Mr F on many occassions... remember one of the biggest problems was getting airlines to accept a pressurised gas cylinder........ and that was pre- 9/11. Quite entertaining finding a suitable terrain course on a building site in Tenerife as well:)

For discussion on the whys and wherefores of VO2 not being the limiting factor in elite endurance performance - and a pretty hefty description of running training in general try Tim Noakes "The Lore of Running". It is a bit of a bible, heavy going in places - e.g., a lot of detail on how muscles work, but with a mass of good information.

So what
So once you've measured your VO2 max, and had your mines-bigger-than-yours moment, how does that help your training?

you need to see which area you are weaker in, Vo2max, lactate threshold or running economy/running economy in terrain. they are all related to your aerobic capacity but you can focus your training to improve whichever
vo2max - intervals, specifically ones with short recovery periods
lactate threshold (the %of your vo2max you can run at without accumulating lactate) - running at threshold for increasingly long periods, doing longer intervals above threshold
running economy - lots of running! lots of running in terrain, core stability and leg strength training.
also it's good if you can work out how it feels (RPE relative perceived exertion) when you are running around your vo2max, around your lactate threshold and at different %s of each. just making training more scientific intsead of just going for a run or whatever. i do it just by feelings but some people like to use heart rate monitors and see what % of their HRmax they are at.
i could write lots here but a)i'm not an exercise physiologist so there are lots of people who could put it better i expect (they'd probably charge you tho!) and B) i have to go finish my western blot
