Start by understanding the basic mechanisms of the body during exercise. When starting to exercise or play sports, muscles in various parts of the body require more energy. The oxygen level in the peripheral blood vessels will decrease, stimulating the sympathetic nervous system to work more, resulting in a physiological response of the heart and blood vessels to increase the volume of blood that is contract by the heart per unit of time.
This value is an important factor that determines the maximum potential of the body to burn oxygen in each person. The normal value of the volume of blood contracted by the heart per unit of time while resting is approximately 5 liters per minute, but it can increase up to 20-40 liters per minute during exercise in normal people or 50-60 liters per minute in professional or competitive athletes.
Syncope is often cause by insufficient blood and oxygen supply to the brain for a short period of time. Symptoms include nausea, สมัคร ufabet, dizziness, sudden changes in body temperature, abnormal vision, or seeing images in black and white before the blackout occurs.
What causes fainting?
Chronic diseases are another factor that causes fainting while exercising, such as high blood pressure, heart disease, diabetes, anemia, obesity, epilepsy, etc. For people who have chronic diseases or may not have known before that they have these diseases, in fact, you can still exercise, but not too hard.
Air Air pollution, whether it is dust, toxic fumes, toxins, can harm people who exercise. If the amount is high enough, it can make you feel nauseous, dizzy, dizzy and eventually faint. Also, if you exercise in very cold or hot air. It will cause the body temperature to change suddenly, causing fainting as well. Or it may be more serious, leading to death. Therefore, you should exercise in a place with a normal and constant temperature.
Age is the most important factor that causes fainting without realizing it. All organs will be fully develop by the age of 30, but after that, they will gradually deteriorate. As we age, blood vessels will narrow, and the blood supply to the heart muscle will decrease. Therefore, if we increase in age but still exercise as hard as before, we will experience fainting while exercising. And if it is severe, it may even be fatal. Therefore, the elderly must exercise in moderation and not overdo it.
Fainting can have many causes, so if you have any of the risk factors mention above. You should find a way to rest or relax while exercising to avoid a potentially dangerous fainting spell.
