(A) the technical and tactical appreciation of sports competitions
In sports competition, technology is the basis of completing tactical coordination, and the continuous evolution and development of tactics put forward higher requirements for technology. In order to give full play to the physical quality and skills of individual athletes and sports teams and achieve excellent sports results, sports competitions show a high degree of skill. The audience is interested in the superb skills and tactics of athletes and sports teams.
In ball games, basketball, volleyball, table tennis, football, tennis, badminton and other sports are developing very fast, and new technologies are constantly emerging. For example, jump shot, hook shot, make-up shot, one-handed, two-handed dunk, and three-pointers in basketball games. We can also appreciate passing, dribbling, rebounding and other techniques and defensive skills. The unpredictable technical movements of American professional athletes are amazing.
When enjoying the football match, we especially like the wonderful scenes. Football shooting is the end-result of attack, but whether the goal of shooting can be achieved depends on how athletes use basic skills such as passing, ball control and passing. The higher the quality, the more shots, and the greater the possibility of winning. 12 World Cup, Italian star Rossi quickly broke through the middle and scored a goal. The whole process is done in one go, fast and not chaotic. 13 World Cup, Argentine Diego Diego Maradona got rid of his opponent, dribbled quickly, dodged four opponents' tackles and scored a goal. An excellent player shoots balls with different heights and different routes with his feet and head. Brazil's Nellino and Peru's Gubis used the instep to shoot an arc with strong rotating force, which could bypass the human wall and fly to the goal, showing superb skills.
In addition to the common basic skills such as moving, passing, serving, spiking and blocking. Fast ball technology has developed rapidly. The more common ones are near-body fastball, short-flat fastball and far-net fastball. China volleyball players also created and developed fast ball techniques such as "time difference" and "position difference", which played a role in self-protection and getting rid of fast break, and were called "stars of hope". Japanese star Guangjijiang has the stunt of sliding backwards and wiping quickly, while China's Li Yueming is witty and flexible. These superb technologies are refreshing.
Millions of tennis fans in Qian Qian are intoxicated by this tennis match. Excellent tennis players are fierce in the game, with accurate baseline shots, large angles and many round-trip balls. At the same time, they also have good serve and net-front skills. Techniques to shoot down the earth in tennis include forehand and backhand strokes, lobs, short balls and rebound balls. Interception techniques include forehand and backhand return before landing and high-pressure ball. Serve includes flat serve and rotating serve.
While enjoying the diving competition, we saw the graceful aerial movements of the athletes, and the diving movements like needles inserted into the water brought us to a perfect technical and artistic situation. In springboard diving, athletes should make rational use of the rebound force of springboard to obtain a better take-off angle and height. Therefore, walking and jumping is the basis of springboard diving technology. The whole body's pressing plate action should be consistent with the rhythm of jumping vibration.
Platform diving technique is completely different from springboard diving in run-up and take-off. It runs up at a faster speed and doesn't need a high jump. When doing arm-standing diving, the athlete walks to the front of the platform, grasps the front of the platform to keep his body vertical and keep a stable balance, and then completes various beautiful diving movements.
"Splash suppression" technology has been mastered by excellent athletes all over the world since 1970s. When an athlete enters the water, his arms are stretched out forcefully, and his palms are turned up and down at the moment when he is about to enter the water, so that his body forms an entry angle of 90o or close to 90o with the water surface. The smaller the splash, the better.
Gymnastics competition requires athletes' technical movements to be both difficult and steady, accurate and beautiful, with good rhythm and large range. We can appreciate its basic technology from the following aspects: static posture, overhang and support. Such as right-angle support, inverted cross support, etc. Forced action: there are hanging and supporting, supporting and supporting, and hanging and hanging transition. Swing movements: there are turns, somersaults, turns, grip changes, jumps and swings. When we are enjoying the gymnastics competition, when we see the athletes complete a set of movements, we often use difficult thrilling movements to leave a beautiful final picture for the audience. However, many athletes were punished for landing unsteadily.
With the improvement of gymnastics skills, there are many difficult new moves. American athlete Leiden performed belly dancing on the uneven bars, and then sat on the uneven bars and did a backflip. Sawao Kato of Japan first completed the action of hanging the front ring on the lifting ring. Since then, the loop double has developed into a big loop on the horizontal bar, and there have also been big loop movements on the parallel bars and uneven bars. On the horizontal bar, Tkachev of the Soviet Union performed the action of "holding a big loop and spreading his legs back into a suspended grip". Wu of China created "Jia Ni prance" on uneven bars, and Li Ning performed "Thomas Full Spin" on floor exercise and parallel bars for many times. A set of high-level gymnastics movements is a beautiful work of art, which is the result of careful design by coaches and hard training by athletes.
The content of Wushu competition can be divided into two categories: one is the competition in the form of routine; The second is the competition of attack and defense. The former includes Changquan, Nanquan, Tai Ji Chuan, fencing, fencing, cudgel, spear and other boxing techniques, and other equipment sparring and group events. The latter has Sanshou and Tai Chi tuishou.
Wushu is known as "correct moves and drawing circles". Static posture is generally called "posture", from moving to static, it is called "moving", moving like lightning and static like Mount Tai. All kinds of punches, palms, legs and footwork in Wushu should be completed completely, with clear routes, accurate power points and orderly attack and defense. There are many kinds of martial arts, so we should pay attention to the technical characteristics when appreciating boxing matches. The movements should be correct in posture, clear in power point, coordinated inside and outside the body to form a whole, and the inner consciousness of one stroke and one style should be fully expressed through the eyes, fast and slow, dynamic and static, rigid and soft, and the rhythm of ups and downs is clear. The northern school is characterized by its large posture, stretching movements and wide range of activities. Nanpai is characterized by small posture, compact movements and small range of activities. Tai Ji Chuan is soothing and soft, brisk and lively, like flowing water, continuous; Bagua palm is full of vigor and vitality, and the situation is constant; Xingyiquan is simple and vigorous; Tongbei fist is long and powerful; Boxing inspection is compact and rhythmic.
