The study was designed to find the most efficient method of the ski sliding quality improvement based on a comparative analysis. For the purposes of the comparative analysis of the race ski sliding quality improvement methods, the authors selected and applied the following key performance criteria:
- Temperature range of the coating;
- Coat application frequency;
- Coat stability under a variety of conditions over the race distance;
- Momentary accelerations in the start up of the ski race and prior to descent; and
- Sliding stride length.
The study found that a fluoroplastic (teflon) coating on the sliding surface of a ski offers the highest promises for the ski sliding quality improvements.

Keywords: ski sliding surface, sliding qualities, fluoroplastic, paraffin, ski wax, topography.
