Burnley & Jones 2007, oxygen uptake kinetics as a determinant of sports performance

Review in the European Journal of Sport Science (7(2):63-79). Sets out the phases of the VO2 on-kinetics response and the exercise-intensity domains (moderate, heavy, severe), and argues that the speed of the response, the VO2 slow component, VO2max and anaerobic capacity together determine exercise tolerance. Faster kinetics shrink the early oxygen deficit; above the lactate threshold a slow component raises oxygen cost, reducing efficiency and drawing more on muscle glycogen; in the severe domain no steady state is reached and VO2 rises to VO2max. Discusses how training and prior exercise (warm-up) speed the response. A review of controlled physiology.
