TOOLS
Observation tools are meant to provide techniques that enhance your ability to watch for specific movements, positions, or stances. View these as resources for your observation practices.
Track in the Snow
Te track left in the snow by a snowboard never lies and can be a great tool. It removes all the mystery about whether the turn is more skidded or carved. Te phases of the turn are quite clear and turn symmetry is apparent in a snow track. Where the edge transitions from one turn to the next is also easily seen. Tracks allow you to see where the board was flattened completely or if the change was made in the air. Te track is a great indicator of when and where the new edge is engaged relative to the fall line: either in the fall line or while crossing it. Using this obvious tool provides instant and clear feedback for both instructor and student.
The Triangle
When observing, imagine the rider fitting inside a triangle – with the shape of the triangle depending on how the rider stands on the board. Te base of the triangle is the snowboard. Te sides of
the triangle come from each end of the board and meet at the rider’s head. If a rider’s stance is centered tip-to-tail on the board in a balanced, athletic posture, the triangle should be approximately equilateral. When both legs are fully extended, an isosceles triangle forms.
As the rider’s neutral stance changes, the shape of the triangle – and the rider’s ability to influence board performance through movement of the lower body – also changes. For instance, if the front leg flexes more than the back leg, the triangle becomes more like a right triangle – with a 90-degree angle at the front leg. Consequently, the rider is unable to pressure the rear of the board, the pivot point of the board moves forward of center, and the board’s tail skids out and possibly over-rotates, usually at the end of the turn. If the rear leg flexes more than the front, the right angle is formed with the rear leg. Tis rider will tend to have a prolonged turn initiation with a rapid finish.
