How can I not get dizzy?What is the secret of figure skater?

The Beijing Winter Olympics are in full swing.These days, Gu Ailing’s 1620 and Yuanyu Yuxian’s 4A have swept the screens of major networks, jumping in the air and turning around…While cheering for their spectacular performance, did you also wonder how these athletes, especially figure skaters, manage to stay balanced and not get dizzy with so many turns on the ice and snow?After all, as normal people, we get dizzy after two turns, and some of us even get dizzy without turning.All of this has to do with one of the most important structures for maintaining balance in our bodies: the vestibule.Zhang Hongzheng, director of the Otolaryngology Head and Neck Surgery Center at Zhujiang Hospital of Southern Medical University, explained that our bodies need vestibular, visual and proprioceptive senses to work together to maintain balance.Problems with any one of the three can give us symptoms like vertigo and unsteady walking, and the structures most likely to produce vertigo and instability are the vestibular organs.The vestibular organs, located in the inner ear, consist of three semicircular canals and two otoliahs (oval sac, balloon).The three semicircular canals sense head rotation, producing an angular acceleration when the head rotates or tilts, and the three semicircular canals detect angular acceleration in different directions at three relatively vertical levels, which are then integrated into neural impulses sent to the brain.The two otoliths detect linear acceleration and continuously transmit the felt nerve impulses to the center.They are integrated with nerve impulses received by vision and proprioception to maintain the body’s balance.Inside the semicircular canal are lymphatic fluid and the ampullary crest, which is like little bits of seaweed floating in the fluid, sensing what’s going on.When continuous rotation with a large range, the ampulla eminence hair cells of the semicircular canal are overstimulated. Without training, the tolerance of the vestibular center of ordinary people will be slightly worse, so ordinary people will be dizzy and unstable after several rotations.But In the men’s singles free skating final in Beijing, Chinese-American Chen Wei completed five quadruple jumps.And statistics show that in a major figure skating competition, four and a half minutes, the average figure skater will make nearly 100 turns.Why do they make so many turns and land smoothly at the end?Director Zhang Hongzheng explained that this needs to rely on a large number of scientific vestibular function training, so that the original reaction caused by rotation or various acceleration stimulation is constantly reduced, or even disappear, so that their balance system in the complex and rapid rotation process to find their own balance point.Normal activities have dizziness, may be the otolith off in addition to the majority of people turn two laps is easy dizziness, and some people even without circle, just do some normal head movement, also can produce very dizzy, stand suddenly feeling, this time is likely to be the problem of vestibular function, which is one of the very common otolith.As mentioned in the previous article, the vestibular organs also include two otoliths, oval capsule and balloon, which are covered by otoliths and contain otoliths. However, under such circumstances as vestibular inflammation, strong impact, or ion metabolism imbalance, the otoliths may fall off.Falling into the semicircular canal or adhering to the crest can cause vertigo, which is called otoliths.In simple terms, the “crazy rock” in the ear has escaped to other parts of the ear.The high incidence of otoliths is after the age of 40, some special groups of people will also appear in advance of aging, such as weak women, as well as long-term exercise, pressure, have sleep disorders white-collar group also belongs to the high-risk group.However, Zhang hongzheng, director of otoliths, said that otoliths are not a terrible disease. In most cases, otoliths can be treated by manual reduction. In short, the removed otoliths can be put back into the oval capsule, and sometimes drugs are used.Article/Yangcheng Evening News full media reporter Zhang Hua correspondent Wu Xiaodan Jiang Shanshan Lin Mian map/visual China to learn more
