CUES 口令
Starting position: Stand facing carriage, one foot on carriage near shoulder rest, other foot on floor, knee aligned with front of carriage. Breathing: Exhale to push carriage back, extending hip and knee; inhale to bend and return to start. Imagery: Light and powerful like pushing a scooter.
起始位：站立面向核心床，一脚踩在滑板靠近肩靠处，另一脚在地面，膝盖对准滑板前端。呼吸：吐气将滑板往后推，髋膝关节伸立；吸气弯曲回到起始位。想象提示：像蹬滑板车一样轻快有力。
IMAGERY 意象
【Direct】Keep the center of the supporting knee aligned with the second toe, focusing on maintaining a constant height of the greater trochanter in space as the carriage opens. During the carriage movement, focus on centering the humeral head within the joint socket to avoid shrugging or excessive forward leaning. Maintain horizontal pelvic alignment through deep abdominal indrawing, ensuring the sacrum does not rotate with leg extension. 【Indirect】Poised Support Pole: Imagine your supporting leg as a sturdy pole rooted deep underground; it not only bears weight but anchors your entire center of gravity like a stabilizing needle. Accelerating Propeller: Imagine your moving leg as a submarine's rear propeller, gliding steadily and uniformly underwater to drive your vessel of life smoothly through space. Cocked Crossbow: The torso is like the rigid frame of a crossbow; though filled with internal elastic tension ready to release, the exterior remains perfectly calm and solidified. 【Space】Parallel Glass Groove: Feel your moving leg sliding within an absolutely parallel transparent glass groove; the trajectory must occur precisely along the walls without wobbling or bumping. Infinite Horizon: As the carriage opens, feel your toes attempting to slice through the air, extending to the farthest horizon behind the carriage, stretching the body's longitudinal dimension to its limit. Height Scanner: Imagine the crown of your head touching a precision infrared height scanner; during the entire movement, you must maintain a constant height, never letting the laser dot jump up or down. 【Feeling】Serene Deep Sea: Imagine moving within dense, warm deep-sea waters; every push and return of the carriage carries a uniform, controlled water resistance. Lingering Fingerprints: When holding the footbar, feel your fingertips merely sensing the surface rather than gripping tightly, shifting the support task entirely to the connection between soles and core. Stopper's Kiss: When returning the carriage, attempt an extremely silent 'air kiss' between the stopper and the frame, emitting no 'clack' sound, using this silent precision as feedback for your eccentric control.
【直接】保持支撑腿的膝盖中心始终对准第二脚趾，在滑车推开时专注于让大转子在空间中的高度保持不变。当滑车往返移动时，专注于肱骨头在关节窝内的中心化，避免因手扶脚踏杆而产生耸肩或身体重心过度前倾。通过腹壁的深层内收来维持骨盆的水平对齐，确保骶骨不随腿部的伸展而产生旋转。【间接】蓄势待发的撑杆：想象你的支撑腿是一根深扎入地下的坚固撑杆，它不仅承载着体重，还像定海神针一样锚定着你的整个重心。正在加速的螺旋桨：将你的移动腿想象成潜水艇后方的推进螺旋桨，它在水下平稳、匀速地划动，驱动你的生命之舟在空间中稳健滑行。拉满的弩机：躯干如同弩机的坚硬机身，虽然内部充满了随时准备爆发的弹性张力，但外观上却维持着极致的冷静与凝固。【空间】平行玻璃槽：感觉你的移动腿正在一根绝对平行的透明玻璃槽内滑动，动作轨迹必须精确地沿着槽壁发生，不允许有任何晃动或磕碰。无限延伸的地平线：在推开滑车时，感觉你的脚趾尖正试图划破空气，延伸至滑车后方最远的地平线，将身体的维度在纵向上拉到最长。扫描高度仪：想象你的头顶正在触碰一台精密的红外线高度扫描仪，在整个过程中，你必须维持恒定的身高，绝不让激光点产生上下跳动。【感觉】静谧的深海：想象你正置身于稠密且温暖的深海水域中做动作，每一次滑车的推开和收回都带有均匀且受控的水阻感。轻抚的指纹：在双手扶住脚踏杆时，感受你的指尖只是轻柔地感知表面，而非死命抓握，将支撑重任交给足底与核心。挡块的亲吻：收回滑车时，尝试让挡块与框架之间发生一次极致静谧的空气亲吻，绝不发出一丝喀啦声，用无声的精准来反馈你的离心控制力。
