Tag: Prolonged exercise

Up to 13% of marathon runners have experienced some degree of exercise-associated hyponatremia (EAH). This potentially fatal condition, characterized by low blood sodium, is primarily caused by overconsuming fluids, particularly water, during prolonged exertion. Understanding which intake prevents hyponatremia during prolonged exercise is crucial for athlete safety and performance.

After approximately 90 minutes of moderate-to-high intensity exercise, muscle glycogen stores can become significantly depleted, a phase commonly known as 'hitting the wall'. This triggers a critical metabolic shift, which is crucial for understanding what are the main sources of energy after 3 hours of exercise and how to properly fuel and recover.
