Fig. 3

Averaged values every minute are plotted over a 11- to 20-min period after hypoxic gas exposure. Relationship between \( \dot{V}_{\text{E}} \) and \( \dot{V}{\text{O}}_{ 2} \) (a, c) and \( \dot{V}_{\text{E}} \) and \( \dot{V}{\text{CO}}_{2} \) (b, d). Distribution areas of variables in the fed (open symbols) and fasted (closed symbols) states are surrounded by circles. Note the relationship of the position in each circle
