All objectives of the study were met, proving the suitability of the proposed technology for scientific and applied technique evaluations of downhill skiing. Step 3 presents a case study where the technique analysis methodology is applied to advise an individual skier on potential technique improvements. In step 2, the techniques parallel and carving turns were compared.
The obtained data was used to establish a PM-coordinate system for skiing movements.
In step 1, certified ski instructors skied specified technique elements according to technique variations described in ski instruction curricula. The approach utilizes an inertial measurement unit system (Xsens™) and presents a motion analysis algorithm based on the Principal Movement (PM) concept. The current paper describes a 3-step proof-of-concept study introducing a technology platform for quantifying skiing technique that utilizes the practitioners’ expert knowledge. While scientific understanding of skiing technique is still incomplete, not least due to challenges in objectively measuring it, practitioners such as ski instructors have developed sophisticated and comprehensive descriptions of skiing technique.
