To investigate the relationships between oxygen consumption (VO2) and the rates of systemic lactate appearance (Ra) and disappearance (Rd), six healthy males were studied at rest and during continuous graded exercise using a primed continuous infusion of lactate tracer. Subjects exercised for 6 min at 300, 600, 900, and 1,200 kg . m . min-1. L-(+)-[1-14C]lactate was infused intravenously, and arterial samples were drawn at rest and every 2 min throughout the exercise period. Ra and Rd were… CONTINUE READING
