摘　　要：蛙泳是典型的技巧类运动项目,对技术动作的认知与理解程度,决定了蛙泳学习的效率。在蛙泳教学中,由于学生对自身动作缺乏正确和直观的理解,造成教学效率低下。从蛙泳教学的特点及需求出发,以自主研发与有效整合利用现有软硬件设备相结合的方式,设计与开发了蛙泳教学视频分析与反馈系统。该系统可以实现课堂动作快速反馈、技术动作横向与纵向比较、视频网络共享与交流等功能。系统硬件具有视频清晰、信号传输稳定、可靠、系统软件界面友好、操作简便、容错技术好等特点,具有较好的应用与推广价值。该系统的研发与应用对于其他体育项目的教学反馈也具有一定的借鉴意义。The breaststroke is a kind of skilled movement which needs performers to coordinate the whole body well. The cognition and understanding of the movement determines the learning efficiency of breaststroke. In breaststroke teaching, many students have low learning efficiency due to lacking of in- tuitive understanding of their own movement. In this paper, video analysis and feedback system using in breaststroke teaching was researched and designed based on independent development and integra- tion of existing software and hardware equipment. The system can be used in movement timely feed- back, movement longitudinal comparison and crosswise comparison, video sharing and discussion on the internet. Combined with advantages of high video resolution, stable and reliable in signal transmis- sion, user-friendly interface, simple and practical, the system has well application value. Besides, this system may provide suggestions to instructional video feedback of other sport items.
