Vo2Max and Heart Health – A Single Ride Following Dr. Paddy Barrett’s Formula

Vo2Max and Heart Health Correlation With DFAA-1 and other Metrics I recently stumbled across a Substack post by Dr. Paddy Barrett that explains how Vo2Max is impacted by low intensity exercise. While I had not known about Dr. Barrett previously, when I read his history and other posts, I became intrigued. I think he’s a […]
Vo2Max and Mountain Biking

Mountain Biking Requires Riding at Vo2Max! CAUTION – THIS POST IS NERD-HEAVY! IT IS DEEP IN THE WEEDS! DO NOT HESITATE TO ASK QUESTIONS!!!!! Ever since I received my Vo2Master back from my friend and code buddy in Canada, I have been collecting data on inside and outside rides. Not long ago, I rode two […]
Vo2Master Vo2Max Value Affirms Garmin Vo2Max Estimator

Vo2Master’s Vo2Max Value Was 98% Consistent with Garmin In May of this year, I wrote a post about the Garmin Vo2Max Calculator. In July, I was able to test my Vo2Max at OBC Headquarters, to compare values. I performed a Graded Exercise Test, using the Vo2Master app. This app, on a cell phone, trapped data […]
Vo2Max On Garmin Connect and the Garmin 1040

Vo2Max Calculations Show Cardio-Vascular Changes Vo2max is a fitness and health measurement that is defined as, “The Maximal Volume of Oxygen that can be consumed by a person during physical exertion.” I’ve discussed Vo2max in the past, and I even own a Vo2Master assessment device, for testing and training purposes. Garmin Connect uses information collected […]
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.

Xert 5MMP
Xert 5MMP – Can I REALLY Achieve A Breakthrough? I’m just nine days out from my Peak date per Xert. My Xert 5MMP is reading “355”, and it floats between 355 and 357. I rode some 5 minute intervals yesterday and barely broke 302! The Vo2 data is showing that 355 will be a true […]
