Recently, 10 healthy male college students filed into an exercise laboratory at Brigham Young University in Utah to drink pickle juice. Many people involved in sports are convinced that the briny fluid combats muscle cramping. In a 2008 survey, a quarter of the athletic trainers interviewed said that they regularly dispense pickle juice to cramp-stricken athletes. Many also report that, in their experiences, the stuff quickly brakes the cramping. The athletic trainers have told researchers that they believe the pickle juice must be replenishing the salt and fluids the athletes had lost to sweat. But no laboratory science had verified that theory.
10 is way too small a sample size to be taken seriously.
