Will the early exit of the new national husband Zetao Ning be the injury effect of swimming?

A few days ago, [Little Fresh Meat] Zetao Ning stopped in the semi-finals of the 100m freestyle event. Early this morning, news came from the front court of Rio that Zetao Ning was eliminated in the 50m freestyle preliminaries, which made people pinch a cold sweat.

In spite of this, fans of young girls all over the world continue to add Shi oil (AI) to Zetao Ning on Twitter. I have to say that a perfect figure and a good face will always be so outstanding in the swimming pool…

This figure is enough.

On the other hand, of all athletes, swimmers often have the best body shape-the balanced muscles of the whole body can not only let fans’ hormones overflow, but also bring great protection to themselves.

Although there are more swimmers, compared with other sports, we have seen quite little news of serious injuries to swimmers. At present, the news mainly believes that Zetao Ning is not the cause of injuries but the poor training and competition.

Is swimming really the least vulnerable sport? What are the most common injuries caused by swimming? What would the doctor suggest? Clove Garden will tell you about this problem from the perspective of sports medicine.

Is swimming really less vulnerable?

Swimming has always been regarded as the sport that causes the least injuries. Compared with resistant sports such as basketball, equestrian and football, swimming does rarely cause serious sports injuries.

In the past large-scale competitions, there were few accidents in swimming events. But there were also very shocking incidents.

For example, on March 21, 2007, Zhou Yanchun, a 17-year-old national first-class athlete, drowned while training in the swimming pool in Hongkou District of Shanghai. The specific cause of drowning is not clear.

Another example is Luo Xuejuan, a Chinese swimmer, who fainted twice in the Athens Olympics in August 2004 and was unable to support himself ashore. On January 29, 2007, Luo Xuejuan, who was only 23 years old, officially announced his retirement due to illness.

So far, there is no direct evidence that swimming is prone to heart disease. Moreover, compared with other sports, the proportion of swimmers suffering from heart disease is very low. However, this may suggest that people with heart diseases should swim carefully and finally consult a professional cardiologist.

A must-know [swimming injury]

Compared with other sports, such as football, basketball and other confrontational sports, accidental injuries occur from time to time on the field, and accidental injuries caused by swimming on the field are very low.

However, swimming is the exercise with the highest frequency of shoulder joint use, and repeated stroke in daily training is an important factor causing shoulder joint pain.

At each stroke cycle, The arm needs to complete the movements of entering the water, stretching the arm, paddling, exiting the water and moving the arm in the air. Repeated actions lead to fatigue of rotator cuff muscle group and scapular stabilizing muscle group, which makes scapula lose stability, increases the possibility of humeral head displacement, and may cause subluxation or even complete dislocation of shoulder joint. Soft tissue around shoulder joint is under excessive pressure, resulting in inflammation and pain of shoulder joint.

The most common training-related injury is [subacromial impingement syndrome]. Some people also refer to subacromial impingement syndrome caused by swimming, glenoid labial structure injury of shoulder joint and related shoulder joint dysfunction as [swimming shoulder].

Some swimmers suffer from shoulder pain after swimming. Some people cause pain when the shoulder is abducted. Some occur when the shoulder abducts to 90 degrees and some occur when the shoulder joint is adducted. Others occur during shoulder flexion. Some patients are accompanied by rattling or stiffness in addition to pain when lifting or rotating on the shoulder, and even some patients will feel unstable in the shoulder joint at a specific position, resulting in limited shoulder joint function, serious cases will affect sleep, and even chopsticks cannot be held.

Shoulder impingement syndrome is divided into three phases:

1 期: 急性炎症, 水肿和出血, 伴有肌腱炎或滑囊炎, 非手术治疗可恢复
2 期: 慢性炎症, 纤维化或肌腱炎, 反复疼痛, 手术治疗
3 期: 肩袖完全断裂, 渐进性功能丧失, 前部肩峰成形术, 肩袖修补

Shoulder joint injury is usually found earlier, the earlier the treatment, the better the effect. Therefore, friends who like swimming should seek medical treatment in time if shoulder joint discomfort occurs. They can go to joint surgery, sports medicine or sports rehabilitation.

When you are not aware of shoulder pain and discomfort, you must hold the idea of “just endure it” or take painkillers (such as fortalin) orally for a long time and continue to exercise forcibly. This often only aggravates the disease and may lead to serious consequences of rotator cuff tear or joint dislocation.

Some Suggestions for Preventing Shoulder Discomfort in Swimming;

(1) Make sufficient preparations to warm up before and after swimming, especially the shoulder, hip and knee joints;

(2) Pay attention to maintaining correct swimming skills, and can consult a professional swimming coach;

(3) Avoid actions that cause pain, reduce the amount of training and take timely treatment measures when pain occurs;

(4) Pay attention to pulling the anterior and posterior joint capsules of shoulder joint after swimming.

As long as the method is proper, swimming is indeed a recommended sport, which can be used as both a fitness and a survival skill.

Recommended for middle-aged and elderly people with knee joint problems

Compared with basketball, running, cycling, mountaineering and other sports, swimming has little influence on ankles and knees.

Taking swimming as a long-term and regular sport has more advantages than disadvantages. However, remember that you must keep the frequency 2-3 times a week, and each swimming time should be more than 40 minutes, excluding bathing and chatting time!

When swimming, the resistance of the water makes the muscles exert moderate force. These characteristics are very suitable for the exercise of the middle-aged and the elderly. It is not easy to have accidents due to too much exercise. However, it must be a friend who does not have serious diseases such as heart disease and hypertension.

In addition, long-term swimming can improve muscle strength, speed, endurance and joint flexibility.

It is best to learn swimming in what?

If you look at Olympic swimming, you will surely envy the swimmers for their round, slender, properly proportioned muscles and strong bodies.

Adolescence is the peak stage of musculoskeletal development. Swimming training at this time can well shape a perfect figure, and can maintain balanced bone development on both sides of the body, straight spine, wide shoulders and narrow buttocks, and developed upper limb strength.
