Brief Summary

Cardiometabolic risk in patients with abdominal obesity and type 1 diabetes can be moderated by life style modifications. There is an intimate link between gene regulation and circadian rhythm in mediating response to exercise in a variety of insulin sensitive organs. The aim of this project is to evaluate, by intervention, the interplay of circadian rhythm and high intensity interval training (HIIT) on glucose control and skeletal muscle metabolism in patients with overweight with or without type 1 diabetes (T1D).
