Soon WHK, et al. - In people with type 1 diabetes, researchers determined whether pre-exercise carbohydrate ingestion to maintain stable glycaemia during moderate-intensity exercises results in excessive hyperglycaemia in combination with repeated sprints. For this analysis, 8 overnight-fasted people with type 1 diabetes completed four 40-min exercise sessions on separate days in a randomized counterbalanced order under basal insulinaemic conditions: continuous moderate-intensity exercise at 50% V̇O₂ peak; intermittent high-intensity exercise; continuous moderate-intensity exercise with prior intake of carbohydrate; and intermittent high-intensity exercise with prior intake of carbohydrate. Findings revealed that adding repeated sprints was not significantly harmful to glycaemic management in overnight fasted people with type 1 diabetes under basal insulin conditions when carbohydrates were ingested before moderate-intensity exercise.
