Description
Technical field
The utility model relates to sports apparatus, is specifically related to freestyle swimming stroke land drill device.
Background technology
During freestyle swimming, health is prostrate becomes streamlined at the water surface, and the muscle of back and buttocks keeps suitable tensity, keeps head steady at You Jinzhong, and trunk rotates 70 ゜ ~ 90 ゜ naturally around long axis of body is rhythmical
The one-period of freestyle swimming is divided into into water, Bao Shui, strikes, water outlet and aerial displacement arm, and these 5 is the indivisible stage.
The arm action of freestyle swimming is divided into an armful water, pushes away water, puies forward elbow water outlet and displacement arm, enters water several stage.
1, Bao Shui: wrist flexion, elbow in the wrong, palm firmly embraces water on rear side of health, and perceptual image is toward having a large ball in arms in one's arms.
2, push away water: pushing away water is the major impetus of advancing, push away water and want strong and effectively.After embracing water, bending arm is pushed away water to health rear and beat gradually directly, thigh place of striking.This action point is that shoulder will have a rotation, and arm coordinates shoulder action, and large arm inward turning, large arm drives little arm, to pusher water.Crook one's arm after pusher water the accelerator of semi-girder, palm, from upwards interior, is drawn by thigh from bottom to top.
3, propose elbow water outlet: after pushing away water to thigh side, the centre of the palm turns to thigh, and during water outlet, little finger of toe upwards, and arm loosens, bend elbow.Large arm drives forearm, and ancon is carried, and drives arm and hand to go out the water surface.Elbow in the wrong is probably about 100 °.
4, displacement arm: after carrying elbow, to health front displacement arm, elbow height is in hand, and feel feels similarly to be insert in water.
5, enter water: after completing aerial displacement arm, hand natural relaxation enters water.The place of entry of hand is stretched to head front as far as possible.Point to stretch when entering water and close up, first finger touches water, and being then forearm, is finally that large arm is inserted in water naturally.
At present in the teaching process of freestyle swimming, usual employing land drill, teaching is taught by micromotion, trainee is allowed to stand or prostrate, carry out practice arm to strike and leg footwork, and the action of complete one-period needs just can be practised in water, and at the swimming initial stage, the practice effect of a lot of student in water is unsatisfactory, can increase the psychology that they fear on the contrary.

Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
As Figure 1-4, freestyle swimming stroke land drill device, comprises the arm paddling line guide rails 1 and body supporting mechanism that are supported by multiple supporting seat 7, wherein:
Described arm paddling line guide rails 1 designs according to the paddling line of two arms in freestyle swimming;
Described body supporting mechanism comprises at least one supporting plate 4, at least one supporting plate base 6, described supporting plate 4 times correspondences arrange supporting plate base 6, supporting plate base 6 is movably installed on base by base slide rail 5, at least one bearing axis 9 is set in described supporting plate base 6, described bearing axis 9 is provided with multiple bearing 10, the end of described supporting plate 4 arranges jingle bell 3, accomplishes to draw repeatedly water, beat repeatedly leg for pointing out practitioner.
Described supporting plate 4 comprise a shoulder supporting plate 2, waist plate, crotch's supporting plate, thigh support plate, for placing shank and foot's supporting plate of shank and foot.
Described arm paddling line guide rails 1 comprises middle two the single guide rails connected, described single guide rails is closed, comprise two sections be in above and below hard tube and two sections be in front hard flexible pipe 12-1, the rear hard flexible pipe 12-2 at front and rear respectively, described front hard flexible pipe and described rear hard Hose Jacket are in described hard tube.
Described head shoulder supporting plate 2 has the hole that can hold face.
Described supporting plate 4 has the circular arc concave surface 8 for placing below health shoulder.
The both sides of described supporting plate 4 are provided with the wing plate being parallel to ground.
Described supporting plate 4 can along its longitudinal centre line clockwise, be rotated counterclockwise 35 °-45 °.
Described jingle bell 3 is fixed on the end of shank support plate by soft material.
Described base slide rail 5 is two grooves longitudinally arranged in susceptor surface.
The bottom surface of described supporting plate base 5 longitudinally arranges the projection with two groove matched in clearance.
Operation principle of the present utility model is: for the practitioner of different height, can by groove and protruding adjusting supporting board base 6 position relative to base 11, then practitioner lies prone on supporting plate, head is positioned in the hole in a shoulder supporting plate, action is carried out, meanwhile, in freestyle swimming exercise according to arm paddling line guide rails 1, in the action cycle, practitioner needs to accomplish to draw twice water, make a call to 6 legs, and in this process, whether jingle bell helps prompting practitioner action correct.
In addition, as shown in Figure 5, in freestyle swimming, the arm stroke mode of arm is divided into linear pattern, " C " type and " S " type, hand is according to (comprising adjustment " straight line ", " C " type, " S " type paddling line) during practitioner's high height and long arm adjustment paddling line, when the hard flexible pipe in front, when becoming generation " C " type (or " straight line " type) from " S " type, when can produce " having more than needed " flexible pipe, now, pull out the hard flexible pipe in front, and unnecessary flexible pipe is filled in hard tube;
When the action of arm needs to become " C " type (or " S " type) from " straight line " type, front end flexible pipe overall length can be not enough, now, pull out front hard flexible pipe 12-1 mono-segment distance, be bent into different shapes, meanwhile, be height, the brachium of satisfied different body, the length that rear hard flexible pipe 12-2 pulls out is adjusted; In addition, when practitioner will realize the different swimming position of right-hand man, regulate the shape of front hard flexible pipe 12-1, also can satisfy the demands.
Supporting plate is set to comprise a shoulder supporting plate 2, chest supporting plate, crotch's supporting plate, thigh support plate, shank support plate, because in freestyle swimming technology, health is in swimming process, the rotation of 70 °-90 ° will be done along long axis of body, this rotation is not synchronously carried out, a shoulder, chest, waist, crotch, leg rotation carry out successively, therefore the requirement that polylith supporting plate meets this motion is set, and then the complete exercise realizing the land action of freestyle swimming stroke; Aerofoil profile plate is set on supporting plate in addition, supporting plate and supporting plate base relative sliding to the limit time, meet the maximum anglec of rotation 35 °-45 ° of supporting plate.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
