Embodiment

In fig. 2, the two ends of column extension spring are connected on the column of both sides, and intermediate groove formula sponge pad planker is the main region of exercise, and inside grooves is manufactured with sponge protection pad to protect. Practitioner is back to the main part in figure, takeoffs and lie down in this part with stern waist position in original place, forms the back of the body bow posture faced upward head and shift a burden from one shoulder to the other and push up hip. As wrong, it is possible to help it to correct, allow practitioner have the enough time to know from experience back of the body bow action, obtain muscle force feeling, and then form correct power sizing. On this exercise basis, it is possible to be transitioned into the imitation exercise of previous step (or a few step) take-off.

Shown in composition graphs 1, Fig. 2, Fig. 3, Fig. 4, practitioner decomposes incremental exercise, and run-up step number is 8 12 steps, and front section is run straight line, and rear section runs camber line, with from the leg take-off away from cross bar. After take-off is liftoff, keeps stretching posture and upwards rise, and leading leg and under drive with side arm, accelerating health and rotate around the longitudinal axis, make health back to cross bar; Right overhead, after shoulder crosses cross bar, facing upward head in time, shift a burden from one shoulder to the other, Zhan Ti, square one's shoulders, and receive both legs after a while, form back of the body bow posture on bar, centre of body weight is as far as possible near cross bar simultaneously, to make full use of the height that soars; After centre of body weight moves past cross bar, should accelerate upwards to swing one's legs and cross cross bar. Fall to padding with back after crossing bar.

Fosubry flop technology feature: the principal feature of fosubry flop run-up is camber line run-up, run-up line is generally " J " its advantage and is: 1. the preparation section of run-up is that the line that a straight line or curvature are very little is bent, and therefore whole process is convenient to accelerate and performance speed. 2. to the relatively milder nature of camber line transit time, it is possible to avoid pausing or slowing down. 3. camber line curvature is from large to small, makes health progressively add imperial palace frequently. 4. final step about becomes 20 degree to 30 degree angles with cross bar, to ensure that human body is after soaring, has the vertical translation distance relative to cross bar that suitable.

Fosubry flop approach technique: the task of run-up obtains necessary horizontal velocity, and create condition for improving take-off technique and cross cross bar smoothly. Fosubry flop generally adopts 8 to 12 step run-ups, point straight line run-up section and camber line run-up section. 1. straight line approach technique: be similar to race technology in short circuit way, centre of body weight height when running into and steadily upper body suitably lean forward, after pedal fully strong, front pendulum actively lifts leg, and two-arm cooperation significantly swings; 2. camber line approach technique: health is introversion progressively, strengthens the swing amplitude of outer legs arm, and holding head, trunk become a straight line inwardly to incline. The whole process of run-up should have obvious accelerating ability and stronger timing, and especially last a few step is accelerated gradually, the fastest to final step.

Run-up easily violates problem in imparting knowledge to students; the curvature of fosubry flop run-up camber line is improper; in study camber line run-up; often there will be the problem that run-up camber line is incorrect, mainly there will be following several mistake: mistake 1: in run-up, health introversion is not strengthen gradually; but when entering camber line at the beginning; health introversion is maximum, runs and erects on the contrary to health during the last two steps, shows the un-reasonable phenomenon having on run-up route and running straight line. Mistake 2: in run-up, health introversion does not change, and shows the un-reasonable phenomenon having on run-up route and running circular arc. Mistake 3: in run-up, health introversion, by greatly constant, shows the un-reasonable phenomenon having in run-up and going for a stroll. Produce the reason of above-mentioned mistake: student fails to grasp the technology of camber line run-up, form correct camber line and rely on proprioception to control the change of health introversion. Check the method for mistake: check that whether the run-up step point of student and route be correct, it is possible to according to the technical requirements of camber line run-up, each step being checked, the turnover (generally claiming turning angle) that usual each step runs into direction should strengthen gradually.

Main teaching method: 1, use various radius camber line to run exercise. (1) accelerative running of straight way and upper and lower bend. (2) radius is the circle race of 6-8 rice, spiral runs and " 8 " word runs; (3) straight line connects camber line or straight line incision circle race. 2, practising teacher by apparatus utilizes long rope to connect the Faculty and Students one end of rope (student grab with inner side hand). During camber line run-up, teacher exerts oneself pulling rope to strengthen centripetal force, forces student's trunk to keep suitable introversion, strengthens the proprioception of muscle. 3, utilize mark to carry out camber line run-up exercise teacher to utilize markings or on ground, draw advance route, it is desired to student practises repeatedly along mark or route, strengthens correct camber line run-up sensation. Size block in way can with little wooden unit or sponge block, it is possible to be placed on camber line or both sides all put, only put single side and can avoid straight line run-up, put both sides and can avoid circular arc run-up and around big curved run-up.

Final step direction is incorrect, and in fosubry flop run-up is imparted knowledge to students, final step produced problem is usually relatively more serious, mainly can produce the race method of the outer Eight characters, and correct position during last take-off should still be run into along arc direction; And the take-off position that mistake technology often makes the mistake, the route of final step is caused to deviate from naturally extending of camber line, thus make lower limb produce the separation of two different directions, cause decomposition of force, and deviation point of suppon in run-up speed direction in final step support, so that cannot producing correct take-off, upper cognition swings to cross bar too early. Producing cause: having bar of hiding realize or be eager to carry on the back to cross bar action before off, take-off leg has subconsciously deviateed hop. Main teaching method: 1. repeatedly carry out upper 1-3 take-off exercise, the swaying direction of take-off leg when emphasizing to walk in final step. 2. place a mark playing hop, run into direction with what control final step; 3. place comprehensive pad or the elasticity springboard of suitable size in a hop, repeatedly carry out take-off exercise, exercise is emphasized jump onto take-off point take-off; 4. marked hop, repeatedly practised.

During Jump in Back Layout, pin position is not just, fosubry flop final step put the direction of tiptoe and take-off important on an equal basis, pin position is incorrect, can cause great impact to rising equally. Usual tyro tiptoe when take-off can produce abduction naturally, and what form the outer Eight characters puts pin action, and this kind puts pin technology, and when causing take-off, transverse horizontal speed is excessive for a moment, produces jumper bar phenomenon; Two easily cause the damage of ankle joint. Teaching means: 1. previous step puts pin imitation form work, requiring to put pin direction in exercise will be just; 2. linearly it is 1-3 between advancing and walks take-off exercise, it is noted that emphasize linearly to put pin take-off; 3. put a little mat in a hop along running into direction, it is desired to take-off on pad; 4. short distance run-up elasticity springboard take-off exercise, is placed with elastic springboard in a hop, and direction is consistent with run-up direction, it is desired to pedal take-off.
