Hi all.

The ball was ordered in a clubbing, and I am writing a review))
For those who are interested in reading about this ball, please under the cat
And so, we love to get together with friends and play football in the snow, it also happens in the summer, but not so often, everyone has things to do, dachas, etc.
In the summer there are all sorts of tournaments from the factory where we work, but they give us balls there.
And so we decided to order some bright ball for the winter, so that it can be clearly seen in the snow and stand out.
Having climbed through the Chinese expanses, I found this ball, googling, I realized that this company produces sports equipment, and is very well known.
I told the guys what, how much and how, they chipped in and ordered, it came out from one person for 130 rubles. generally a penny.
Well, the delivery turned out to be about 20 days. 
Everything is fine, and not for long.
I came here in such a package.
And inside lay our ball in a deflated state, in a plastic bag.
The seller could at least put a needle for the pump as a gift, but what if I didn’t have it.
Well, in general, I first pumped the ball up to the maximum pressure, even a little more.
Claimed 8 LBS. This is 3.6 kg, or 0.36 MPa, whichever is more convenient for you.
So it's impossible to hit the ball, it's very hard. It seems that you hit normally, but he does not fly))) Well, as is usually the case with pumped balls.
We lower the ball to 7.3 LBS. This is approximately 3.3 kg. Here, more or less.
It became much easier to hit, the ball flies without changing its trajectory, it does not blow away with the wind, in general, the flight is normal.
I thought I would pump to such a state until the folds are straightened out. Yeah, 4kg, and the folds are still there.
The next day, the wrinkles have already become noticeably smaller, I think in a week, another will completely disappear.
In the following photos you can see the quality of the firmware of this ball.
I don’t really understand them, although I have been fond of football for a long time.
I judge by quality only after a few years nothing came off, then the ball is good, and if it lasts for a season or two, then it’s full g ...
In my opinion, this ball will live this time. Outplayed many balls in my life
when we went to football in childhood, there were mostly selects, some friends bought good replica balls, I remember they even had Replica written on them, that is, as I understand it, there was an official replica of balls from the World Cup and the European Championship. 
The nipple sits in a small depression, does not stick out and does not interfere.
The pressure recommended for the game is also written around the nipple. This is 6 to 8 LBS, this is 2.7 - 3.6 kg
And that it is made in China. 
There are inconsistencies in the drawing on the ball, but I didn’t even pay attention when I unpacked it, I only saw it in the photo when I started writing the review)))
In general, this is not very important, as it were, the main thing is that it be visible in the snow, and that it flies where it was hit))))
And yes, I completely forgot, the ball consists of 32 PVC plates.
And some anti-slip plates, I understood this by the name: “against bb-slip granules” clumsy Chinese translation)))

In general, the ball turned out to be very good, and not expensive either, in adik the balls are two or three times more expensive, in the sportmaster the balls are gamble, all sorts of sportlandia, etc. selects from 2 and above.
In general, I am satisfied with the purchase, you can take it.
Few people know that soccer balls can vary greatly in diameter. But this is one of the important parameters on which the purpose of the ball will depend. Before you go to the store, you should find out what sizes of soccer balls are.
History
Balls have been man's favorite toy for centuries. They have come to us from ancient times.
Some peoples treated the ball with special respect. For example, the ancient Greeks considered it an ideal subject, since it resembled the sun in shape, which means it had magical powers.
When excavating the tombs of the Egyptian pharaohs, it turned out that the ball was not only depicted on the walls, but was also present in the burials.
Revered the ball and the Indians North America. They personified him with the moon and the sun. This object of perfect form was sacred to them.
Balls were made from everything that was around: from the bark of trees, reeds, skin and even hair. Inside there was also natural material: moss, bird feathers, grain, round fruits. And the Roman legionnaires, along with the ancient Chinese, made balls from the severed heads of their enemies.
Later, the ball began to be inflated with air. The first rubber ball was brought to Europe from Central America by the famous Columbus.
Since then, and to this day, the whole civilized world is familiar with the ball.
How to determine the diameter of a soccer ball
The fact is that when describing the size of balls, the circumference is usually taken into account, and not the diameter of the ball. However, a school geometry course can tell you how to find the diameter soccer ball knowing the circumference of its circumference.
To do this, the circumference must be divided by the number Pi, that is, approximately 3.14. Practice shows that the actual measurements of the diameter of a soccer ball and the calculated ones are the same.
