Delayed hypoglycaemia in people with type 1 diabetes after performing moderate intensity exercise before the evening meal

For a person with type 1 diabetes, participation in exercise may increase the risk ofhypoglycaemia. Research has been performed during or immediately after exercise in alaboratory environment, with limited evidence regarding strategies for post-exercisehypoglycaemia prevention.The aim of this study was to investigate the occurrence of delayed hypoglycaemia after40 minutes of moderate intensity exercise at 70% VO2 max before the evening meal, in boththe real-life and laboratory exercise environments.Nine individuals (five males, four females) with type 1 diabetes using basal bolusanalogue insulin regimens participated. All performed two sessions of 40 minutes of moderateintensity exercise in two environments (laboratory and real-life), while following a selfmanagementalgorithm that included a 30% reduction of post-exercise evening meal insulin.Data were collected by continuous glucose monitoring for episodes of interstitial glucos
