Find out about the different types available for rugby balls and how they can help 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The rugby ball, which was first used in 1823, was originally made of pig bladders.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 rugby ball standardization.
Shape
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. Original material for the rugby ball was a pig bladder. The bladder was covered with leather and then stitched together to keep it safe. Inflating a ball requires players to use their entire lung power. This could often cause health issues. The shape of the ball also depends on how big the bladder is. Each ball will be different.
Size
There are two types of standard size rugby balls. The rugby union ball is a slightly smaller size than the rugby league ball. The rugby league ball is slightly larger and more pointed.
Panels
Rugby balls are normally made with four equal-sized panels that form a cover. These panels are joined at their edges by seams, and a central valve for inflating the ball extends through an 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
When buying a rugby ball, it is important to consider its weight. The materials used to manufacture the ball affect its weight. Many rugby balls have raised bumps, or dimples to increase their grip. Rugby balls can be treated to resist water 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.
