A drink containing electrolytes, such as sodium and potassium salts, usually taken to replace mineral salts lost during sweating and to avoid heat cramps. Sodium salts are the most important electrolytes in these salt-replacement drinks. As exercise progresses, the salt content of sweat tends to decrease, proportionately more water is lost, increasing the salt concentration in the body. Therefore, electrolyte replacement without adequate water replenishment will increase dehydration and may adversely affect performance. See also energy drink.
