This study examined changes in interstitial PO , which allowed calculation of VO during periods of rest, muscle contraction and recovery using an rat spinotrapezius muscle preparation. The PO was measured using phosphorescence quenching microscopy and the muscle VO was calculated as the rate of O di...