Knife is brave, fast, aggressive and strong. "Look at your hand with one knife and look elsewhere with two knives." Single-pole requires athletes to be quick-eyed and quick-handed, and their advance, retreat, flash and vertical jump should be changed with them, and their hands should be coordinated. Double knives should be coordinated from left to right, with flexible steps, priorities and priorities. The broadsword should be magnificent and powerful.
Shooting mainly focuses on stopping, taking and stabbing. The gun should be straight and fast, straight out and straight in, straight to the tip of the gun, so that the gun can be tied in a line. The gun comes out like a hidden dragon, and the gun enters the hole like a tiger. There are three kinds of spears: the upper level, the middle level and the lower level. The gun-blocking method is to block defense. The marksmanship is flexible and changeable, and the footwork is light, fast and steady.
Fencing is characterized by lightness, agility, chic and elegance. The "single sword" sword technique is changeable, the action is in one go, the momentum is coherent, the sword and god are one, and the waist is like a snake. "Double Sword" is vigorous and powerful, full of strength, and the sword body is integrated. The "long thorn sword" moves with the steps, the sword moves with you, the thorn dances with the sword, and it is natural and unrestrained.
"The gun sticks a line, and the stick hits a large area." The stick method has a wide range of activities, and the hands, eyes, body, method and steps are coordinated. The dance stick is brave and fast, and the body and stick are integrated, and the force penetrates the tip of the stick.
All sports are composed of a series of technical movements. Each project has its own technical characteristics. When appreciating physical education graduation, we should not only pay attention to the athletes' completion of technical movements, but also appreciate how athletes use their own favorable conditions to form unique technical characteristics.
Tactics in sports competition refers to the art of competition in which both sides correctly distribute their strength, take reasonable actions, give play to their own advantages and limit each other's specialties according to the changes in the competition field, so as to win in the competition. It consists of tactical thoughts, tactical awareness and tactical actions, and different sports competitions have different tactical characteristics.
In track and field competitions, tactics are determined according to their own characteristics and opponents' situation. Such as physical distribution, speed arrangement, follow-up, final sprint and so on. Jumping high school is to save physical strength, give psychological pressure to opponents, avoid taking off and grasp the height of taking off. In the 24th Olympic Games, the competition for men's high jump is fierce, and the psychological war between Afdinko of the former Soviet Union and Schoenberg of Sweden, who once set a world record, is very noticeable. Experienced Schoenberg has been using jump-free tactics to deal with Afdinko, trying to make the other side nervous. Avdeenko won the Olympic gold medal in men's high jump with a score of 2.38 meters. In the 24th Olympic Marathon, Italian Bolding won the gold medal in 2 hours 10 minutes and 32 seconds with his successful tactics.
In highly antagonistic ball games, tactics are more flexible and complicated. Tactically, the first thing to be solved in a football match is the game formation. The choice of formation is mainly based on the characteristics of the team and the physical fitness and technical level of the athletes, and combined with the strength comparison between the two sides and other objective conditions (venue, climate, etc.). ) also consider. Generally, there are "3-2-2-3" formations, namely "W", "M", "3-3-4" and "3-2- 1-4", and the above formations are three defenders. The formation of four defenders is "4-2-4", "4-3-3" (including "4-2- 1-3", "4- 1-2-3") and "4-4-2". Individual tactics are the individual actions and methods taken by athletes to complete the tactical cooperation of the whole team.
The team tactics commonly used in the game are: team attack tactics, team defense tactics and set-pieces tactics. Team attack can be divided into sideline attack, middle attack, transfer attack and offside prevention tactics. The defensive tactics of the whole team generally include regional defense, tight man-to-man defense, tight man-to-man combined with regional defense and offside tactics. Set-piece tactics mainly include kick-off, penalty, corner kick, throw-in, free kick and shooting tactics. The advanced "all-football" overall play has brought football to a new realm. This tactic focused the attention to the maximum extent and mobilized the enthusiasm of the whole team. Offensive football further emphasizes and advocates attack, encourages more shots and strives for more goals. Argentina coach Merotti said: "Attack is the foundation of football, and only attack can win." Football tends to be "quick and complete" day by day. Total football's tactics will be more perfect. This football match will be more exciting.
Modern volleyball tactics are constantly changing and developing. The combination of high and fast in the past has gradually turned into high happiness (flexibility). High and fast not only refers to the combination of high hitting, strong attack and fast attack, but also refers to the combination of development height and high-point fast attack. Therefore, the control right of modern volleyball match is very important. The main tactics of volleyball match are "one pass and two passes": one pass to the third player and two passes, and the second and fourth players attack. "Side one, two": the first pass is given to the second player, and the third and fourth players attack. This is the most basic tactical form. "Twice Ball": When the passing mat reaches the smash point at the edge of the net for the first time, the players in the front row smash the ball immediately. The "two goals" tactics are hard to distinguish between true and false, which makes the opponent's block unpredictable and unpredictable, and can play the role of a sudden attack. "Backrow Insertion": After the opponent serves, a setter in the back row quickly inserts into the front row to make a second pass, so that the players at positions 2, 3 and 4 are not responsible for the second pass, thus ensuring the three-point attack in the front row. There are also blocking and defensive tactics. The content and quality of tactics are very important. Sometimes simple tactical forms can also play high-quality and changeable balls.
