Acute hyperglycaemia does not have a consistent adverse effect on exercise performance in recreationally active young people with type 1 diabetes: a randomised crossover in-clinic study

Conclusions/interpretationAcute marked hyperglycaemia in the higher but not low insulin state impaired\( \dot{V}{\mathrm{O}}_{2\mathrm{peak}} \) but to a small extent. Acute hyperglycaemia had an insulin-dependent effect on sprint cycling absolute power output and reaction time but with differing directionality (positive for sprint cycling and negative for reaction time) and no effect on the other indicators of exercise performance examined. We find that acute hyperglycaemia is not consistently adverse and does not impair overall exercise performance to an extent clinically relevant for recreationally active individuals with type 1 diabetes.FundingThis research was funded by Diabetes Research Western Australia and Australasian Paediatric Endocrine Group grants.Graphical abstract
