Deltoid starting and ending points and functions

Deltoid starting and ending points and functions

　　We have also introduced many methods and techniques for training the deltoid muscles on the shoulder before

　　Today we will take you to understand the deltoid muscles from an anatomical perspective, understand its morphological position and function, which will better help you understand the deltoid muscles and train better!

　　Deltoid muscles

　　Position: anterior, exterior, and posterior shoulder joints

　　Model: inverted triangle, divided into three bundles

　　Starting point: lateral hemiplegia, acromion, scapula spandex

　　Stop point: humeral body deltoid muscle trotum

　　Function: The function of the deltoid muscle is mainly responsible for the movement of the shoulder joint (glycohumeral joint). Because the direction and starting and ending points of the muscle fibers are different, the anterior, middle and posterior bundle functions of the deltoid muscles will also be different

　　The anterior deltoid muscle can be used for shoulder joint flexion, internal rotation, horizontal adduction, and abduction. Exercise

　　The main function of the deltoid muscle is shoulder abduction

　　The posterior deltoid muscle can perform shoulder joint extension, external rotation, abduction, and horizontal abduction

　　We can see that the anterior, middle and posterior deltoid muscle can perform shoulder abduction exercises, while the middle deltoid muscle is only responsible for shoulder abduction. The functions of the anterior and posterior deltoid muscles are just the opposite of the antagonist muscles. There are many ways to train the deltoid muscles

　　The antagonist is most involved in the upward incline bench press, narrow distance press, support parallel bars, front flat lift, dumbbell chest clamping and other movements

　　The posterior deltoid muscles participate more in pull-ups, various rowing, pull-down, reverse birding, and straight arm downward pressing

　　The middle deltoid muscles participate most in the shoulder abduction exercises, such as lateral flat lifting

　　The best exercise for training the deltoid muscles is vertical shoulder pushing, shoulder abduction exercises, which can train the entire deltoid muscles at the same time
