Research summary
It is currently not known how Dexcom G6® and FreeStyle® Libre 2 perform around different types of exercise and different glucose ranges. An initial question would be to compare the performance of the Dexcom G6® and FreeStyle® Libre 2 to EKF references values during exercise. This information would be crucial for people with type 1 diabetes (T1D) and their healthcare providers when they strive to increase physical activity. In light of this, this study would aim to examine the accuracy in comparison of Dexcom G6® and FreeStyle® Libre 2 to EKF references values before, during and after high-intensity interval exercise (HIIE) and continuous exercise (CE) and different glucose ranges in individuals with T1D.
The null hypothesis is that there will be no differences in exercise-induced changes in glucose levels in comparison of Dexcom G6® and FreeStyle® Libre 2 to EKF references values before, during, and after HIIE and CE exercises and different glycaemic ranges.
Adults with type 1 diabetes on multiple daily injections will be invited for trial visits at a clinical research facility in Swansea University. The participants will attend 4 visits; screening for eligibility, 2 experimental visits with 90 mins of HIIE or CE and regular blood samples, and a follow-up visit.REC name
