Why Do Footballers Cramp? What Causes It and What Players Use for Cramp

Why do footballers cramp? And why always in the 80th minute, right when the game's on the line?

Short version: cramp is mostly a tired-muscle problem, and water is only part of the story. Below is what the research says, how players stop a cramp, what they actually use (pickle juice included) and how to prevent the next one.

The Short Answer

What a Cramp Actually Is

A cramp is a sudden, painful tightening of a muscle that won't let go, usually the calf, hamstring or quad. Researchers call it an exercise-associated muscle cramp (EAMC), meaning it happens during or right after exercise.

The soreness that builds a day or two after a game is different. That's DOMS. A cramp hits in seconds and usually passes in minutes.

Why Do Footballers Cramp? The Two Main Theories

For most of the last century, the go-to explanation was "you're dehydrated and low on salt." The research has moved on. There are two leading theories, and a 2018 review comparing them concluded the neuromuscular one "may prevail" (Giuriato et al., 2018).

The neuromuscular fatigue theory

This one came out of the University of Cape Town. In 1997, Martin Schwellnus and colleagues proposed that a fatigued muscle's reflexes go out of balance (Schwellnus et al., 1997). The sensors that tell it to contract (muscle spindles) fire more, the ones that tell it to relax (Golgi tendon organs) fire less, and the muscle gets stuck "on."

The field evidence fits:

• In 72 ultra-distance runners, those who cramped weren't more dehydrated or low on electrolytes (Schwellnus et al., 2004).
• In 210 Ironman triathletes, the only independent predictors were racing faster and a history of cramping, not weight loss or blood sodium (Schwellnus et al., 2011).

It also explains why stretching works: it loads the tendon sensors, which tell the muscle to switch off.

The dehydration and electrolyte theory

The older theory says heavy sweating drains fluid and sodium until nerves misfire. It isn't dead. A 2019 review says some cramps do seem linked to water and salt balance, others to fatigue, so there are probably different types of cramp and no single fix (Maughan & Shirreffs, 2019).

A 2022 evidence review agrees: cramps come from a mix of factors, and prevention should fit the player rather than generic "drink more" advice (Miller et al., 2022).

What Makes Cramp More Likely in a Football Match

Football is 90 minutes (sometimes 120) of sprints, jumps and changes of direction, exactly the work that tires muscles out.

So why do soccer players cramp so much? A long match, lots of explosive efforts, tired legs in the last half hour, and often heat on top.

How to Stop Cramp on the Pitch

The best-supported fix is simple: gently stretch the cramping muscle and hold it until it eases (Miller et al., 2022).

1. Stop and signal. Don't try to run it off.
2. Stretch the muscle that's cramping, gently (see the table).
3. Hold until it lets go, usually seconds to a couple of minutes. Ease off if it hurts more.
4. Massage lightly if it helps. Standing on the leg can help too (NHS).
5. Sip something: water, a sports drink or pickle juice (more below).
6. Get up slowly. Walk and jog before you sprint again.

Cramp keeps coming back? Your body is telling you it's done for the day. Coming off is the smart call.

What Do Footballers Use for Cramp?

Walk past any sideline and you'll see a bit of everything. Here's how much evidence is behind each.

One catch: a shot of pickle juice doesn't rehydrate you. In a follow-up, it didn't change blood sodium or potassium within an hour (Miller, 2014). It's a quick reflex, not a refill. And as the 2019 review puts it, of all the folk remedies, "none are consistently effective" (Maughan & Shirreffs, 2019).

How to Prevent Cramp in Football

Since fatigue is the main driver, the best prevention is being fit enough for the minutes you play.

• Build match fitness gradually. Preseason and comebacks are high-risk, so increase minutes step by step.
• Warm up properly, with some sprints and jumps.
• Arrive hydrated. Drink through the day before kick-off rather than chugging at the whistle.
• Plan for heat. Use every drinks break, and add electrolytes on hot days.
• Know if you're a salty sweater. White marks on your kit are a hint. Ask a sports dietitian about sodium.
• Fuel for 90 minutes. Low glycogen goes with late-game fatigue (Mohr et al., 2023), so eat carbs before the game.
• Know your history. Cramp often? Tell your coach. A planned substitution beats a forced one.
• Recover between games. Sleep and food come first.

