Energy continuum

FFA's produce more acetyl CoA than glucose, but require 15% more oxygen.

With aerobic training, there is an increase in liver and muscle glycogen stores, increased mobilisation of enzymes used in aerobic respiration, and earlier use of FFA's, helping to conserve glycogen.

The energy continuum is the constant changing and combination of energy systems used by the body, and it depends on the intensity and duration of the activity.
