When flying a kite, you can keep your chest up and head up and look to the right and left to keep the muscle tension of cervical vertebrae and spine, keep the elasticity of ligaments and the flexibility of vertebral joints, which is conducive to enhancing bone metabolism, strengthening the compensatory function of cervical vertebrae and spine, and preventing the degeneration of vertebrae and ligaments. Kite flying is not only a good way to prevent cervical spondylosis left by our ancestors, but also a comprehensive sport. In addition, flying kites in a wide area is the best way to take a bath in the air and sun. Swimming The function of swimming is to exercise muscle strength in the water, and it can also use the buoyancy in the water to relieve the joints that are normally under pressure, the most obvious of which is the waist. In addition, swimming can do some exercise movements that can not be done on land, can make the whole body more muscles, joints, ligaments to get exercise, muscle proportional development, good support and protection of the spine, the human body shape more beautiful. Swimming is also a combination of tension and relaxation exercise, the excitation and inhibition of the central nervous system to play a regulatory role, and insomnia, forgetfulness, depression, neurasthenia and other diseases have a special therapeutic effect. Cycling In cycling, the rhythmic stretching and contraction of the hip and lower limb muscles has a good protective effect on the spine, and can enhance the coordination of the whole body muscles and enhance the neuromuscular reactivity, flexibility and coordination. Long-term exercise can also improve the body’s cardiopulmonary function. Because the bicycle is a labor-saving tool, the intensity of the exercise can be controlled at will, the speed can be flexible, convenient and safe, and the site requirements are not high, as long as the flat road can be, and therefore is particularly suitable for white-collar workers. Mountaineering is a full-body exercise, especially for the lumbar back muscles, quadriceps, posterior femoral muscles, calf extensor and flexor muscles and small muscles of the foot exercise effect is greater, the strength of the lumbar muscles on the spine also produces a good stabilizing and protective effect, to prevent the occurrence of neck and back pain. At the same time, mountaineering is also a form of aerobic exercise, which is 2 to 3 times higher than jogging, therefore, often mountaineering can significantly improve cardiorespiratory function. In addition, mountaineering also has a good effect on the nervous system, in the process of mountaineering, the natural environment stimulation of the cerebral cortex can play a good regulatory role. Take the stairs The earliest advocate of the stairs fitness exercise is the American health authority Kenneth. Cousin, he believes that taking the stairs is an aerobic fitness exercise, beneficial to the body’s muscles and the whole body endurance. Since then, more research shows that: often take the stairs can not only enhance the lower limb muscles and ligament endurance, to maintain the flexibility of the lower limb joints, and because the waist, back, neck and upper limbs with the lower limb movement, so that this part of the muscles, ligaments and so on can also be effective exercise. At the same time, the human body’s respiratory, cardiovascular and other system functions can also be improved through exercise. In addition, take the stairs to reduce blood cholesterol and improve the content of high-density lipoprotein, to prevent atherosclerosis, hypertension, obesity and prevention of back and leg pain has a significant effect. Some experts have found that a person who climbs 5,000 stairs a week has a 25% to 33% reduction in mortality than those who do not exercise. 5,000 stairs per week, calculated on a 7-day week, means more than 710 stairs per day, equivalent to 30-40 floors, which is not difficult for the average white-collar workers, work, work, home, shopping malls without taking the elevator, a day can be completed unconsciously exercise.
