Threshold power testing
DP, Portugal 14 Jul 2012

Hi Dr,
I have a question regarding threshold power testing. The most common test is the typical 20' time-trial where at the end you take 5% out of the avg wattage and you get your FTP.
I noticed that if I do an up-hill time-trial in a climb 6-7% grade I tend to get an increase in 20-30W when compared with a flat time-trial where I feel that the momentum tends to lower the wattage constantly, whereas in the climb you get a steady power output.
My question is, what is the best test to determine FTP? the flat or the uphill? and also if there is another alternative test to better determine FTP power?
Thanks in advance!

Normally AT uphill is higher (15-30w) than AT performed on flat course.
The uphill test is easier to perform, if a climb is available.
When possible, the best way to measure AT is direct lactate test at increasing workload.
