Overview

In the Czech Republic, thanks to the well-adjusted reimbursement by insurance companies, there is already an overwhelming prevalence of insulin pumps in the form of hybrid closed-loop systems (one can meet the abbreviations HCL – Hybrid Closed-Loop or AID – Automated Insulin Delivery) and pumps without automatic functions (so-called CSII – continuous subcutaneous insulin infusion or also open-loop systems) are gradually disappearing. HCLs have brought better control and greatly facilitated treatment management, including physical activity, to the lives of people with type 1 diabetes. Despite rapid development and continuous technical improvements, it is still necessary to announce meals to the pump (pre-bolus) and inform it about planned physical activity. It is also still necessary to account for the delay in glucose between blood and interstitium (sensor). For sports, it is good to have the pump set up correctly, to know how its algorithm works and to know the strategies to maintain normoglycemia. Without this knowledge the pump works well, but the joy of sport can be spoiled by fear of hypoglycemia, fluctuating values or often excess carbohydrate intake [1].
