Although there are many different types of rugby balls available, there are certain characteristics that all balls share. These characteristics include size, shape and panels. Let's review the most important aspects about rugby balls. These characteristics make rugby balls more durable and more resilient to injury. Learn more about the different types and benefits of each type of rugby ball.
Origins
The original material for the rugby ball, first used in 1823 was pig bladders. These were nonsterile and could pose a health risk for humans. The ball shape became more oval over time. This was the beginning for rugby ball standardization.
Shape
The shape of a rugby ball can be attributed to several factors, including the materials used to make them, how they are inflated, and how much energy they require to roll. Originaly, the rugby ball was made from a pig bladder. It was then covered with leather and stitched to secure it. Inflating the balls required players to use their lungs, which can lead to respiratory problems. The size of the bladder also affected the shape, making each ball different.
Size
There are two standard sizes of rugby balls. The rugby league ball is slightly larger than the rugby union one. The rugby league ball is larger and slightly more pointed.
Panels
Four equal-sized panels are used to cover rugby balls. The edges of the panels are joined by seams. An aperture in the seam allows for a central valve to inflate the ball. The valve attaches to a valve frame and connects to an inflatable tube that extends out from the valve to an opening in 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 are designed with raised bumps or dimples in order to be more grippable. Rugby balls can be treated with water repellent treatment depending on the manufacturer. For optimal performance, a rugby ball should weigh between 410g to 460g. The ball should have a pressure of between 9.5 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 is available as a size 3 or 4, in paquets of one to five, twenty, and in sizes three and four.
Lindon rugby ball
Richard Lindon, an English leatherworker who helped to create the modern rugby ball, is responsible for its origins. This Englishman was crucial in the development of the game and helped improve the technique of the bladder and the pump.
