Football is one of the sports we are most familiar with, so how many acres is the area of a football field? The football pitch must be rectangular, 90-120 meters long, 45-90 meters wide, 2.44 meters high and 7.32 meters wide. Its minimum area is 6.075 acres, and the largest is 16.2 acres. When it comes to football stadiums, we have to mention the turf on football fields. The entire football stadium is covered in turf and its price is not cheap.
The turf used in football stadiums is generally artificial turf, which has many advantages over natural turf, especially in the later maintenance. Artificial grass has excellent elasticity and a true grass feel, and artificial grass has a sporty intensity tolerance unmatched by natural lawns. Artificial turf does not need to be pruned and renovated, and it is much more convenient to clean and maintain the site in the later stages.
If you're an attentive person, you'll find an amazing common denominator: the football pitches are all north-south oriented. Is this a coincidence? This is not the case. There is a scientific point here.
First of all, it has to do with direct sunlight. Everyone knows that before 12 o'clock at noon, the sunlight shines directly from east to west, and after 12 o'clock the sunlight shines directly from west to east. If the sports field is oriented east-west, then the direct sunlight or reflection in the morning or afternoon will make people dizzy, which is bound to affect the training of athletes, competitions and referees on the field. Therefore, when designing and building a sports field, the designer always considers trying to avoid the unfavorable factors caused by direct sunlight or reflection, and the longitudinal axis of the sports field follows the north-south direction.
Secondly, the football fields are uniformly built into a north-south orientation, which can also avoid the unsuitable situation of the athletes. After all, professional athletes usually do a lot of practice. During this long period of time, it is possible to get used to the orientation of the sports field. If the orientation of the venue changes when participating in the competition, it may affect the performance of the athlete. In addition, for the audience, there are some people (standing on the north side) whose eyes will not have to face the sun directly. It can be seen from this that many conventional practices cannot be changed arbitrarily, and there are deep scientific truths in them. Therefore, the competition is held in a sports field facing north and south, which not only meets the needs of athletes, but also takes care of the feelings of the audience. The sports field designed in this way is particularly reasonable.
On the track of the stadium, we will find that athletes always run counterclockwise around the track, do you know what the scientific basis for this?
The International Federation of Athletics Competitions, which was officially established in 1912, stipulates that "the direction of the race must be based on the inside of the left hand". Many scientists believe that of the two legs of a person, the left leg is the "support leg" and the right leg is the "sports leg". Run in a counterclockwise direction, the left leg can support the person's center of gravity, which is conducive to the protection of the athlete's heart and the normal play of the game skills.
