The need to administer exogenous insulin in type 1
diabetes mellitus (T1DM) subjects generally increases
the risk of exercise-related hypoglycemia. A better
understanding of exercise-associated fuel metabolism is
essential to develop strategies to improve glucose
stability. In this study two types of exercise protocols
(moderate (CONT) and high intermittent intensity (IHE))
were performed in T1DM subjects to evaluate glucose
requirements and hepatic and myocellular glycogen
consumption during the two different exercise
interventions. The IHE protocol provides a feasible
strategy to reduce glucose requirements during the
exercise. This is correlated with an increased
consumption of hepatic glycogen.
