Setting The Q Ring Position Based On Rotor InPower Ride Data
Rotor InPower Cranks Provide Crucial Insight I’ve been using Rotor products since at least 2000, when the RSX Cranks first became available. I have been a student of the original concept, and I use Q rings on all of my bikes these days. In 2012 or thereabouts, Rotor began building their own power meters. Specifically, […]
DFAA-1 On a BIG SCREEN!

DFAA-1 with ECG is Now Available On a BIG SCREEN! I’ve been working with two professionals now for several months on a project, and we are ready to start releasing it in ALPHA. DFAA-1 (Detrended Fluctuation Analysis – Short Term Variable #1) is a way to look at Heart Rate Variability and Cardio-Vascular Health. Dr. […]
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….”
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.
Using Ergometer LOAD vs. % SLOPE for DFAA-1 Base Training
“PerfPro Studio is such a fantastic product for training and analysis. It allows a cyclist to ride at a load based on an ergometer, or a load based on % slope. Yesterday, after assessing my DFAA-1 heart rate, SmO2 and wattage values, I decided to ‘test’ the values….”
Physiological Baselines for “Base”.
On Christmas Day, I performed a 60-minute workout on PerfPro Studio. I also recorded the data on Vo2master software. The goal was two-fold. I wanted to perform a ramp test, to try and determine Physiological baselines, specifically Heart Rate at DFAA-1 0.75 and 0.500. I also wanted to see if I could determine Ventilatory Threshold 1 and Ventilatory Threshold 2. Finally, I wanted to determine whether I could ‘See’ deflection points via SmO2.
With this information, I can work on adaptation to higher loads of power and traditional heart rate.
Base Ride Analysis Using Published Science
“In the first part of the video, you can see FatMaxxer being screencast from an Android to the PC window. The second screen is the Vo2master software, which is being screencast to the PC using LonelyScreen app. The rest of the information is being presented through PerfPro Studio. Post-ride analysis was done using PerfPro Studio, PerfPro Analyzer Beta, and Runalyze.”
The Road to 300 Watts FTP
Right Now, It’s NOT about 300 Watts; It’s About Raising LOWER THRESHOLD
The goal of base is to train the body for Economy. Stamina is the fundamental Pillar for Polarized Training. When you train using DFAA-1, you can get a clearer picture of how your body is responding to the training. Wattage and traditional heart rate become
Getting FatMaxxer On the Same Screen As PerfPro Studio
The FatMaxxer App for Android is one of my favorite instruments when used in conjunction with a Polar H10 Chest Strap.
More DFAA1 Files From Myself and my Clients
My Own Sleep Was Not Great, But Things On the Cardio Side Are Really Looking Good Well, once again, I didn’t sleep great last night. I woke up around 1:00am, and was up for about an hour. There is stress at the house with a relative, and that may have contributed. Last night, however, I […]
