Technical Field

The invention relates to the technical field of volleyball training instruments, in particular to an adjustable matched volleyball discharging device for volleyball training.

Background

Volleyball, one of the ball sports projects, the ball field rectangle, the middle separates there is high net, six persons of both sides of match each take one side of the ball field respectively, the player uses the handle ball to beat from the net in the sky, the ball that volleyball sports uses, use sheepskin or artificial leather to make the shell, the bladder is made of rubber, the size is similar to football, the rule of volleyball is, six players of each side serve the ball according to the clockwise direction in turn, after each time the team obtains the right of serve, the player sends the ball into the other half of the side in the right relief angle of the side to restart the match, the player can serve the ball with the upper hand or the lower hand, can use the fist, the five fingers or the arm that is stretched out to come out, the play can be in any place behind the base line, but the rules again allow the player who is jumping to the ball to enter the field when it falls, the volleyball can fall anywhere in the other half, and the player will continue to serve until the team loses the right to serve.

The bouncing of volleyball sports can exercise leg muscles and hip muscles well, and people with poor balance ability can also improve the posture of the people by playing volleyballs; frequent running and jumping contribute to hematopoiesis of the spleen; the volleyball is relaxed but not particularly violent, so that the physical exercise is performed, excessive exercise is avoided, and a proper amount of aerobic exercise can supplement kidney yang and keep vitality; the catching action in the volleyball hitting action is always to beat and stimulate the three yang channels and the three yin channels in the arms, when volleyball is hit, not only the peripheral nerves of fingers stimulate the movement, but also the whole limb movement in the volleyball movement process further drives the human body to stimulate the muscle coordination of the whole body from head to foot, and the whole body can move uniformly everywhere; the volleyball can make the nervous system more flexible, such as mental inattention, mental asthenia, etc. can also receive unexpected regulating effect; the ball playing can not only exercise the body, but also improve the psychological quality of people, and the good psychological quality can be flexibly reflected agilely in the competition field.

Volleyball belongs to aerobic exercise, can not only exercise the explosive force and the bounce of people, but also improve the endurance and is beneficial to the growth of muscles; the basic actions of playing volleyball are that the squat and head raising are prepared like leopard, the actions of catching, running, catching and defending are extended, the actions of playing the five birds are basically included, the development of the spine is better, the spine can be self-repaired by frequently playing volleyball under the condition that the spine of the middle-aged people is easy to deform, the compression on heart and lung muscles is relieved, and the cardio-pulmonary function is improved.

The cushion ball is the basic action in volleyball sports, the cushion ball technology is divided into front cushion ball, side cushion ball, back cushion ball, block ball, tumbling cushion ball, front-flapping cushion ball, side-falling cushion ball, fish-jumping cushion ball and the like, when the coming ball is far away from the body and is not as far as the cushion ball with two hands, the cushion ball with one arm can be used, the front cushion ball is the basis of all cushion ball actions, so the user should firstly learn and play the basis, then practice the technical actions of the side cushion ball, the direction-changing cushion ball and the like, the dependence of the service ball and the fastening ball on the basic cushion ball actions is strong, and the service ball and the fastening ball are only practiced after the basic action is mastered.

Along with the improvement of the technology, more and more volleyball training auxiliary devices appear, because a lot of technical actions need to hit the ball that is thrown from opposite direction, serve or play the ball device and be indispensable in volleyball training, current play ball device play ball angle is single, can not adapt to various volleyball training plans to the dress ball volume is few, and it is inconvenient to remove, has influenced the promotion of training effect.