Heat, Humidity and Winter Pitches

Where you play changes the risk.

• Nigeria and Kenya: afternoon kick-offs in the heat mean bigger sweat losses and faster fatigue. Take it seriously if a cramp comes with dizziness or nausea.
• Singapore: humidity makes it harder for sweat to cool you, so you heat up faster.
• South Africa: summer football in humid Durban is a heat game.
• UK winter: cold doesn't make you cramp-proof. Heavy, muddy pitches make every sprint harder, and tired legs cramp in any weather.

The FIFA World Cup 2026 used three-minute hydration breaks in each half of every match (FIFA). FIFPRO, the players' union, recommends cooling breaks when the heat index (WBGT) passes 26°C (FIFPRO).

When to See a Doctor

Most cramps are harmless and gone in minutes. The NHS says to see a GP (doctor) if:

• a cramp lasts longer than 10 minutes
• you also have numbness or swelling in the leg
• cramps keep disturbing your sleep

Some medicines, like statins and diuretics, can cause cramps too, so mention any new medication.

Where Carnosine Gel Fits (Honestly)

Let's be straight with you: no study has tested carnosine gel for cramps. Not one. So we can't say it prevents or stops them, and be wary of anyone who does.

What has been studied is performance. Small studies in soccer and rugby sevens players reported some sprint benefits (the soccer one had no placebo), and two cycling trials found none (Sharpe & Macias, 2016; Beaven et al., 2025). None measured cramps. Our review of every carnosine gel study grades them all.

So where does it fit? Some athletes simply include a carnosine gel like LactiGo in their pre-match routine, alongside the warm-up, fluids and fueling above. LactiGo's directions say about 30 to 45 minutes before activity (put it on while you're changing). See how to use LactiGo. It contains magnesium too, but that isn't evidence it helps cramps.

The Bottom Line

Footballers cramp mostly because their muscles are tired, which is why it shows up late in games and in players who've cramped before. Heat and salty sweat can add to it.

Stretch it out when it hits. Get fit for the minutes you play, drink and fuel early, and have a plan for hot days. Pickle juice might shorten a cramp, but it won't replace any of that.

Frequently Asked Questions

Why do footballers cramp so much?

Ninety minutes of sprints and jumps tires muscles out, and the leading theory is that fatigue upsets the reflexes that control a muscle. Heat, heavy sweating, low fitness and past cramps make it more likely.

How do you stop cramp in football quickly?

Stop and gently stretch the cramping muscle until it eases. For a calf cramp, straighten the knee and pull the toes toward the shin. Walk and jog before you sprint again.

What do footballers use for cramp?

Mostly stretching, plus water, sports drinks, pickle juice or spicy "cramp shots." Some salty sweaters add salt in the heat. None works every time.

Does pickle juice work for cramp?

In one lab study, about 75 mL ended electrically induced cramps around 49 seconds sooner than water, before blood electrolytes changed. It seems to be a reflex, not rehydration, and the cramps were lab-induced, not from match play.

How do you prevent cramp in football?

Build match fitness gradually, warm up, arrive hydrated, fuel with carbs, add electrolytes on hot days and know your cramp history. Experts recommend tailoring prevention to the player.

Does carnosine gel or LactiGo help with cramp?

No study has tested carnosine gel for cramps, so we can't say it does. Some athletes include it in a pre-match routine, about 30 to 45 minutes before activity per LactiGo's directions.

Can I buy LactiGo in Nigeria, Kenya, South Africa, the UK or Singapore?

Not directly yet. The official store ships to the US, Canada and Australia (US$25 flat to Australia). Direct shipping elsewhere is coming soon.
