CENTER OF BALANCE, AXIS, TILTING, PLANES, ROTATIONS
Center of Balance: Is located at the center of mass, where the three axis intersect.
Balance Point: Is where the forces on the body are equal to the forces created by the dynamic body actions
Body Segments: The body is divided into several sections; the upper body and lower body are two of the major segments
Vertical Axis: Runs from the top of the body to the feet, through the balance point.
Horizontal Axis: Runs from side to side, through the balance point.
Lateral Axis: Runs from front of the body to back of the body, through the balance point.
Tilted; One or more of the axis of rotation are less than 90 degrees to the direction of the rotation.
Off Axis; The rotation around the primary axis is tilted off of the axis.
Direction of Travel; The primary direction of travel is in the horizontal plane and thru the balance point. There are lateral movements around the body segments during flexion and extension.
Plane; There are three planes which the body pass through during dynamic movement, the vertical plane, lateral plane and horizontal plane.
Flexion: decreasing the angle between the joint or body segment
Extension; increasing the angle between the joint or body segment
Rotation; increasing or decreasing the different angles between the body segments
Degrees of Rotation; The number of rotations or part of rotations around an axis expressed in degree of rotation.
Primary Axis; the body actions to rotation on the first axis
Secondary Axis; the body actions to rotation on an additional axis
Grabs: With the body action of a flexion, a section or part of the ski is grabbed by the hand or hands.
Holds: With the body action of a flexion, a section or part of the ski or skis is grabbed by one or more hands and then held for a duration.
