# Watt max bicycle fitness test

For anyone who wish to measure fitness accurately, this test is one of the best. The test requires a reliable bicycle ergometer and it requires maximal bicycling effort from the person being tested. With these requirements fulfilled the test result will be very close to what can be measured with laboratory equipment.

The Watt-max test is a maximal test conducted on a bicycle ergometer. It is one of the best indirect tests of VO2max available.

Instructions:
1. Start on a workload of 35 watt and increase with 35 watt every 2nd minute.
2. Continue untill the workload can no longe be maintained.
3. Note the highest workload reached and how many seconds you managed on this workload.

This calculator is also included in Fitness Test pro

Background:

The energy cost for doing bicycling at any given workload is fairly consistent among different individuals. Therefore maximal oxygen consumption can be estiamted by measuring the highest workolad that can be performed under reasonable aerobic conditions.

is there any difference the down hill and uphill on this? thanks

is there any tutorial on how to use on this?

Laco,
I would guess that in tests that involve power, cadence is not really a factor. 100W in a high gear takes the exact same effort is 100W in a low gear. I usually just maintain 90-100RPM, as per the norm.

Because workload is changed every second minute, time is used to calculate the specific maximum performance. Hte difference between stopping after 2 seconds on a workload or after 118 seconds. Time is also included in the original reference.

In teh original reference, time is not included in the equation. What about the Health calculator, how does it use time as a parameter?

In the original reference a cadence of 70 RPM was used, so you should aim for this, but it actually depends on the bicycle ergometer you use. If the ergometer is capable of keeping a fixed workload (in watts) independently on cadence, then cadence is not important. Especially for very fit persons, it is advicable to allow for a higher cadence when workload passes 350 watts.

pls indicate the minimum cadence accepted by the test.
