Cramps are one of the most frustrating issues in sport. They arrive without warning, disrupt performance, and often leave athletes feeling like all their preparation was wasted. For performance nutritionists, preventing cramps is a balancing act that blends preparation, fuelling, hydration, and in the moment solutions.
Understanding Why Cramps Happen
The latest research has shifted how we understand cramps. For a long time they were thought to be caused by dehydration and electrolyte loss. But studies like those reviewed by Giuriato and colleagues show that this is only part of the picture.
The stronger evidence points to neuromuscular fatigue. Muscle spindles and Golgi tendon organs send opposing signals to the nervous system. When fatigue sets in, the balance tips toward over excitation. Motor neurones fire uncontrollably, and the muscle locks into a cramp.
This is why cramps are most common in the closing stages of matches or races when the body is under its greatest stress.
Nutrition Strategies Before Competition
Preparation is everything. What an athlete eats and drinks in the twenty four to forty eight hours before competition can lower the risk of cramps.
-
Ensure carbohydrate availability is high enough to fuel performance and delay fatigue. This means balanced meals with complex carbohydrates the day before and appropriate fuelling in the hours leading up to competition.
-
Encourage adequate sodium intake alongside hydration. While cramps are not purely about electrolytes, low sodium status can still contribute to early fatigue.
-
Promote meals rich in magnesium and potassium as these minerals support normal muscle contraction. Foods like leafy greens, bananas, potatoes, and nuts are easy inclusions.
-
Support glycogen storage with pre match meals that combine carbohydrates and a moderate amount of protein.
Hydration Protocols
Hydration strategies should be individualised but there are general principles that help reduce cramp risk.
-
Begin competition well hydrated by monitoring urine colour and pre weigh ins.
-
Replace fluid losses steadily rather than over consuming just before kick off or race start.
-
Encourage athletes to include sodium containing fluids where appropriate to support fluid retention and limit excessive losses.
Hydration is not a cure for cramps, but poor hydration status can add another layer of stress on the body.
In the Moment Solutions
Even the best preparation cannot eliminate cramps entirely. When they strike, the key is having a fast and reliable response. This is where pickle juice stands out.
Miller and colleagues demonstrated that pickle juice relieves cramps far too quickly for it to be explained by electrolyte replacement. The mechanism is neurological. The vinegar base activates TRP channels in the mouth and throat, which in turn calm the overactive motor neurons causing the cramp. Relief comes within minutes.
This makes pickle juice a practical sideline tool. It complements long term fuelling and hydration strategies by giving athletes a way to get back into play without losing critical minutes.
Building a Complete Protocol
For performance nutritionists, the goal is integration. The best game day approach combines:
-
Pre competition meals that fuel muscles and nervous system function
-
Hydration strategies that maintain fluid balance and sodium status
-
In game fuelling that sustains energy and delays fatigue
-
Rapid cramp solutions like pickle juice when fatigue finally tips the system over
This layered approach allows athletes to perform at their peak with fewer interruptions from cramps and faster recovery afterwards.
Final Thought
Cramps are not only a physical problem, they are a performance problem. They cost athletes time, focus, and in some cases, entire competitions. By using a structured nutrition and hydration plan, supported by targeted interventions like pickle juice, performance nutritionists can give athletes the best possible protection.
