What happens to athletes who change their electrolyte levels when exercising?

When athletes alter their electrolyte levels during exercise, it can significantly impact their performance and overall health. An imbalance, such as low sodium or potassium, can lead to muscle cramps, fatigue, or even more severe conditions like hyponatremia. Conversely, excessive electrolyte intake can cause gastrointestinal distress or hypernatremia. Therefore, maintaining proper electrolyte balance is crucial for optimal athletic performance and safety.
