The causes are more likely to be spinal cord compression and spinal nerve reverse radiation headache. Before training barbell squats, you should confirm whether you have mild cervical spondylosis. If so, I suggest that people with mild cervical spondylosis should not practice barbell squats from the beginning. Or if the trainer is a long-term desk worker and has no training foundation, I don't recommend doing barbell squats when coming up. Many patients with cervical vertebrae will have headaches due to improper neck force. After removing the improper factors of exertion, the headache will be obviously relieved. Specific reasons and countermeasures:

1. When squatting, the barbell bar compresses the seventh cervical vertebra-carina. Because there is no training foundation, the trapezius muscle of the back is underdeveloped, and the buffering function of the muscle is very weak, which will directly compress the carina and affect the nerves in the cone hole.

Coping methods:

(1) Train the trapezius muscle to a certain extent, and then train it after you feel the muscle cushion.

(2) Add a foam pad in the middle of the barbell bar.

2, cervical pressure type.

When the human body completes the barbell squat, the neck should be pushed back slightly to keep the barbell bar balanced. Mainly the sternocleidomastoid muscle, the upper bundle of trapezius muscle and the clamping muscle are dynamic muscles. Because the cervical joint will move slightly when exerting force, it is more important to exert force on deep muscles at this time. If you are an office worker, the neck flexors are generally ok, and the neck extensors are weak, especially the clamping muscles. Once the neck needs to be pushed back, the cervical spine will have adverse reactions, leading to headaches. Coping methods: static neck muscle group training, especially deep muscle training. Let the deep muscles better protect the cervical spine during training.

3. It is suggested that newcomers start with freehand squats and dumbbell squats. If you are a desk worker, it is recommended to adopt a training method with low pressure on the neck and spine; At the same time, increase muscle function training that has protective effect on cervical vertebra, thoracic vertebra and lumbar vertebra, especially don't ignore the protective effect of deep muscles, which are closer to your spine and have more direct protective effect. When these muscles are strong enough to cope with all kinds of complex training functions, everything will be easy.
