What does eating mustard have to do with stopping muscle cramps during a run? Does it even work?

Mustard, a condiment often associated with hot dogs and sandwiches, may hold an unexpected benefit for athletes: relief from muscle cramps during a run. According to a Canada-based triathlete and trainer named Sammie, she witnessed a competitor suffering from a severe cramp during a half-Ironman event. Instead of handing her a sports drink or banana, the medical team provided a pack of mustard, which the competitor consumed. To her surprise, her cramp subsided and she was able to continue running at nearly the same pace.

Although mustard has not been scientifically proven to be an effective cramp treatment, it may work due to its neural mechanism. When consumed, mustard contains acetic acid and isothiocyanates, which can stimulate sensory receptors in the mouth and throat. These receptors, known as transient receptor potential (TRP) channels, may influence nerve activity involved in muscle cramps. However, the clinical pathways and exact mechanisms are not yet certain.

While mustard may be a helpful home remedy for night calf cramps, it should not replace sports drinks and bananas, which provide essential hydration and electrolytes. Dr. Ong Joo Haw, a sports physician, explained that mustard's effectiveness may depend on the pungency of the mustard. Stronger-flavored mustards like English mustard might be more effective than milder options like honey mustard.

Sami recommends trying different types of mustard before using it during a race, as different varieties have varying levels of pungency. It's also important to consider individual tastes and preferences to avoid unpleasant experiences during a race. Mustard should be viewed as an optional remedy rather than a proven sports nutrition solution. For best results, continue practicing proper stretching and hydration techniques in addition to trying mustard as a potential cramp-relief option.
