Internal Training Load Measurement with Muscle Oxygenation

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

Speculating on Physiology in the Lab vs on the Road

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.
