In the study of sports biomechanics, alpine skiing injuries have always demanded significant attention. In order to aid in understanding the loading phenomena associated with alpine skiing, a new research binding system has been designed which enables both the recording of boot loading data and actively controlled release of the skier's boot from the ski. The new research binding system consists of three hardware components, a dynamometer which senses all six load components at the boot/ski interface, an electromechanical device capable of releasing the boot from the ski, and a new general purpose microprocessor-based data acquisition and release control module. Constructed integrally with the dynamometer, the release mechanism is activated by electrical command from the control module. The mechanical and electrical design features of the dynamometer/release mechanism as well as important features of the hardware and software of the data acquisition and control module are briefly discussed. The system has been tested both in the laboratory and on the ski slopes. The emphasis of this paper is on the boot loading data acquired through field testing and observations on the loading environment during common recreational skiing maneuvers. Through analysis of the data, insight into both the style and safety aspects of alpine skiing is gained.
在体育生物力学研究中，高山滑雪损伤一直备受关注。为了有助于理解与高山滑雪相关的负荷现象，设计了一种新的研究绑定系统，该系统既能记录靴子的负荷数据，又能主动控制滑雪者的靴子与滑雪板分离。新的研究绑定系统由三个硬件组件组成，一个测力计，用于感测靴子/滑雪板界面处的所有六个负荷分量；一个机电装置，能够使靴子与滑雪板分离；以及一个基于通用微处理器的数据采集和释放控制模块。释放机构与测力计一体构建，由控制模块发出的电指令激活。简要讨论了测力计/释放机构的机械和电气设计特点以及数据采集和控制模块的硬件和软件的重要特点。该系统已在实验室和滑雪场进行了测试。本文重点关注通过现场测试获取的靴子负荷数据以及对普通休闲滑雪动作中负荷环境的观察。通过对数据的分析，深入了解了高山滑雪的风格和安全方面。
