Physiologically speaking, warm-up exercise can increase the strength of muscle contraction; improve muscle coordination; prevent or reduce muscle, tendon, ligament injuries; enhance the ability of hemoglobin and muscle protein binding and release oxygen; improve metabolic processes; reduce blood vessels Wall resistance. Appropriate elevation of body temperature can provide sufficient improvement in the sensitivity of nerve receptors and nerve conduction velocity.
At the same time, it can also stimulate vasodilation and increase blood flow at the active site. The flow rate and flow rate of blood increase as the muscle temperature rises. The supply of energy and the elimination of metabolites have improved. Due to the above effects resulting from warm-up exercises, the range of motion of various joints of the human body has been increased, and the coordination during exercise has been enhanced. The muscle's stretching ability achieves the best effect. To the greatest extent possible to avoid the athletes in the snow and ice in the incidence of injury.

At this time, in addition to skin swelling, blisters of different sizes also appeared. After the blisters broke, yellow liquid was discharged. The patient felt conscious of fever and severe pain. The third degree is necrosis. Partial skin or limb necrosis, the skin is purple brown, the local feeling disappeared. In winter sports, frostbite is more common in the end of the hand, foot, nose, ears and genitals. The first degree of frostbite more, the third degree less frostbite.
