Starting and ending points and functions of trapezoidal muscles

The starting and ending points and functions of trapezoid muscles

In back muscle training, trapezoid muscles play an important role. Compared with lats dorsi, it will make your back wider, trapezoid muscles determine the thickness of your back

In trapezoid muscle training, we need to take into account comprehensively. Trapezoid muscles are a relatively large muscle that extends from our neck down to the middle back

Today we will take you to understand trapezoid muscles and understand its morphological position from an anatomical perspective The positioning and function will help you understand trapezoidal muscles and train better!

Position: The upper surface of the neck and upper dorsal

Model: One side is triangular flat muscles, and both sides are rhombic muscles

Starting point: 1/3 of the clavicle, acromion, scapula sprain

From the anatomical diagram, according to the direction of muscle fibers, the trapezoidal muscles can be divided into upper, middle and lower parts The functions of the three parts will be different

The upper part of trapezoid muscle: retraction, lifting up, rotating the scapula, flexing, laterally flexing, and circling the neck

Middle trapezoid muscle: retraction back, sinking, and circling the scapula

The lower part of trapezoid muscle: retraction back, sinking, and circling the scapula

The upper, middle and lower parts of trapezoid muscle can perform the back retraction of the scapula, the upper and lower parts of trapezoid muscle can be rotated upward, while the middle part of trapezoid muscle can only perform The movement of scapula retraction

How to train trapezoids?

The classic movement of training the upper part of trapezoids is the pushing movement of shrugging and lifting over the head. Pay attention to the movement of lifting and rotating the scapula upward

The best movement in the middle of trapezoids is the movement of retraction, such as various horizontal pulling movements

The best movement in training the lower part of trapezoids includes sinking the scapula, such as pull-ups, pull-ups, etc.
