Adrenaline: whether to raise the car yourself?
In 2006, in Tucson, Ariz., named Tim Boyle saw the Chevrolet Camaro knocked 18-year-old Kyle Holtrasta. Vehicle crushed teenager who was still alive at the bottom. Boyle ran to the scene of the accident, raised Camaro, and the driver of the car pulled a guy in a safe place.
In 1982, in Lawrenceville, Ga., Angela Cavallo lifted Chevrolet Impala, which fell to her son Tony, torn from the mounts, which was strengthened in the course of repair. Mrs. Cavallo lifted the car high enough and held long enough for two neighbors replaced fixtures and Tony dragged under the car.
Marie “Bootsie” Python sheared your lawn in High Island, Texas, when the mower suddenly jumped up. Python young granddaughter, Evie, tried to stop the mower, but was hit by the car still running. Python caught lawnmower and easily threw it from his granddaughter, who escaped with four fingers cut off. Later Python again tried to raise the car, but it turned out that this is impossible.
I’m sure you have also heard about such. What explains these superhuman feats of strength? Maybe we sleep superheroes? Or amazing power? Maybe we and lifting machines do not need?
As documented such instances of hysterical and unnatural forces occur only in stressful situations. Medicine does not recognize them. This is largely due to the problem of gathering evidence. Cases like these have occurred spontaneously and play these situations in the clinical setting would be unethical and dangerous.
Nevertheless, we know that behind all this adrenaline – a hormone that can increase the power at times for short periods of time.
Woman against white bear
Adrenaline not only helps people to pick up the car. In Ivudzhivike, state of Quebec in 2006, Lydia Anjou overcame a large polar bear, when I saw that he sent to her son and another boy playing hockey. Anjou clung to the polar bear and fought with him, while the boys ran for help. Although Anjou received some wounds, a polar bear lost the fight. Anju competed with him in melee long enough to ensure that the neighbor was able to shoot the bear four times, until he died.
Adrenaline and strength
When we feel fear or face a sudden dangerous situation, the human body undergoes an amazing change. Stress – for example, the spectacle of your son falls on car – stimulates the hypothalamus. This area of the brain responsible for maintaining the balance between stress and relaxation in your body. When there is a danger, it sends a chemical signal to the adrenal gland, activating the sympathetic system, immersing the body in the excited state. The adrenal glands release adrenaline (epinephrine) and noradrenaline (norepinephrine), hormones that create a state of readiness and help a person overcome the danger. Together, these hormones increase the level of heart rate, improve breathing, pupils dilate, slows digestion and – most importantly – allow the muscles to contract.
All these changes in normal physical condition allows us to meet face to face danger. They make us more nimble, can process more information and help us to use more energy. But the effect of adrenaline on the muscle gives amazing power. Adrenaline affects the muscles, allowing them to shrink much more than in a calm body.
When adrenaline is released by the adrenal medulla – the inner region of the adrenal glands, which are located just above the kidneys – blood flows more easily to the muscles. More oxygen reaches the muscles in light of this additional blood and muscles work in hard mode. Skeletal muscles that attach to bones via tendons, activated by electrical impulses of the nervous system. When they are stimulated, the muscles contract, that is getting shorter and shrink. This happens when you pick up objects, run or beat. Epinephrine also facilitates the conversion of the fuel supply body (glycogen) in its fuel (glucose). This carbohydrate provides energy muscles, and a sudden burst of glucose strengthens the muscles in the future.
So, we have superhuman strength, which is released when we are faced with danger? You could say that.
Some suggest that we typically use only a small percentage of the capabilities of our muscles. When we are faced with danger, we overcome the limitation of our body and just act. Adrenaline, causing a dramatic increase in strength, enables a person to pick up the car. In other words, when faced with a state of extreme stress (some “borderline situation,” according to Jaspers), we can not help liberate our muscles from constraints under which they work every day.
This theory, by the way, confirmed that happens to a man when he has an electric shock. After hitting a person can throw a substantial distance. But it is not associated with an electric shock. On the contrary, it is the result of a sudden strong muscle contractions rights because the electric charge passed through the body. Another confirmation of building muscles. People do not jump across the room and Aki Wolverines can not lift the machine without using the resources in a non-threat.
But why do not we get a permanent superhuman strength? Would not it be useful?
Easy does it – will continue
Why do not we live in a state of constant turmoil? Why can we be people of steel only for short bursts? The answer is simple: otherwise it will kill us.
Potential treatment of muscle strength in the real muscle strength should occur as a result of training. Muscles become stronger with the passage of time during heavy lifting. While our muscles are able to deliver a force that may seem supernatural, during a collision with danger, the consequences are no less dangerous than the situation itself. Muscles that are beyond their own capabilities, can break, joints can get out of their sockets.
Austrian physician Hans Selye studied the human response to stress and concluded that there are three stages, which he defined as the general adaptation syndrome. The first stage occurs when you are confronted with stress, stage of the reaction to the alarm (RT). This stage involves the activation reaction “flee or fight” response to stress. All internal alarm bells start to work and willingness to activate or stay away. The next stage – a stage of resistance (SR). Under resistance human response to danger maximum: pupils dilate, heart ready to jump out of my chest, breathing active, and the muscles contract. At this point, you run for survival, pick up the car to make the other person, or reside in another situation “above average”.
At the moment, when you see how man crushed car, stress acts long. The body begins to relax and return to normal operation after a few tense minutes. Once the stress passes, the parasympathetic system is activated. This system plays opposite sympathetic role. When the case turns on the parasympathetic system, heart rate slows, breathing returns to normal, the muscles relax and nonessential functions (like digestion) will work again. Hypothalamus, which is responsible for the launch as a sympathetic reaction in case of danger, and the parasympathetic response to what the danger goes, takes support balance. This balance, the normal state of the body is called homeostasis.
When the body is in an excited state for a long period, it gets to the final state of the general adaptation syndrome – a state of exhaustion (SI). This stage occurs when the response to stress continues for too long. In this state of hyperarousal body’s immune system begins to wear and to unravel. Person becomes more susceptible to infections and other diseases, as defenses have been spent to fight the danger. In a state of prolonged stress can easily catch a cold or have a heart attack. State of exhaustion clearly visible in cases of long-term stress, such as in the workplace.
Summarizing, we can say a big thank you to the homeostasis of our bodies. If we were constantly in the excited state, we would run out of fuel. And while we are trying by all means to stop aging .
