Electrolytes play a crucial role in athletic performance by maintaining hydration, muscle function, and nerve signal transmission. Key electrolytes, including sodium, potassium, calcium, and magnesium, help regulate fluid balance within the body. During intense exercise, electrolyte imbalances can lead to muscle cramps, fatigue, and decreased performance. Ensuring adequate intake of these minerals through diet or sports drinks is essential for athletes, especially during hot weather or prolonged physical activities. Proper electrolyte management supports optimal physical capabilities and enhances recovery post-exercise.
