| Research Abstract |
Whole-body fat oxidation was not always consistent with intramuscular fat oxidation. The aim of this study was to test whether hypoxia-decreased whole-body fat oxidation was intracellular lipid (IMCL) oxidation. Endurance runners performed 90-min running tests in normoxia and hypoxia. Compared with normoxia, hypoxia decreased not only whole-body fat oxidation, but also IMCL oxidation. These results suggest that decrease of whole-body fat oxidation in hypoxia is partly attributed to that of IMCL oxidation.
