Oxygen Deficit and EPOC consumption during steady state exercise

at low and high intensity.

Introduction:

Previous research has shown that in the transition from rest to light or moderate exercise, The body's oxygen requirements increase the moment exercise begins and reaches steady state within 1-4 mins, depending on factors such as intensity of the exercise and participants training status (Powers and Howley, 1994; Martin, 1974). Therefore because oxygen requirements and oxygen supply differ during the transition from rest to exercise, the body incurs an oxygen deficit. (Powers and Howley, 1994) described the term 'oxygen deficit' to apply to the delay in oxygen uptake at the beginning of exercise, and has been defined as the difference between oxygen uptake in the first few minutes of exercise and an equal time period after steady state has been obtained.

Figure 1. This table shows EPOC and Oxygen Deficit.

Krogh and Lindhard (1919) stated that the deficit at the beginning of exercise and recovery oxygen after exercise were essentially equal in size.

Hill and Lupton (1923), stated that during the initial minutes of recovery, even though your muscles are no longer actively working, oxygen
