Warm up and do some activities before exercise
The human cervical spine consists of 7 cones, maintaining a forward physiological bend.
Each cervical vertebra is adjacent to the upper and lower vertebrae to form three joints, namely the joint formed by the intervertebral disc connection and the convex joints on both sides.
There are 21 joints in a cervical spine that is only 15 cm long. This physiological feature determines the mobility of cervical spine fractures, and it is also very easy to sprain.
In this 15-cm correction joint, if there is a problem in one joint, it will cause great discomfort to the entire upper part.
Each of the 7 pyramids has its own functional characteristics.
The first and second segments of the cervical spine control the left and right rotation of the head.
When all the joints overlap, bend your head backwards and relax forward.
The physiological structure of the head is not suitable for torsion because rotation alignment and unnatural pressure will lead to early degradation over time, rigidity of the intervertebral joints, twisting sprains, and even disc herniation.
Suggestion: During the warm-up phase, our head only needs to move on 3 interfaces, bend forward and backward, bend sideways, and rotate left and right. Try not to overlap the two interfaces during the exercise.
Also, doing temporary activities every time you warm up is extra, it only increases the chance of joint injuries.
