Another factor of interest – is deviation in the blades under the influence of pressure on them. If the force of the pendulum will be applied in the plane of the blade, the blade deflection away from a given trajectory will be impossible, but the force of the pendulum will make a more acute angle with ice, especially in the late effort than the blade. This means that as soon as the place pressure moves to the front of the shoe rack, blade bending efficiency is lost. Perhaps this is the reason that the next blade, left on ice after rolling is done right. «Small outer curl» leave the blade on the ice, may be the result of something else. Especially in ordinary skating – is the result of a slight edge over the rolled end of the track, before the separation of ice.
If the sprinter prepared enough and rides on the common skate, the stiffness of the end of the blade is an advantage. Bending makes it difficult to trace out the passage of the segment to the desired path. With the gags this factor is leveled as the pressure point will never be placed in front of the axis of the mechanism.
