Introduction

Many people with type 1 diabetes (T1D) wish to be physically active and exercise regularly. However, exercising adds complexities to the already challenging task of daily glucose management. Chief among these considerations are insulin dose adjustments and the effects of meals surrounding exercise. Monitoring blood glucose levels during these times and establishing ideal glucose targets for safe and effective exercise is very important. This chapter addresses the unique challenges of managing blood glucose levels before, during, and after exercise, offering general tips and advice for exercise and glucose management.

 

Part 1. Tips and Considerations Before and During Your Workout

We’ve broken down this section into seven parts, each focusing on a key aspect of glucose management before and during exercise. Remember, these are general guidelines since everyone’s situation and needs may vary:

  1. Starting Blood Glucose Concentration: Check your glucose levels before exercising and understand how to interpret and act on these levels.

  2. Exercise Modality: Consider the type, intensity, and duration of exercise.

  3. Managing Insulin on Board (IOB): Make insulin adjustments as needed and account for insulin already delivered and active in your system.

  4. Nutritional Considerations: The impact of consuming carbohydrates and other macronutrients before and during exercise.

  5. Timing of Exercise: Consider the time of day you exercise and how it relates to the timing of meals.

  6. Impact of Previous Events or Activities: Consider any recent exercise or episodes of hypoglycaemia.

  7. Technology: Tools for monitoring blood glucose levels and managing insulin delivery.
