When a person feels scared or faced with a dangerous situation , then the human body will experience tremendous changes . Suddenly, the body becomes stronger as the mighty Samson
legend . Apparently there is a hormone that triggers the body suddenly becomes a powerful figure like Samson. So do not be surprised if suddenly in an emergency people can lift heavy stuff that if in normal conditions is not possible. The secret is in the body namely 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 dangerous situations 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 a chemical signal to the adrenal gland to activate the sympathetic system. This gland will then issue adrenaline and noradrenaline. As quoted from HowStuffWorks, these hormones together can increase heart rate, rapid breathing, dilated pupils, slow down digestion and allows the muscles to contract more than usual. The release of this hormone makes the body better prepared to face danger, thus making a person become more agile, more information and help a person uses more energy. The effects of adrenaline increase the amount of muscle mass and incredible strength. Adrenaline also allows muscles to work more strongly than when the body is in neutral or calm. When 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. Frame muscles attached to bones will be activated by electrical stimulation of the nervous system. When stimulated, the muscles will contract, which means the muscles shorten and tighten. This is what makes a person could lift a large item or throwing a punch. Adrenaline also facilitate the change of glycogen into glucose, which means providing additional energy for muscles. This of course can strengthen the muscles that already exist. 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 his ability.
