Swimming in the Summer Olympic Games is the most eye-catching event.
Swimming is also one of our daily summer exercises.
While enjoying this pleasant refreshing.
After exhausting the power of the flood in the body
Have you paid attention to whether your posture is normal?
Does your shoulder hurt?
Swimming is a good aerobic exercise, but if we don’t pay attention to our posture and swimming movements, all kinds of injuries will come to us, especially the "swimming shoulder". In our opinion, there is a great relationship between bad posture and "swimming shoulders".
Body posture is related to shoulder pain.
The posture can be seen from both sides.
Posture or body posture is actually the relationship between various parts of the human body and joints in space. He is generally divided into dynamic and static:
When we stand in front of the mirror, we can evaluate whether our posture is normal at rest by observing the position of our body from head to toe from the front, side and two angles.
From the front, a straight line is drawn from a person’s head, from the lower meridian between the eyes, to the nose and mouth all the way along the trunk, and to the two toes of the legs. If the body is just divided into two symmetrical halves by this straight line, and the shoulders, elbows, hips, knees and ankles are balanced, it shows that this posture is healthy.
From the side, if you can form a vertical line from the ear, through the middle of shoulder joint, hip joint, knee joint, until the position slightly in front of ankle joint, it is a normal standard posture.
However, in practice, we find that many people, including many professional athletes, do not meet or even seriously deviate from the above standards. Some people may have the posture of one shoulder high and one shoulder low, or one shoulder forward and one shoulder backward, or even have different lengths of their legs because of congenital or developmental problems. Some people, after long-term swimming training, have developed local muscles, causing imbalance of muscle strength on both sides of the shoulder joint, especially the abnormal posture such as the deformation of the physiological curve of the cervical spine, hunchback of the chest, and internal rotation of both arms.
The human body is a power chain
The human body is a complicated but ingenious sports machine. No matter what kind of swimming posture, the swimmer is required to maintain a good body posture and correct technical movements in the water and move in a straight line as uniformly as possible. The human body is also a power chain that "pulls one hair and moves the whole body", and any tiny parts are interrelated.
If there is something wrong with the body structure or technical movements, even if it is only a part or a small link, it may make it difficult for swimmers to keep straight in the water and waste too much energy. It is common that when paddling, one hand is heavy and the other hand is light; When drawing water, one leg is heavy and the other leg is light. What’s more, if you do this for a long time, it will aggravate or bring sports injuries such as "swimming shoulders" to swimmers.
Many people have "swimming shoulders" and always attribute the cause to the shoulders.
In fact, as mentioned above, as a whole, it seems to be physically irrelevant, and it will also spread to the shoulders. For example, some people suffer from cervical spondylosis, and the physiological curve has changed shape, causing stiffness of shoulder muscles and even hunchback. At this time, it is difficult to raise your head. When swimming, it is inevitable that your movements will be out of shape, your strength will be difficult, and your shoulder load will increase, resulting in injury. There is a professional freestyle athlete who suffers from bone spurs in the ankle joint cavity, which makes him feel pain when kicking water and turning around. Therefore, when kicking water, one leg is heavy and the other leg is light. In this way, the opposite shoulder corresponding to the leg with heavy kicking water will inevitably increase its strength to maintain its balance. Over time, the load on this shoulder is too large, and a "swimming shoulder" appears.
Paying attention to posture is also paying attention to health.
Generally speaking, taking part in any sports has the following basic requirements for the body:
First of all, we must have a normal posture;
Secondly, joints should have normal mobility;
Third, we must have certain strength;
Fourth, we should have good joint stability;
Fifth, we should master reasonable sports techniques.
These requirements are also important factors to ensure physical health and prevent injuries during exercise.
Therefore, in order to prevent water sports injuries such as "swimming shoulders", you should have a comprehensive understanding of your body before going into the water. The easiest way is to stand in front of the mirror freely and check your posture from the front and side, whether it is symmetrical and balanced. Of course, if you have the conditions, you should go to a professional doctor.
Secondly, from the point of view of doctors’ diagnosis and treatment, we should remember to treat the headache rather than the foot pain. After the shoulder pain occurs, we should look for the reasons from many aspects, especially from the relationship between body posture, technical movements, training methods and physical load. This requires going deep into the reality of swimming and mastering relevant theoretical experience.
Thirdly, the coach can also understand and master the physical structure characteristics of each athlete and design reasonable technical movements from person to person. Athletes themselves should consciously make more efforts in this regard.
warming-up
There are also some swimmers who only pay attention to moving their shoulders and heads before entering the water, regardless of the shoulder straps, which makes the scapula not movable. Therefore, after entering the water, the mobility of the shoulders and the stroke range of the back arm are greatly limited, especially in freestyle and butterfly events, which will cause the humeral head to squeeze the rotator cuff muscles or the acromion descending capsule, causing impingement and forming a "swimming shoulder".
