In the autumn season, swimming is the most popular popular sports nowadays. Sports injuries caused by swimming, swimmers should take timely precautions. “Swimming shoulder” is relatively common, but most swimmers are still very unfamiliar with it and easily ignore it. “Swimming shoulder” is a shoulder injury caused by excessive movement of the shoulder during swimming, and its scientific name is “shoulder impingement syndrome”. In chronic injuries, the rotator cuff is painful when the shoulder is abducted, but the shoulder can still be abducted, etc. The essence of “swimming shoulder” is the chronic inflammation of the soft tissues (tendons, muscles, ligaments) of the shoulder. How can I avoid swimming shoulder? For the average swimmer, the intensity of the exercise should not be too high, and a few round trips in the pool should be enough for a short break; one hour per swim is appropriate. Of course, each person is very different, and should be based on their own physical condition. Compared to swimming positions, freestyle, butterfly and backstroke are more prone to “swimming shoulder”, while breaststroke is better because the basic position of breaststroke determines that the range of shoulder activity is smaller than other swimming positions. During swimming, once you feel discomfort in the shoulder joint, avoid similar movements and reduce the amount of exercise; if the discomfort worsens or pain appears, stop the exercise and seek medical attention. Generally speaking, if you feel a little tired after swimming, it is muscle fatigue, which will disappear after a few days of rest. If there is pain, it may be inflammation, and there is a potential problem of “swimming shoulder”, so you may want to put a pain relief patch on the painful part of the shoulder, or do some local physical therapy, so that the shoulder pain will be reduced. If the pain is severe, a professional physician will need to determine whether to perform local seal treatment under the shoulder peak. After the pain is reduced or the inflammation gradually subsides, you should do some restorative shoulder activities or light training under the guidance of a specialist, do not rush to go swimming for a period of time, and avoid lifting heavy objects in your life. We hope that we can strengthen our awareness of sports protection, and once the injury occurs, we should ask a professional sports medicine doctor to evaluate the condition and develop a scientific rehabilitation and treatment plan, so that we can get a better post-injury recovery and return to the sports field with more confidence in the future.
