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 […]
The Physiological Perspective of Four Separate 8-Minute Intervals
8-Minute Intervals At “Threshold”… In late November of 2024, I was able to perform an interval session on my indoor trainer and bike with my clients. The workout comprised of four separate 8-minute intervals. We used the VQ Velocity app, and I recorded each interval as a separate file while wearing my Vo2Master Gas Exchange […]
Affirming DFAA-1 Aerobic Base With Vo2Master and Moxy
A New Calculation Uses Heart Rate Variability to Better Tune DFAA-1 I’ve been a big fan of Dr. Bruce Rogers, since 2017. He is a trained MD, but publishes his work in credentialed journals. As a Masters’ level road cyclist, he knows how important heart health is. He is also fully aware of the cardiac […]
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 […]
Steve Neal’s Moxy Field
Coach Steve Neal’s Moxy Field Is INCREDIBLY EFFECTIVE! Steve Neal is one of the most successful and qualified coaches that I know. He and I have followed a similar path. We both owned Cycling Studios. He and I have worked together to employ features in PerfPro Studio. He is a pioneer in Diaphragm breathing protocols. […]
More Fun With DFAA-1
“Using an old copy of RaceDay Apollo, a program invented by Dr. Philip Skiba, the software showed a .9799 (97.99%) probability factor that I would be able to hold 230 watts over 30 minutes. This product is no longer on the market, but copies of it are prized. With that number in mind and knowing that I did not have much intensity under my belt, I attempted to match or possibly break this value….”
Billat 30-30’s – Part Two
“Billat 30-30’s are intervals that require a hard effort for 30 seconds, followed by an easy recovery for 30 seconds. Over time, the body ends up playing ‘catch-up’, through heart rate, breath frequency, demand for oxygen at the muscular level, and a buildup of lactate in the system.
We can see this buildup through lactate testing, which is invasive and cumbersome, but we can also see it through SmO2 values, as muscles de-saturate and re-saturate. Lactate is getting processed back into energy, but sometimes the demand for oxygen is greater than the body’s ability to provide it. “
SmO2 (Saturated Muscle Oxygen) From Two Locations During Billat 30-30 Intervals
This is a chart from PerfPro Analyzer 2021 (Beta). PerfPro Analyzer continues to be my favorite workout and programming tool. It has the best display, the most customizable options, and Dr. Skiba’s Metrics are PUBLISHED and PEER REVIEWED. This cannot be said about other “Cycling Fitness” Platforms or their AstroTurf PhD’s. Remember, “In God We Trust, All Others Bring Objective, Peer-Reviewed, Published Data With Valid Hypotheses!”
Specifically, look at the two lines on this graph. The Upper Line is my SmO2 value from a Moxy Monitor placed on my Left Lateral Deltoid. The Lower Line is an SmO2 Moxy Monitor placed on my Right Vastus Lateralis. This image is from my warmup.
