CUES 口令
Starting position: Quadruped on carriage, hands holding foot bar. Choose spinal position based on variation: Flexion (spine curved, shoulders at 135°), Neutral (spine neutral, shoulders >90°), or Extension (thoracic extension, shoulders at 90°). Breathing: Inhale to extend hips, pushing carriage back; exhale to engage deep abdominals, returning carriage without hitting stops. Cue: Maintain chosen spinal position throughout.
【起始位】四足跪姿在滑板上，双手握脚棒。根据变式选择脊柱形态：屈曲位（脊柱弯曲、肩部135度）、中立位（脊柱中立、肩部大于90度）或伸展位（胸椎伸展、肩部90度）。【呼吸】吸气：通过髋关节伸展将滑板向后推；吐气：深层腹肌收缩，将滑板带回，注意不要撞击阻挡器。【提示】运动过程中保持脊柱形态不变。
IMAGERY 意象
【Direct】During carriage movement, focus on the independent rotation of the femur within the acetabulum, ensuring the sacrum and spinal curves do not change with carriage position. Maintain stability of the inferior angle of the scapula against the posterior ribs, using balanced arm pressure against the footbar to prevent ribcage collapse. Feel the opposition between the atlas (C1) and the sit bones toward two poles, maintaining maximum segmental space in the spine. 【Indirect】Industrial Folding Ruler: Imagine your body as a sturdy folding wooden ruler; only the hip 'hinge' is working, while the rest of the ruler remains in a locked straight line. Precision Drawer: The torso is a steady solid wood counter, and the legs are drawers running on smooth tracks, driven by core power. Balanced Spirit Level: The body is like a construction level; no matter how fast the carriage moves, the colored bubble (center of gravity) must stay steadily within the center markings. 【Space】Virtual Ceiling: Imagine an extremely thin virtual glass plate hovering above your back; as the carriage returns, keep your back close to but not shattering the glass. Button on the Back: As the carriage opens, imagine trying to touch a micro-button on the back wall with your tailbone, extending the lower limbs infinitely into space. Filled Mold: Use your abdomen and lower back to fill the invisible air molds around your body, ensuring the volume of the trunk remains full rather than collapsing upon impact. 【Feeling】Viscous Honey (Kinesthetic): Feel the air becoming like warm, viscous honey; every trip of the carriage must overcome this uniform resistance, creating a silky and resilient movement quality. Maglev Track (Tactile): Feel a maglev-like zero-friction sensation between the rollers and the metal tracks, requiring deep abdominal tension to 'brake' and start. Silent Muting (Auditory): Listen quietly to the sliding sound; strive for 'silent operation,' letting any sound of the carriage meeting the frame dissolve completely into your breath rhythm.
【直接】在滑车推拉过程中，专注于让大腿骨（股骨）在髋臼内独立转动，确保骶骨与脊柱的弧度不随滑车位置而改变。维持肩胛骨下角在肋骨后侧的稳定，通过手臂对脚踏杆的均衡推力，确保护胸廓不因弹簧拉力而塌陷。感受寰椎（第一颈椎）与坐骨向两个极点对拉，在动态往返中维持脊柱最大的节段间隙。【间接】工业折叠尺：将你的身体想象成一把坚固的折叠式木工尺；只有髋关节这个‘铰链’在工作，其余的尺身始终维持锁定的直线状态。精密抽屉：躯干是一座沉稳的实木柜台，而双腿则是运行在顺滑轨道上的抽屉；由核心动力驱动抽屉的开合。平衡的水平仪：身体像是一个建筑水平仪；无论滑车移动得有多快，内部的彩色液泡（重心）都必须始终稳稳地停留在中心刻度线内。【空间】虚拟天花板：想象你的背部上方悬浮着一层极薄的虚拟玻璃板；在推回滑车时，保持背部紧贴但不击碎玻璃。背后的按钮：推开滑车时，想象你正试图用尾骨去触碰房间后方墙壁上的一个微型按钮，让下肢向空间的深处无限延伸。充盈的模具：用你的腹部和后腰去向外填满身体周围的隐形空气模具，确保在滑车回位时身体的体积感依然饱满。【感觉】粘稠的蜂蜜（动觉）：感受空气变得像温热且粘稠的蜂蜜；每一次滑车的往返都必须克服这种均匀的阻力，带出一种丝滑且具有韧性的动作质感。磁悬浮轨道（触觉）：感觉滑车滚轮与金属轨道之间存在一种磁悬浮般的零摩擦感；这要求你必须运用深层腹肌的张力来控制起停。静谧的消音（听觉）：静静听听滑车滑动的声音；尝试实现极致的‘静音运行’，让滑车与框架接触时的响动完全消融在你的呼吸律动中。
TACTILE CUES 触觉提示
Lightly touch lower abdominals to cue engagement; hand above sacrum to cue pelvic stability; lightly touch scapulae to guide shoulder girdle alignment.
轻触下腹部提示腹肌收缩；手置于骶骨上方提示骨盆高度稳定；轻触肩胛骨指引肩带排列。
PROGRESSION 进阶
Single-leg variation (R-Quadruped); eyes closed.
单腿练习（R-Quadruped）；闭眼练习。
REGRESSION 退阶
Increase spring tension to assist return; reduce range of motion.
增加阻力以辅助回程；减小动作幅度。
COMMON ERRORS 常见错误
Inability to maintain spinal position; carriage not moving; shoulder movement substituting hip movement; jerky, unrhythmic motion; ineffective hip flexor stretch during extension.
