Pickle juice may help lessen muscle cramps in athletes, according to Picklelicious. The juice includes salt, vinegar, water and calcium chloride. It may help replace salt and other electrolytes lost when athletes sweat during exercise, notes student research from Vanderbilt University.
Anecdotal evidence indicates that the juice, which is combined with cucumbers to make pickles, has helped professional football players lessen cramping when competing in hot weather, the Vanderbilt University research notes. Despite claims of pickle manufacturers, little scientific evidence supports the use of the juice as an athletic drink to prevent muscle cramps and dehydration. Salt can help with dehydration but does not have to come from pickle juice, according to the director of the Sports Medicine Center at Vanderbilt University.
