BENEFITS 益处
Improves multi-directional hip mobility and flexibility; enhances core stability control during dynamic single-leg movement; strengthens pelvic proprioception; coordinates hip and core联动.
改善髋关节多方向的活动度与灵活性；增强核心在单腿动态运动中的稳定控制能力；强化骨盆带的本体感觉；协调髋关节与核心的联动。
TARGET MUSCLES 目标肌群
Core muscles (transversus abdominis, multifidus, internal obliques, etc. stabilize pelvis and lumbar), hip flexors (iliopsoas, rectus femoris, etc.), hip extensors (gluteus maximus, hamstrings), hip adductors and abductors (synergistic for circling), shoulder girdle stabilizers (maintain upper limb stability).
核心肌群（腹横肌、多裂肌、腹内斜肌等维持骨盆与腰椎稳定）、髋屈肌群（髂腰肌、股直肌等）、髋伸肌群（臀大肌、腘绳肌）、髋内收肌群与外展肌群（协同完成画圈动作）、肩带稳定肌群（维持上肢稳定）。
SETUP 设置
None.
无特殊器械调节。
CUES 口令
Starting position: Supine, palms down by sides to stabilize trunk. One leg straight on floor, other leg extended toward ceiling (perpendicular or slightly toward head). Knee may be straight or slightly bent. Trunk neutral, back naturally resting on mat. Breathing/Movement: Inhale, lifted leg circles inward (across midline) for first half; Exhale, completes circle outward back to start. Perform 4-6 circles in one direction, then 4-6 in opposite direction. Repeat other leg. Keep pelvis (especially posterior superior iliac spines) and scapulae stable on mat, hips and spine neutral throughout. Imagery: Lifted leg like a paintbrush, toes painting smooth, even circles on ceiling; pelvis and trunk like a stable easel, completely still.
起始位：仰卧，双手掌心朝下放于身体两侧以稳定躯干。一腿伸直放在地板上，另一腿向天花板方向延伸（垂直于地面或略偏向头部方向）。膝盖可伸直或微屈。躯干保持中立位，感觉后背自然沉在垫上。 呼吸与动作：吸气，抬起的腿先向内（越过身体中线）画半圈；吐气，继续完成后半圈（向外回到起始点）。在同侧方向完成4-6次后，反方向再做4-6次。换腿重复。全程保持骨盆（特别是两侧髂后上棘）和肩胛骨平稳贴地，髋关节及脊椎维持中立位。 想象提示：想象抬起的腿像画笔，用脚尖在天花板上描绘出平滑、均匀的圆圈；骨盆和躯干是稳固的画板，始终保持静止。
IMAGERY 意象
Direct: Feel femoral head rotating smoothly in acetabulum, core continuously engaged to stabilize pelvis. Indirect: Like a compass, leg as the pencil, trunk as the stable axis. Space: Imagine hip joint capsule space opening evenly during circles. Feeling: Focus on stable posterior superior iliac spines on mat and the circling path of the lifted thigh.
直接：感受股骨头在髋臼中顺滑转动，同时核心持续收紧以稳定骨盆。间接：像圆规，腿是笔芯，躯干是稳固的轴心。空间：想象髋关节囊的空间在画圈时被均匀地打开。感觉：注意力放在两侧髂后上棘贴地的稳定感，以及抬高大腿根部画圈的轨迹感上。
TACTILE CUES 触觉提示
1. Lightly place hands on ASIS, cue to stay stable, avoid pelvic rock with leg circles. 2. Lightly touch root of lifted thigh, guide initiation from hip, not waist. 3. During circles, lightly touch posterior superior iliac spines, cue to stay on mat.
1. 双手轻放在练习者髂前上棘，提示其保持稳定，避免骨盆随着腿部画圈而晃动。2. 一手轻触其抬高大腿的根部，引导其从髋关节而非腰部发起运动。3. 在画圈时，手指轻触其髂后上棘，提示保持贴地。
PROGRESSION 进阶
1. Draw larger circles to increase hip range. 2. Slow down to increase core control challenge. 3. Bend bottom leg (tabletop) to reduce base of support.
1. 画更大的圈，增加髋关节活动范围。2. 放慢速度，增加核心控制的挑战。3. 下方的腿弯曲（桌面式），减少基底支撑面积。
REGRESSION 退阶
1. Draw smaller circles. 2. Slightly bend lifted knee to shorten lever, reduce control difficulty. 3. Bend bottom knee, foot on floor for more stability.
1. 画较小的圈。2. 抬高的腿微屈膝盖，缩短力臂，降低控制难度。3. 下方的腿屈膝踩地，增加稳定性。
COMMON ERRORS 常见错误
Any posterior superior iliac spine lifting off mat; lumbar extension (arching) or excessive flexion (pressing flat); posterior pelvic tilt; forcefully pressing back into mat; circle path favoring one side, not completing circle; head or arms pressing too hard into mat.
任何一侧髂后上棘翘起离开垫面；腰椎出现后仰（塌腰）或过度前屈（压平）；骨盆后倾；用力将后背压向垫子；画圈轨迹偏向一侧，未完整画圆；头部或手臂过度下压垫子。
PRECAUTIONS 注意事项
Caution or significantly modify range under professional guidance for post-hip replacement, acute hip pain, acute lumbar disc herniation.
髋关节置换术后、急性髋部疼痛、腰椎间盘突出急性期者慎做或需在专业指导下大幅调整幅度。
