Speed strength is the comprehensive expression of speed and strength, and its improvement is restricted by speed quality and strength quality. Strength and speed are the development factors that determine the rapid ability. The typical performance of speed strength is explosive force, starting force and reaction force. The improvement of explosive power depends on the development of maximum strength, and rapid exertion and super-length exercise are effective methods to develop explosive power. The improvement of motivation is closely related to the maximum strength. The use of special exercises has a positive effect on the development of motivation. The management of many clubs has made great progress, but there is still much room for development. We investigated all aspects of the club's risk assessment process. The results of the club risk assessment and management survey in 2003 showed that the following percentage of risk assessment (%) was carried out. All football clubs in England have assessed the nature and extent of club risks. 747. Attention to the possibility of risks and specific operations. Special risk research and impact assessment. Control property losses and fraud and take measures. 0045. Does the board of directors have a three-year business plan? There are two notable features in the above table. (1) In the survey, 29% of English listed football clubs are not interested in clubs. (2) The performance of listed clubs in England is quite different from that of all clubs. Only 47% of the latter have determined the nature and degree of the risks they face, only 465,438+0% have made risk possibility assessment, and only 26% have made special risk assessment. All listed football clubs in England supervise property losses and fraud and take measures, but across all football clubs in England, only 45% of clubs pay attention to this aspect, and the situation of making business plans is similar. 86% of English listed football clubs agreed to the three-year business plan of the board of directors, but compared with 48% of the latter. The survey results of risk management and business plan show that, on the whole, most English football clubs did not conduct risk assessment and business plan in time to deal with the risks they faced, nor did they make corresponding plans. In order to solve the above problems, we advocate the enterprise management mode of professional football. The model tailored for the football industry will help the club optimize its management structure and process, which will certainly improve its corporate benefits. This management mode should be relatively easy to design and low in implementation cost. The main beneficiaries of the enterprise management mode of professional football clubs will be the club itself, as well as suppliers and shareholders. The Football Association is currently designing this model: it may not reduce risks, but it will certainly improve risk management. Warm-up training From the example of football players' speed training, 65438+ Divide the players into groups of three, and assign a court to each group 15 15. Each group has 1 ball, and the players pass the ball to each other during running. After the player gets the ball, hold it for a while and don't pass it directly. Exercise 2? The training content is similar to exercise 1, except that the player makes a high jump and a leg-bending prance after each pass. Exercise 3? After each pass, run in the passing direction for a while, then run in the opposite direction. Exercise 4? Exercise is similar to Exercise 3, except that after running in the opposite direction, you continue to pay attention to your ball control partner. Let the ball move. Pass the ball flat. At the beginning of training, the speed was slow, and then it kept increasing. Pass the ball left and right. Arrange stretching and strength exercises between two exercises, or pass the ball directly in a narrow area for positive recovery. Warm-up training 24 groups? Divide the contestants into groups of 3 people, and each group is assigned a venue of 15× 15. Each group of balls. Pass the first exercise 1 exercise 2 1 1. Exercise 3 Exercise 4 Exercise 1? Specifies the number of touches before passing the ball. Two-touch and direct transmission alternate. Exercise 2? Only direct transmission is allowed. Do two exercises at the fastest speed, each lasting more than 30 minutes. Exercise 3? A player ran to the player with the ball and asked for a pass. Another player then moves. The player who wants the ball moves the ball between his feet and then passes it to the runner, who carries the ball along the running direction. Exercise 4? The practice process is similar to exercise 3, except that the first player who passes the ball finally gets the ball. Practice skills? Let the ball move. Pass the ball flat. At the beginning of training, the speed was slow, and then it kept increasing. Pass the ball left and right. Arrange stretching and strength exercises between two exercises, or pass the ball directly in a narrow area for positive recovery. Organization of the main part of the exercise 1 Divide the same exercise into two halves? Extend the sideline of the restricted area to the center line, divide the practice into three areas, and set the goal and goalkeeper. Divide the players into two groups (offensive players and defensive players) and assign them to different areas. Set up a midfield near the middle circle. Practice process? The goalkeeper throws the ball to the attacking players in a certain area. The attacker who gets the ball should try to get the ball deep in the confrontation and seek the opportunity to shoot. If the defender gets the ball, pass it to the player standing in the middle circle. In the new round of practice, the goalkeeper passes the ball to the next attacker, and so on. Athletes near the center line join the 1 to 1 confrontation and become two pairs 1 confrontation. In the periphery 1 confrontation 1, the sideline crossing strategy can be adopted to let the athletes in the central area continue to take the ball deep into the restricted area. Add 1 offensive player and 1 defensive player respectively to form a 2-to-2 confrontation. Practice skills? Put the athletes in a specific position. The goalkeeper deliberately creates a deviation before and after pitching, so that the athletes can make appropriate adjustments when receiving the pass. In the confrontation between 1 and 1, the attacking player should try his best to get the ball deep and break through, and don't take the ball sideways to avoid the defending player. Require athletes to seek opportunities as soon as possible. If it is a peripheral attack, the attacking player should look up for his teammates before passing the ball and consciously complete the sideline cross. Exercise 2 Organization of exercises? The arrangement of the venue and personnel is similar to the last exercise 1, except that the athletes in the middle circle acted as passers this time. What is the practice process? The practice process is similar to the last practice, except that the player who played 1 yes 1 caught the ball from the player in the middle circle. The attacker suddenly made a feint to move towards the goal, then suddenly stopped and asked the player in the middle lap to pass the ball. If the defender does not move in the opposite direction, the player in the middle circle can also pass the ball in the direction of the No.2 ball/baseline. The passer in the middle circle also participated in it, forming two pairs 1 confrontation. Other offensive and defensive players also participated, forming a 3-to-2 or 4-to-3 confrontation. Practice skills? Put the athletes in a specific position. 1 In the confrontation, the attacking player should try his best to get the ball deep, don't take the ball sideways and avoid the defending player. Even if there are more offensive players than defensive players in the restricted area, the offensive players should try not to cross, but try to shoot as soon as possible. The arrangement of the venue and personnel is similar to the main part of the training, except that two people are a group, and each group has a ball. What is the practice process? The player farther from the goal passes the ball to the attacking player. The attacker pretended to run in the direction of the goal, and then suddenly stopped to ask for a pass. After getting the pass, the attacker quickly took the ball to the goal and sought the opportunity to shoot. The passer immediately followed, trying to stop the attacker from shooting. After a round of practice, the two athletes exchanged roles. Practice? Defenders should keep up with the attackers and put pressure on them. Athletes are required to shoot at a distance of about 2 meters from the goal.
