We examined the scientific nature of the basic exercises of ballet to spinal training from the perspective of anatomy. Pelvis is the base of spinal column, its forward lean or not, it is the muscle group control by coxal, flabby when pelvis is forward lean, can cause the bad posture such as carry out a bosom, hollow waist, warped buttock, hump. Accordingly, want to reduce pelvic forward tilt, make flabby coxal muscle group is tense rise, ability corrects undesirable motion posture. We ask students to stand on both feet facing the pole. Lean forward slightly with your hands on the handle. The knees should be straight, the leg muscles should be tightened, the gluteus muscles should be tightened, the abdominal muscles should be tightened, the back muscles should be tightened, the shoulders should be relaxed and slightly opened back, the shoulder blades should be lowered, the head should be straight, the face should be calm, the breathing should be normal. One of them. The head maintains the straight request to have three points: first, cannot lower the head; Don't tilt your head: don't extend your neck forward. Abdominal muscle is tightened also answer from 3 respects to ask: 1, tighten lower abdomen to go up top; 2. Hold your stomach; 3. Hold the ribs. Inspire the students to think of their ribs as old-fashioned Windows. Fasten them with bolts and do not push them away. Prohibit the outward expansion of the ribs and form the wrong chest out movement.
In the dance. The "chest out" movement is controversial. "Chest out", "head up" this word, will appear in the middle and primary school classes, whether it is culture or physical education, the teacher will ask students: sit and sit. Stand still. The students who are so tired that they lean over their desks should "hold their heads up" and "hold their heads up"; Tired of hunched back, head bowed in the playground queue of students to "chest", "head up". Ballet training in the upper body of the standing posture is: upright, pull back, keep the head straight. Opera requires "upward qi", ballet requires "downward qi, upward idea".
Let's compare, "chest out" and "back out"; "Lift" and "sink". Two very different concepts. Two opposite training methods. Past and present, tradition and today, from which we get some enlightenment: the history is developing, the society is progressing, the big wave is washing away the sand, the unreasonable part in the teaching material is bound to be eliminated. According to professional requirements on the body to pull out requirements. Only the four physiological curvature of the human spine: cervical vertebra, thoracic vertebra, lumbar vertebra, sacrococcyx vertebra are in the upright position, only in line with the standards of ballet training, the human body is artistic. At this time. The height of the human body is at least two centimeters higher than that of people without basic ballet training. Make the human body in an optimal, scientific state.
