背阔肌怎么了

Latissimus Dorsi

Latissimus dorsi

背部外侧常见

原图集里没有这块肌肉，这一块是按腹壁和腰背的位置补上的，可以直接点。

这块肌肉是什么

背部最大肌肉，从下胸椎腰椎和髂嵴延伸至肱骨，负责手臂向下向后拉动，构成"倒三角"轮廓。

为什么会不舒服

过度训练后延迟性酸痛；手臂长时间过顶位置；脊柱侧弯导致一侧背阔肌持续紧张。

常见不适表现

背部外侧从腋下到髋骨的大面积酸胀；弯腰或侧屈时牵拉痛；深呼吸时背外侧不适。

缓解方法

手臂过顶侧屈拉伸；泡沫轴从腋下向下滚压；游泳（背泳尤其有益）。

Latissimus dorsi

Outer back · Common

This muscle wasn’t in the original atlas. It was added along the belly and lower back, and you can tap it.

What this muscle is

The largest muscle of the back, from the lower thoracic spine, the lumbar spine, and the iliac crest to the humerus. It pulls the arm down and back, and it makes the V-shaped outline.

Why it gets uncomfortable

Delayed soreness after too much training; the arm held overhead for a long time; a side-bent spine that keeps one latissimus tight.

How it usually feels

A broad sore ache on the outer back, from the armpit to the hip bone; a pulling pain when you bend forward or to the side; discomfort on the outer back with a deep breath.

What helps

Reach overhead and side-bend. Roll a foam roller from the armpit downward. Swimming helps, backstroke in particular.
