Time course of glucose, FFA, and lactate levels during 5 h of 10% O₂ SH or IH (ODI 60). Glucose was elevated by both forms of hypoxia, with the greatest increase observed in the first 2 h (P < 0.05 for ODI 0 vs. ODI 60 and SH for the 1.5-h time point). A similar early rise in FFA was observed during IH (P < 0.05 for ODI 0 vs. ODI 60 at the 1.5- and 3-h time points). SH decreased FFA relative to the other conditions at 5 h (P < 0.01). Lactate was increased only by SH (P < 0.05 for SH vs. other groups at 1.5-, 3-, and 5-h time points).
