There are many styles of rugby ball, but they all have some common traits. These characteristics include shape, size, and panels. Let's now look at some of these most important attributes of 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 first use of the rugby ball was in 1823. It was made originally from pig bladders. These bladders were not sterilized and posed a danger to human health. The shape of the ball eventually became more oval. This was when rugby ball standardization began.
Shape
A variety of factors affect the shape of a football, such as their materials, inflation, and how much energy they need 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. Each ball is different because of the size of the bladder.
Size
There are two standard sizes of rugby balls. The size of the rugby union ball is slightly smaller than that of the rugby league ball. The rugby league ball has a slightly bigger and more pointed shape.
Panels
Rugby balls are normally made with four equal-sized panels that form a cover. These panels are joined at the edges by seams. The central valve for inflating a rugby ball extends through an opening in the seam. 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. The ball's material of manufacture determines its 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 best performance, the weight of a Rugby ball should range from 410g to 465g. It should also have an optimum pressure of 9.5 to 10 PSI.