So, according to FIFA rules, the circumference of the balls should be 68.57 centimeters, and the diameter should be 21.8 centimeters according to measurements. If we calculate the diameter of a ball with a circumference of 68.57 cm, we get 21.8 cm.
There are many interesting logic puzzles on the Internet with the question of what is the diameter of a soccer ball. For example, puzzle lovers are invited to determine the diameter of the ball, having only a wooden ruler in their arsenal.

Along with the named sizes, lightweight balls are also used. They may be for women and children. With the above diameter and circumference, the mass of such a ball will be less than officially accepted.
A soccer ball is also needed for holding training sessions, and for match meetings at the professional and amateur level. For a spectacular and effective game of football, you need not just a round projectile - only sports equipment from branded manufacturers will allow both football players and fans to enjoy the game.

At the beginning of the 19th century, the inhabitants of England, who are directly the ancestors of football, adopted a certain standard of balls used to play football. It was developed by the English Football Association. What are the characteristics of the ball? Its standard length is 67-71 cm, weight varies from 368 to 425 grams. Surprisingly, the parameters of the circumference have been preserved to the present, but the weight characteristic has undergone changes. The mass of the ball has increased significantly since 1937: by standards from 410 to 425 grams, and since then it has not changed.
In the old days, people also played games similar to the football of our time. The skull of a person or animal then acted as a ball. It was pre-fitted with leather or the bladders of various large animals, such as cows or pigs, were used.
Since the 1970s, balls of the same brand, Adidas, have been increasingly used to play at the World Cup. Interestingly, by the beginning of any world football championship, Adidas was improving and creating a new appearance their balls.
Geographically, a large number of balls are produced in Pakistan. At the same time, the main production is concentrated in one city - Sialkot.
Unusual is the fact that the balls for official games at the World Cup get their unique name. Moreover, this name was not taken from nowhere, it correlates with the life and features of the country where the Championship is held. For example, for a football forum held in Mexico in the 80s of the 20th century, the Adidas sports company developed a ball, which was named Azteca. On the black parts of this ball, there are patterns of the well-known Aztecs. And in Italy, at a World Cup match held in the 90s, the players played with the ball, which was called "EtruscoUnico", which translates as "Etruscan Lions". In addition to the images of the heads of those Etruscan lions, they contained a mention of the people of antiquity - the Etruscans, who at one time were located on the territory of Italy.
In addition to the mass and circumference of a soccer ball, the rules of the game, which have already been approved, also define what the ball is made of, its atmospheric pressure, color, and even, oddly enough, its shape.
A survey was conducted among football players, and, in their opinion, the best choice there will be a purchase of UMBRO brand footballs for playing football. Famous football players, world stars of the game and even FIFA experts adhere to the same opinion.
Let's talk about what soccer balls are.
In 1855, the first soccer ball was produced. Its creator was Charles Goodyear. At that time, rubber served as its material. The use of rubber as a material significantly strengthened the ball and increased the rebound characteristics. In the early 1960s, all-synthetic material began to be used to make balls. Then there were balls made of leather shell, but in the late 80s they were replaced by balls made of synthetics. This is due to lower cost, greater softness of the soccer ball and moisture resistant characteristics. Now balls are made from genuine leather or other materials suitable for certain parameters.
According to geometric features, balls come in sizes:
- 1st. They have 32 parts. The length of their roundness is not more than 43 cm.
- 2nd. It consists of 26 or 32 parts. The length of its roundness is 56 cm, and the mass is not more than 283 grams.
- 3rd. It consists of 32 parts, weight - no more than 340 grams, and the length of the roundness is no more than 61 cm.
- 4th. It is this size that is the standard for futsal competitions. The weight of the ball varies from 369 to 425 g, and the length of the roundness is from 63.5 to 66 cm.
- 5th. These balls are used in all FIFA World Cups. The length of their circumference varies from 68 to 70 cm, and their weight is no more than 450 g.
According to the international standard, the characteristics of the ball are as follows:
- the ball is made of leather or similar material suitable for playing football;
- the length of the roundness of the ball is standard - from 68 to 70 cm;
- the mass of the ball has also not changed in recent decades and varies from 410 to 450 g;
- during the game, the pressure of the ball must be at least 0.6 atmospheres and not more than 1.1 atmospheres;
- according to the standards, the ball participating in the championship must be 5 sizes.
