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 MPA metrics correlate with physiological phenomena.
The protocol are my favorite Billat 30-30’s. This means a cyclist pedals for 30 seconds of intensity, followed by 30 seconds of recovery. After five to ten intervals above Threshold Power, the cyclist then begins to pedal at intensities above the 3 Minute Mean Max Power.
THE CLIENT
Dusty came into the office with an Xert Fitness Signature of 306 Watts at Threshold, 21.4 KiloJoules of High Intensity Energy (HIE) available, and a Peak Power of 854 Watts. The goal was to attempt an Xert breakthrough, while using a Moxy Monitor and a Vo2 Master, to observe his physiological markers under intensity. I’ll explain what these numbers mean in Part 3.
Dusty is 44 years old, has been back on the bike for about a year, but has no long-term history of fitness or exercise. The bike was borrowed – he did not have a power meter for a road bike at that time. He has been training via Peloton bike and classes, roughly 5 hours per week. His goal is to be a competent coach to his son and friends in their High School Mountain Bike League. He has a power meter for a mountain bike, and a modern Garmin. At the time of the test, he had been using Xert for about 6 weeks. We had some data, but we needed to get a proper assessment.
XERT BREAKTHROUGH WITH BILLAT 30-30’s
Dr. Veronique Billat remains one of my favorite Exercise Scientists. She is the author of vVo2max exercise studies, and I translated those values over to wattage at Vo2max efforts, beginning in 2001. They are the cornerstone of any Alpine Mountain Bike athlete. While Dr. Billat uses 6MMP values, Xert uses 3MMP values to get cyclists to work harder. This is my own interpretation of “Polarized” training. Work done above 3MMP to 5MMP is highly effective for anaerobic intensity and success, just as work performed BELOW Lower Threshold Power, is also highly effective for aerobic economy.
In Part 3, I’ll perform a review and assessment of the activity, and will reveal Dusty’s new Xert Fitness Signature.
Thanks for reading, thanks for watching, and ENJOY THE RIDE!
