By applying mechanical knowledge, the authors analyzed the method used by speed skaters to in-crease the depth of the blade cutting into the ice surface and the maximum horizontal component force bearable for the ice slope which the ice striking force acts on during bend gliding by using reeded double-wedge ice skates, and revealed the following findings: reeded double-wedge ice skates used by short track speed skaters can increase the maximum horizontal component force bearable for the ice slope, let the bodies of the skaters tilt to the circle center to a greater extent, produce a greater centripetal force, so that the skaters can glide through bends at a faster speed. |
