Perception of Blood Sugar Variations During Physical Activity in Healthy Subjects and Type 1 Diabetes Patients

Type 1 diabetes is an autoimmune disease with absence of insulin secretion. Blood sugar is a physiological variable that reflets for blood glucose concentration. Blood sugar level fluctuates, especially during physical activity. Sports activity would increase insulin sensitivity, improve lifestyle and, by extension, promote glycemic balance. However, glycemic balance will be disturbed by physical activity with higher risk of hypoglycemia and hyperglycemia. Moreover, hypoglycemia and hyperglycemia will impact body functions. Perceptions of blood sugar variations during physical exercise and their influences on sports performance have not been studied, whether in type 1 diabetes patients or healthy subjects.
