Description
Technical field
The present invention relates to sports apparatus technical field, refer to a kind of vollyball force exerciser especially.
Background technology
In volleyball movement, slam-shot is one of basic fundamental, is also aggressiveness the most effective the strongest offensive means, occupies very important status in play.Drop shot technique comprises first position, run-up, take-off, bats and land in the air.Wherein aerial shot is the key link in drop shot technique movement structure.Volleyballer has aloft batted spiking after the braking take-off of run-up, and keep the rational position relation of good body and ball, give full play to the coordination strength of whole body, this just requires reinforced platoon ball sportsman core space stability training.
It is 201410297914.9 that Chinese patent discloses application number, name is called the patent of invention of vollyball force exerciser, be made up of pulling force rope, arm, handle, pulling force rope fixture and arm fixed mount, one end of pulling force rope is fixed on the bottom of volleyball frame column by pulling force rope fixture, the other end of pulling force rope is fixed on the pulley at arm top, arm is fixed by arm fixed mount, arm fixed mount can regulate the height of arm, pulley is arranged at the bottom of arm fixed mount, and arm fixed mount is fixed on volleyball frame column top by bolt and latch.The direction of arm is contrary with the direction of volleyball net, and the effect of arm has two, and one is the height regulating pulling force rope handle place pulley, and another effect is to bypass the ballast box of volleyball frame, is convenient to train.The service of vollyball original place, jump service and the strength of jump smash and the training of technical movements can be carried out by this training aids.Training aids is provided with the pulling force rope that two strength is different, can according to the strength needing selection different of training.
Technique scheme, although carry out the strength building of arm by holding handle, actual square stance, the five fingers part a little in spoon shape, and keep suitable anxiety, encase ball with full palm, the centre of the palm is center ball strike, and arm fully stretches, the rear middle and upper part of batting or rear middle part, wrist with sudden force rapidly under get rid of, urged forward of simultaneously initiatively counting on one's fingers, the training method of this strength may affect the quality of batting.In addition, when training take-off batting or service, must takeoff, the handle be aloft connected with pulling force rope that takeoffs can have a reaction force to arm, easily lose center of gravity aloft and fall down, and the fixed mount in this technical scheme fixes on the ground, easily encounter fixed mount if accidentally fallen down during training, there is certain potential safety hazard.
Simultaneously the material poor toughness that adopts of existing vollyball force exerciser, is easy in use fracture, occurs the situations such as slight crack, and do not possess anti-flammability, poor heat stability.
