Today's true sports drinks are still the classic Gatorade -- packed with the electrolytes potassium, magnesium, calcium, and sodium to provide energy during intense workouts -- as well as competitors such as Cytomax, Allsport, and Accelerade.
Performing one or several stretches which elongate the muscles in the affected area should help to provide quick relief. Stand up straight, and then get into a lunging position, with your back leg being the one experiencing the charley horse. Straighten out your back leg while keeping your front leg bent.
A number of factors may cause a muscle to cramp or spasm. The most common causes of charley horses include: 1  inadequate blood flow to the muscle. 2  muscle injuries. 3  exercising in excessive heat or cold. 4  overuse of a specific muscle during exercise. 5  stress (most often in the neck muscles). 6  not stretching before exercise.
