There are many types of rugby balls, but there are some characteristics that all rugby balls have in common. These characteristics include size, shape and panels. Let's review the most important aspects about rugby balls. These characteristics make rugby ball more durable and are more resilient to injury. Learn more about the different types and benefits of each type of rugby ball.
Origins
The rugby ball, which was first used in 1823, was originally made of pig bladders. These were unsterile, and could pose a threat to human health. The shape of the ball eventually became more oval. This was the beginning to standardize rugby ball shape.
Shape
A number of factors can influence the shape of a rugbyball, such as how they are made, inflated, and how much energy it requires to roll. To make the rugby ball secure, it was first made of a pig bladder. The process of inflating the ball required the players to use their lung power and would often lead to health issues. Every ball is unique because the size of your bladder can also affect the shape.
Size
There are two sizes of rugby balls. The rugby union ball has a smaller size than the rugby club ball. The rugby league ball is larger and slightly more pointed.
Panels
Rugby balls are normally made with four equal-sized panels that form a cover. These panels are joined at their edges by seams, and a central valve for inflating the ball extends through an aperture in the seam. The valve body is attached to the valve and an inflator tube is connected from the valve mouth to the seam.
Weight
A rugby ball's weight is an important aspect to consider when buying one. Materials used in the manufacture of the ball will determine the ball's weight. Many rugby balls feature raised bumps or dimples to make them more grippable. Rugby balls can be treated with water repellent treatment depending on the manufacturer. For best performance, the weight of a Rugby ball should range from 410g to 465g. The ball should have a pressure of between 9.5 and 10 PSI.
Forza Zenvo ball
FORZA Zenvo is water-resistant and offers superior adhesion. Its unique design makes it a formidable competitor to any other rugby ball on the market. It is available in sizes 3 and 4 and in paquets of one, five, and twenty.
Lindon rugby balls
Richard Lindon, an English leatherworker who helped to create the modern rugby ball, is responsible for its origins. This Englishman was a major contributor to the game's development, as he improved the design of the rugby bladder & air pump.
