Xert FTP Tested
Xert Claims my FTP (Functional Threshold Power) Sits At 265 Watts. Is It Accurate?
I’ve always wondered if calculated Functional Threshold Power Values are accurate. Since 2017, however, I have relied on the Xert FTP value.
For years, we relied on the “20-Minute” Test. Riders would perform a 20-Minute effort, all out, and then subtract 5% from that value. The new number was considered “Threshold”.
Later, physiologists looked at 90% of a 3-Minute Maximal Effort.
There’s the 5-1-5 test….
Step Tests (25w steps every 3 minutes)…
Ramp tests (15-20w every minute)…
The latest ‘Testing’ asks for a 20-minute, 5-minute, 1-minute, and 5-second effort.
