People with T1D should ideally perform at least 150 minutes of moderate-intensity or 75 minutes of vigorous-intensity aerobic activity per week and 2–3 resistance exercise sessions, with no more than two consecutive days without activity to increase insulin sensitivity and lower the risk of cardiovascular disease.[1]
The glycemic response to exercise is highly variable and is affected by baseline fitness status; the type, intensity, and duration of exercise; the amount of insulin in circulation; preexercise blood glucose level; and preexercise meal composition.[2] As such, special care needs to be taken with respect to carbohydrate intake and insulin delivery around exercise to prevent hypoglycemia.
