Figure 1From: Metabolic adaptations to repeated periods of contraction with reduced blood flow in canine skeletal muscleSkeletal muscle oxygen consumption measured at rest and during the 3rd to fourth minute of contraction (this is when a venous blood sample was obtained). Oxygen consumption was calculated from the arterial-venous difference (oxygen content) and muscle blood flow. Oxygen consumption during contraction did not differ across the 4 stimulation periods. The black bars at the top of the graph represent the period of muscle stimulation.Back to article page
