I have ran con vo2max testing with moxy, I see a little difference when running a vo2max test since mask restrict a little the air flow, also psychological factor of some clients that feels they can breath freely with the mask. I didn't have any numbers but I see some differences.

Another question, how do you calculate the total volumen of oxygen that is use for the metrics.

Thanks a lot, a great webinar, I feel this is a great tool for athlete development

Richardson et al have concluded that: ‘‘…intracellular pO2 remains constant during graded incremental exercise in humans (50–100% of muscle VO2max)’’ so that: ‘‘With respect to the concept of the ‘‘anaerobic’’ threshold, these data demonstrate that, during incremental exercise, skeletal muscle cells do not become anaerobic as lactate levels suddenly rise, as intracellular pO2 is well preserved at a constant level, even at maximal exercise’’ (p. 63168). They also conclude that: ‘‘Net blood lactate efflux was unrelated to intracellular pO2 across the range of incremental exercise to

exhaustion’’ but was ‘‘linearly related to O2 consumption’’ (p. 62768). Another study confirmed these conclusions: ‘‘…consequently these data again demonstrate that, as assessed by cytosolic oxygenation state (deoxy-Mb) during incremental exercise, skeletal muscle cells do not become ‘‘anaerobic’’ as lactate levels rise, because intracellular PO2 is well preserved

at a low but constant level even at maximal exercise’’
