Quick myth-buster for sports families: a cramp on the field usually means your athlete needs more salt....
The salt idea goes back to 1930s studies of laborers sweating through full shifts in extreme heat. When researchers tested athletes who cramped during marathons and Ironman races, their blood electrolytes and hydration were about the same as athletes who didn't cramp.
The bigger factor was fatigue. A worn-out muscle's nerves fire too much and relax too little, so it locks up, which is why cramps show up late in games and early in a season.
In the moment, a gentle stretch is the best-supported fix.
For prevention: steady fitness, real sleep, eating enough (and enough carbs!!) and drinking fluids through the day. Water and electrolytes still matter. It's just not the whole story.
Has your athlete dealt with cramps this season? What helped?
