There are many types of rugby balls, but there are some characteristics that all rugby balls have in common. These characteristics are size, shape, or 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 first use of the rugby ball was in 1823. It was made originally from pig bladders. These bladders could be unsterile and pose a danger to the human health. Later, the shape of the ball became more oval. This was the beginning for rugby ball standardization.
Shape
There are many factors that influence the shape of a Rugby ball, including how they are made, inflated, and how energetic they need to roll. Originaly made from a bladder of pig, the ball was covered in leather and then stitched up to ensure its security. The process of inflating the ball required the players to use their lung power and would often lead to health issues. Each ball is different because of the size of the bladder.
Size
There are two sizes of 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
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 attaches to a valve frame and connects to an inflatable tube that extends out from the valve to an opening in 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 are designed with raised bumps or dimples in order to be more grippable. Depending on the manufacturer, rugby balls can also be treated to be water resistant. The weight of a rugby ball should be between 410g and 460g for optimal performance. The ideal pressure should be between 9.5 to 10 PSI.
