Technical field
The utility model relates to the servicing unit that a kind of high jumper (student) carries out approach by a circular path take-off form work, is specifically related to a kind of fosubry flop arc flying jump exercising machine.
Background technology
Flying jump is the emphasis and the difficult point of Teaching of Back Style High Jump.At present, dual mode is adopted in the exercise of fosubry flop arc flying jump usually: the one, draw camber line on the ground, and let the student along approach by a circular path; The 2nd, adopt traditional take-off board take-off.When adopting aforesaid way to decompose exercise (simple approach by a circular path or simple beat board take-off), the student all can carry out on request.In case combine both, students' union occur health lift too early (introversion is not enough), large profound step, straight line run-up, recumbency take-off, towards pole, fall problem such as pole too early.Adopt traditional exercise mode, be difficult to fast, in time, deal with problems exactly, in a single day flying jump is done well, and that is follow-up crosses bar action and also certainly will be difficult to accomplish.If things go on like this, must influence teaching process and teaching efficiency.
Summary of the invention
The purpose of the utility model is for overcoming the deficiency of above-mentioned prior art, a kind of fosubry flop arc flying jump exercising machine being provided
For realizing above-mentioned purpose, the utility model adopts following technical proposals:
A kind of fosubry flop arc flying jump exercising machine, it comprises the runway that is provided with along fosubry flop run-up route, the runway face of this runway is the outside and is higher than inboard inclined plane.
The main purpose of approach by a circular path is to obtain higher run-up speed and bigger centrifugal force health is crossed the bar, and the introversion that this just requires in the run-up process, to strengthen health forms the body gesture of right shoulder height in left side shoulder (left leg take-off is an example).In conventional teaching, like no servicing unit (especially in the stage of begining to learn), the student often takes the straight line run-up at the back segment (especially two steps of back) of camber line for accelerating take-off speed, thereby has influenced take-off and crossed pole.Adopt " outside is higher than inboard inclined plane ", can " force " student to form the posture of right shoulder height naturally, and accomplish follow-up action with this posture in left side shoulder.
The front end of said runway is a ski-jump, and the runway face at this ski-jump place is the plane.The nature take-off is more approached on the plane of comparing with the inclined-plane of traditional take-off board, and is difficult for causing the student to the back upper place take-off, thereby forms the malfunction that recumbency is crossed pole.
Said runway comprises the base of arc, and base is provided with plank, and the plank surface coverage has plastic pad.Plank and plastic pad play cushioning effect, avoid the wound to lower limb.
Said inclined plane is increased to jumping its gradient of point more by starting line gradually.The angle of inclination of this exercising machine is ascending, has promptly similarly run a little upward slope.Said runway face comprises straightway and arc, and its radius is 6-8m, and length (arc length) is 1/4 circular arc.Its advantage is: one helps the natural transition of straight line run-up to approach by a circular path, keeps the rhythm and the stability of run-up; Two introversions that help keeping health are with the quickening of speed-adaptive and the increase of centrifugal force, thereby accomplish take-off with rational posture.Exercising method: the sportsman accomplishes flying jump action (can cross bar or only bar) on this exercising machine.
The beneficial effect of the utility model is, is suitable for various levels of high jumper (student), has remarkable effect for improving and improving approach by a circular path take-off technology (especially last two steps).This auxiliary apparatus can let the sportsman in the exercise process all the time along approach by a circular path; In the maximum introversion of health, accomplish the take-off action; Obtain higher rise height and bigger centrifugal force,, and cross the bar rapidly so that health has adequate time and space to accomplish back of the body bow.Can improve arc flying jump technology effectively through repeating, and then obtain time enough and space and accomplish the follow-up bar action of crossing, form good muscular exertion and feel.Can shorten school hour, improve efficiency of teaching.
