Electrolytes, such as sodium, potassium, and magnesium, play a crucial role in exercise by regulating fluid balance, muscle contractions, and nerve function. During physical activity, sweat leads to the loss of electrolytes, which can result in issues like muscle cramping, fatigue, or heat-related illnesses. Adequate electrolyte intake helps maintain muscle performance and hydration levels. Consumption of electrolyte-rich foods or drinks before, during, and after exercise is essential to replenish lost minerals and support overall performance and recovery.
