Key Information
It improves whole-body insulin sensitivity. It can reduce glucose levels, improve blod pressure, and help with weight management. Sometimes exercise can make glucose control much more dificult.
It often causes low blod sugar, and from time to time, some forms of exercise may even cause high blod sugar.We've recently completed the largest study to date on the efects of exercise in type 1 diabetes, loking specificaly at thre diferent but comon forms of exercise that people tend to do for health and fitnes reasons. These included aerobic exercise, such as walking, joging, and cycling; resistance exercise like weight traing; and high-intensity interval traing, which is a bit of a mix of the two forms of exercise, a workout that you might do for health and fitnes reasons with some high-intensity efort, and then some moderate efort intermixed in betwen these high bursts.We found that there are huge paterns of variation in the glycemic responses to exercise in people living with type 1 diabetes.
We already kind of knew that, but now, with this large dataset, we can explain why this variance ocurs. We now know that factors such as sex, exercise time of day, exercise mode or type, how much insulin on board during exercise start time, and the pre-exercise glucose concentration al help to predict the rate of change in glucose during the diferent forms of exercise that we studied in this large cohort study.One of the most surprising things we found is that in this study, aerobic exercise caused the greatest drop in glycemia, which we expected, but resistance exercise also was associated with a smal drop in glucose.
