How accurate is your gadget of choice at predicting your individual response to exercise? How close is that V̇O₂max estimate from your sport watch? How close was the predicted race time to your real results? How far apart are your FTP/threshold estimates between a ramp test, a 20 minute test, and a 60 minute time-trial? … Continue reading Interpreting Group-Level Data for Individual-Level Application
Here is a brief summary of our recent paper from the University of British Columbia Environmental Physiology Laboratory authored by my colleague Dr. Assaf Yogev and our colleagues. We think this is a paper that athletes & coaches can use to help understand uncertainty in performance data collection. The results here can be used as … Continue reading Study Summary – Reliability of Common Cycling Performance Markers
Our hypothesis is that the linear extrapolation of PS SmO2 during the work stage can predict time to exhaustion, when performed to task intolerance. Across both male and female subjects, we have seen that in 27 of 36 trials, both the vastus lateralis and paraspinals oxygenation slopes provide a reasonable prediction of TTE.
The 5-1 assessment we run is a submaximal intermittent step test that uses NIRS and VO2 to identify physiological thresholds and training zones. I've mentioned it before. We use the general terms ‘Aerobic Threshold’ (AeT) and ‘Anaerobic Thresholds’ (AnT) for the first and second breakpoints respectively, and a polarized 3-zone model between these thresholds. The … Continue reading Comparing VO2 Master Pro to TrueOne 2400 – Part 2
Before my recent surgery I performed a whirlwind of self-testing to answer some pressing questions before being off the bike for a while. Now that I'm in recovery mode I'm working through all the data I collected and trying to write up the more interesting findings. I was able to perform an informal pilot study … Continue reading Comparing VO2 Master Pro to TrueOne 2400 – Part 1
