Electrolytes, including sodium, potassium, calcium, and magnesium, play a crucial role in sports performance. They are essential for nerve function, muscle contraction, and fluid balance. During intense physical activity, electrolytes are lost through sweat, which can lead to dehydration and performance decline. Replenishing electrolytes before, during, and after exercise is vital for maintaining optimal hydration, preventing cramping, and facilitating recovery, ultimately enhancing overall sports performance.
