Is there a specific cause for cramps?

Aug 25, 2025

Why do cramps actually occur? Is it because the muscles are tired, because we lack salt and electrolytes – or is it just the body playing tricks on us? Many have experienced standing in the middle of a race or a hard workout, when their leg suddenly locks up

There are many explanations – everything from dehydration and mineral deficiencies to a lack of warm-up. But the truth is that none of these explanations can be the whole story. Cramps affect both beginners and experienced athletes, and they can occur in cold, hot and under a wide range of conditions.

What does the research say?
Several studies have attempted to find the exact cause, but there is still no clear conclusion. Cramps appear to be multifactorial. It may be a combination of muscle fatigue, imbalances in electrolytes such as sodium, potassium and magnesium, dehydration, nervous system signals – or even a genetic predisposition.

Cramps are a much discussed and researched area, but no concrete answer has yet been found, no conclusion on the exact reasons why cramps occur.

Although there is no one “secret” behind cramps, you can reduce the risk and try to prevent cramps as best as possible.

Always make sure you are well hydrated - get enough electrolytes and fluids during longer workouts

Drink Premium Endurance before and during long workouts

Always make sure to keep track of your energy intake during longer training sessions or when it is high intensity.

If necessary, consume a Fuel Bar C35 beforehand, and keep an Energy Gel C30 in your pocket.

Focus on strength and mobility so that the muscles are better equipped for the load

Conclusion
There's no single answer to why cramps happen—and that's what makes them so fascinating. We just did a podcast on the subject, delving into the myths, research, and athlete experiences. Because while cramps are still a mystery, with the right habits, you can be better prepared the next time they come knocking, and maybe even avoid them altogether.
