why do we get cramp when we over exercise?

Answer 1

A muscle cramp is a painful spasm of your muscle. It's caused by a prolonged tightening of that muscle, leading to it being shortened. The spasm can last from a few seconds to 15 minutes.

You do not have any control of this spasm and the muscle often feels hard and painful. Muscle cramps, especially in the legs, are very common. The small muscles of the feet are also sometimes affected. The muscle may remain tender for up to 24 hours after a leg cramp.

Cramp often occurs as a result of using your muscles a lot. It is common in athletes, especially long distance runners, and tennis and football players.

Cramp often happens after you have sweated a lot. Sweat is high in sodium and loss of sodium upsets the way your muscle works.

It can also occur with repetitive movements, such as writing (writer's cramp). It can also happen when you lie in an awkward position (night cramp). Night cramps may wake you from sleep.

You can relieve the pain of muscle cramp by stretching and gently massaging the muscle. Grasp your muscle with one hand and pull back on your toes with the other to point the toes upwards. This helps to relieve the spasm.

Regular calf stretching exercises will often prevent leg cramps. See your GP if you frequently get painful night cramps as quinine tablets may help.

Drink plenty of fluid before, during and after exercising or playing sport, and make sure you warm up properly before you begin.

Answer 2

It can happen for a number of reasons: dehydration, a drop in potassium levels, a build up of lactic acid, spasmodic contractions of the muscle fibres, etc. Try drinking sports drinks when excercising it has all the right electrolytes and things needed to replace what you lose through perspiration caused by excercise. You can also try whey protein it helps in repairing and rebuilding muscles. I have it before gym and find im not as sore the day after as I am if I dont have it.

Answer 3

Cramps are continuous muscle contraction due to...

1 - Depleted Electrolytes
2 - A pair of muscles/fibers being interrupted

Chronic forms of cramps are caused by Nerve Irritation

Answer 4

There are five basic causes of cramping: hyperflexion; inadequate oxygenation; exposure to large changes in temperature; dehydration; or low blood salt.

Electrolyte disturbance may cause cramping and tetany of muscles, particularly hypokalemia (a low level of potassium) and hypocalcemia (a low level of calcium). This disturbance arises as the body loses large amounts of interstitial fluid through sweat. This interstitial fluid is composed mostly of water and table salt (NaCl). The loss of osmotically active particles outside muscle cells(NaCl) leads to a disturbance of the osmotic balance and swelling of muscle cells as these contain more osmotically active particles. This causes the calcium pump between the muscle lumen and sarcoplasmic reticulum to short circuit and the calcium ions remain bound to the tropomyosin and the muscle contraction is continued.

Answer 5

Not postitive, but it could just be the bodies response to getting tired. If it is having trouble getting oxygen or something there has to be a reaction. Why do we feel pain, it's the bodies reaction to something harmful to it. Maybe cramps are just a sign of when we are getting tired or overworked or not working properly. That or it could have something to do with things on the molecular level such as the production of ATP

Answer 6

if you are talking about when you are in the middle of doing an exercise the answer is lacid acid. if you are talking about afterward, than that could be complicated. could be lack of calcium, dehydration, or other things. sometime if you over do it then they will cramp later. stretching good after wards can help with this

Answer 7

We get cramps when we over exercise because your body is trying to make blood unoxidated or without oxogen. When your body does this, it produces an acid that builds up causing pain.

Answer 8

Cramps are caused by a build up of lactic acid in the muscle tissue.

Answer 9

the answer is fermentation when we exerscise sometimes we dont get enough oxygen, so fermentation is the process of releasing energy which some times cause cramps

Answer 10

cramps occur because of low calcium or potassium in the blood, dehydration, or poor circulation
