According to the theory of spinal surgery, long-term low head ambulation work, the cervical spine is always maintained in a forward-flexed position, and the posterior cervical muscles are under tension for a long time, which can easily lead to cervical small joint disorders, cervical collar muscle strain, drop pillow, collar and back muscle fasciitis and even cervical spondylosis. Often the neck and back muscle pain and discomfort, cervical spine activity is obviously restricted, some manifestations of the upper limbs of severe radioactive pain, numbness of the upper limbs, can also be manifested as panic, insomnia, headache, dizziness, nausea, vomiting, etc., when the condition is serious, even walking unstable, such as stepping on cotton-like feeling, often painful. Swimming, especially breaststroke, when exhaling, should be low rowing, and when inhaling, the head and neck should be tilted backward and upward from parallel to the water surface, so that the head and neck are always in a low and tilted state, which is exactly in line with the requirements of functional exercise for cervical spondylosis, which can comprehensively move the joints of the cervical spine and effectively promote the repair of the strained muscles and ligaments around the neck; and when swimming, the upper limbs should paddle hard, which can exercise the corresponding muscle groups around the shoulder joints and the back. At the same time, when people paddle in the water, the friction generated by the water on the body and the pressure generated by the water on the body, the muscles of various parts of the body, can play a good massage effect, which can also promote the blood circulation of the skin and muscles, enhance the metabolism of cells.
