Description

A kind of shot standing throw technical modelling device

Technical field

The utility model relates to a kind of physical education equipment, specially a kind of shot putting simulator.

Background technique

The technical movements of shot standing throw include:

1, hold the shot hand the five fingers naturally separate, ball be placed on food, in, the third finger root at, thumb and little finger of toe are helped in the two sides of ball, The stability of ball is held in wrist dorsiflex increase, prevents shot from sliding, and gives full play to the strength of wrist and finger, obtains shot faster Initial velocity.

2, after holding good shot, ball is placed at clavicle nest, is affixed on neck, lower jaw is turned right, and right arm bends elbow, palm inward, on Arm is flushed with shoulder or slightly below shoulder, lifts on left arm nature, two fronts at eye level.The method for holding shot is fairly simple, but acts Correctness is grasped to obtain, large effect can be generated to sliding steps and final force movement.

3, terminate to shot from hand final force is before left foot landing, be the key link of Shot Put Techniques, movement Correctness directly affects shot muzzle velosity of throw from finger, angle of trajectory and height of selling；Correctly movement, shot muzzle velosity of throw from finger Contribution rate be up to 80%--85%；Angle of trajectory is usually 35--39 degree；Height of selling is that arm throwing is attainable best Highly, technical movements are as shown in Figure 1.

When sliding steps, which terminates right crus of diaphragm, to land, right leg, which is pedaled rapidly, to be turned, and left foot actively lands.After sliding steps, right hip is to throwing Direction rotation, effort holding shoulder axis and hip axis tighten posture, and upper body is gradually lifted in rotation.To accelerate upper body rotation and lift It rises, left arm draws from front to direction of bowl and swings, and makes body by going to side to direction of bowl back to direction of bowl.Shoulder axis at this time Hip axis, left arm and left shoulder height are still lagged behind in right shoulder, weight is most of still on the right leg that bending compresses, and body forms side bow Posture, the muscle group of elongation create favorable conditions at gesture pending for the movement of trunk final force.

In teaching, for the technical movements for throwing students standing shot putting, the existing teaching pattern of school is equal It is using practical training mode, since number of student is more, the grasp of technical movements varies with each individual, and influences teaching efficiency and teaching matter Amount.

Therefore, how prior art defect is solved, is urgent problem now.
