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 examine the most important characteristics of rugby balls. These attributes make rugby balls more durable, and less likely to sustain injury. Find out what the different kinds of rugby balls can do for your game.
Origins
The original material for the rugby ball, first used in 1823 was pig bladders. These bladders could be unsterile and pose a danger to the human health. The ball was eventually made more oval. This was the beginning of rugby ball standardization.
Shape
A variety of factors affect the shape of a football, such as their materials, inflation, and how much energy they need to roll. The rugby ball was originally made from a pig bladder, which was then covered in leather and stitched up to make it secure. Inflating a ball requires players to use their entire lung power. This could often cause health issues. Each ball is different because of the size of the bladder.
Size
There are two sizes standard for rugby balls. The rugby union ball is a slightly smaller size than the rugby league ball. The rugby league balls are slightly larger and have a more pointed tip.
Panels
Rugby balls are normally made with four equal-sized panels that form a cover. The seam connects the panels at the edges with seams. A central valve that inflates the ball is located through the 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. The ball's material of manufacture determines its 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 optimal performance, a rugby ball should weigh between 410g to 460g. It should also have an optimum pressure of 9.5 to 10 PSI.
Forza Zenvo ball
FORZA Zenvo has water resistance skin and excellent adhesion. With its impressive design, it can compete with any other rugby ball in the market. It is available in sizes 3 and 4 and in paquets of one, five, and twenty.
Lindon rugby ball
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.
