A Successful Use of W' in REAL-TIME, During a 20 Minute Test at Cycling Center Dallas

This is just a quick video recap of an exciting result we got last night at Cycling Center Dallas. Using a Client's Critical Power Data, we calculated her W', or, Anaerobic Work Capacity, using PerfPro Studio. Then we underwent an 8 week block of MAP/Vo2Max training. We are testing this week, and did some 'Pre-Test' work last week. Using this Cyclist's most recent 3,8, and 20 minute Mean Max Values, we predicted a Critical Power of ~175w and ~18,100 Joules of AWC. For the Test, I had the client focus on keeping W' as 'Full' as possible for the first half of the workout, and to work on increasing the RATE of use, until, at or near the very end, she was either completely spent, or even below her AWC. On PerfPro, this is depicted on the dashboard as "100% down to -X%", and when you dip too far below Zero, it's usually a good weathervane telling you that you've adapted and have a higher Critical Power, a Higher AWC, or both. This client followed my instructions perfectly, and per her 'OLD' Critical Power, set a new 20MMP of 200w, and hit a "-22%" on her W' during the test. When I entered her new 20MMP, and kept the older 3 and 8 minute mean max numbers, her Critical Power jumped up by 10 watts, but her AWC/W' dropped by about 3200 Joules, or 3.2 KiloJoules. However, MORE IMPORTANTLY, when I applied the NEW CRITICAL POWER and AWC/W' values... the AWC values ended up PERFECTLY ALIGNING, and she ended the test at.... 0% W'. She literally "Left With Nothing Left!", which, as you know, really is my motto. I'm more convinced than ever that this model for Anaerobic Work Capacity (W') works, and that we as coaches are on the leading edge of a training breakthrough. We'll be better able to help our clients understand how to handle any ride, any challenge, any hill, any climb, any long endurance ride, and any race condition, if that's where their spirit takes them. NO ONE, and I mean NO ONE, has applied this knowledge and information like we have, and I'm incredibly grateful for Drew Hartman, Philip Skiba, and all the other Scientists and Coaches who have brought us to this frontier.
