1, how to deal with exercise syncope?

Conscious people-lie down and rest, head slightly lower, feet raised, loosen the collar, pay attention to keep warm; Push and knead again from calf to thigh and knead the whole body to make blood flow back; After some remission, you can add the right amount of water and sugar to recover.

2. What is exercise syncope?

Sports syncope refers to the sudden and short-term loss of consciousness, disappearance of muscle tension and fall caused by transient blood supply deficiency or changes in blood chemicals during or after exercise.

3. Common types of exercise syncope

Hypoglycemic syncope is a common exercise syncope, which is more common in long-distance sports events. People with a history of hypoglycemia are prone to induce hypoglycemia during exercise. Precursor symptoms include hunger, weakness, sweating, dizziness, tachycardia, trance and so on. After glucose supplementation, you can quickly regain consciousness.

Cardiogenic syncope is caused by various heart diseases (such as hypertrophic cardiomyopathy, coronary artery malformation, coronary heart disease, myocarditis, valvular heart disease, Marfan syndrome, sinus node artery stenosis, preexcitation syndrome, long QT syndrome, arrhythmogenic right ventricular cardiomyopathy, etc.). ) is a dangerous but common type of syncope, which is common in football, basketball and cycling.

Heatstroke faints, and the body produces more heat during exercise. However, due to the high temperature of the external environment, the body's temperature regulation ability decreases, which leads to the increase of body temperature and the dysfunction of multiple organs, especially the central nervous system. In addition, excessive sweating and dehydration, imbalance of water and electrolyte in the body and reduction of blood volume can also lead to syncope. The disease mostly occurs in high temperature and high humidity environment, especially in long-distance running, marathon, cross-country running, cycling, football and other projects. Athletes are prone to dizziness, headache, chest tightness, thirst, nausea, vomiting, tachycardia, muscle spasm and other symptoms in summer training and competition. At this time, if no cooling measures are taken, syncope or even death may occur.

How to prevent exercise syncope?

1, adhere to the principle of scientific and systematic training to avoid excessive fatigue and tension.

2. People who take part in strenuous exercise for a long time must be well-trained athletes.

3, illness recovery and the elderly to participate in sports must be carried out according to the exercise prescription.

10, in addition to team doctors, athletes and coaches should have the ability to prevent and simply deal with syncope during sports.

Manifestations of exercise syncope

During or after exercise, sudden and short-term loss of consciousness (LOC) and loss of muscle tension accompanied by falls caused by short-term blood supply to the brain or chemicals in the blood are called sports vertigo. There are mainly the following performances:

Gravity shock syncope

When athletes perform the following lower limb orienteering, the oxygen consumption of lower limb muscles increases and blood vessels dilate. If the soil stops after strenuous exercise, a large amount of blood will accumulate in the blood of the lower limbs, resulting in insufficient blood supply to the brain. This situation is more common in track and field events: symptoms include dizziness, weakness, nausea, pallor, chills in the limbs, and severe cases can faint.

Residents' hypotensive syncope

When the horizontal position suddenly becomes an upright position. Muscle pump function and vascular regulation function can make blood accumulate in lower limbs, resulting in transient cerebral ischemia, which mostly occurs after swimming competition. Sudden atresia without prodromal symptoms

Paroxysmal myasthenia gravis

Also known as sudden weakness, it refers to sudden collapse caused by the decrease of the response threshold of the central nervous system and the temporary damage of salty limbs to gravity. More common in rowing competitions. The athlete left to finish the game. (After 0 minutes, he fell down. Then I fainted. The duration of syncope is very short, only a few seconds.
