Winter sports injuries are 30% higher than in other seasons. Experts remind the public to ensure safety during exercise and not to make good wishes against sports injuries .
â– dying
Sudden cardiac death includes both quiet and exercise types, of which 81% of sudden deaths are quiet, due to sudden coronary heart disease and pulmonary embolism. In addition to sudden death from heart disease, excessive exercise is also an important cause of sudden death. If the heart circulation system is overwhelmed during long-distance running, the amount of blood and oxygen required will suddenly increase, but the supply will be relatively reduced. In this state of blood and oxygen supply, the heart of the runner will experience acute ischemia. Then, cardiac arrest and interruption of cerebral blood flow occur. When running, you must ensure the safety of your exercise. If you feel uncomfortable while running, stop immediately and don't hold it hard.
â– tennis elbow
Not only tennis can cause "tennis elbow", but also badminton, table tennis and housework can cause illness. The patient will feel pain on the outside of the elbow, the hand grip strength is reduced and the force is poor. It is very difficult to play the backhand ball, mainly due to inflammation of the muscle tendon. Acute pain after exercise should be applied to ice, oral and topical anti-inflammatory painkillers. Chronic inflammation can be used for physical therapy and elbow pads.
â– Peri-shoulder tendon strain
The main reason for the injury is repeated repeated overloading, which causes the tendons and muscles of the shoulder to be repeatedly stimulated and damaged. The affected area will be inflamed and swollen, and the activity will be intensified. Periarticular tendon damage can be divided into acute injury , chronic strain and tendon tear. The typical condition is that the shoulder muscles are swollen and painful after playing the ball, and it is painful or even difficult to raise the arm slowly. For example, the tendon tear will feel weak and weak. In the acute phase after injury, ice should be applied, and the shoulder joint should rest more and reduce the amount of activity. Repeated illnesses and serious injuries require medical attention.
â– Knee ligament, meniscus injury
Knee ligaments are important for stabilizing joints. Sprains and collisions during exercise can cause ligament tears, joint instability, swelling and pain after activity. The meniscus is the two cartilage pads in the knee joint and is the shock absorber of the human body. After the meniscus injury, tears can occur in the joints, and pain in deep squats. If the knee ligament and meniscus injury are not found in time, it is easy to be repeatedly injured when continuing to move, causing traumatic synovitis and articular cartilage wear, leading to early joint deterioration.
â– Fracture
There are two common types of fractures. One is that there is no wound, the flesh is not broken, and it is called a closed fracture. The other is that the tip of the bone penetrates the flesh and is called an open fracture. For open fractures, you can not return, massage or massage by hand, otherwise it may cause osteomyelitis. Apply disinfectant gauze to the affected area. After hemostasis, fix it with flat wood board and send it to hospital for treatment. If the fracture is in the upper limb, the joint can be fixed on the trunk; if the fracture is in the lower limb, the leg can be straightened, fixed on the contralateral limb and sent to the hospital for treatment.
■Muscle 痉挛
Cramps are caused by excessive contraction caused by cold stimulation, excessive mental stress, and excessive physical exertion. They are most common in some long-term sports or swimming. It is prone to cramps when warm-up exercises are not fully prepared. When cramps occur, the muscles are hard and painful, and often cannot be relieved immediately. If it is not treated properly, it will cause muscle damage.
â– Muscle damage
In addition to muscle contusion caused by direct external force, muscle damage is mainly caused by indirect external force. After a muscle strain, the wound is painful, swollen, tender, or cramped, and the touch is hard. Pain is aggravated when the injured muscle is actively contracting or passively elongating.
â– Abdominal tingling
Lateral abdominal pain mainly occurs when people stop exercising for a period of time, restart the beginning of exercise training, or occasionally participate in physical activity. It is generally believed that flank pain is caused by hypoxic pain caused by insufficient blood flow in the respiratory muscles during exercise. Severe exercise immediately after a meal or gas accumulation in the intestine may also cause flank pain.
