When street basketball and three-person basketball first became popular in China, many people confused them. Although they are all basketball sports, they are different in form and style and cannot be equated. By consulting the relevant literature, I found that many literature also confuse the two without distinction. On the basis of these documents, combined with the relevant information found on the website, this paper analyzes and compares the definition, origin, characteristics, cultural representation and functional influence. And put forward the corresponding development countermeasures. The purpose is to make people have a clear understanding of street basketball and three-person basketball, so as to embark on their own development path. 1 Definition of street basketball and three-person basketball Although street basketball and basketball are both basketball sports, they are different in nature, so their definitions are different. 1. 1 The definition of street basketball, also known as "streetball", is a new basketball form with entertainment as its main purpose and integrating fitness, leisure and performance. It is a kind of basketball, which originated in the slums of the United States and is often played by black teenagers. Because the sports ground is in a simple street or roadside basketball court, it is named. At the same time, street basketball is also regarded as an extension and a part of traditional basketball. Street basketball is not only a form of basketball, but also a branch of "hip-hop" culture, which makes street basketball a popular mainstream culture among teenagers today. However, there is a considerable difference between street basketball and traditional basketball, which makes the sport present unique characteristics on the road of development. Street basketball is rich in content, including street games, bullfighting, fancy basketball performances, street ball music and so on. There are various forms, such as one-on-one, two-on-two, three-on-three confrontation with equal numbers, and many-on-less or less-on-many confrontation with unequal numbers; The rules are simple. Since it is for the purpose of entertainment and has unique style characteristics, participants can make corresponding rules according to their own actual situation. 1.2 definition of three-person basketball, three-person basketball is a three-to-three confrontation at half-court, and it is a new sport developed on the basis of five-person basketball. From the literal understanding of three-person basketball, we can see that the number of people has been stipulated in the game or confrontation, that is, three against three, so it is not as casual as street basketball. In addition, there are clear rules of the game, so it can be considered that three-person basketball is actually similar to the traditional five-person basketball game. The origin of street basketball and three-person basketball The United States is considered as the birthplace of street basketball. The 1950s was the embryonic stage of the development of American street basketball, which was half a century later than the invention of basketball. In the 1960s, street basketball heroes came forth in large numbers, during which many streetball masters were born. By the 1970s, street basketball had occupied a place in street culture, and it was becoming mature, which also indicated that street basketball was separated from traditional basketball and became a part of street culture. Street basketball was a very vague concept at that time. As long as a basketball game or game appears on the roadside or in the park, it is called street basketball, and there is no specific meaning to interpret street basketball. So those roadside and street corner three-person basketball are also within the scope of street basketball. The author thinks that the embryonic form of street basketball should be three-person basketball. Why do you say that? In the 1950s, streetball was still in its infancy, and the technical level of streetball at that time was far worse than today. It is conceivable that the streetball technique at that time can be said to be the basketball technique commonly used by athletes in traditional basketball, but it was not the real streetball technique. 3. 1 Through the investigation and analysis of basketball injuries of basketball fans at three levels, it is found that the incidence of basketball injuries among basketball fans at three levels is higher. Extracurricular exercise is the main period of injury, accounting for 365,438+0.3%, and the injured parts are hand, ankle, knee, waist and thigh in turn. The common types of injuries are sprain, strain, abrasion, dislocation and fracture. The reasons are insufficient warm-up activities, insufficient self-protection, improper exercise methods and venue factors, resulting in sports injuries. 3.2 The key to make full preparations for preventing sports injuries lies in physical education teachers. Therefore, it is necessary to improve the safety awareness of physical education teachers, make full use of various forms to make students master reasonable methods of warm-up activities, guide students to make full preparations, and cultivate students' good habits of doing warm-up activities before sports. Whether in class or after class, we should make full preparations for the activities. The content and exercise load of warm-up activities should be determined by time, venue, climate and other factors according to the teaching content or competition situation of this class, and attention should be paid to the characteristics of students' specific situations, especially ankle joints.