The FIFA rules, which apply to all football, spell out strict oversight of quality control. In this system, it is established that all balls used under the FIFA mark and participating in competitions must be marked with special signs “FIFA INSPECTED” or “FIFA APPROVED”. In order for the ball to earn such a quality mark, balls from brands such as UMBRO, Adidas, etc., are subjected to many tests. These tests consist of checking the weight of the ball, checking the length of its roundness, moisture resistance, controlling the ball's rebound and its ability to hold pressure.
For playing basketball, choose the ball wisely. This item is the main thing you need on the basketball court.
It seems that all the balls are the same: round, tightly inflated, orange in color, with black stripes. However, they vary in size.
It's all about Who is the sports equipment for?
Sizes of basketballs: numbers 3, 5, 6, 7. Which ones do not exist?
Basketball accessories, although they look the same, but have a gradation in diameter and weight.
This is due to the fact that different teams play balls of different sizes: men's, women's, children's and mini-basketball teams.
The smallest are used for dribbling practice players.
Issued in four variants: these are sizes with numbers 7, 6, 5 and 3. There are no other sizes.
- Seven: diameter - 749-780 mm, weight 567-650 g.
- Six: 724-737 mm, 510-567 g.
- Five: 690-710 mm, 470-500 g.
- Three: 560-580 mm, 300-330 g.
Standard and large diameter
"Sevens"- the largest of the officially accepted. However, accessories are also standard, according to FIBA. sixth size(with such slightly smaller shells they play women's teams).
Dependence on the age of the player
When it comes to young basketball players, then with big and heavy balls it's too early for them to work. It is too difficult to hold an “adult” object in small palms, and even throw a weighty projectile to the basket - problem. For them, the best option is smaller and lighter.
How do children play basketball?
Size basketballs are suitable for children 5 : such children's teams play in competitions by age up to 12 years. Besides, "fives" use when competing in mini-basketball.
Photo 1. A boy holds a basketball in his hand of the correct size for him under the guidance of a coach.
If the athlete is very small, a beginner, then for the first single training sessions they occasionally take "threes".
Which is suitable for men?
Men play with big and heavy balls - "sevens". The standard of such a projectile is free: the difference in mass fluctuates around almost 100 grams. In other categories, this parameter is less.
Factors to consider when choosing
Choosing an accessory for basketball by size - important point, but pay attention not only to the dimensions. There are other nuances, such as if a person plays outdoors or in the gym.
Photo 2. Spalding Never Flat Indoor/Outdoor orange basketball.
For the first option on the street, choose a category outdoor, for the second - indoor. For street play, you should not buy an expensive professional ball. It is better to take cheap rubber or synthetic. This projectile is still won't last long. Street operation, blows on asphalt, dust wear out such a ball. But that's what it's designed for.
For playing in the hall, it makes sense to buy an expensive and professional attribute made of composite artificial leather. The difference is not only in price. Ball marked indoor keeps its shape well, it is more convenient to lie down in the palm of your hand, when used only in the hall, it retains its game characteristics and quality for a long time.
Important! Hall ball several times more expensive, as well as more rigid (greater risk of injury). Such sports equipment unsuitable for outdoor use as they quickly deteriorate, lose their appearance and shape from moisture, dust and other unsuitable conditions.
Other criteria and firms
If a person acquires the ball in sports shop, then you should look for it to be pumped up correctly.
This means that when you press hard with your finger, the surface is pressed through no more than half a centimeter. If it is pumped up weaker, then, perhaps, it bleeds air somewhere, and you have to pump up regularly shell.
An overly inflated ball that cannot be pushed through with a finger can quickly lose shape when it hits the floor in play.
Attention! If the projectile is ordered in an online store, then you will most likely have to pump it up yourself: for sending from balls the air is released.
Projectile rebound is also important from the surface, which is checked as follows: the object is freely thrown from shoulder height.
He should bounce to the waist: no more and no less.
If a person plans to play basketball more or less seriously (not to mention the professional level), then you should take care of acquiring decent sports equipment.
They are manufactured by companies specializing in the manufacture of basketballs. good brands Nike, Spalding, Molten, Wilson, Mikasa.
Reference! Sometimes novice players draw an analogy with leather soccer balls and want to buy a basketball accessory. from genuine leather. However, such attributes are a thing of the past. Today, synthetic materials that are durable and suitable for the specifics of this game are used.
