The part of the triangular area of ​​the body and the precautions during exercise

　　What is the "triangular area"?

　The so-called "triangular area" refers to the triangle area formed by the occipital bone and the first and second cervical vertebrae, and the other two shoulder triangles formed by the butterfly bone protruding on the shoulder and back. The occipital triangle is one of the most complex joints in the human body. The movements of the head such as rotation, nodding, and shaking of the head are mainly completed by these joints; the shoulder triangle is surrounded by the deltoid muscles, and other joints in the body can only perform two movements of flexion and stretching. Due to the special ball and socket structure, the shoulder joint can perform 5 directions of movement.

　　Due to the complexity of bone and muscle structure, these three triangle areas are very easy to be injured. If you maintain a forward stance during exercise for a long time and the cervical vertebra is subjected to force for a long time, the "pod delta" will be injured; the shoulder joint structure is relatively loose, which is easy to damage the shoulder soft group due to instant muscle strain Weaving. In addition, women's chest muscles and upper back muscles are underdeveloped, and they are often troubled by anxiety, and their muscles are always in a state of tension, so the neck and upper back are more susceptible to injury.

　　However, as long as you pay a little attention during exercise, you can avoid injury to the back "triangle area" to a large extent.

　　For the "pillow triangle", fitness workers with poor cervical spine need to master the exercise time, generally the same position should not exceed 1 hour. In addition, when doing supine exercises, you can roll a towel into a roll and put it under the neck to protect the cervical spine. In addition, you should also pay attention to the protection of the cervical spine during work and do not sit for a long time. For the "shoulder triangle", it is particularly important to warm up before exercise. Before doing exercises with a large amount of exercise, the muscles and ligaments should be fully extended, and the amount of exercise should be controlled. The exercise strokes of each joint should not be too long to avoid injury.
