Boxing is the only activity in which we have asked youth not to participate. In addition, the high incidence of brain damage makes boxing dangerous for people with or without diabetes. Fortunately, dangerous activities are not generally used for daily aerobic activity. The best time to exercise will vary with your schedule. Think ahead and make changes in insulin doses and snacks to help prevent low blood sugars.
Children like to play after school, and most organized sports activities take place then.
This is the time that most intermediate-acting insulins are having their main effect so that extra care to prevent low blood sugar is important. When possible, pick an exercise time, preferably the same time each day, and adjust the snacks and insulin dose to fit the exercise. If your urine ketone level is large or moderate, exercise can raise the sugar or ketone level even higher. Thus, it is not good for you to exercise when you have urine ketones. Remember to check urine ketones before exercising if you are not feeling well.
