See for yourself one answer: prepare for position. Faced with the net, the two feet were standing back and forth, the left foot was front, the two knees were leaning, the upper body was leaning forward, the weight of the back foot was heavy and the left hand was holding the ball in front of the belly. The left hand throws the ball gently on the right side of the front, about 20 cm above the right hand. With the force of the right foot, the weight of the body moves forward with the right hand to the front foot... When the hand touches the ball with its full hand or the lower side of the fist, the wrist of the finger is tense, the hand reaches straight... After the ball is hit, the weight moves forward with the punch. 2as: (1) cultural education function of sport, fitness function, physical function, physical function. (2) economic function of sport, promoting the development of urban infrastructure2 promotion of tourism, diet, service, etc. 3 promotion of employment opportunities. (3) political function of sport, enhancing national image, enhancing national prestige. 3 promotion of national self-confidence and pride. Action rate: is the number, or frequency, of repeated actions in unit time. Movement speed: is the distance (often described in m/s unit) from which a part of the body or body moves within the unit time. Movement force: is the ability of the body or part of the body to overcome resistance when the movement is completed. Action rhythm: the strongness and weakness of force in the various parts of the action is related to the time-spacing 4. Accuracy: (1) accuracy of action (2) coordination of action (3) strength of action (4) economics (5) flexibility of action: cross-line diameter, myoglobin reaction, contraction, fatigue red muscle fibres, poor, much, much, much, much, much, much, quickly: (i) physical and mental development patterns of students (ii) motor skills formation patterns 1.-perform process 2. 3. Automation stage 4. Automation phase 3. Physical activity in the harmonious development of psychological and social adaptation. School after-school physical education is an educational process in which trainers systematically train students who have some skills in physical education, develop their bodies in a comprehensive manner, continuously improve their sports performance and develop sports cadres and specialized organizations. The training is provided to students with sports specialties and exercise is a means of promoting student development for all students. 11a: the gas blood barrier is the structure adopted for gas exchange between oxygen in the pneumoconiosis and the blood carrying carbon dioxide in the pneumatic pelvis. It consists of six layers of structure: liquid layers containing pulmonary surfactant substances, pulmonary oscilloscopes, upper skin membranes, faults between pneumatic pneumococular uppers and phythmias (basic layers), base membranes in the pneumoculars and cortexes. 12a: this classification is based mainly on the relationship between environmental conditions and athletes. Closed skills are regulated mainly by feedback from the internal sensor of the athletes and are performed under relatively stable conditions. This type of motor skills requires that movements be as accurate and stable as possible, such as diving, leapfrogging, etc. Open skills require athletes to integrate information about the outside environment for decision-making, which is more dynamic, such as football and basketball. 13: (i) the initial formation phase (the pan-china phase) (ii) the improvement phase (the differentiation phase) (iii) the mastery phase (the consolidation automation phase) 14; during the process of operational skills formation, there was a temporary pause in the exercise, which over time continued to progress, and the curve became “highland phenomenon” or “highland period”. 15: 1. Horizontal migration is a phenomenon of skills transfer between various motor technologies that are difficult or of similar degree or level. Vertical migration refers to movements between technologies with different levels of difficulty in the same motor skills. 3. Cross-migration is a phenomenon where the effects of the exercise of organs on one side of the body can be shifted to the other. 16: the motivation for physical education is a psychological force for the development of physical education, or an internal motivation for students to study physical education. Interest is the psychological tendency of a person to seek to know, to master something, to participate in an activity and to have a positive mood ... Interest includes both the desire to learn and the desire to participate, whereas the motivation is only participation, i. E. Greater motivation. 17: the outside of the forearm is on the side of the cheek and inside is on the side of the ruler. The side is inside, the side is outside. The judgement is based on the internal side of the axis in the body, in accordance with the body anatomical position, far from the axis in the body. A kick on the inside of a foot means a kick on the inside of a foot, i. E. A bow close to the axis in the body. 18: the main aerobic muscles consist of muscular and rib exterior muscles. The aerobic muscles contract up and down while breathing, and the rib muscles shrink and expand. The excrete muscles mainly point to the muscular and intraribular muscles. 19 response: includes the nature, content, ph, pco2, temperature, organophosphorus compounds and co, among others. 