Abstract
The present invention relates to a rear high-position foot-propping pedal and rear foot-propping pedal, in which the rear foot-propping pedal is mounted on the main rod, and perpendicular to said main rod, and said rear foot-propping pedal is equipped with a supporting board. When ready for starting, both hands are supported on the ground, front foot is supported on the front foot-propping pedal, and the tiptoe of the rear foot is placed on the supporting board, the sole of the rear foot is supported on the rear foot-propping pedal, and the knee is placed on the ground surface. The use of said invented starting block can make the technical movement of runner reasonable, and can raise running speed.
Description
The invention belongs to sports equipment, is a kind of block that short distance is run that is used for.
At present, the block that is used for the short distance runing competition is made up of preceding block and back block, and single setting or combination are provided with, and the pedal plate that supports of block is flat on ground, forms certain angle to layback.The block clearance time both feet palm is stepped in front and back and is supported on the pedal plate, scrunches to pedal plate, forms the reaction force to the front upper place, after pedal end, active force is shown to the front upper place with big bottom bands of trouser legs knee to the front upper place, and shank is folded to form operation parabolic camber line immediately, makes to finish to pedal the back leg of stretching and step out major step forward, in training process, go to limit the amplitude of oscillation artificially, both time-consuming effect is also not obvious, and as not limiting, center of gravity does not catch up with, the run disconnection of technology of generation directly influences the continuity of formation technology; Active force to the front upper place makes the centre of body weight trend that travels forward not obvious, and centre of body weight can not be in time away from foreleg fulcrum vertical direction, when foreleg is pedaled when stretching, causes the upper body upwards to scurry with the reaction force of wide-angle; It is that dead axle forms lower limb and two rigid bodies of upper limbs that human body is pedaled when stretching with the hip joint, pedal and stretch moment and elect the moment of resistance that above limb forms greater than arm to the kinetic moment that the active force of front upper place and lower limb form, the moment unbalance upper body is difficult for lifting, the difficulty that causes pushing hands significantly to swing, for solving the centre of body weight reach and raising, must form the corresponding accelerating sections technology of running, generally need 25-30 rice accelerating sections distance.
The objective of the invention is to provide a kind of and can give full play to off technical movements, make the sportsman improve the block of dash achievement.
Solution of the present invention is pedal plate to be supported in the back be installed on the mobile jib, and it is vertical with mobile jib that pedal plate is supported in the back, and it is 40-50cm that the pedal plate height is supported in the back, supports on the pedal plate in the back supporting plate is housed, and the preceding pedal plate that supports can be installed on the mobile jib, also can be provided with separately.During off the preparation,, before setting foot on, the forward foot in a step supports pedal plate at two place hands on floor of " on your marks " stage, rear foot tip is placed on the supporting plate, hind paw is stepped in the back and is supported on the pedal plate, and knee is placed on ground, and " preparation " stage buttocks slowly lifts, foreleg thigh and calf angle is controlled at about 90 degree, back leg is close to the back with full sole and is supported pedal plate, and gaskin is substantially parallel with ground, and the thigh and calf angle is controlled between the 110-115 degree, the back leg of " firing a shot " is firmly pedaled and is stretched, and impels active force to change sportsman's state of living in rapidly.
In order to make a block be fit to the sportsman of different heights, the back is supported pedal plate and is provided with slideway and alignment pin, so that the height of supporting plate can suitably be adjusted.
The moment that produces for overcoming, mobile jib rear portion length is set to 45-55cm.
The back is equiped with backing plate on the contact-making surface of pedal plate and sole, be convenient to scrunching of running shoes.
Good effect of the present invention is:
1, the back leg active force is identical with the direction of motion, increases utilization rate, produces action effect.
2, back leg is raised, after pedal active force by the parallel conduction of shank, promote the rapid forward swing of thigh, shank is directly done with the swing of thigh and is transferred action, impels the off first step to put leg and lands actively rapidly.
3, rapid forward moved centre-of-gravity is pedaled moment of stretching away from fulcrum at foreleg, and foreleg is pedaled to stretch and had an effect rational in infrastructurely, and the effect utilization rate improves, and the proal trend of center of gravity is obvious.
4, upper limbs and lower limb are that two rigid body resultant moments of dead axle are zero with the hip, are convenient to the upper body and lift with pushing hands and significantly swing.
5, shortened and impel centre of body weight to move the accelerative running section of variation, created condition for entering as early as possible in the way.
Above-mentioned good effect impels sprinting pace to be improved.
The present invention is further described below in conjunction with drawings and Examples:
Accompanying drawing is a schematic diagram of the present invention.
The present invention is supported pedal plate 3 and is constituted by mobile jib 1, preceding pedal plate 2 and the back supported, and the preceding pedal plate 2 that supports can be installed on the mobile jib 1, also can be provided with separately, and the back is supported that pedal plate 3 is installed on the mobile jib 1 and be vertical with mobile jib 1, and it highly is 45cm that pedal plate 3 is supported in the back, and mobile jib 1 rear portion length is 50cm.Support on the pedal plate 3 in the back supporting plate 4 is housed, the back is supported pedal plate 3 and is provided with slideway 5 and alignment pin 6, and the back is supported on the contact-making surface of pedal plate 3 and sole and is equiped with backing plate 7.
Claims (3)
1, a kind of rear high-lying feet-supporting starting device is supported pedal plate and constituted by mobile jib, preceding pedal plate and the back supported, and it is characterized in that: the back is supported that pedal plate is installed on the mobile jib and is vertical with mobile jib, and the back is supported on the pedal plate supporting plate is housed.
2, block according to claim 1 is characterized in that: the back is supported pedal plate and is provided with slideway and alignment pin.
