By John Gillies – Head Coach
The demonstration training and selection process continued in January with training camps at Silverstar BC and Mont Ste Anne QC.
One aspect of the training was to develop technical similarity between skiers. To achieve this goal, skiers focused on demonstrating 3 “functions” or outcomes.
Alignment for maximum force. Stable, natural alignment is a building block for all skiing applications. It requires access to all joints and should be demonstrated in all phases of the turn. A skier’s biomechanical strength should not be sacrificed as they move through the arc and increase edging. This alignment builds momentum on an arc.
Moving arc-to-arc. This means showing a clear intention and anticipation of trajectory. It also demonstrates the turn as a moving platform, carrying momentum from turn to turn. The biomechanical principle of velocity (involvement of big joints) is an important tool to generate speed in group skiing situations.
Creating torque and reaction. Well timed angular movements, combined with muscular resistance, ski performance and impulse let skiers vary their trajectories. Torque and reaction are important tools in synchronizing with other skiers, and recovering when mistakes are made.
For steering versatility, the above principles are practiced at all speeds.In basic skiing, the turn shape is symmetrical above and below the fall line. Speed is controlled with an even track width (amount of skidding) throughout the turn and an active steering of the lower body.
This moves away from a traditional “form – based” approach where skiers work on they way they look. By focusing on simple, outcome-based objectives, similarity of form becomes a result. So far the team has responded well to this approach and the intensity is building as we move towards the final selection this April. Follow the progress of these fine skiers as they prepare for Interski 2011 in St Anton, Austria. We hope to see you there!

那位大虾解释一下 啥是 3 “functions” ?作者: lupo 时间: 2012-2-16 10:50
应该是 central and mobile stance，turn with lower body,balance on edges.作者: bullpower 时间: 2012-2-16 11:07
本人觉得这个太高级
还是先把标准的balance/stance练好