Knee and wrist movements. The amount of exercise depends on the students' specific conditions and climatic conditions, with fever and slight sweating as the best. 3.2 Strong sense of self-protection, it is very important to strengthen the self-protection awareness of basketball fans. We should have a certain awareness of injury prevention, besides preparing for every basketball activity, we should also dress for sports, choose high-quality basketball shoes, check whether the shoelaces are fastened, use protective devices to protect vulnerable parts such as ankles and knees, control the waist and abdomen in the air when rebounding, support the feet to land smoothly, make a habit of running and making a layup, and roll to buffer and break the ball actively or after being hit. 3.2 The site should be regular, with strengthened management and timely maintenance. In the process of website construction, we should strictly follow the national website construction standards and ensure the quality. Establish a reasonable and scientific management and maintenance system. Strengthen the investment in sports venues and equipment, maintain venues, purchase equipment, equip with protective gear, check regularly and maintain them in time. Before the exercise, it is necessary to clean up the debris on the site, pay special attention to the unevenness of the site, and minimize the damage caused by the equipment on the site. 3.2 Correcting the wrong movements in sports in time violates the structural and functional characteristics of human body and the mechanics principle of sports, and easily causes sports injuries, which are more prominent in basketball. Especially the wrong technical action. Teachers should not only teach correct technical movements, but also correct students' irregular movements or wrong movements in time, which is also the key to prevent sports injuries. This not only requires teachers' patient guidance in the usual teaching, so that students can form a correct concept of action, but also be good at analyzing the causes of these irregular or wrong actions and correcting them in time. When students engage in basketball after class, they find their wrong actions or feel that their actions are wrong, clumsy and uncoordinated. You can ask experienced students with correct basketball skills to analyze the causes of wrong movements and help them correct them. In short, correct the wrong actions in time to avoid injury accidents. 3.2 Other aspects of prevention The causes of basketball injuries include other reasons besides the above four reasons, such as poor physical and psychological state; Excessive exercise load; Improper organization method, bad weather and physical quality. In basketball, we can't ignore the prevention of these aspects. In addition, there should be some time to relax or massage after training or competition to eliminate physical fatigue and prevent damage caused by fatigue accumulation. Second, talk about the basketball referee's viewpoint: talk about the basketball referee's viewpoint: 1. The establishment of "ball sense" is a special perception developed in training and an important psychological skill of basketball referees. It enables referees to analyze the shape, weight, elasticity, spatial changes of the ball, the running speed of the ball, the movement state of the ball control players and the passing direction in detail. In order to eliminate the illusion of visual judgment and make accurate judgment, therefore, in basketball referee training, referees are required to practice throwing, running and following the ball to increase the "ball sense", so that referees can freely judge the movement direction, spatial state and development direction of the ball in the game and play the best referee level. Just like in the game, there is almost no fixed concrete form of action and cooperation after the ball jump in the middle circle, and even the new situation that appears in the game may not have appeared in the referee training. Under special circumstances, freedom and flexibility can be found, which is closely related to the basketball referee's mastery of "ball sense". Therefore, the basketball referee's "sense of the ball" is an important psychological skill for the referee's technical level to achieve high-level development and emergence. It can not only make the action flexible, but also be an important psychological factor to obtain superb referee skills. 2 ".attention" concentration practice concentration is the ability to persist in focusing on a certain goal without being distracted by other internal and external stimuli. In the face of the game, the referee can't watch the wonderful technical and tactical cooperation of the game be disturbed like the audience, but should keep a clear head, straighten his position, enforce the law actively, fairly and accurately, and ensure the smooth progress of the game. Therefore, in the psychological quality training of referees, we should pay attention to concentrated training. Paying attention to quality is the psychological quality that basketball referees must pay attention to. In the referee work, accurate, rapid and effective referee can not be separated from high attention. The cultivation of referees' attention skills is mainly in skill training and formal competition, and consciously distinguishes the levels and goals of attention. For example, in terms of fouls and violations, we should pay attention to fouls. In terms of fouls, we should focus on personal fouls at the basket and fouls against shooters. Then shift the target, focusing on the foul in the offensive and defensive confrontation with the ball area and the foul of the players without the ball. Finally, turn your attention to the foul penalty.
Let's go This hierarchical, focused and targeted attention skill can train the referee's attention selectivity, directionality and orderly distribution ability. Making the referee's attention clear and focused, and paying attention to reasonable allocation and transfer opportunity can overcome the bad psychology of "you can't catch anything if you want to", thus improving the psychological quality of the referee. 3 Paying attention to imagery training Imagery training is the most commonly used psychological training method in the field of sports. Imagery training is conducive to establishing and consolidating the correct dynamic stereotype of action, accelerating the proficiency of action and deepening the memory of action. In the basketball referee's work, the referee's gestures and the corresponding speed and accuracy are an important aspect to reflect the referee's level. The quality of the referee's gesture has obvious influence on the athletes. Timely and standardized gestures can establish the prestige of the referee, so the referee's actions are an important part of the referee's work. In the basketball referee's action training, the referee always makes gestures and actions according to the mental representation, so that the referee can make actions as accurately as possible and form a good action representation.
