Hot Air …

Over the last few days I’ve estimated my VO2max by some of the many methods available to those unfortunate enough to lack a gas analyzer and cycle ergometer.

The first couple of methods don’t involve getting up out of your chair, the second is the simplest – the inputs are just your resting pulse and your age. The next two involve exercise. The inputs are your weight and active pulse or measured power.

The Rockport test doesn’t involve exercising at maximum capacity, at least not unless you are totally out of shape, therefore it is suitable for elderly gentlemen. The six minute power is meant to be a maximal effort.

It is interesting how close the results cluster together. Whether that is anywhere near a lab measured VO2max is an unknown.

VO2max peaks in young adults and then declines at about 1% a year. Young and middle aged men can halve the rate of decline by regular vigorous exercise but the rest of us are stuck with it. It is largely the consequence of a declining maximum heart rate. The second most important culprit is increasing body fat.

After 70 it’s supposed that VO2max drops off a cliff but the evidence is getting pretty thin at that stage. Clearly nobody told Giuseppe Marinoni who set the Hour Record in the men’s 80 to 84 category last year by cycling 39.004 km.

Great things are still possible.
