Soft tissue injury is the most common form of trauma in athletics. It involves damage to muscles， tendons， ligaments， and even nerves and blood vessels. Common soft tissue injuries include bruises， punctures， bruises， and strains and strains.

1. the cause of soft tissue injury

In track and field sports， there are many causes of soft tissue injury. To sum up， there are mainly the following aspects. The first is that the preparations are insufficient. Intensified track and field sports and high load on muscle ligaments， if athletes pay too little attention to preparation activities， especially the whole bodys intramuscular stretching activities， and joints， ligaments， and muscles are not fully active， they are eager to participate in competitions and training. It is easy to cause muscle and ligament strain injuries. Second， the training course is not reasonable. Continuously arrange many large-volume exercises without proper adjustments. Arrangements for training and arranging training are not in the right order. Exercises with great intensity are placed in the latter part of the training session. The body is consumed more， in a state of fatigue， and energy is not concentrated ， it is easy to hurt； third is poor flexibility training.

Flexibility is an important quality exercise. In the basic training， if you ignore the practice of stretching muscles， and do not pay attention to the arrangement of relaxation exercises， in the long term， it will make the muscles stiff， the elasticity will drop， and it will easily lead to tearing； Fourth， the local exercise load is too heavy. When arranging the amount of exercise， the physical characteristics of the athlete are not fully taken into account. The amount of exercise exceeds the physiological burden that the athlete may bear. In particular， the local burden is too large and is the main cause of injuries in training. Fifth， the development of muscle power is unbalanced. These methods have a deeper stimulation of the thigh muscle strength and active contraction muscles.There is little or no emphasis on the strength of the waist and abdomen and the power of the passive contraction muscles， which creates an imbalance in muscle strength and can also cause injuries. In addition， many injuries were caused by carelessness of athletes. We often see some athletes being placed on the track side of the equipment or other items to stumble or twist the ankle， or be swollen and bruised.

2. emergency treatment of soft tissue injury

Successfully returning an injured athlete to the game often depends on the first person to diagnose the injury and take the right first aid. When the athlete is injured， the coach must make a diagnosis and decide whether to let the injured athlete continue to participate in the competition or training.

（1） first aid treatment of lighter soft tissue injuries

There are two main types of processing methods.One is cold treatment： place ice cubes or ice packs directly or indirectly on the skin of the injured area. Note： Ice cubes can cause frostbite if they come in contact with the skin for too long. The use of repetitive 5 to 10 minute cold treatment is better than a longer one time cold treatment.The second is pressure dressing： Wrap wound bandages or press the injured area directly with hands. But pay attention to the pressure bandage can not be wrapped too tight， which will hinder the blood circulation of the injured area.

（2）First aid treatment for more serious soft tissue injuries

Moderate and severe injuries， athletes will have obvious pain. In case of a strain， athletes usually feel “pulled” when they are injured. In moderate injuries， athletes can still complete their actions. However， when a serious injury occurs， the athlete will be stopped to exercise because of severe pain and weakness. The lacerations are generally caused by fierce contraction against strong resistance. This type of injury is more often seen in adolescents. For severe soft tissue injury， cold treatment should be taken immediately after injury， and the limb should be pressurized and raised up to 48 hours after injury. Further treatment should be performed according to the injury. Such as： external application of new wounds， the pain is heavier orally taking beaten pills， Qiju San and so on. After 48 hours， bleeding stopped and acute inflammation gradually subsided， but the affected area still suffered from blood stasis and swelling. Treatment should mainly improve the blood and lymphatic circulation of the wound， promote tissue metabolism， promote the absorption of congestion and exudation， and accelerate regeneration.
