What causes leg cramps after exercise

Excessive exercise often causes "leg cramps", especially in the calves and soles of the feet. "Leg cramps" are long-term involuntary contraction of muscles. There are many reasons for "leg cramps":

1. Because there is no sufficient preparation for activities before excessive exercise, the muscles suddenly switch from a static state to an activated state, and the muscles of the feet cannot be integrated all at once. , muscle atrophy ("leg cramps") occurs;

2. A significant reduction in external temperature can also cause "leg cramps". For example, if you suddenly catch a cold, the muscles will have obvious muscle atrophy reaction. Therefore, when exercising and swimming in winter, "leg cramps" sometimes occur in the calves and soles of the feet. It is especially common when swimming, because when a person enters the water, the body dissipates 25 times more heat than in the air, irritating the nerve effectors on the skin, so according to the nerve center The system will cause muscle atrophy;

3. When you are overworked during exercise, the function of the central nervous system that controls the muscles changes, and some metabolic substances (such as lactobacilli, etc.) accumulate in the muscles, causing the muscles to Changes in the function of tissues are also the cause of "leg cramps";

4. Excessive exercise for a long time, sweating a lot, taking away salt, and lack of fluoride (mainly salt) in the body, also Can cause "leg cramps".

Now that we know the main causes of "leg cramps", when participating in sports competitions, if we can pay attention to the following content, we can avoid leg cramps:

After reading the above introduction, we can understand that there are various reasons for leg cramps. Most of them are closely related to lack of preparation before exercise, and excessive exercise for a long time. It may also cause leg cramps, so when this happens, you must pay attention not to overexert yourself during exercise and make adequate preparations. What causes leg cramps during exercise?

(1) The body loses too much salt.

During excessive exercise, the body sweats too much, which causes the body to lose too much salt, destroying the body's electrolytic balance. Because the body's sodium oxide content is too low, the body's fluid regulation of the muscles and nerves is increased. Cause muscle spasms.

(2) Muscle contraction and left ventricular imbalance.

During exercise, due to the rapid and continuous contraction of muscles, the time for relaxation is too short, which destroys the coordinated relationship between muscle contraction and left ventricular replacement development, causing muscle spasm. This kind of obvious contraction and suppression of left ventricular spasticity is easy to occur when the muscle is strained.

(3) Cold irritation.

When carrying out outdoor activities in a cold environment, if there is no adequate warm-up exercise, muscle cramps often occur when the muscles are stimulated by the cold.

When muscle spasm occurs, part of the muscle becomes hard or bulging, causing severe pain that is not easily relieved for a while. After some symptoms are relieved, there is still discomfort and spasticity may occur again. When muscle spasm occurs, generally by gradually increasing force and continuing to stretch, the spastic muscles can be released and the pain relieved. When calf cramps occur, you can lie flat on the ground, hold the forefoot with the opposite hand, straighten the kneecap and pull hard; you can also sit or lie on your back, straighten the kneecap, and hold the foot against the abdomen with both hands of a partner to relieve cramps. The patient can stretch his body forward with appropriate force, and his partner can force his feet to slowly extend his back. At the same time, pushing, kneading, and pinching the leg muscles can relieve the spasm.

In addition to paying attention to adding a certain amount of salt to prevent foot cramps during exercise, you also need to keep warm. Especially when the temperature outside is cooler, be sure to wear fashionable and sporty jeans and clothes. Naked. In this way, it can have a good cold-proof and warm-keeping effect, and of course it will reduce the possibility of leg cramps. Sufficient warm-up exercises before exercise can also prevent leg cramps.
