Hydration and Electrolyte Replacement
for Muscle Cramps
Adequate hydration and electrolyte balance — particularly sodium, potassium, and magnesium — are the foundation of exercise-associated muscle cramp prevention.
How it works
Dehydration and electrolyte depletion alter muscle membrane excitability and the balance between inhibitory (Golgi tendon organ) and excitatory (muscle spindle) neural signals, predisposing to spontaneous cramping.
What to watch for
Electrolyte replacement (sports drinks, electrolyte tablets) is important during endurance exercise lasting >1 hour. Water alone during prolonged sweating can dilute sodium and worsen cramps (hyponatraemia).
