FIELD: sport; games.
SUBSTANCE: combined artificial ice cover of skating ring consists of at least one low layer and frozen top layer containing additives from low-molecular polymer in the amount from 0.1 ppm to 10 ppm and ammonia from 1 ppm to 100 ppm. Top layer of ice cover is no more than 1 mm thick at straightway of skating ring, and thicker at curvilinear sections, i.e. turns, but no more than 2 mm. In addition, ice cover surface temperature is higher at curvilinear section as compared to straight sections of skating ring by 1-2°C.
EFFECT: improved movement of sportsmen at turns and possibility to describe turns at higher speed.
