The unique ability of individuals living with T1D to influence their insulin concentration through exogenous administration necessitates greater planning and attention to optimise nutrition and insulin strategies for glycogen resynthesis. Understanding the physiology of glycogen resynthesis can help athletes with T1D manage the risk of hypoglycaemia and hyperglycaemia during recovery. The Physiology of Muscle Glycogen Resynthesis and Potential Implications for Athletes with T1D Muscle glycogen resynthesis begins immediately after exercise and is most rapid during the first 4 to 6 hours 60.<\/p>\n

This process occurs in two phases \u2013 insulin-independent and insulin-dependent \u2013 and each of them presents unique challenges: Initial Rapid Phase (Insulin-Independent): This phase occurs immediately after exercise and lasts minutes to hours (typically 30\u201360 minutes as observed in studies conducted on individuals without diabetes 61-63), facilitating rapid glycogen resynthesis without insulin. During this time, the muscles quickly take up glucose to replenish glycogen stores. The quantity (and intrinsic activity) of GLUT-4 transporters in the muscle membrane is still increased during this time, even though muscle contractions are not actively occurring anymore!<\/p>\n

While specific research on T1D athletes is limited 64, 65, it is reasonable to assume that, with adequate carbohydrate intake, this phase should proceed normally. Importantly, for athletes with T1D, insulin requirements may be lower in the first phase. This phase seems like a crucial window of opportunity for rapidly restoring glycogen stores for the athlete with T1D as no or less insulin is needed.<\/p>\n

Hence, a lower risk for hypoglycaemia could be assumed (if insulin administration is managed properly, of course). Notably, in endurance athletes with T1D, there might be a considerable overlap of the two phases regarding the need for insulin. Therefore, it might be reasonable to start more quickly with insulin during replenishment since it usually takes 15-30 minutes until insulin action starts.<\/p>\n

Hence, insulin boluses would need to be administered in the second half of the first rapid phase to allow optimal glycogen resynthesis in athletes with T1D. Still, athletes with T1D should be cautious not to overdose on insulin in this phase to avoid hypoglycaemia. Lastly, the resynthesis rate during this initial phase can quickly decline if exogenous carbohydrates are unavailable 63, 64. Long-Lasting Phase (Insulin-Dependent): This is a much longer phase, lasting up to 48-72 hours post-exercise, and mainly relies on insulin for glycogen storage 64.<\/p>\n

Insulin helps the muscles absorb glucose more effectively, supporting glycogen restoration. Without carbohydrate intake, this second phase occurs 7 to 10 times slower than the initial rapid phase 66, highlighting the importance of an adequate carbohydrate-fuelling regimen.<\/p>\n

We are exercise physiologists united by a shared passion for helping people living with type 1 diabetes (T1D) achieve their exercise goals. Over the past decade, our work has spanned clinical research, applied sports science with professional athletes with T1D, and technology start-ups.<\/p>\n

T1D presents unique challenges in exercise metabolism, making it difficult for those with the condition to exercise safely and effectively. While neither of us lives with T1D, our work has led to numerous close friendships, new insights, and a strong desire to improve the standard of care regarding exercise and T1D.<\/p>\n

This book is written for anyone interested in learning about the science of T1D and exercise. This includes people living with T1D, partners or caregivers of people with T1D, healthcare professionals, academics, and sports coaches. We also hope it can be a valuable resource for anyone studying exercise physiology and inspire more people to work in this area.<\/p>\n

There\u2019s still plenty to do! Through our experience, we have observed several key challenges related to exercise and T1D: Exercise continues to be one of the biggest challenges for many people living with T1D. Yet, it often receives less attention than other aspects of diabetes care. This lack of focus can negatively affect the quality of life and the sense of freedom associated with an active lifestyle. Healthcare professionals often find it challenging to provide sufficient guidance on exercise, particularly for those newly diagnosed with T1D or who wish to train or compete at high levels.<\/p>\n

Information from scientific research is not always accessible to people outside of clinical medicine or academia due to the complexity of academic language or journal access fees. In response to these challenges, we have compiled the most relevant research to help you better understand how to navigate the challenges of safe and effective exercise with T1D. This book begins with an overview and introduction to T1D and its implications for people living with it.<\/p>\n

We then provide a deep dive into exercise benefits, challenges, and management strategies (Chapters 2, 3, and 4). Chapter 5 discusses sports science principles and how they can be applied to endurance athletes with T1D.<\/p>\n<\/blockquote>\n