1) when ph drops, pco2 rises, temperature rises, organophosphorus rises, oxygen moves to the right; 2) when ph rises, pco2, temperature, organophosphates decreases and co poisonings, curve moves left. Ph is inversely disproportionate to other factors: the function of the conversant neurosis: when the body moves, the virulent neuroactivity increases the heart rate, blood pressure rises, bronchial expansion, pupils open. The digestive activity is inhibited, indicating an increase in the metabolism of the organism and an increase in energy consumption to adapt to the dramatic changes in the environment. The function of the contour neuroactivity: contrary to the effects of synergetic neurons, the two are synergetic ... When the body is quiet and asleep, the synergetic neurons are excited, while the synergetic neurons are inhibited, and there are signs of reduced heart rate, slowing down, declining blood pressure, reduced heart rate, reduced blood pressure and increased digestive absorption. Psychic nerves speed up the heart beat and subsychic nerves relax and quiet. People get nervously excited when they move, their pupils get bigger, and their heart output increases. Reduced heart rate during rest, smaller pupils, leading by sub-temporal nerve 21 answers: 1. Resilient receptacles with a heart rate of 2. 0 eccentricity per beat output 4. 4. Outer eccentric resistance and arteries 5. 22 in relation to blood circulation and vascular capacity: physical properties include expansiveness, elasticity, viscerality. Physical properties refer primarily to excretion and constrictiveness. Muscular contractions are mainly carried out in the form of small muscle condensation, i. E. Fine muscle silk slip 23 responses to corrosal silk: phosphate, fermentation and oxidation systems. The three energy-supply systems will last 10 seconds, 1 minute and 30 minutes, respectively。the representative projects for phosphate are weight lifting, throwing, yeasting (emulsive acid energy) running 400 metres on behalf of the project and swimming 100 metres. The oxygen oxygen oxidation (oxygen oxygen oxygen oxygen) represents projects of durability such as long running and bicycles. Only oxygen-intensive systems are required. 24 response: in case of abdominal pain in exercise, the abdominal pain should be properly slowed, the breathing should be intensified to adjust the breathing and motion rhythms, the pain should be applied to the pressure, or the pain should run at a distance, and the pain should often be mitigated or disappeared. 25: the artery-repressed bleeding method: used for haemorrhaging on top and in the artery. Haemorrhage for external artery: haemorrhage for ribs and face. The general artery-repressive bleeding method is commonly used when hemorrhaging is not effective. Hemorrhage control: used in armpits, shoulder and upper limb bleeding. Hemorrhage control in the artery: haemorrhage in the hand, forearms and forearms. 26a: (1) early, for acute inflammation periods, the treatment principle for this period is to stop the bleeding, brakes, tremors, oscillations and de-inflammations.... The treatment method is cold dressing, pressurizing and lifting up the injured limbs, which can be applied to new injuries, as well as internal anti-heating, painkilling, active haematosis, etc.... (2) in the medium term, the organization is in the process of repair. The treatment principle for this period is to improve the blood cycle and lymphomy cycle in the wound, to promote tissue metabolism, to accelerate the absorption of silting and seepage and the removal of the necrosis tissue, to promote tissue metabolism, to accelerate the absorption of silmatoma and leachate, and to remove the tissue from the dead, to promote regeneration, prevent and reduce adhesive formation. (3) in the late stages, the damage tissue has been largely repaired, but there may be abrasions or adhesive formation. The treatment principle for this period is to restore and enhance muscles, joints and, where there are gills or adhesives, try to soften or separate. 27a: leg stop ball applies to a ball that stops vertically from the air, as the four-head muscles on the front of the thigh can act as a defibrillation. The ball that stops vertically on the back of the foot is also the ball that stops rolling. The chest stops mainly horizontally. 28a: sudden coordination means a coordinated approach whereby, when a player breaks through an opponent and meets the defensive guard or co-defense, the ball is handed over to the best-off partner at the time of the attack in a timely manner. When the other party uses a man-to-man defence or area-to-area joint defence, the other party's overall defensive deployment can be disrupted, the defensive zone compressed, and the partner can be given the best outer-field or under-basket attack opportunity of 29 answers: it is an attack type of volleyball, in which two second-hand, four attackers (two primary and two secondary) are placed in a symmetric position. 30 a: side demonstration: body side action for practitioners. It is generally used to display actions in the front and back direction, such as kicks, abdominal exercise, etc., so as to allow for a clear view of the back and forth movement. Back-to-back demonstrations: back-to-back exercises in the same direction. It is generally used in direction, route and to complement more complex operations, which enable practitioners to follow suit. The content of the textbooks alone does not meet the needs of the students and, by supplementing it, it is perfected. The response of the educational revolution is a combination of hands and minds, with the result that the power of the hands and the brain can be incredible.
