老大以前卖过一本书，我倾家荡产给买下了。 现在拿出来在看看。
新感想就是EXTENSION不是说就非得伸直了，而是伸直的过程， UNBENDING，LENGTHING 不是 STRAIGHTENING
TERMINOLOGY
Angulation: the lateral angles formed between segments of the body.
Balance: the use of the neuromuscular system to maintain an athletic posture and alignment of
the COM and BOS.
Banking: the tipping of the shoulders and the upper body into the turn. It generally is an unstable
position, and it is often associated with rotation. Synonym: tipping.
Base of Support (BOS): the area between all points that support the body. It generally is referred
to as the feet, but it is any point of snow contact including skis and poles.
Carving: turns with little or no skidding, with the tails of the skis following the tracks made by
the tips.
Christie: a turn or part of a turn, done with the skis parallel.
Centre of Mass (COM): the three dimensional balance point of an object.
Counter-rotation: the action of upper and lower body turning against each other, based on
physical principle of an action having an equal and opposite reaction. If upper or lower body are
turned, the other segment will turn in the opposite direction. A weak force and most effective if
the skis are un-weighted.
Cross-over: the crossing of the trajectories of the COM and BOS between turns; related to edge
change.
Edge angle: the lateral angle formed between the base of the ski and the slope.
Edge change: the change of balance from one edge (or edges) to the other.
Extension: the lengthening of the body by un-bending joints. Opposite of flexion.
Fall Line: an imaginary line following the inclination of the slope at any point. Where a snowball
would roll if released on the slope.
Flexion: the shortening of the body by bending joints. Opposite of extension.
Inclination: the degree of lean used to balance against the external forces generated by turning.
Lead change: the natural tendency for the inside ski to be ahead as a result of the lower body
turning.
Line of motion: the path that the COM follows.
Linking: the smooth transition between turning arcs. Related to edge change.
Movement: body actions initiated by internal muscular efforts. Can affect balance on all planes.
Parallel: a position of the skis where the longitudinal axes are parallel and edge angles are the
same.
Rotation: the twisting of the hips or upper body into the turn, often causing imbalance.
Self steering of skis: the inherent turning tendency of skis, due to sidecut and longitudinal flex.
Separation (upper and lower body): refers to the steering effort being led by the lower body,
with the upper body naturally facing the direction of travel, or the tangent of the arc.
Sidecut: the shape of the ski defined by the width underfoot versus width tip and tail.
Ski reaction: the use of stored energy in ski and boot to provide rebound for turn linking.
Skidding: the sideways travel of one or both skis across the snow. Necessary for speed control.
Sliding: the forward travel of one or both skis on the snow.
Steering: the blend of edging and pivoting with the control of the resulting pressure. Steering
allows the skier to choose a variety of turn shapes. Different blends of edging and pivoting allow
the skier to control speed or to maintain speed or accelerate by reducing braking.
Steering angle: the angle formed between the longitudinal axis of the ski and the direction of
travel of the skier.
Stem: a position of the skis where the tails are further apart than the tips. Seen in Wedge
(snowplow) turns as a braking or steering device, or if the tail of the downhill ski skids more than
the tip.
Stepping: a step, or transferring of weight from one ski to the other.
Tipping: the tipping of the shoulders and upper body into the turn. Generally unstable position,
and often associated with rotation. Synonym: banking.
Traverse: sliding forward on edges at angle to the fall line.
Wedge: ski position with tips together and tails apart. See Stemming.
Weighting/Unweighting: the control of the load or pressure against the snow. Affected by
moving COM quickly up or down, by increasing or reducing steering, and by the muscular forces
applied by the skier. |
