Two Main Function of Latissimus Dorsi Muscle

Synergistic muscles involved in latissimus dorsi pulls include the brachialis, brachioradialis, biceps brachii, teres major, rhomboids levator scapulae, lower trapezius, pectoralis major sternal, and pectoris kid (Dovey, 2002).

The latissimus dorsi has two main functions: to pull the arms to the positions of the tree form from out-to-the side position (adduction) and pulling the arms down from a plane position straight out in front of the body (extension) (Gamboa, 2002; Parsons, 2005). The latissimus dorsi is aided in these two movements by the teres major, which has its strain on the lower edge of the scapulae above the latissimus dorsi and its insertion on the head of the humerus is in virtually the same position as the insertio

During the stance, the trunk muscles must stabilize the spine so the back provide not flex forward as the shoulder extends (Brandon, 2005). The abdominal, oblique, erector spinae and gluteal muscles keep the lumbar spine in a so-so(p) position during latissimus dorsi pulls. The lower trapezius is active with the latissimus dorsi during the pull-down movement to manipulate the scapula is controlled correctly. In the preparatory phase, the latissimus dorsi will contract, and in the convalescence phase, it will return to its normal length.
