Résumé

Until now, the ice quality and its sliding characteristics after ice preparation were considered to be invariable and equal for all speed skaters. An analysis has shown that the resistance force to a skate sliding had changed greatly over time and had a pronounced extreme character. The methods to control the parameters of ice that provided all skaters with equal sliding conditions were elaborated. Searches for groups of matter, the addition of which reduced greatly skate friction, were carried out. The study of physical origin of such a phenomenon at the molecular level gave the possibilities to create the composites of organic origin, the introduction of which led to ice sliding properties' improvement by 50-60% in comparison with ice without such additions. The investigations were performed at the indoor skating rink "Krylatskoe" in Moscow; the results of investigations were partially applied during the Olympic Games in 2006 in Turin.
