instability related to exercise in people with type 1 diabetes mellitus is most often studied using short-term labo-ratory investigation. However, such acute laboratory ses-sions do not provide an “everyday ” depiction of the frequency of blood glucose excursions during training. Continuous glu-cose monitoring systems (CGMS) provide a unique method of observing both the immediate and long-term effects of exercise on glycemic control in this active population. The purpose of this observational study was to quantify episodes of both hypo- and hyperglycemia during a 5-day training camp for athletes with type 1 diabetes. Twelve subjects from the Diabetes Training Camp were ran-domly selected and fitted with CGMS and were instructed to maintain their usual insulin and blood capillary sampling regimens for exercise.
