An imaginary line can be used to divide the body into two parts to better understand the motion above the coronal plane. Any movement parallel to this straight line occurs in this plane, usually including abduction of shoulder or hip joint. Then there are the specific movements in sports, such as standing birds, overhead movements, body load-bearing lateral flexion and so on.
2. Sagittal plane
Imagine a line dividing the body into left and right parts. Any direction parallel to this line, such as back and forth movement, occurs in the sagittal plane. The movements on this plane include the flexion and extension of several main joints of the body, such as the flexion and extension of the hand, the flexion and extension of the ankle, knee and hip. Specific such as arm flexion and extension, hard pull, squat and so on.
3. Horizontal plane
Imagine that there is a straight line separating the upper and lower parts of the body, and the rotation parallel to this straight line occurs on a horizontal plane. The basic movements of this plane include the rotation of the head and spine, and any inward or outward rotation of the hips and shoulders. When we make a wire clamp, the rotation of the shoulder can be regarded as the movement of the horizontal plane.

Benefits of distinguishing sports surfaces in fitness;
1, subjective feeling
If the exercise load is properly arranged, the subjective feeling of the exerciser should be energetic, energetic, comfortable and eager to exercise.
2. Sweat amount
When the exercise load is appropriate, the human body may sweat slightly or moderately. If the load is too large and the body is too tired, the exerciser will sweat and get soaked. Of course, the amount of perspiration depends on temperature, air pressure, wind speed and water consumption.
3. Emotion
Emotion is a "barometer" of people's health, and it is also a subjective indicator to measure the load borne by the human body. Generally speaking, the human body has the need for exercise, and when this need is met, people will have a pleasant emotional experience.
4, appetite
In the process of physical exercise, the human body consumes a lot of energy. Generally speaking, if the physiological reaction is normal and the body is healthy after exercise, people's appetite will be strong and their food intake will increase.
5. Sleep state
If the physical exercise load is appropriate, you should generally sleep well, sleep deeply, dream less, feel energetic after waking up, and be in a good state of work and stress.
