【摘要】：竞技体育运动成绩和能力的逐步提高对训练的科学化水平提出了更高的要求,其中对运动员的动作重现仿真是重要研究方法和手段;而3DVR(三维虚拟现实)技术以其较强的交互性、实时性和沉浸感受到了科研人员的青睐,成为科技服务流程中数据重建和演示环节的重要手段。短道速滑一直是我国传统优势项目,在短道速滑500 m比赛中,起跑阶段占据有利位置对比赛的整个进程有重要影响,如果能够抢先进入弯道,就可以为后续的滑跑阶段奠定良好的基础。2015年国际滑联修改短道速滑起跑规则后,起跑技术向多元化发展。本文用三维录像解析法对2016/17国际滑联短道速滑世界杯上海站500 m比赛中武大靖改用侧向式起跑动作和一直使用侧向式起跑动作的加拿大名将查尔斯·哈梅林的技术进行解析,获得运动学数据调入虚拟现实系统进行三维重建演示,从而进行比较分析。研究表明武大靖在本次比赛中起跑效果稍好于查尔斯,说明武大靖对新技术的学习及掌握能力较强,建议其训练过程中应注重起跑反应能力的练习,增大起跑技术动作的稳定性,同时应加强右侧下肢的力量性练习。
[Abstract]:The gradual improvement of the performance and ability of competitive sports puts forward higher requirements to the scientific level of training, among which the simulation of athletes' movement reproduction is an important research method and means. 3DVR (3D Virtual reality) technology, with its strong interactivity, real-time and immersion, has become an important means of data reconstruction and demonstration in the process of science and technology services. Short track speed skating has always been a traditional advantage event in our country. In the 500m short track speed skating race, the starting stage occupies a favorable position and has an important influence on the whole process of the race. It can lay a good foundation for the following running.After the International Slide Federation modifies the start rules of short track speed skating in 2015, the starting technology will be diversified. In this paper, using three-dimensional video analysis method, the Canadian famous athlete Charles Hamelin, who has been using the lateral start and has been using the lateral start, has been used in the 500m short track speed skating World Cup Shanghai Station of the 2016 / 17 International Slide Federation. To parse the technology, The kinematics data are transferred into the virtual reality system for 3D reconstruction demonstration, and then comparative analysis is carried out. The research shows that the effect of Wudajing in this race is slightly better than that of Charles. It shows that Wudajing has a strong ability to learn and master new technology. It is suggested that the training process should pay attention to the practice of starting reaction ability. Increase the stability of the starting movement, and strengthen the strength of the right lower extremity.
