The aerobic energy system is “broken” in ME/CFS and cannot be fixed with exercise (i.e., graded exercise therapy, also known as GET).
The anaerobic (glycolytic) system appears to be somewhat functional in ME/CFS (but see McGregor’s work) and, in theory, can be trained to be more efficient with a carefully-designed exercise protocol done under the guidance of an ME/CFS-literate physical therapist.
It is vitally important to avoid spending time above the anaerobic threshold, also known as “AT”.
It is also advisable to minimize the duration of aerobic activities, including cognitive tasks.
If the points above appear to contradict each other, in a sense they do! But a well-designed pacing program can minimize the negative effects of both aerobic and anaerobic metabolism while at the same time harness the benefits of each energy system.
