Folks,

I was wondering if anyone could offer me some help with our road cycling
testing protocol.

We take a blood lactate profile of cyclists on a kingcycle ergometer. It is
an air braked unit which the cyclist places their own bike on. The unit
calibrates for the cyclists back wheel drag. The unit has been found to
correlate to a calibration rig within 1% tolerance but I suspect there is
variation in reality.

The protocol we use is for male cyclists:

start at about 150 watts and increase by 30 watts every 3 minutes whereby
taking a blood lactate sample. The tests goes on until the athlete decides
to stop.

We used to stop once a reasonable indication of threshold was obtained but
we continue now to look at lactate tolerance.
We used to also sample VO2 towards the end of the test but these days we
only do it once per year.

I would be interested if anyone could point out any flaws in our approach,
perhaps if people could contrast with their own protocol, if there is an
accepted protocol that I am ignorant to or just any advice they could give
us about how they set their testing up.

In addition to this we take skinfolds, height and weight.

I am interested how some people might set workload according to mass,
perhaps if anyone is using economy and how they are administering the
protocol.

If a power to weight figure is used how is this done, maximum power at the
end of a lactate profile? A maximum power over a 10-30 sec sprint or perhaps
even power at aerobic threshold (crossover point of aerobic to anaerobic
metabolism)?

Thank you in advance for any help you can give me. I will collate any
responses and distribute once permission is granted.

cheers
