Xiao Li is a young female dancer who has just joined the song and dance troupe. She is very active in practice, arrangement and performance. Recently, the director decided to let her play the leading role in a newly rehearsed dance, not to mention her happy appearance. In order to finish this task, she practiced harder and harder. Unfortunately, in the afternoon, I suddenly felt very tired, with backache, headache, emotional instability and depression. After a while, I feel pain in my lower abdomen, so I'm going to have my period. She is very nervous and doesn't know if she can continue to attend the rehearsal. She immediately went to see Dr. Ling, an old doctor with more than 20 years of clinical experience. After Dr. Ling's patient and convincing answer, Xiao Li relieved his worries and happily participated in the rehearsal of the new program. The following is an excerpt from their conversation: Xiao Li: "Dr. Ling, I heard that not menstruating will ruin your health." I feel a little uncomfortable these two days, with backache, fatigue, boredom, constant sleepiness, stomachache and tense rehearsal tasks. What should I do? Ask Dr. Ling for health guidance. "Dr. Ling:" The symptoms you mentioned are normal during the menstrual period of ordinary people, so there is no need to make a fuss. Most of these phenomena are related to the excitability changes in the cerebral cortex, which will naturally disappear after menstruation. Some people say that you can't exercise during menstruation, and jumping will ruin your body. There is not much scientific basis. Proper exercise and reasonable arrangement of program rehearsal will not only ruin your health, but also benefit your health. "Xiao Li:" I heard that Dr. Ling advocated female dancers to keep training during menstruation. I wonder if there is any experience in this field at home and abroad? "Dr. Ling:" Can female dancers participate in practice or performance during their menstrual period? Can their performance level be high? What's the effect on her health? "This problem is often encountered. Recently, I came into contact with some old doctors who are very experienced in sports medicine to discuss this issue together, because the training and performance of female dancers have many similarities with the training and competition of female athletes. They investigated 50 female track and field athletes who participated in the training of the 8th Asian Games, and found out their menarche age, menstrual cycle, whether they participated in training and competition during their menstrual period, and whether it had an impact on their health. 86% of the 50 female athletes are under the age of 23. The shortest time to participate in special sports is 3.4 years, and the longest is 8. 1 year. Their average age at menarche is 15.2 years old, their average menstrual cycle is 29 to 3 1 day, and their average menstrual period is 4.6 days. There is no obvious difference with normal women in China. Fifty female athletes have different menstrual reactions. 70% premenstrual patients feel low back pain; 54% people feel pain in the lower abdomen; 40% felt breast swelling; Among them, 54% people have poor physical strength before menstruation and can't lift their spirits; 46% female athletes get excited easily before menstruation, but no one stops training and competing. Although 74% female athletes will feel back pain during menstruation; 58% people feel mild abdominal pain, but 74% of these female athletes can participate in training and competition during menstrual period. Sixty-eight percent of female athletes can maintain their original level in the competition. Among them, 24% can hit a high level, and some can break the national record. After training or competition, 80% female athletes feel normal, and there is no particularly uncomfortable feeling caused by fierce competition, or it affects their menstrual cycle and period. Therefore, I think that female dancers will not have too many adverse reactions to the human body if they properly participate in practice or performance during menstruation. This survey material is very convincing, you can take it to have a detailed look. In addition, according to the theory of traditional Chinese medicine, exercise can improve the blood circulation of pelvic cavity and prevent congestion. Because the contraction and relaxation of abdominal muscles and pelvic floor muscles during exercise have a gentle massage effect on the uterus, which helps to discharge menstrual blood and relieve pain in the lower abdomen, it may have certain benefits. " Xiao Li: "I don't have any worries after hearing what Dr. Ling said, but what problems should I pay attention to during menstruation?" Dr. Ling: "Yes, that's a good question. We should have both revolutionary enthusiasm and scientific attitude, and we should not blindly act recklessly. In the case of excluding pathology, I advocate that female dancers participate in exercise or performance during menstruation. But we should also avoid some drastic actions, such as high-intensity waist and abdomen muscle exercises and intense high-intensity jumping exercises. We advocate proper exercise or performance during menstruation, not blindly and recklessly, but scientifically. Especially a young female dancer like you who has just entered the song and dance troupe, you should pay more attention. When practicing, don't jump too hard and do abdominal movements, and don't hold your breath and exert too hard, so as not to cause increased intra-abdominal pressure, increased uterine pressure and excessive menstrual blood. To scientifically arrange the amount of exercise, the best arrangement is to practice some small movements on the first and second day of menstruation; Gradually increase the amount on the third and fourth days of menstruation; You can practice or perform as usual on the fifth and sixth day of menstruation. For those female dancers who work long hours, they can participate in practice or performance as usual. In order to master the menstrual situation of young female dancers, it is best to establish a menstrual card system in order to scientifically arrange the amount of practice. " Xiao Li: "Thank you, Dr. Ling, for giving me a vivid health lesson."
