The six-character formula of health qigong is a fitness method based on breathing, combined with action guidance and psychological adjustment. Its breathing mode adopts reverse abdominal breathing, which requires slight intention. According to the related theories and teaching practice, this paper analyzes the essentials and functions of the six-character formula of health qigong. As a dynamic exercise, the six-character anti-abdominal breathing method of health qigong has the same points as the anti-abdominal breathing method used in static exercise, but it also has different characteristics: the characteristic of health qigong is 1, and the six-character anti-abdominal breathing method of health qigong should be coordinated with body movements in practice, inhaling when the movement rises or opens, and exhaling when the movement falls or closes. Characteristics of health qigong II. The body movements of the six-character formula of health qigong can be transformed into ascending, descending, opening and closing, and the movements pause slightly at the transitional incision to reflect the combination of tightness and excess. Therefore, when using reverse abdominal breathing, it is necessary to make a short pause at the transition tangent point where the action is lifted to form "suction stop" reverse abdominal breathing. Characteristics of health qigong. Pay attention to the depth, length and even "depth" in the process of reverse abdominal breathing in health qigong, which means that the feeling of "breathing" goes to the lower abdomen (dantian), which is different from natural breathing. The feeling of "breathing" only reaches the chest; "Long" means that the breathing rhythm should be slowed down, and the time between inhalation and exhalation should be extended as much as possible to match the softness, slowness and completeness of the action; "Uniform" means that the whole process of air entering and leaving the body should be as uniform as possible from the beginning of inhalation to the end of exhalation. Characteristics of health qigong. The anti-abdominal breathing method of health qigong and six-character formula should be combined with the corresponding zang-fu organs when exhaling. The word "shh" means two threats; The word "ha" means lower chest; The word "Hu" means abdomen; The word "four" means upper chest; The word "blow" means waist; The word "Xi" means the whole chest and abdomen (triple energizer), which is carried out from top to bottom. Characteristics of health qigong. The anti-abdominal breathing method of the six-character formula of health qigong should not be too full when inhaling and too full when exhaling, leaving room for avoiding suffocation. What are the fitness qigong? The most commonly used breathing methods of health qigong are natural breathing and abdominal breathing, and abdominal breathing is divided into anterior abdominal breathing and reverse abdominal breathing. The breathing method of the six-character formula of health qigong requires beginners to breathe naturally when learning, and then reverse abdominal breathing after mastering the movements.
