A recent finding in our research with Moxy muscle oxygenation was looking at the reliability & repeatability of muscle oxygen saturation (SmO2) compared to heart rate for a typical high intensity interval workout. We had a group of well-trained male subjects (VO2max > 60 ml/kg/min) perform a series of 4x4min high intensity
For this experiment we wanted to look at physiological response to the same workout in the LAB vs in the FIELD. It's fascinating! There are a lot of conflicting and equivocal findings, ultimately suggesting that there is a high degree of individual variability in how each of us produce power across modalities and conditions.
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
