Causes of syncope after stretching exercise
1. Why do you faint after stretching?
During or after exercise, sudden and short-term loss of consciousness (LOC), disappearance of muscle tension and fall are caused by short-term blood supply to the brain or changes in chemicals in the blood. This situation is called exercise syncope.
Also known as vagal reflex syncope or simple syncope, its incidence accounts for the first place in all kinds of syncope. Factors such as mood fluctuation, mental stimulation or competition pain can induce short-term vasodilation through vagus nerve reflex, which can reduce blood volume and cardiac output, reduce blood pressure and lead to syncope due to insufficient blood supply to the brain. Usually seen in young athletes or inexperienced athletes, especially women.

3. What are the most commonly used stretching exercises after exercise?
3. 1, calf stretching
There is a lot of pressure on the calf during running, so the calf muscles need to be stretched and relaxed after running.
Practice: arms apart, close to the wall. Legs apart, one in front of the other; Bend the front legs, straighten the rear legs, and straighten your feet forward; Put the heel on the ground; Feel the calf muscles stretch and hold for 15-30 seconds; Switch legs.

Matters needing attention in sports stretching
1, first: for stretched muscle groups.
Many people pay attention to bending the body to a greater extent and enhancing flexibility when stretching. The actual correct stretching should only be aimed at the stretched muscle group, which can overcome the resistance of other muscle groups. The less muscle groups you stretch at a time, the better the effect. For example, it is better to stretch both sides of the muscles behind the thigh separately than to stretch both sides at the same time.
2. Second: Keep breathing smoothly.
When stretching, many people habitually hold their breath as soon as they do deep bending. But once you stop breathing, your whole body will hold an abnormal force, and it is difficult for your muscles to fully stretch. Especially before the game, stretching and relaxing is very important. In order to eliminate the tension during stretching, we must pay attention to keeping a deep breath and stretching the muscles carefully.
3. third: stop at a point where you can't feel pain.
Proper stretching will not cause muscle aches the next day. Some people will stretch to the point where they feel intense pain, which is likely to cause injury. For example, it may cause joint torsion, leading to ligament or tendon strain; It may also cause great pressure on the vertebral body; Or twist it to cause damage to other parts of the body.
