A New Tennis Practice Device Utilizing Waste Balls

technical field

The invention belongs to the technical field of tennis teaching and training auxiliary equipment, and in particular relates to a new tennis training device using waste balls.

Background technique

Only a few related tennis practice equipment can be found on the market at present, but few of them are really suitable for teaching and training, because the fundamental function of teaching equipment is to make the teaching content intuitive, the fuzzy feeling clear, the practice method simple, and the dynamic situation Immobilization etc. Ultimately achieve the purpose of effectively improving the learning effect. Therefore, the teaching equipment developed must first be highly related to the learning content, and secondly, it should be convenient for students to understand the movements intuitively. However, there are very few exercise equipments that really integrate multiple functions in the market. Tennis technology is a very technical ball game. In teaching and training, how does the teacher help the students or how does the coach help the trainees to grasp the essentials of the movements as soon as possible and understand the way of exerting force in the movements? important link. Tennis techniques mainly include serve, forehand and backhand slashing, forehand and backhand slicing, forehand and backhand volley, high pressure, lob, and drop. Only by standardizing and mastering these basic techniques can we better use various techniques and tactics in the game. The mastery of these techniques almost all involves the core link of hitting the ball with the racket and how to hit the ball with the racket. Beginners or practitioners who have reached a certain level of skill experience different ways of exerting force. The higher the level, the higher the clarity of comprehension. Therefore, teachers or coaches often use various methods in the process of helping students and athletes to understand the movements early and master the movements proficiently. Among them, the method of explaining and demonstrating is a very classic and conventional method. Due to the limitations of language comprehension ability and teacher's demonstration that cannot be randomly fixed in the air, it is difficult for students or athletes to grasp the forceful way of movements. Therefore, the decomposition method, the complete method, and the video teaching method are often adopted. Good results can also be achieved. But in practice, if the teacher can use an intuitive teaching aid anytime and anywhere to help students comprehend the essentials of movements and improve the teaching effect, it will be a very popular product. And there is almost no such relevant teaching auxiliary equipment on the market at present, and several existing exercisers are only suitable for practitioners to repeat, and it is not suitable for teachers and coaches to help practitioners intuitively learn actions and improve wrong actions.

In summary, the existing problems in the prior art are: there are almost no relevant teaching aids on the market at present. Although the existing exercisers are suitable for repeated practice by practitioners with a certain tennis skill base (prone to errors in the practice, or core movements Links such as the rotation of the ball are not clear, etc.), but for beginners or practitioners who have wrong movements, how to intuitively experience the upspin and downspin of the ball when hitting the ball, and the non-spin of the flat hit. The experience of the core link is not clear, and a device is needed to solidify the spatial position of the ball, and can clearly understand the rotation state of the ball when hitting the topspin, chipping or volleying the backspin, and flat hitting the ball. Provide more intuitive help for teachers and coaches to help practitioners learn and improve motor skills.
