The kinetics of the decrease in venous O(2) content in response to constant work rate exercise below the lactic acidosis threshold (LAT) is very rapid, reaching a constant value by approximately 1 min. However, for work rates above the LAT, a slow further decrease in venous O(2) content takes place that is attributable to the Bohr effect rather than further decrease in end capillary PO. We hypothesized that similar differences, with respect to the LAT, will be observed in muscle deoxygenation kinetics when studied with near-infrared spectroscopy (NIRS).
