Swimming is not only a survival skill, but it can also strengthen the body and prevent and improve certain diseases. Among the exercise therapies in rehabilitation medicine, swimming as an aquatic exercise method has been widely used by hospital rehabilitation departments to advise patients to prevent and treat a variety of health disorders through swimming. Prevention and treatment of cervical spondylosis – breaststroke is the most suitable Mr. Chen has been fully engaged in the company’s business for many years, overtime has become the norm for many years, until after exhausted body to feel regret. Forty-something years old, he looks like the age of more than fifty years old. Due to the usual do not pay attention to maintain the correct sitting posture, often reading documents, Mr. Chen’s cervical vertebrae gradually “injured”, often feel sore and unbearable. On the advice of his doctor, Mr. Chen insisted on swimming 2-3 times a week. Together with proper treatment, the pain of the cervical spine slowly reduced. Although swimming is not a treatment method for diseases, it can play a preventive health role for diseases. Swimming is suitable for the treatment of orthopedic diseases, including post-fracture sequelae, osteoarthritis, ankylosing spondylitis, rheumatoid arthritis, compression fracture, myotonic dystrophy, hemiplegia, cranio-cerebral trauma and other diseases. Swimming can largely help prevent and treat cervical spondylosis. Swimming is a whole body exercise, the upper limbs, neck and collar, shoulders and back, abdomen and lower limbs of the muscles are all involved. When people row 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, can effectively promote the blood circulation of the muscles of the whole body. Long-term adherence to breaststroke, can effectively improve the cervical discomfort, neck, shoulder and back pain is expected to be relieved. Improve spinal disease – relax the spine best There are scientific research analysis, the human thigh and spine angle to maintain at 135 degrees, the spine can get the best relaxation. In swimming, most of the time in the horizontal position, the torso and limbs only have to overcome the resistance of the water without overcoming gravity, the spine can also be well relaxed and adjusted. When swimming forward, the top of the head, straight neck and back, straight hips and legs, such an angle can best relax the spine. There are many swimmers who suffer from spinal disease is through swimming exercise, unknowingly healed. Regular and moderate swimming exercise can guarantee the nutrition supply of interspinal tissue, thus maintaining its elasticity and improving the ability of the spine to resist external shocks. At the same time, the action of swimming upper limb paddling can move the shoulder joints and back muscles, and the action of tilting the head to inhale can move the cervical joints; and tilting the head to inhale and head down is the opposite of two movements, which can promote the repair of spinal strain muscles and ligaments. In addition, knee joints, ankle joints, etc. do not have to run or walk like continuous force, can get relaxation and rest, which helps the joint inflammation and joint function recovery. Reduce allergies and strengthen resistance It is generally believed that swimming can also strengthen resistance and avoid allergies. There are many reasons for allergies, and poor body resistance is an important factor that cannot be ignored. Compared with other forms of exercise, swimming is characterized by better body resistance, exercise of all parts of the body, and enhanced lung capacity. The water temperature in the pool is relatively low, through the stimulation of cold water can improve the body’s ability to withstand cold, so as to achieve the effect of strengthening physical fitness. When swimming, the water flushes the skin, sweat and fat glands, which not only promotes blood circulation, makes the skin smooth and elastic, and greatly reduces the stimulation of the skin by the salt in the sweat, which all help to reduce the chance of allergies. However, if the person is allergic to chlorine, it is not very suitable for swimming. If you want to strengthen your resistance and reduce allergies through swimming, when you make a swimming plan, the amount and frequency of exercise should be increased gradually from less to more, in order to be comfortable, and you must do it according to your ability. Also pay attention to hygiene, to prevent infectious diseases. Weight loss and slimming – consume calories to repair the body shape Exercise is the most common method of weight loss, and swimming physical energy consumption, is the first choice of many women to lose weight. Swimming can “lose weight and slim down” because swimming is indeed a calorie-consuming aerobic exercise. The energy consumed by staying in the water at 12 ℃ for 4 minutes is the calorie consumption of an hour of land exercise. The density and thermal properties of water are greater than air, so the energy consumed by swimming is also more than other sports. The energy consumed by swimming relies mainly on the sugar and fat in the body to replenish. Therefore, swimming can gradually reduce the excess body fat. At the same time, swimming can improve the mobility of the muscular system, improve the flexibility of soft tissues. Long-term exercise can make muscle strength, speed, endurance and joint flexibility are improved. People who engage in regular swimming activities become more flexible and supple. However, to lose weight through swimming, you must achieve a certain level of intensity, stick to it for a sufficient amount of time, and be persistent.
