WebSep 13, 2024 · A skater with speed v moving in a circular motion with radius r is accelerating with v 2 /r (the centripetal acceleration) towards the centre of the circle. The ice must then push on the skate(s) with a force . If a skater maintains the radius, a change of direction will be achieved without providing additional energy.

WebThe force produced to propel a body forward in speed skating is directed almost perpendicularly to the forward motion, because a skate moves nearly frictionless in the fore–aft direction, and is more or less fixed (against the ice) in the sideways lateral direction, resulting in a sliding point to push off against. WebOn the straight high-speed film, push-off force and EMG data were collected. An inverse dynamics analysis was performed in the moving reference plane through hip, knee, and ankle. RESULTS Skating velocity increased 5% as a result of an increase in mean power output of 25 W when klapskates were used instead of conventional skates.
