Analysis Of Technical Movements And Technical Training Method Of Throwing Solid Ball Into The Ground After The Hand

Since 2006, when the hand after throwing solid ball was listed as Guangxi sports college entrance examination. Prior to this, the project did not appear as a competitive sports event in the big game, the general is just as a quality training program. The project is more and more attention by the Guangxi sports teachers and sports college entrance examination after the introduction of the sports college entrance examination. As a new sport, the total score of the total score in the college entrance examination in our district accounted for 25 points (sports college entrance examination score of 100 points). However, due to the lack of a more perfect technical principle of the project, there is no unified teaching method and training method. According to the characteristics of in situ hands after throwing solid ball, combined with other items, summed up in the project on a unique set of training methods, therefore, physical education teachers in the project training method can be said to be a physical education teacher each one has its own merits, each have their own characteristics and shortcomings in the project training method on.In this paper, we use the method of documentation, collect the technical action analysis and technical training method of the ground and hands before and after the application of the technology, and use the contrast experiment method, mathematical statistics method, sum up method, calculation method, logical analysis method To better develop students’ physical quality, improve the technical structure theory system and training method system of the project, and guide the students to train the sports college entrance examination. Research shows:Firstly,The existing problems in the technical analysis of the solid spheres are:the analysis of the technical principle of throwing solid ball into the ground. Although there are some factors that affect the performance of the project, and there is no explanation to the extent of the angle range from the point of view.There is no analysis on the maintenance of body balance after the instrument is maintained, and the method of grip is not combined with the characteristics of the acceleration of the pre swing phase.Secondly, in both hands after throwing the shortcomings of solid ball training method: in the holding phase of the training equipment, did not fully take into account for students to reduce the error rate of hand instruments related training. In the training method to improve the speed of the device, the arm strength training method is not entirely the special strength training method, the active muscle and passive muscle of the project.Thirdly, after calculation and derivation, the in situ hands after throwing solid ball the actual achievement and release height, hand speed, angle and the relationship between the length of the arm is::S=VCOSα/g(VSinα+(1/2)2gH+V2Sin2α) - 1 手臂 Sin α; angle about 36-41 degrees; method of holding instruments to start end characteristics of students the pre swing phase, effectively prevent the equipment dispose of; in the final force, to do stretching speed, lift the upper body and arm to swing faster. In the process of training the active muscle, can not ignore the training of the confrontation, to prevent the injury of the waist and leg muscle strain. Fourth, in both hands after throwing solid ball training methods:holding instrumentscan be used interchangeably to catch stage hands shot, finger push ups, standing continuous fist, a small dumbbell valgus and related equipment training methods (such as:grip, grip ring). The final stage combined with the movement characteristics of the project, identify the active muscle and antagonistic muscle, which means the barbell squat or squat, continuous jump step exercises, jumping exercises to strengthen students’high touch legs; by dorsal flexion, two from the prone position, legs bowed training means to strengthen the power of the waist by students; put a barbell, standing flexion hands after the rejection of barbell sheet, rubber band practice to improve students’arm strength. In the control angle, it can be controlled by the direct control method, the reference control method, the camera method three methods, more effective control of the angle of the students.
