How to prevent sports injuries?

Everyone hopes to have a healthy body, but in order to make the body healthier, many people always do physical exercise. However, if they do not master the way of exercise, they are prone to injuries. This not only fails to play a fitness role but also easily causes harm to the body. Therefore, we must do a good job of prevention in our daily life. Let’s learn about how to prevent sports injuries.

How to prevent sports injuries?

Vigorous exercise often causes cramps, especially in the calves and soles of the feet. A cramp is an involuntary, prolonged muscle contraction. There are several reasons for cramps:

1. Because there is no warm-up before strenuous exercise, the muscles suddenly switch from a static state to an active state, and the leg muscles cannot adapt all at once, resulting in contracture ("cramps");

2. A sudden drop in outside temperature can also cause cramps. For example, if you are suddenly exposed to cold, your muscles will have a strong contraction reaction, so when you exercise or swim in winter, your calves and feet sometimes experience "cramps". It is more common when swimming, because when people enter the water, the heat released by the human body is 25 times greater than in the air, which stimulates the nerve receptors on the skin, thus causing muscle contraction through the central nervous system;

3. When you are overly tired after taking part in strenuous exercise, the function of the nervous system that controls the muscles changes, and some metabolic products (such as lactic acid, etc.) accumulate in the muscles, which changes the function of the muscle tissue and is also the cause of "cramps";

4. Participating in strenuous exercise for a long time and sweating a lot will take away salt, and the lack of chloride (mainly table salt) in the body can also cause "cramps".

Now that we know the main cause of "cramps", we can prevent cramps by paying attention to the following points when doing sports: 1. Be careful to avoid excessive or prolonged cooling of the legs, especially do not stay in the water for too long.

1. Before doing strenuous exercise, you must do enough warm-up activities;

2. Don’t be too tired. You should not swim when you are tired.

3. After sweating a lot, you should supplement some salt appropriately, such as drinking some light salt water, adding a little more salt to the food, etc.

The above is an introduction to how to prevent sports injuries. After understanding it, we know that if we want to better prevent sports injuries, we must warm up well when exercising, and we must not do strenuous exercise at the beginning. There must be a gradual process, and we must pay attention to eating foods high in calcium regularly.
