There are many kinds of rugby balls. However, they all share some common characteristics. These characteristics include size, shape, and panels. Let's review the most important aspects about rugby balls. These qualities make rugby balls stronger and more resistant to injury. Find out more about the various types of rugby balls available and what they can offer you.
Origins
The rugby ball, which was first used in 1823, was originally made of pig bladders. These bladders were not sterilized and posed a danger to human health. The ball shape became more oval over time. This was the beginning of rugby ball standardization.
Form
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. Originaly made from a bladder of pig, the ball was covered in leather and then stitched up to ensure its security. Inflating the rugby ball required the players' lung power. It could also cause serious health issues. The size of the bladder also affected the shape, making each ball different.
Size
There are two standard sizes of rugby balls. The rugby union balls are slightly smaller than the rugby league balls. The rugby union ball is slightly larger, and slightly more pointed.
Panels
The covers for rugby balls usually consist of four panels equal in size. 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 is attached to a valve body and is connected to an inflator tube that extends from the valve to an aperture in the seam.
Weight
A rugby ball's weight is an important aspect to consider when buying one. The materials used to make the ball determine its weight. Rugby balls often have raised bumps and dimples that make them easier to grip. Depending on the manufacturer, rugby balls can also be treated to be water resistant. 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.
