Let's examine the most important characteristics of rugby balls. These characteristics make rugby ball more durable and are more resilient to injury. Learn more about the different types and benefits of each type of rugby ball.
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The rugby ball, which was first used in 1823, was originally made of pig bladders.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 shape of the ball eventually became more oval. This was the beginning for 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 sizes standard for rugby balls. The rugby union balls are slightly smaller than the rugby league balls. The rugby league ball is slightly larger and more pointed.
Panels
The covers for rugby balls usually consist of four panels equal in size. The seams join the panels together at their edges. A central valve is used to inflate the ball through an aperture in one of these seams. The valve is attached and connected to a body. An inflator tube extends from the valve into the seam.
Weight
When buying a rugby ball, it is important to consider its weight. Materials used in the manufacture of the ball will determine the ball's weight. Many rugby balls have raised bumps, or dimples to increase their grip. Rugby balls may also be treated with water resistance depending on the manufacturer. The weight of a rugby ball should be between 410g and 460g for optimal performance. It should also be able to withstand pressures of 9.5-10 PSI.
