【摘要】：目的:采用三维高速摄像对被测的八名规范掌握该项技术羽毛球专项班男子的正手网前勾对角球技术进行运动学分析。揭示羽毛球网前正手勾对角球技术的空间运动规律和特征,通过移动取位阶段,引拍阶段,击球阶段,随拍阶段的身体各关节角度特征变化。得出相关的运动学参数,找出运动员身体姿势的运动特征。通过数据的分析和对教学的启示,找出问题所在。通过差距的比较,使教师和学生认清该技术动作的实质和技术关键,形成科学的理论指导和教学方法,完善科学训练体系。方法:本研究用两台型号、规格相同的高速摄像机,拍摄过程频率均为120HZ,拍摄对象为西安体育学院规范掌握该项技术羽毛球专项班的八名男子(均右手持拍),通过专家现场选取认为击球动作最好的一次作为研究动作录像,采用美国Ariel分析系统完成三维解析,对技术动作进行技术特征分析。结论:1.移动取位阶段是正手网前勾对角球的关键阶段,它决定着运动员以后阶段的顺利进行,测试的八名运动员在移动取位阶段身体姿势站位,符合下一步动作技术的进行。2.引拍开始到引拍结束时刻身体上肢右肩的角速度变化较大,差异比较明显,而从引拍开始时刻到引拍结束运动员下肢髋关节角速度变化值越来越小,逐渐趋于一个稳定状态。3.引拍阶段右肩、右肘、右膝、右踝关节角度过大或者或小直接影响下一步技术动作的开始,影响击球质量。4.击球阶段身体各关节角度从开始增加到最大值,八名运动员肘关节角度变化差异较大,从击球开始到击球结束时刻腕关节角速度变化比较明显,差异显著。5.运动员击球后进入随挥阶段身体各关节角度逐渐较小,而且上肢肩关节、肘关节、腕关节继续做鞭打动作,同时身体下肢体向后并步后撤回位,角速度变化不明显。
[Abstract]:Objective: to analyze the kinematic analysis of the corner ball technique in the forehand net of the eight standardized badminton special class men who have mastered the technical badminton special class, and reveal the spatial movement and characteristics of the corner ball technique in front of the badminton net. Through the analysis of the data and the Enlightenment of the teaching, we find out the problems. Through the comparison of the differences, teachers and students can recognize the essence and technical key of the technical movement, and form scientific theoretical guidance and teaching methods. Good scientific training system. Methods: This study uses two types of high speed cameras with the same specifications, and the frequency of the shooting process is 120HZ. The target is eight men (all right hand holding) for the special class of the technical badminton ball in Xi'an Physical Education University. The video, using the American Ariel analysis system to complete the three-dimensional analysis, the technical characteristics of the technical analysis. Conclusion: the 1. moving extraction stage is the key stage of the corner ball in front of the forehand network. It determines the smooth progress of the athletes in the future stage. The eight athletes in the test are moved to the position of the body position at the stage of removing the position, which is in line with the next step. The angular velocity of the right shoulder of the upper limb of the body was changed greatly at the beginning of the.2. racket at the end of the beat, and the difference was obvious, while the change value of the hip angular velocity of the lower limbs of the lower extremities was getting smaller and smaller from the beginning of the start to the end of the beat, and gradually tended to a stable state of the.3. racket order Duan Youjian, the right elbow, right knee and right ankle joint angle was too big. Or or small direct impact on the beginning of the next step of the technical movement, the impact of the quality of the ball in the.4. stage of the body angle from the beginning to the maximum, the angle of the elbow joint of the eight athletes varies greatly, from the start of the hit to the end of the ball, the angular velocity of the wrist is more obvious than that of the.5. player after hitting the ball. The angles of each joint of the body gradually smaller, and the shoulder joints of the upper limbs, the elbow joint and the wrist joint continue to do the whipping movement, while the lower limbs of the body are withdrawn back and after the step, the angular velocity is not changed obviously.
