If so, then I do understand what you're saying... otherwise, you lost me on that one!
I'm thinking this entire thread just goes to show how many different, yet effective, ways there are to work out and interpret protocols!

What's happening in oxygen-dependent glycolysis is that the intensity is low enough for oxidation to play a role in glycogen re-synthesis. It's still being fueled by glycogen stores and is thus anaerobic, but oxidation is helping to refuel things.
This pathway actually contributes to a lot more than people realize, and it's a grey area between pure aerobic/oxidative metabolism and pure anaerobic glycolysis.
