| Popis: | When sharpening ice hockey blades a hollow is created at the running surface of the blade. This study aimed to quantify the effect of different blade hollows on (a) blade–ice friction, (b) skating performance in an agility course, and (c) players’ perception of blade sharpness, performance, and comfort. Friction was quantified by measuring the deceleration of a sled running on the blades. Skating performance was tested with 15 volunteers performing a total of 9 trials on 3 different hollow radii. Perception was assessed using a questionnaire. Friction increased with decreasing hollow radius. Skating performance was significantly impeded at a hollow radius of 3.18 mm. Within the range of 9.53–22.23 mm performance differences were subject specific and several subjects showed no differences. Players appeared to be not sensitive enough to identify hollow radii, and only half of the subjects ranked their performance correctly. |
