Cramp is another common injury for athletes at all levels and affects hard working muscles such as the calves in runners and the arm in tennis players.
But despite being able to cure all kinds of killer diseases, scientists still don't know what causes it!
WHAT IS CRAMP?
It is when a muscle goes into spasm and refuses to relax.
The pain in the affected muscle can range from a slight spasm to agonising pain. It can last a few seconds through to 15 minutes and can recur.
WHY DO WE GET CRAMP?
There are three major factors:
Fatigue: Cramp sets in when our muscles are tired
Hydration: We get cramp when we have not drunk enough water
Conditioning: The less fit we are, the more likely we are to suffer from cramp
Scientists are unsure how much influence each of these areas have on cramp.
WHO DOES IT AFFECT?
Cramp is common in most athletes, especially long distance runners and tennis and football players.
HOW DOES IT HAPPEN?
It can set in during long bouts of exercise, particularly when the weather is hot and a player is dehydrating.
The immediate treatment for muscle cramp is to stretch and gently massage the muscle. Use ice packs for severe cases and drink water or a sports drink.
Grasp the muscle with one hand and pull back on the toes with the other. Point toes upward to help relieve the spasm.
You can continue exercising after massage but if the pain is too acute then 24 hours rest is advised.
HOW CAN YOU AVOID CRAMP?
A proper warm-up (especially stretching) is essential, good fitness, plenty of fluid and a nutritious diet.
