Starting and ending points and functions of latissimus dorsi

The starting and ending points and functions of the lats dorsi muscles

　　Latissimus dorsi muscles are the largest and most stylish muscles on our back. It is located on both sides of our back. The strong latissimus dorsi can make your back wider. From the back, it has an inverted triangle-like figure!

　　Latissimus dorsi muscles are the strongest muscles on the upper limbs. During exercise, the strong latissimus dorsi will make your athletic performance better

　Today we will take you to understand the latissimus dorsi from an anatomical perspective, understand its shape, position and function. This will better help you understand the latsimus dorsi and train better!

　　Latisimus dorsi

　　Position: Subcutaneous subcutaneous of the lumbar back

　　Model: Triangular flat (wide) muscle

　　Origin: Lower 6 thoracic vertebrae and all lumbar spinous processes, sacral medial crest, posterior part of the iliac crest and lateral side of the lower 3 ribs

　　Stop point: humeral small nodule crest

　　Function: proximal fixation—enlong extension, adduction, and internal rotation

　　Farther fixation—pull the trunk upward to assist inhalation, and at the same time, the spine can be performed The movement of lateral flexion and rotation

　　From the anatomical position, the latsimus dorsi is mainly responsible for shoulder movement, including shoulder extension, shoulder adduction, and shoulder internal rotation

　　So we can effectively train our latsimus dorsi in the movements that include these joint movements

　　For example: pull-ups, high-position pull-down, sitting rowing, dumbbell one-handed rowing, straight arm pull-down, etc.

　　The latis dorsi training effect of vertical pull-up and pull-down The best way to pull vertically can have a larger and longer range of motion

　　　Compared with sitting rowing, barbell and dumbbell rowing, the range of motion of latissimus dorsi is relatively small, so the training benefits of latissimus dorsi will not be as good as vertically pulling

　　In vertically pulling, the movement methods of narrow grip and wide grip are also different. The narrow distance is more about the movement mode of shoulder joint extension, while the wide distance is about the function of shoulder joint adduction.
