The purpose of this study was to examine the effects of using a force measurement device on riding technique in mogul skiing. A mock-up version of such a device was positioned between ski boot and binding. Data on three-dimensional kinematics and perception were collected for eight subjects skiing down a mogul course. Parameters analysed were knee angle, side and forward lean of the trunk and hip, and the path of the body's centre of mass. A perception questionnaire was used on selective aspects to assess the skiers' perception of the performances. Perception ratings showed no significant detrimental effects. All assessed components showed a trend of improvement from the first to last run, thus suggesting familiarisation was achieved. Kinematic analysis revealed that no significant alterations occurred. In conclusion, it is intended to utilise a functional force plate similar to the one presented by Kiefmann et al. (2006) for future studies in freestyle skiing.
本研究旨在探讨使用力量测量装置对雪上技巧滑雪技术的影响。该装置的模型版本被放置在滑雪靴和固定器之间。对 8 名受试者在雪丘滑雪道上滑行时的三维运动学和感知数据进行了收集。分析的参数包括膝关节角度、躯干和臀部的侧倾和前倾，以及身体重心的路径。使用感知问卷评估了选择性方面，以评估滑雪者对表现的感知。感知评级显示没有明显的不利影响。所有评估的组成部分都显示出从第一轮到最后一轮的改善趋势，因此表明已经实现了熟悉度。运动学分析显示没有发生显著变化。总之，计划在未来的自由式滑雪研究中使用类似 Kiefmann 等人（2006 年）提出的功能性力量板。
