斜方肌中束怎么了

Trapezius — Middle

Middle trapezius

上背肩胛间常见

这块肌肉是什么

水平走向肌纤维，负责肩胛骨内收（向脊柱靠拢），是防止圆肩的核心肌肉。

为什么会不舒服

长期圆肩姿势使中束被过度拉长并抑制；推举训练多而拉背训练少；久坐驼背。

常见不适表现

两肩胛骨之间的酸胀感；圆肩加重时疼痛增加；"背中间疼"；深呼吸时肩胛区不适。

缓解方法

主动夹背练习：双肩向后向下，感受肩胛骨靠拢；俯身划船；改善坐姿；减少推举训练比例。

Middle trapezius

Upper back, between the shoulder blades · Common

What this muscle is

Fibers run horizontally. They draw the shoulder blades in toward the spine, and they are central to keeping the shoulders from rounding.

Why it gets uncomfortable

A long rounded-shoulder posture lengthens this part and switches it off; a lot of pressing and little pulling; sitting hunched.

How it usually feels

A sore, full feeling between the shoulder blades; more pain as the rounding gets worse; "pain in the middle of the back"; discomfort around the shoulder blades on a deep breath.

What helps

Pinch the shoulder blades on purpose: draw both shoulders back and down and feel the blades come together. Bent-over rows. Sit taller. Do less pressing relative to pulling.
