This is my major! I feel very rewarding! It's easy to find a job now. I can be a club fitness coach, a group gymnastics coach, an aerobics teacher and a physical education teacher. More importantly, it has great value: aerobics not only has the value of exercising and strengthening physical fitness in general sports, but also plays a special role in reducing weight, shaping body shape, improving rhythm and body coordination of women.
(A) the movement system
Long-term practice of aerobics is conducive to the symmetrical and harmonious development of muscles, bones and joints, and is conducive to improving bad posture and shaping beautiful figure. Aerobics is a coordinated activity of various muscle groups and joints of the human body. Due to the strengthening of muscle activity, muscle fibers can be thickened and strengthened; It can effectively enhance the elasticity of tendons and ligaments and the toughness and flexibility of joints. Due to the enhancement of muscle strength, excess fat can be eliminated, and dull muscles can be softened and rejuvenated. Proper aerobic exercise can promote the normal development of children, enhance the development of bones and muscles of teenagers, rejuvenate the elderly, delay aging and prolong life.
(2) For internal organs
Regular aerobic exercise has a good influence on cardiovascular system, respiratory system, digestive system and internal organs. It will gradually thicken the myocardial fibers, thicken the myocardium, contract strongly, increase the cardiac output, improve the blood supply capacity, and increase the elasticity of the blood vessel wall, thus preventing the occurrence of cardiovascular diseases. Through long-term aerobics aerobic exercise, people's breathing deepens, the breathing frequency decreases and the oxygen intake increases, which can make the breathing muscles get full rest and promote good metabolism. Through all-round exercises such as waist, abdomen and buttocks in aerobics, gastrointestinal peristalsis is strengthened and digestive juice secretion is promoted, thereby enhancing digestive function and promoting human metabolism, which is conducive to the absorption and utilization of nutrients.
(3) For the nervous system
The exercise value of aerobics on nervous system lies in relieving mental stress, enjoying body and mind, and improving nervous system function. Aerobics is carried out under the control of the central nervous system. On the other hand, aerobic exercise can improve the functional level of the central nervous system, the intensity and concentration of nerve processes, broaden people's horizons, sharpen their senses, enhance their comprehensive analysis ability, have strong vitality, better control and adjust the vitality of various organs and systems of the human body, and ensure the coordination and unity between the human body and the external environment. At the same time, the route, direction, speed, type and intensity of aerobics movements are constantly changing, which can strengthen people's action memory and reproduction ability and improve the flexibility and balance of the nervous system. Especially for students who have been working hard for a long time, musical aerobics can quickly achieve the effect of relieving tension, thus ensuring good work and study efficiency.
