There are many styles of rugby ball, but they all have some common traits. These characteristics are size, shape, or panels. Let's examine the most important characteristics of rugby balls. These characteristics make rugby ball more durable and are more resilient to injury. Learn more about the different types of rugby balls and what they can do for you.
Origins
The first rugby ball was made from pig bladders in 1823. These were unsterile, and could pose a threat to human health. The ball was eventually made more oval. This was when rugby ball standardization began.
Shape
Many factors influence the shape and energy required to roll a rugby ball. The rugby ball was originally made from a pig bladder, which was then covered in leather and stitched up to make it secure. Inflating the rugby ball required the players' lung power. It could also cause serious health issues. Each ball is different because of the size of the bladder.
Size
There are two standard sizes of rugby balls. The rugby union balls are slightly smaller than the rugby league balls. The rugby league ball is larger and slightly more pointed.
Panels
The covers for rugby balls usually consist of four panels equal in size. The seams join the panels together at their edges. A central valve is used to inflate the ball through an aperture in one of these seams. The valve is attached and connected to a body. An inflator tube extends from the valve into the seam.
Weight
When purchasing a new rugby ball, you should consider the weight. The materials used to manufacture the ball affect its weight. Rugby balls often have raised bumps and dimples that make them easier to grip. Rugby balls can be treated to resist water depending on the manufacturer. A rugby ball should have a weight between 410g & 460g to achieve optimal performance. The ball should be at an optimal pressure of between 9 and 10 PSI.
Forza Zenvo ball
The FORZA Zenvo rugby ball has a water resistant skin and superior adherence. With its impressive design, it can compete with any other rugby ball in the market. It comes in sizes 3-4 and paquets of 1, 5, and 20.
Lindon rugby balls
The modern rugby ball owes its history to an English leatherworker named Richard Lindon. This Englishman was crucial in the development of the game and helped improve the technique of the bladder and the pump.
