Electrolytes
It’s essential to replace electrolytes after exercise lasting longer than an hour, exercise in the heat, or any strenuous exercise. Many people don’t know what electrolytes are or how they affect the body.
The main types of electrolytes are sodium, potassium, calcium, magnesium, chloride, and phosphate. In order for the body to function it must have the proper balance of electrolytes. The purpose of electrolytes is to transport fluid from one cell to another keeping the body hydrated, regulating blood pH, and allowing the muscles and nerves to function properly.
Most electrolytes are replaced in adequate amounts by eating a balanced diet. If the body gets to many electrolytes they are flushed out, if it gets to few it can’t function properly impairing performance. The main electrolytes that need to be replaced during exercise are sodium and potassium. For exercise lasting a short time water is fine, but for anything longer or in a hot environment a sports drink or electrolyte replacement drink should be used. Water and electrolytes need to not only be replaced during training but afterwards as well. Also, if you have been sick or are dehydrated, electrolytes should be replaced along with water.
