Staying hydrated during exercise is very important and it is possible to lose up to 500ml of fluids in just half an hour. Electrolytes are minerals in the body and compounds that bind to them to create salts, such as sodium, potassium, magnesium, chloride, calcium, bicarbonate, phosphate, and sulphate. Light exercise in moderate climates, water without electrolytes is sufficient for most people. However, when running in warm climates or for prolonged periods important electrolytes are lost through sweat. Muscle cramps are one hint that electrolytes may be running low if you’re sweating a lot. Electrolyte tablets added to your water to sip during and after exercise will replace electrolytes
Recovery drinks are used after extensive workouts, to provide rapid energy for hungry muscles and to absorb proteins which help build and repair tired muscles.
