Most sports fields are north-south oriented. Will it be good for athletes?

In fact, it is said that this is related to the movement of the earth, so the direction of the sports ground will be set as north and south. Many people think it has something to do with the sun, because people who exercise on the sports ground must hate seeing the direct sunlight, so considering this factor, people will set the venue in the north and south, not in the east and west, which I think is also reasonable. ?

According to the principle of rotation and revolution of the earth, before noon 12, the sun shines from the east to the west of the sports field; 12 After noon, the sun shines from the west to the east of the playground, which is the "side light" for athletes to run from north to south or from south to north, so as to avoid direct sunlight to human eyes.

If the sports field is east-west, the sunlight will dazzle people in the morning or afternoon due to direct or reflection, which will inevitably affect the training or competition of athletes and the referees working on the field. Therefore, when designing and building sports fields at home and abroad, the longitudinal axis of the action field will follow the north-south direction.

Moreover, some people think that this is also related to the geomagnetic field, because if it is in the east-west direction, our human body will do something similar to cutting magnetic lines in the magnetic field during exercise, so people may encounter some resistance during running, which will have a certain impact on the state of athletes.

Therefore, people think that if the stadium is located in the north-south direction, it will also reduce this resistance as much as possible, so as to maximize the athletes' state and make their grades better and play a better level.

So when we observe, we will find that some famous stadiums in the world are actually in the north-south direction. At present, there are quite a few stadiums in many cities in China, which do not meet the requirements in terms of "direction" Such venues can neither be used as international competition venues nor be suitable for holding regular large-scale sports competitions.
