Latissimus Dorsi


ThoracoLumbar Fascia- {Erector Spinae group} {Iliopsoas} {Quadratus Lumborum}

See also {Erector Spinae group} {Iliopsoas} {Quadratus Lumborum}

The thoracolumbar fascia is a deed, thick, membrane which covers the deep muscles of the back in the Thoracic and Lumbar regions. In the Thoracic region it is a thin fibrous lamina which serves to hold together the Extensor muscles of the vertebral column and to separate them from the muscles connecting the vertebral column to the upper extremity. There are two muscles that

Action: The brachioradialis flexes the forearm at the elbow and pronation and supination of the wrist and forearm. It also assists in flexion with the Biceps Brachii and Brachialis. If you perform hammer db curls, it engages the Brachioradialis muscle. If over trained or inflamed, it becomes difficult to wash your hair and spasms at the sight of the muscle when flexing the biceps and is very tender to the touch. The pain usually stay local to the muscle.

RX: Ice the area of pain and inflammation, take anti-inflammatory, rest.

Back Movements

Back Movements.

When we talk about back movements in weight lifting, we are mostly referring to the Latissimus Dorsi muscle because it’s the largest and most visible muscle of all the back muscles. It is the Major Muscle Involved (MMI) and most exercises are focused on the Lats.  The other back muscles like the Rhomboids, Erector Spinae, Quadratus Lumborum  are active with these movements, but are not MMI’s. They are mostly aiding and guiding muscles and actually get worked indirectly. Refer to Latissimus Dorsi-Quadratus Lumborum  & Rhomboids / Erector Spinae for full details on these muscles including their attachments and actions.
