Figure 1. The 7 Key Factors to Consider for Exercise Planning and Glucose Management in People with T1D. This figure uses a puzzle metaphor to represent glucose management during exercise. The idea is that while there are some known key factors, many pieces of the puzzle are still missing, unknown, or difficult to measure. This approach visually communicates both the complexity and the challenge of exercise planning with diabetes. Note that the suggestions in this chapter are general recommendations and will, therefore, not apply to every scenario and individual.
