BENEFITS 益处
Improves spinal articulation in flexion; enhances core control (especially eccentric); strengthens shoulder girdle stability; promotes coordination and proprioception.
改善脊椎分节屈曲的活动度；增强核心肌群的控制能力（尤其是离心控制）；强化肩带稳定性；促进身体协调与本体感觉。
TARGET MUSCLES 目标肌群
Abdominals (primary for roll up/down), shoulder girdle stabilizers (support), hip flexors (control leg position), spinal extensors (eccentric control).
腹肌（主导卷起与下放）、肩带稳定肌群（维持支撑）、髋屈肌（控制腿位）、脊柱伸肌（离心控制）。
SETUP 设置
None.
无特殊器械调节。
CUES 口令
Starting position: Supine, legs straight together, spine neutral or slightly flat. Arms by sides or overhead. Breathing/Movement: Inhale, lift legs parallel to ceiling. Exhale, draw toes toward wall behind, peeling lower, then mid back off mat segmentally until supported on shoulders, sit bones toward ceiling, legs parallel to floor. Inhale, open legs shoulder-width. Exhale, articulate spine down segmentally, legs circling out. Inhale, flex hips, legs together. Repeat 3-5x. Imagery: Rolling up like a carpet from tailbone; in shoulder stand, body like a stable lighthouse; rolling down, spine like pearls gently placed back.
起始位：仰卧，双腿伸直并拢，脊椎可保持中立位或轻微贴平地面（腰椎微屈）。手臂可放在身体两侧或举过头。 呼吸与动作：吸气，双腿平行向天花板方向伸直。吐气，将脚趾向身后墙壁方向带动，从尾骨开始将下背部、中背部逐节卷离地面，直至肩支撑位置，坐骨指向天花板，双腿平行于地面。吸气，双腿打开与肩同宽。吐气，脊椎一节一节有控制地卷回垫子，同时双腿向外画圈。吸气，髋关节屈曲，双腿收回并拢。可重复3-5次。 想象提示：向上卷起时，想象身体像地毯一样从尾骨端被缓缓卷起；在肩倒立位，想象身体像一座稳固的灯塔；向下时，脊椎像一串珠子被轻柔地放回地面。
IMAGERY 意象
Direct: Feel spine like pearls peeling off and placing back. Indirect: Rolling up like a scroll, down like unrolling a carpet. Space: Imagine disc spaces changing evenly during movement. Feeling: Focus on deep abdominal contraction and stable weight on shoulders.
直接：感受脊椎像一串珍珠从垫子上逐节剥离与落回。间接：向上如卷起一张画卷，向下如铺开一张地毯。空间：想象椎间盘之间的空间在动作中均匀地变化。感觉：注意力集中在腹部的深度收缩和肩膀的稳定承重感上。
TACTILE CUES 触觉提示
1. During roll up, lightly support sacrum, guide to roll toward ceiling. 2. In shoulder stand, lightly support hips to help alignment. 3. During lowering, lightly touch lower back, cue segmental descent.
1. 在向上卷起时，一手轻托练习者骶骨，引导其向天花板方向滚动。2. 在肩倒立位，双手轻扶其髋部两侧，帮助感知对齐与稳定。3. 在下放时，手指轻触其下背部，提示逐节下落。
PROGRESSION 进阶
1. In shoulder stand, perform scissors, open/close, or circles. 2. Keep arms overhead without touching floor throughout.
1. 在肩倒立位进行双腿的剪刀、开合或画圈动作。2. 手臂举过头且不触碰地面完成动作。
REGRESSION 退阶
1. Start with legs slightly bent for roll over/back. 2. Lift legs to tabletop first, then straighten to ceiling. 3. Place blanket under shoulders to protect neck.
1. 双腿微曲开始往后卷起与卷下。2. 先将腿抬起到桌面姿势，再往天花板伸直，而非直接抬起。3. 在肩胛下方垫毯子以保护颈部。
COMMON ERRORS 常见错误
Using too much momentum; overusing arms/shoulders; toes touching floor in shoulder stand; neck hyperextension; trunk collapse; rolling up instead of back.
使用太多惯性冲力；手臂与肩膀过度用力；在肩支撑位置脚趾着地；颈部超伸；躯干塌陷；向上卷而非向后卷。
PRECAUTIONS 注意事项
Avoid for hypertension, glaucoma, retinopathy; contraindicated for neck injury/discomfort, osteoporosis, acute disc herniation, severe GERD; advise caution or avoid during menstruation.
高血压、青光眼、视网膜病变患者避免；颈部受伤或不适、骨质疏松、椎间盘突出急性期、严重胃食道反流者禁忌；经期女性建议避免或谨慎。
