For a person with type 1 diabetes, participation in exercise may increase the risk of
hypoglycaemia. Research has been performed during or immediately after exercise in a
laboratory environment, with limited evidence regarding strategies for post-exercise
hypoglycaemia prevention.
The aim of this study was to investigate the occurrence of delayed hypoglycaemia after
40 minutes of moderate intensity exercise at 70% VO2 max before the evening meal, in both
the real-life and laboratory exercise environments.
Nine individuals (five males, four females) with type 1 diabetes using basal bolus
analogue insulin regimens participated. All performed two sessions of 40 minutes of moderate
intensity exercise in two environments (laboratory and real-life), while following a selfmanagement
algorithm that included a 30% reduction of post-exercise evening meal insulin.
Data were collected by continuous glucose monitoring for episodes of interstitial glucose
