There are many varieties of rugby balls. But there are some traits that all rugby balls share. These characteristics include shape, size, and panels. Let's review the most important aspects about 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 were unsterile, and could pose a threat to human health. The shape of the ball eventually became more oval. This was the beginning 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 standard for 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
Four equal-sized panels are used to cover rugby balls. The edges of the panels are joined by seams. An aperture in the seam allows for a central valve to inflate the ball. 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. The weight of the ball is determined by the materials used in its manufacture. To make them grippier, many rugby balls have bumps or dimples. 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.
Forza Zenvo ball
Forza Zenvo's rugby ball is water resistant and has superior adhesion. The ball's impressive design allows it to compete with other rugby balls on the market. It comes in sizes 3-4 and paquets of 1, 5, and 20.
Lindon rugby ball
Richard Lindon, an English leatherworker who helped to create the modern rugby ball, is responsible for its origins. This Englishman was a key contributor to the development of the game, improving the craft of the rugby bladder and air pump.
