For martial arts, extremely intense workouts will be more anaerobic in nature and may even cause an increase in blood glucose. But if you work out long and hard, your risk of delayed drops in blood glucose will be heightened by your depletion of muscle glycogen.

A Lumberton, New Jersey, resident, Chris Creelman takes a mixed martial arts fitness class at a jiujitsu gym. The workout is different every day, but it amounts to high-intensity interval training that includes a variety of weightlifting exercises, body-weight exercises, and cardio training (jogging, burpees, ladder climbing, sprinting, tire flipping, battle ropes climbing, and punching or kicking a bag). For this activity, if her blood glucose is 100 mg/dL (5.6 mmol/L) or lower before starting, she adjusts her basal rate down to 50 percent for 2 hours. If higher than 200 mg/dL (11.1 mmol/L), she gives herself a small bolus to bring her glucose down but then lowers her basal rate after training by half for the first hour after her workout.

For tai chi chuan participation, American Christopher Gantz reduces his dinner bolus by half (he uses regular insulin because he is on a high-protein diet). He eats his normal dinner before working out because the class is in the evening. He would prefer, however, to exercise without any active insulin in his system whenever possible.

PHYSICAL EDUCATION CLASSES AND GYM (SCHOOL BASED)

School physical education (PE) activities can vary widely, depending on which sport or activity (e.g., basketball, soccer, running, dance, or health instruction) the PE instructor is focusing on for the day or week. These activities may be done indoors or outdoors, depending on the weather, available facilities, the nature of the sport, and other factors. Not all schools offer PE classes daily anymore, making their effects even more unpredictable at times. Because these classes are so variable, compensating for the activities in advance can be difficult. Your best bet may be to make sure that you have carbohydrate snacks available to eat before and during more intense activities to prevent low blood glucose. Adjustments may need to be made on a daily basis to compensate for different activities done in PE and gym classes.

WALKING AND RACE WALKING

Walking is an endurance activity that uses your aerobic energy system. Your body uses fat and carbohydrate when you walk at a moderate pace, but it uses carbohydrate (both blood glucose and muscle glycogen) almost exclusively for brisk and race speeds. How long you walk will also make a difference, and you may need to alter your insulin, diet, or both for longer walks at certain times. For additional ideas, refer to hiking in chapter 12.

General Adjustments by Diabetes Regimen

Because walking is such a common activity for everyone, an outline of some general recommendations for walking and hypoglycemia prevention for specific groups is useful.

Insulin Pump Users

If you use a pump, you have the most flexibility in lowering your insulin levels because you can suspend or reduce basal insulin when walking, giving you the most normal physiological response. If
