Electrolytes are essential elements for maintaining hydration, muscle contraction of nerve conduction and blood pH balance. Under extreme temperature conditions or during intense exercise, many electrolytes are lost by exhalation and perspiration. Significant loss is also observed in case of diarrhea. Failure to make proper replenishment through nutrition or supplementation causes dehydration of the body, feeling intense weakness and cramps. It is recommended to administer them before and during the races to prevent dehydration and then to replenish the lost electrolytes.
