Description

The shot put training aids

Technical field

The utility model relates to a kind of shot teaching and training device, particularly a kind of shot put training aids.

Background technology

Shot is a kind of traditional track and field sports items, and it not only requires sportsman itself to have stature height, strength is big, explosive force is strong good fitness, also requires it to possess technological literacy quite really up to the mark simultaneously.Becoming better and approaching perfection day by day of shot technical movements is not what accomplish in one move, needs ground warp incremental, on a firm footing to cross that long sentific training gets, the time that needs sometimes even also surplus in the of ten year.As a people who begins to learn shot put, the grasp of basis action and basic fundamental is very crucial, be after the performance of potential and the foundation stone of achievement raising.

Situation analysis with regard to current Physical Education Teaching and the training of general body, the time of beginner's training study is quite short, even in less than 1 year, just reach certain requirement or in tens class hours, grasp certain technology, this just requires in the process of professor's action, the effective training method and the means of necessary secondary row just can produce a desired effect.The inventor examines and working practice by the general height of being with of more than ten years, and continuous exploratory development, develops a kind of simple, practical, cheap shot put training aids finally.

Summary of the invention

The utility model in the existing shot training to the training of skill and grasp relatively more difficult problem, but a kind of shot put training aids of standard trainer's shot put skill simple in structure is provided.

For reaching above-mentioned purpose, the utility model has adopted following technical scheme:

A kind of shot put training aids is made up of fixed bar, support, pin, sleeve pipe and carriage release lever; The fixed bar lower end fixes on the ground; Support is in fixed bar is inserted on fixed bar top; Pin inserts the pin-and-hole on fixed bar and the support in proper order, and support and fixed bar are fixed together; Sleeve pipe is fixed on the support, and is 38 ° of-42 ° of angles between support, is provided with projection in the sleeve pipe; Carriage release lever vertically is provided with the long through groove that can be buckled on the projection, and carriage release lever is sheathed in the sleeve pipe and can moves linearly along sleeve pipe, and carriage release lever upper end end socket diameter is greater than casing diameter, and a lever is fixed in the lower end.

The utility model can also adopt following technical scheme further to realize:

Described shot put training aids, wherein, on the end socket of described carriage release lever upper end and sleeve pipe top all is fixed with 5-6 along the circumferential direction equally distributed ring, and ring links together by elastic component and sleeve pipe top ring on the end socket of carriage release lever upper end.Described elastic component is spring, rubber band or rubber bar.

Described shot put training aids wherein, vertically is evenly distributed with 3-4 pin-and-hole on the described fixed bar, the pin-and-hole spacing is 100-150mm.

Described shot put training aids wherein, is fixed with reinforced pole between described support and the sleeve pipe.

Described shot put training aids, wherein, described support and carriage release lever length are 2m, and described fixed bar length is 1.5m, and aerial part is 1m, and described casing length is 0.7m, support is welded on 1/3 place, sleeve pipe top.

Shot put training aids of the present utility model in use, transfers to proper height to training aids, team member's bipod staggered lunging position is slightly than shoulder breadth, and tiptoe is all towards oblique the place ahead, and the center of gravity of falling behind the upper body drops on the right leg, the little receipts of left arm, appropriateness is nervous, stretches to direction of bowl, the right arm recession is lower than left side shoulder, and the shoulder hip tightens, then kick one's legs and send hip, square one's shoulders and change shoulder, semi-girder driving handle to health, shoulder, arm fully stretches, then do not loose one's grip, meet, so repeat to original state.The beginner can push away from the front and carry out the transition to the front and turn and then push away to the side, and is incremental, and suitably increases and decreases the bar number of spring according to team member's actual conditions.Thereby the team member can grasp correct shot put sell hand-type, angle of trajectory, enhancing upper limbs force, and the sense of motion of the parts of body can know from experience shot put simultaneously the time, thereby reaches shot the have an effect perception of order, rational organic unity.

Step on right leg when 1, having an effect earlier, strength from bottom to top passes.

2, draw back chest and shoulder during anti-the bow, feel that pectoralis major is elongated.

3, when right arm pushes away, right leg is pedaled and is stretched, and the left side braking makes the right side action that tangible antagonism sense be arranged.

It is one group that general practitioner pushes away 10 times, connects shot 3-5 time of throwing 4 kilograms of following weight, practises 10 groups per class hour, in the process that repeats to practise, has both strengthened strength, has grasped the hand-type of selling of shot put, grasped again shot put firmly in proper order and angle of trajectory.Use this shot put training aids to carry out the shot put training during stage of begining to learn and winter training, weekly 1-2 class hour, 4-5 interval tranining phase just can be obtained very good effect.

Shot put training aids of the present utility model is cheap, simple and practical, is convenient to operation, can make the team member grasp have an effect order, the hand-type of selling, the angle of trajectory of shot put quickly.Be better than allowing the team member push away quiet and motionless object, simultaneously, also can be according to team member's actual conditions, doing the front earlier pushes away, do the front again and turn and push away, and then do the side and push away, team member's strength also obtains raising by a relatively large margin, can better know from experience route, direction, the amplitude of shot motion, thereby receive good effect.
