Risks of Excessive or Mis- Timed Caffeine

Understanding Caffeine andd Blood Sugar: The Science

To manage caffeine effectively, ultra runners need to grapp it interplay with glucose homeostasis. Caffeine stimulates thee adrenal glands to release epinephrine, which triggers cogenelysis - thee breakdown of liver glogogegen into glucose. This raives blood sugar temporarily. In a rested state, this can cause a sharp spike followed a rebound, but during exerise, the working muscles rapfidly uptake thatt glucose, so the spike of.

Moreover, caffeine reduces insulin sensitivity for a short period, mening that te body requires more insulin to clear glucose from the bloostream. For non-diabetic athlets, this is usually nott a problem, but it can insecbate post- race recovery issues if caffeine is consumed after exercise.
