What is freediving?
Freediving, also called breathing tribute or apnea diving, sinks without the use of the respiratory apparatus. Freediving is a sport with several different categories of competition, such as diving with fins or without sailing, weight loop, deep records set in the ocean and breathing records set in swimming pools. There are competitions of men and women in professional liberation. While human brain cells do not tolerate the period of apnea for more than five minutes and can be damaged after only three minutes, understanding the body reflexes in combination with training allows world -class professionals to detain nine to nine minutes. This is mainly because it takes advantage of the diving reflex .
Diving Reflex is a key factor in any freediving sport. When a person is immersed in water, some processes naturally take over. The heart rate begins to slow down. With practice, it can only beat four times a minute. Blood vessels are limited in the limbs andIt forces blood into vital organs of the body. At the same time, the blood vessels in the lungs are filled with plasma, which reduces the volume to prevent their collapse.
When the heart rhythm slows down, the body saves energy. The air trapped in the lungs continues to oxygenate the blood. This extends the time when the body can safely go without breathing. However, because there is no breathing, carbon dioxide (CO2) creates in the bloodstream and muscles. Setting CO2 is a limiting factor in freediving. When the body is saturated with CO2, it burns a huge reflective response to breathing.
Unintentional freedoms sometimes hyperviantilated before freediving, they believe it saturates blood with oxygen, which allows longer divis. In fact, it does not increase oxygen, but removes CO2 from the blood, simply delaying the reflexive need to breathe. This is extremely dangerous and even threatening life because the body may occur before the diver feels the need to breathe. When this happens, the diver can underwater black. Shallow Water Blackout is considered to be responsible for many utilized accidents.
Freediving is an exciting but potentially dangerous sport that can lead to serious injury or death. Pressures on the body in Freediving Deepwater can reach £ 235 per square inch (16.5 kilograms per square centimeter). Although freediving has roots that reach back for 4,000 years, when people often dive behind pearls and food, today's enthusiasts are encouraged to take professional courses to learn how to use this extreme sport safely. For those who first monitor security, freediving can be a beautiful way to experience the ever -exoxotic underwater world.
