*3.6. Erythrocyte O2 Release Capacity in Hypoxia Conditions*

O2 was released immediately (O2 pressure-diff was positive) from erythrocytes when erythrocytes were added to the hypoxia chamber, and the magnitude of release was further augmented due to the GXT (Figure 5G,L). An enhanced release velocity was also noticed (Figure 5J). After training, although no alternation in the oxygen release amount was observed at rest or even after the GXT, a faster velocity was observed in both the CCT and ECT groups under 0, 1 and 4 mM lactate acid (Figure 5J,K).
