Table 1 Represents metabolic and function data during the 3rd and fourth minute of contraction. Muscle oxygen consumption (VO2) units are ml O2 min-1 100 g-1 wet tissue and value represents the arterial-venous oxygen content difference multiplied by blood flow. Oxygen (O2) and Carbon dioxide (CO2) units are ml/DL where 'art' = arterial and 'Ven' equal venous. Sat = Saturation. Tension produced is kg 100 g-1 wet tissue at 3 min into the stimulation protocol. Muscle lactate efflux value represents the venous-arterial [lactate] difference multiplied by blood flow. Venous blood sampling was initiated at the 3rd minute and took appropriately 30 sec to obtain.
