Hockey Acceleration - PUSH (hip-knee extension)

To accelerate effectively a skater must PUSH against the ice with each leg.  This PUSH is accomplished through a rapid hip and knee extension - occurring in the leg in contact with the ice.  The peak extension speed of the hip and knee should be reached simultaneously to apply the greatest amount of vertical and horizontal force.  Peak joint angular speed/force application should occur in the stance phase generation about half way between mid-stance and toe-off to be most effective in creating acceleration.
