CUES 口令
Starting position: Sit on front edge of carriage, hold foot bar, toes against carriage edge. [Tendon] Exhale: Push carriage with feet, keeping arms and legs straight, spine rounds back; Inhale: Lift back to start. [Gymnast] Exhale: Push carriage with feet, bend elbows, spine lowers with control; Inhale: Straighten arms to push up, return to start.
【起始位】坐在滑板前缘，手抓脚棒，脚尖抵住滑板边缘。[Tendon]吐气：脚推滑板，保持手臂与腿伸直，脊柱向后屈曲；吸气：抬起回到起始位置。[Gymnast]吐气：脚推滑板，手肘弯曲，脊柱控制性下移；吸气：手臂直推上推，回到起始位。
IMAGERY 意象
[Tendon Stretch]【Direct】Press the metatarsals firmly against the footbar, initiating the lower abdominals to lift the center of the pelvis vertically upward away from the heels. During the descent, maintain the connection between the lower rib margin and the pubic bone, ensuring the spine maintains a full arc without lumbar hinges. 【Indirect】Industrial Spring: Imagine your body as a high-strength industrial compression spring, with the core as the sole power source driving both ends toward the center. Heavy Bow: The torso is like a fully drawn heavy bow; each exhalation and abdominal contraction makes this bow rounder and more explosive. 【Space】Narrow Funnel: Feel as if you are trying to squeeze your body into the bottom of a narrow funnel; you must contract your core and lift as high as possible to pass through the tightest point. Filling Negative Space: Use your back to broaden the boundaries of the surrounding 3D space, letting the spinal flexion fill every inch of negative space above the carriage. 【Feeling】Vacuum Suction: Feel a powerful vacuum suction in the abdomen that counteracts body weight, making you feel as though the pelvis is weightlessly escaping gravity. Resonant Hum: Imagine the spine emitting a low-pitched metallic resonant hum as it moves, feeling the steady, industrial quality of the movement. [Gymnast]【Direct】Infinitely lengthen the atlas at the crown and the tailbone in opposite directions, maintaining consistent spinal alignment as the carriage opens. Focus on the centered positioning of the humeral head within the joint socket, using the power of the serratus anterior to push the ribcage away from the footbar. 【Indirect】High-Speed Arrow: Imagine the body as a high-speed arrow frozen in time and space, with an unswerving piercing force running from fingertips to toes. Laser Level: The torso is like a precision laser level; no matter how the carriage moves back and forth, your central axis maintains absolute linear accuracy. 【Space】Parallel Rails: Feel as if you are suspended between two absolutely parallel rails; the body must slide within the vertical plane defined by the rails without any lateral deviation or collapse. Constant Light Ring: Imagine a circular ring of light radiating from your core; as the movement progresses, the height of this ring in space remains constant. 【Feeling】Violin String: Feel the whole body like a taut violin string; though bearing the spring's tension in motion, it maintains a high-frequency, tight vibration internally. Liquid Steel: Imagine your limbs are cast from liquid steel, possessing both extreme fluidity to move the carriage and indestructible hardness to support the torso.
[Tendon Stretch]【直接】将趾骨稳固地压在脚踏杆上，启动下腹部将骨盆中心垂直向上提拉，使其离开脚后跟。在下落过程中，保持肋骨下缘与耻骨的连结感，确保脊柱维持饱满的圆弧，而不产生腰椎折点。【间接】高强度弹簧：想象你的身体是一个高强度的工业压缩弹簧，核心是驱动两端向中心汇聚的唯一动力源。重型弓背：躯干如同一个被拉满的重型弓背，每一次呼气收腹都让这张弓变得更加圆润且充满爆发力。【空间】狭窄漏斗：感觉你正试图将身体塞进一个狭窄的漏斗底部，你必须尽可能收缩核心并向上拔高，以挤过那道最窄的关口。填充负空间：用你的背部去拓宽周围三维空间的边界，让脊柱的屈曲填充滑车上方的每一寸负空间。【感觉】真空吸力：感受腹部产生一种强效的真空吸力，这种吸力抵消了身体的重量，让你感觉骨盆正轻盈地脱离重力干扰。金属共鸣：想象脊柱在移动时发出一声低沉的金属共鸣，感受动作中蕴含的沉稳、工业般的质感。[Gymnast]【直接】将头顶寰椎与尾骨向两端无限拉长，在滑车推开的过程中，维持脊柱的一致性排列。专注于肱骨头在关节窝内的中心化定位，利用前锯肌的力量将胸廓推离脚踏杆。【间接】高速箭矢：想象身体是一枚被凝固在时空中的高速箭矢，从指尖到足尖贯穿着一股不容偏移的穿透力。激光调平尺：躯干如同一根精密的激光调平尺，无论滑车如何往返移动，你的中心轴始终维持着绝对的直线精度。【空间】平行铁轨：感觉你正悬浮在两条绝对平行的铁轨之间，身体必须保持在铁轨限定的垂直平面内滑动，不允许有任何侧向偏移或塌陷。恒定光圈：想象从你的核心向外辐射出一道环形光圈，随着动作的进行，这道光圈在空间中的高度始终保持恒定。【感觉】提琴弦：感受全身像一根绷紧的提琴弦，虽然在动态中承受着弹簧的拉力，但内部维持着极高频率的、紧致的颤动感。液态金属：想象你的四肢是液态金属铸就的，既具有极强的流动性来推动滑车，又具备无坚不摧的硬度来支撑躯干。
TACTILE CUES 触觉提示
Lightly touch inferior angle of scapulae to cue stability; hand on abdominals to cue deep core engagement; guide spinal curve.
手轻触肩胛下角提示稳定；手置于腹部提示核心深度收缩；引导脊柱弧度。
PROGRESSION 进阶
Perform in middle of carriage to increase difficulty.
在滑板中段进行练习增加难度。
REGRESSION 退阶
Reduce range of motion; increase spring tension for buoyant return.
减小移动幅度；增加弹簧重量以增加回程的浮力感。
COMMON ERRORS 常见错误
