Tightness in the latissimus dorsi can contribute to chronic shoulder and back pain. The latissimus dorsi is a large, powerful muscle with a vital role in shoulder movement and core stability. The function of the latissimus dorsi is to extend, adduct, and medially rotate the humerus. Its expansive coverage stretches from left to right across the back, with the upper portion partially hidden by the trapezius muscle in the medial dorsal region. Jun 3, 2025 · The latissimus dorsi is a climbing, rowing, and swimming muscle The latissimus dorsi, commonly known as the "lats", is a large, flat muscle on the back that stretches to the sides, behind the arm. This occurs when the upper limbs, such as when climbing or performing a pull-up, are extended overhead. Through its insertion point at the proximal humerus, the muscle works with the teres and pectoralis major to adduct, extend, and medially rotate the arm at the glenohumeral joint. To assess the muscle length of the latissimus dorsi, the clinician will grasp the distal humerus of the rock climber, and they will monitor the rib and the lumbar position into end range humeral flexion. The latissimus dorsi muscles are essential for stabilising the back and extending the shoulders, enabling movements such as pull-ups, vertical climbing, and swimming. Functionally The latissimus dorsi is a large, flat muscle that occupies a substantial area of the torso’s posterior, spanning from the lower back to the humerus. An injury to this muscle can cause several unpleasant effects throughout the upper body Origin: Spinous processes of inferior 6 thoracic vertebrae, thoracolumbar fascia, iliac crest, and inferior 3 or 4 ribs Insertion: Floor of intertubercular groove of humerus Action: Extends, adducts, and medially rotates humerus; raises body toward arms during climbing Innervation: Thoracodorsal nerve (C6, C7, and C8) Arterial Supply: Thoracodorsal artery The medical illustrations contained in Jun 25, 2025 · The latissimus dorsi is active in climbing, rowing, and swimming movements. It is an important muscle in rowing, swimming (especially during the downstroke) and chopping. Learn about its function and common issues.
