Abstract
The utility model discloses a top-cambered bi-slope takeoff trainer for the teaching and training of broad jump. The utility model at least solves the following problems that: since necessary trainersfor the training of broad jump are lacked at present, athletes cannot easily master a good takeoff action, the training period is long, and the effect is not good. The takeoff trainer at least has the following advantages that: the structure is simple, use is convenient, the training period can be effectively shortened, and the takeoff trainer can help athletes to develop a good takeoff habit, sothat the athletic performance can be increased. The structure of the takeoff trainer is as follows: the athletic performance comprises a rectangular prismoid-shaped takeoff device, the top of the takeoff device is a cambered surface, two slopes are symmetrically arranged along the length direction of the takeoff device on both sides of the cambered surface, one of the slopes is a decelerating buffer surface, and the other slope is a takeoff-assisting surface.
Description
Technical field
The utility model relates to a kind of long-jump exercise equipment, relates in particular to a kind of long-jump teaching and training arc top bidirectional inclined take-off exerciser.
Background technology
Long-jump is two sports of men and women of International Track and Field Association's regulation, also is universities and colleges large, medium and small at different levels and the sports speciality main course and the event of State Education Commission, General Administration of Sport's regulation.There is certain problem in the teaching and training of this project at present, be that existing its drawback of imitation formula teaching methodology finds rational technology sensation for not making the sportsman, intuitive is poor, and speed is easy-regulating not, and amplitude is little, the flesh sense is poor, muscle group is extraordinary firmly short, and work distance is short, and acting opportunity, amplitude are difficult to grasp, cause the teaching and training cycle long, weak effect.
The utility model content
The purpose of this utility model is exactly that the step third from the bottom puts pin take-off high speed run-up just and the difficult grasp of take-off engagement technique with penultimate stride in the present long-jump campaign key technology in order to solve, cause the sportsman to be difficult for forming good take-off action, thereby cause cycle of training long, problem such as do very well, provide a kind of have simple in structure, easy to use, can effectively shorten cycle of training, help the sportsman to form good take-off custom, thereby improve the long-jump teaching and training arc top bidirectional inclined take-off exerciser of advantages such as sports achievement.
For achieving the above object, the utility model adopts following technical scheme:
A kind of long-jump teaching and training arc top bidirectional inclined take-off exerciser, it comprises rectangle terrace with edge build take-off device, take-off device top is a cambered surface, in the cambered surface both sides along take-off device length direction be symmetrically distributed two domatic one be that the deceleration buffer face is a take-off power-assisted face with another.
Take-off device bottom is provided with the air discharge duct that at least one is provided with along take-off device width.
Described deceleration buffer face and horizontal plane angle are the 3-12 degree; Take-off power-assisted face and horizontal plane angle are the 3-12 degree.
Described take-off device length is 1.5m-3.5m; Width is 0.6-1.2m; The height of take-off device is 0.18-0.3m; The action of cambered surface is 0.02-0.06m.
The length of described air discharge duct is identical with the width of take-off device; The width of air discharge duct is 0.4-0.6m; The Edge Distance 0.5-0.7m of air discharge duct and take-off device width.
Described deceleration buffer face and take-off power-assisted face and cambered surface are provided with plastic layer.
The beneficial effects of the utility model are: it has changed outmoded imitation formula teaching methodology, created the die type teaching idea scientifically and rationally, it is at long-jump major technique difficulty " run-up and take-off engagement technique ", at the degree of accuracy that exists in step third from the bottom when the long-jump and the penultimate stride, put pin, braking, take-off important technical links and designing such as soar, solved fast braking, second step of containment, accurately increase the work distance of leading leg, make muscle group sensation obviously and take-off fully wait, has the positive reinforcement teaching simultaneously, dynamic stereotype, effects such as shortening the teaching cycle improves results.Its utility model with long-jump after three step technological difficulties by in addition scientific and reasonable clearing up of the utility model, among the mould teaching and training, this instrumentation is convenient, saves, and is durable, not fragile.

Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the lateral plan of Fig. 2;
Fig. 4 is the another side view of Fig. 2.
Wherein, 1. take-off device, 2. deceleration buffer face, 3. take-off power-assisted face, 4. air discharge duct, 5. cambered surface.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.
Among Fig. 1, Fig. 2, take-off device 1 of the present utility model is the prismoid of a rectangle, a cambered surface 5 is arranged at the top of prismoid, the effect of this cambered surface 5 is to prevent that thereby the sportsman from riding deceleration buffer face 2 backs at one and sliding the problem that influences the take-off acting because habitual movement another pin mops floor, because the sportsman is in training at ordinary times, three actions will be arranged at the take-off device as last: a pin slows down with stepping on, this is the step third from the bottom, and it is for the power conversion of horizontal displacement speed is forward prepared for upwards rising power; Be another foot-operated ground take-off then, this is a penultimate stride, because the height of this step center of gravity will determine to rise the size of potential energy, if center of gravity is low excessively, will causes lifting height not enough, and influence the distance that final step is landed, and causes doing very well.Because the sportsman do not have corresponding exercise equipment at ordinary times, can only the imitative exercise of pattern, can not find a comparatively desirable leg height of lifting, thereby form a good habit.And relating to by cambered surface 5, thereby will having to behind the deceleration buffer face 2 on foot-operated another pin height lifted first, the sportsman increases the work distance that takes off leg, fall on the take-off power-assisted face 3, otherwise can't fully finish the take-off stroking technique, so just play tall forced movement person virtually, shortened the hop distance that rises of horizontal direction, help finishing of its flight part, and find of being fit to oneself to lift the pin height by repetition training, thereby form a habit, on the competition field, can determine even more ideal achievement.Take-off device 1 is respectively deceleration buffer face 2 and take-off power-assisted face 3 along its length direction in cambered surface 5 both sides, deceleration buffer face 2 will help athletic deceleration, and 3 in take-off power-assisted face helps it to grasp the dynamics of take-off.For preventing when take-off is trampled to make that because of strength is excessive forming gas-bearing formation between take-off device bottom surface and ground sends sound, be provided with two parallel air discharge ducts 4 in the bottom of take-off device 1, the gas emptying that can produce when trampling.
Occur when preventing that the sportsman from trampling the take-off device sliding, on deceleration buffer face 2, take-off power-assisted face 3 and cambered surface 5, be provided with plastic layer.
