Xert Breakthrough With Physiological Metrics

Xert Is On Board With Some Serious Physiological Observations My Client, Dusty, achieved an Xert Breakthrough while I observed his Physiological Metrics. This is Part 2 of what will now be a 3-part series of videos. In Part 1, I described the physiological phenomena behind a good warmup. Today, we’re going to show how Xert […]

Xert Breakthrough With Physiological Metrics Part One – Warmup

Visualize Your Warmup With SmO2

We Use a Moxy Monitor, a Vo2 Master, PerfPro Studio, and Xert To Show a PROPER Warmup I continue to learn something almost daily when it comes to mixing Physics and Physiology. The data that we get and use for wattage training, is almost always complemented by the information I collect from physiology. We have […]

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.
