Tennis injury and protection

In ball games, the intensity of tennis is second only to basketball and football, running more and physical energy consumption. In the 1990s, Prof. Yu Heng of the Institute of Sports Science of the General Administration of Sport of the People’s Republic of China had a total of 107 tennis players (55 male players and 52 female players, with an average age of 18.95 years) on 14 professional teams from the national team and cities and provinces. The two-year epidemiological study of sports injuries concluded that the prevalence of injuries for tennis athletes was 50.47% (including 28.38% for spine injuries, 20.27% for knee joint injuries, and 17.57% for elbow joint injuries).

In tennis enthusiasts, although there are no specific statistics on injuries, in the clinic, injuries to the calf, elbow, and knee are not uncommon.

In the sports injuries of professional players, the most common injuries are muscles, fascia, tendon sheaths and so on, accounting for 56.76% of the total injuries. The causes of injuries are caused by excessive training. Among enthusiasts, many are due to lack of preparation activities, fatigue and other reasons. Therefore, the prevention of sports injuries is an important part of continuing this exercise and improving the level of exercise. Two more data were surprising. Acute injuries in professional athletes accounted for only 14.86%, while chronic injuries and acute to chronic injuries accounted for 85.14%.

Treatment of acute injuries

The purpose of treatment is mainly to stop bleeding, relieve pain, detumescence, control inflammatory response, restore range of normal joint activity, exercise flexibility, muscle strength, endurance, balance and coordination, and ultimately maximize its recovery and painlessly Conduct all activities. However, in the treatment, we must pay attention to the time limit of acute injury.

Injured tissue within 36 hours after injury

1 Limit and reduce activities so that damaged tissue is properly rested so as not to aggravate symptoms.

2 The application of cold therapy (for those who have cardiovascular disease and poor limb circulation with caution) aims to accelerate vasoconstriction, reduce bleeding, relieve pain, and relieve muscle spasms.

Cold Therapy Trick

1 Ice wipe: Wrap the ice cubes with gauze or wipe the damaged parts and surrounding tissue directly with ice cubes. Rub once every 5-10 minutes, 4-5 hours, and once every 5-6 hours on the second day.

2 Place the damaged part in the ice-water mixture for 30 seconds (skin flushing), and then put it in until the feeling returns to normal. Repeat for 3-4 times per group, 5-6 groups per day;

3 ice packs or chemical ice (can also take some frozen items from the refrigerator, wrapped with a cold towel wrapped in the wound), 20-30 minutes each time, 3-5 hours repeat;

4 Cold towels apply ice water, replace it once every 20-30 seconds, repeat once every 1-2 hours, and repeat once every 4-5 hours;

5 Break the ice into a thin plastic bag and place it in the wound for 20-30 minutes. Repeat for 3-5 hours.

6 cool water brewing not less than 5 minutes;

Pressure dressing

(Inner application of new wound No. 1 drug is better) can reduce the swelling and bleeding, with high elasticity self-adhesive bandage or other suitable device to protect the injury site, winding from far to near, sleep can be removed (after injury It is best not to remove in 24 hours).

If the limbs are damaged, in order to reduce the accumulation of body fluids, the affected area should be raised moderately.

24-48 hours after injury

1 closure therapy;

2 warm water therapy, Chinese herbal fumigation, light salt water soak;

3 physical therapy such as ultrasound, ultrashort wave therapy, etc.;

4 massage and massage;

5 acupuncture therapy;

6 He Lin et al.

Treatment of chronic injuries

For chronic injury, it needs to be diagnosed by a professional doctor and then given different treatments according to specific conditions. As the saying goes, no matter how good the knife wounds are, it is better to avoid prevention. Strengthening prevention is a problem that every physical exerciser must pay attention to.

1 Emphasize and do a good job of pre-workout activities. Stretch muscles and ligaments well enough;

2 Training should follow the principle of starting with a small amount and following a gradual and orderly process. With proper exertion, the exercise time at the beginning should not be too long;

3 Should pay attention to physical exercise at ordinary times, improve muscle strength and flexibility, so that they can adapt to the intensity of tennis;

4 to strengthen the protection of vulnerable parts, adhere to the use of support belts, such as elbow pads, wrist guards, knee pads, shin guarding, nursing calf, etc.;

5 Grasp the treatment of emergency injuries, pay attention to rest after injury, and reduce the possibility of acute injury becoming a chronic injury;

6 Do a good job of finishing activities after training to fully relax your muscles.

"famous" tennis injury

Tendon tendon rupture (tennis leg)

Diaphragm tendon rupture is more common in tennis players, hence the name "tennis leg." Diaphragm is a degenerative muscle with short muscles and slender muscles. Its injuries often occur when the knee joint is stretched, and the foot suddenly raises the moment of jumping. A minor injury affects the movement. When one hears the sound of a crack, or feels a "pain or shot" in the lower leg, it is very painful. It is difficult to walk after injury. The pain is intense, swelling, subcutaneous congestion, and joint activity is significantly limited.

In addition to the above-mentioned early treatment of tennis leg, it should be noted that the early stage of bed rest should place the ankle joint in a position of 90° back extension, and should get out of bed early (24-48 hours). Heel, after 48 hours, possible manual treatment, partial closure therapy or physiotherapy.

To prevent the tennis leg, we must strengthen the strength and flexibility training of the posterior group muscles. Before each exercise, especially when the weather is cold and rainy, we must make preparations. During the exercise, we can protect the calf or elastic bandage. After exercise, we should carry out ankle joint back. Practice stretching 50-100 times.

Tibial epicondylitis (tennis elbow)

The disease is caused by the excessive extension of the wrist joints and causes damage to the generalized tendon of the wrist and its vicinity. In most cases, it gradually appears due to the accumulation of small injuries, and it is also caused by one-time injury.

The clinical feature of tennis elbow is that when the movement is performed, the external elbow feels pain when doing certain actions, most of them have no obvious history of trauma, the symptoms gradually increase, the pain becomes persistent, and even the nighttime pain affects the sleep, and there may also be a sense of powerlessness. The phenomenon of falling objects.

Treatment programs

1 In the early days, you can reduce or rest during the activity and wait until it is not painful. You can also use topical drugs such as Futaline to wipe it. (Note that it is best to soak in warm water for a few minutes before applying the drug, and then apply about 2-3 ml of the drug. Apply it to the affected area and rub it with your fingers for better results). Some people say that the effect of drug treatment is not good, sometimes it is a problem with the method of drug application

2 massage therapy, physical therapy, closure and other effects are very good.

3 Wear an elbow when exercising or wrap the forearm with an elastic bandage.

4 surgical treatment, for long-term treatment and serious impact on life, feasible arthroscopic surgery or incision surgery.

To prevent tennis elbow, extensor stretching exercises can be performed, such as:

a. Elbow flexion 90 °, the wrist joints do palms flexion forward rotation exercises, 50-100 times / day, can be divided into 2-3 groups of exercises;

b. Extend the extensor muscles and have a sore sensation of 50 degrees (±) per group, 2-3 groups per day;

c. Extensive self-massage muscles, with pressure, kneading, holding, and pinching, with a sense of soreness, each 10-15 minutes, once daily
