You are having the training session of your life when suddenly a cramp strikes. Feeling good is probably the last thing on your mind. Could knowing which foods may help reduce cramps make a difference?
Let’s explore the possibilities.
Why do muscle cramps happen?
First, what exactly is a muscle cramp, and why does it occur?
The causes are not fully understood, but potential factors include substantial muscle fatigue, dehydration and holding one position for a long time.
It is therefore unsurprising that cramps can appear during prolonged physical activity, including that otherwise excellent workout.
Does a cramp mean you are injured?
Before you start worrying about your next session:
An occasional cramp does not necessarily mean an injury. In general, muscle cramps are harmless and resolve after a few minutes.
If something feels wrong, stop and take a breath. Continuing despite pain could contribute to a more serious injury.
Which minerals matter for athletes?
As dehydration can be a factor, pay attention to mineral intake as well as fluids. Athletes can lose more sweat and therefore more electrolytes.
Training hard without sweating is certainly a challenge!
Minerals involved in exercise include calcium, sodium and magnesium, as well as potassium and zinc. Everyday meals provide these minerals, but sodium deserves particular attention because it is the main mineral lost in sweat.
What about muscle fatigue? It can also predispose you to cramps. Maintaining glycogen stores during intense exercise helps keep muscles fuelled. Plan carbohydrate intake around individual needs, exercise intensity and the rest of your daily meals.
Do you need electrolyte supplements?
Usually not for moderate activity. A personalised nutrition plan can cover daily mineral requirements, making supplements unnecessary unless a particular deficiency has been identified.
Sodium needs attention because substantial amounts can be lost in sweat, especially during long-duration sports, high-intensity activity or hot conditions.
Sweating causes electrolyte loss, but excessive fluid intake is also a danger: drinking beyond your needs can dilute blood sodium and lead to hyponatraemia. Adding electrolytes does not make overdrinking safe.
A sports nutritionist can help plan mineral intake for your exercise demands.
Mineral and electrolyte imbalances
The phrase alone can sound worrying. Athletes know this is something to take seriously.
Causes
Exercise can cause substantial sweating and mineral loss as well as water loss. Replace appropriate amounts through food and fluids. Drinking excessive amounts can lower the mineral concentration in the blood; the aim is to match your needs, rather than force fluids.
Possible problems
An electrolyte imbalance may contribute to muscle cramps, requiring a pause and rest. A temporary drop in sporting performance is preferable to pushing through and risking injury.
Severe hyponatraemia can cause dizziness, fainting and even death. Pay attention to how you feel and, for very demanding exercise, develop a nutrition and hydration plan appropriate to your losses.
Can foods prevent cramps?
There is no magic food, but nutrition can help address some contributing factors. Your plan should provide enough energy, be rich in vitamins and minerals and support appropriate hydration.
For ideas, explore our high-protein vegetarian menu, which also provides plenty of micronutrients.
A varied, balanced diet is the best starting point for getting the macronutrients and micronutrients your body needs to perform at 100%.
Useful foods include:
- Bananas and other fruit, or avocado, which supply potassium for normal muscle function and contraction.
- Complex carbohydrates such as potatoes, which can also provide sodium when cooked with a little salt.
- Pulses, seeds, leafy green vegetables and wholegrains, which supply magnesium to support nervous system function.
Putting it together
Understanding cramps helps, but working with a nutritionist who can plan your diet in detail gives you personalised support to fuel your body and perform at 100%.
If you do intense training and worry about meeting mineral needs, explore our Amapro subscription. Your sports nutritionist will plan meals, exercise fuelling and supplementation around your activity.
