That doesn't sound right to me. Going anaerobic doesn't mean you don't use O2 - it just means that the energy in excess of what can be provided by the aerobic system has to be delivered by the anaerobic metabolism. Still, there may be other reasons why developing the anaerobic side comes at the expense of the aerobic end.
