My articles | When a person feels scared or confronted with a dangerous situation, then the body will experience tremendous changes. Suddenly become a powerful body like the legend of the mighty Samson.
Apparently there is a hormone that triggers the body suddenly becomes a powerful figure like Samson. So do not be surprised if all of a sudden in an emergency people can lift heavy items when in normal conditions is not possible.
The secret is in the body of the cooperation of two hormones adrenaline (epinephrine) and noradrenaline (norepinephrine), the hormone that creates a state of readiness in order to help the man to face danger.
So when a person feels scared or confronted with a dangerous situation the body will stimulate the hypothalamus, the area of the brain responsible for maintaining the balance between stress and relaxation in the body.
When there is a warning of danger, the body will send chemical signals to the adrenal glands to activate the sympathetic system. This gland will then issue adrenalin and noradrenalin.
As quoted from HowStuffWorks, Monday (07/05/2010) these hormones together can increase the heart rate, rapid breathing, dilated pupils, slow digestion and allow the muscles to contract more than usual.
The release of these hormones make the body more ready to face danger, so that makes a person become more nimble, more information and help people use more energy.
The effects of adrenaline increase the amount of muscle mass and incredible strength.Adrenalin also allows muscles to work more strongly than when the body is in neutral or calm.
When the adrenaline is released by the adrenal medulla, the blood becomes more easily flow to the muscles, which means more oxygen is carried to the muscles so the muscles can work at higher levels.
Framework of the muscles attached to bones will be activated by electrical stimulation of the nervous system. When stimulated, which means the muscles will contract and tighten the muscles shorten. This is what makes a person can lift a large item or throw a punch.
Adrenalin also facilitate the change of glycogen into glucose, which means providing additional energy for muscles. This of course can reinforce existing muscles.
Some theories suggest using only a fraction of human muscle power. But when faced with danger, a person can act with a force that transcends the limitations of the muscle.
