Why the study?
Non-invasive methods to determine muscle O2 diffusing capacity in humans are currently unavailable.
Does NIRS estimation of muscle oxygen uptake recovery rate constant correlate with muscle oxidative capacity and capillary density in humans?
Does NIRS estimation of muscle oxygen uptake recovery rate constant correlate with muscle oxidative capacity and capillary density in humans?
NIRS provides a non-invasive method to assess both muscle oxidative and oxygen diffusing capacity in vivo.
No takes yet. Share an insight, caveat, or question.
NIRS-derived kHIGH was associated with muscle oxidative capacity; hypothesis-generating for non-invasive assessment pending prospective validation.
