Why are electrolytes important for physically active people?

Electrolytes are positively or negatively charged ions that conduct electrical activity. In the human body electrolytes must be present in proper concentrations to maintain fluid balance, muscle contraction and neural activity. The kidneys work to maintain electrolyte balance by conserving or excreting electrolytes. Water follows the movement of electrolytes, particularly sodium and chloride, meaning that water is drawn to locations where electrolytes are most concentrated. Therefore, electrolytes play a critical role in maintaining equilibrium of water throughout the body, particularly during exercise when electrolytes and water can be lost through sweating.

Do all electrolytes play an equally important role with regard to physical activity?

Electrolytes lost in high concentrations through sweat include sodium and chloride, while electrolytes lost in low concentrations include potassium, magnesium and calcium. Keep in mind that all electrolytes work together to maintain fluid balance in the body at rest and during physical activity.
