The purpose of this study was to examine the effects of using aforce measurement device on riding technique in mogul skiing. Amock-up version of such a device was positioned between ski bootand binding. Data on three-dimensional kinematics and perceptionwere collected for eight subjects skiing down a mogul course.Parameters analysed were knee angle, side and forward lean ofthe trunk and hip, and the path of the body’s centre of mass. A perceptionquestionnaire was used on selective aspects to assess theskiers’ perception of the performances. Perception ratings showedno significant detrimental effects. All assessed components showeda trend of improvement from the first to last run, thus suggestingfamiliarisation was achieved. Kinematic analysis revealed that nosignificant alterations occurred. In conclusion, it is intended toutilise a functional force plate similar to the one presented byKiefmann et al. (2006) for future studies in freestyle skiing.
