Study : Adrenaline Rush and Super Strenght

When we feel fear or are faced with a sudden dangerous situation, the human body undergoes an amazing change.This change in our normal physical state prepare us to face danger head-on. It makes us more agile, allow us to take in more information and help us use more energy. But adrenaline's effect on muscles accounts for amazing strength. Adrenaline acts on muscles, allowing them to contract more than they can when the body is in a calm or neutral state.

Some theorize that we normally use only a small percentage of our muscles' capabilities. When we are confronted with danger, we transcend the limitations of our muscles and simply act. The rush of adrenaline, which accounts for a sudden increase in strength, helps to facilitate a person lifting a car. In other words, when confronted with extreme stress, we involuntarily use our muscles beyond the limitations of their normal voluntary use.Also,our fear seems to decrease,and tend to react to the potential danger without taking in consideration the consequences.

This theory is supported by what happens when a person is electrocuted. Someone who is shocked can be thrown a notable distance from where the shock took place. But this is not due to the electric shock. Instead, it's a sudden and violent contraction of the person's muscles as a result of the electrical charge flowing through the body. This demonstrates a potential for muscle contraction that isn't utilized under normal circumstances. In much the same way that people can't throw themselves across the room, they also can't normally lift a car - the resources aren't available without the threat.

But why we can't use this "power" all the time?The answer is simple : when the body stays in an excited state for a prolonged period, it enters the final state of Selye's general adaptation syndrome - the state of exhaustion (SE).If we existed in an excited state all the time, we would run out of gas (a person in a prolonged state of stress may easily get ill or have an increased chance of suffering a heart attack).
