前锯肌怎么了

Serratus Anterior

Serratus anterior

胸侧肋间少见

这块肌肉是什么

沿肋骨外侧分布的锯齿状肌肉，连接肋骨与肩胛骨内侧缘，负责肩胛骨前伸和上旋，是"拳击肌"。

为什么会不舒服

前锯肌无力时其他肌肉代偿；剧烈运动（尤其跑步）时出现"岔气"；肋间不适有时与之混淆。

常见不适表现

"岔气"感（跑步时肋骨下方刺痛）；手臂上举时肋侧不适；肩胛骨出现"翼状"提示前锯肌无力。

缓解方法

"岔气"应对：放慢速度，深呼气同时按压痛处；腹式呼吸训练；俯卧撑Plus动作；如翼状肩胛明显需就医检查。

Serratus anterior

Side of the ribcage · Uncommon

What this muscle is

A serrated muscle along the outside of the ribs, joining the ribs to the inner border of the shoulder blade. It draws the shoulder blade forward and helps it rotate upward. It is the "boxer's muscle."

Why it gets uncomfortable

Other muscles fill in when serratus is weak; a "stitch" in hard effort, especially running; discomfort between the ribs is sometimes confused with it.

How it usually feels

A "stitch" (a stab under the ribs while running); discomfort on the side of the ribs when the arm goes up; a winging shoulder blade points to a weak serratus.

What helps

For a stitch: slow down, breathe out hard, and press the sore spot at the same time. Practice belly breathing. Push-up plus. If the shoulder blade wings clearly, see a doctor.
