What the book covers (themes & key ideas)

The science of exercise and diabetes - Colberg explains how different types of activity (aerobic, anaerobic, strength, interval training) affect blood glucose. She covers why aerobic exercise often lowers glucose, why anaerobic or high-intensity exercise may raise it, and how to anticipate and adjust for these effects.

Insulin and exercise adjustments - The guide includes detailed advice on modifying basal and bolus insulin before, during, and after activity, timing carbohydrate intake, and using CGMs and pumps to monitor and adapt in real time.

Fueling and nutrition - Strategies for fueling workouts safely, including carb loading, mid-workout snacks, and post-exercise recovery. Special emphasis is placed on balancing energy needs with blood sugar stability.

Specific sports and activities - One of the book's standout features is its 165 activity-specific chapters. From mainstream sports (running, cycling, swimming) to niche pursuits (rock climbing, martial arts, snowboarding), Colberg offers tailored guidance for managing diabetes during each.

Safety and prevention of complications - Covers hypoglycemia prevention, hydration, temperature regulation, injury risks, and safe participation in endurance or extreme sports.

Voices of athletes - The book includes personal stories from athletes living with diabetes, reinforcing that with preparation and flexibility, anything is possible.

What's excellent about this book

Unmatched scope: The activity-by-activity breakdown makes this the most detailed sports guide for people with diabetes.

Scientific credibility: Written by a leading exercise physiologist specializing in diabetes.

Actionable strategies: Specific tips for adjusting insulin, carbs, and hydration are easy to apply.

Empowering: Reinforces that diabetes does not limit athletic potential.

Where you'll want to supplement

Not beginner-focused: Families just learning the basics of T1D may find the details overwhelming; best after foundational education.

Geared toward self-managing athletes: Parents of young children will need to adapt concepts with clinical guidance.

Some content leans toward adults: While useful for teens in organized sports, parts of the book assume adult independence.

Parent-ready guide (inspired by the book)

How parents/athletes can use it:

Pick sports-specific chapters: Use the relevant sections when your child joins a new activity (e.g., soccer season, swim club).

Plan ahead: Read sections before major events (tournaments, long races) to map out insulin/carb strategies.

Build athlete independence: Older kids and teens can use the book themselves to learn how to manage their diabetes during sports.

Practical takeaways:

Every sport is different: Learn whether it tends to lower or raise glucose, then plan insulin/carb strategy.

Experimentation is key: Start conservatively, track patterns, and adjust over time.

Preparation prevents problems: Always carry supplies: fast carbs, hydration, backup insulin delivery.

Note: This is general information, not medical advice. Always confirm adjustments with your care team.

How this book fits among other trusted resources

Best for: Athletes of all ages (teens through adults) with T1D or T2D, and parents of children heavily involved in sports.
