Abstract
A study was made of breath-to-breath oxygen transfer at the alveolar-capillary membrane, cardiac output, and peripheral oxygen uptake during the first 5 min of treadmill exercise and recovery in normal human subjects. Oxygen transfer and cardiac output were measured directly; peripheral oxygen uptake was derived from these with the aid of a mathematical model. During exercise all three parameters had a very rapid initial rise, slower secondary rise, and achieved a steady state in 1.5-3 min. Recovery period responses were similar but slightly slower.This publication has 3 references indexed in Scilit:
