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.
Drink water: A charley horse can be the result of dehydration or lack of water. Make sure you are getting the proper amount of water every day. Take vitamins: A lack of vitamin E or other vitamins can cause charley horses. Take a daily multivitamin or increase your intake of the right foods to get the daily vitamins you need. Try a mineral: Magnesium can also relieve charley horses. Add this mineral to your daily routine to help prevent charley horses.
