Competition Induced Hyperglycemia in Athletes With Type 1 Diabetes
Sponsor: University of Aarhus
Summary
Design and methods 12 athletes with T1D and 12 healthy athletes are included in a prospective experimental randomized, cross-over study. Athletes are provided with a Dexcom G6 CGM to measure glucose excursions before, during and after exercise and a Holter ECG-E-patch to measure HRV. Psychological stress levels are assessed from Competitive State Anxiety Inventory-2. The athletes are studied on two occasions: Day 1: 5K running competition and Day 2: 5K high intensity training session (running) in the athletes' regular training environment. Endpoints Primary endpoints: Change in plasma glucose from start of exercise to end of exercise during competition compared to training. Secondary endpoints: Hormonal response (cortisol, adrenalin, noradrenaline). Changes in heart rate and HRV before, during and after exercise. CGM-glucose and plasma glucose discrepancies.
