There are many types of rugby balls, but there are some characteristics that all rugby balls have in common. These characteristics include shape, size, and panels. Let's look at some of the most important aspects of rugby balls. These properties make rugby balls much more durable and resistant to 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 when rugby ball standardization began.
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. Originaly made from a bladder of pig, the ball was covered in leather and then stitched up to ensure its security. Inflating the balls required players to use their lungs, which can lead to respiratory problems. The shape of each ball depends on the size and shape of the bladder.
Size
There are two standard sizes of rugby balls. The rugby union ball has a smaller size than the rugby club ball. The rugby league ball is larger and slightly 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 to a valve body and is connected to an inflator tube that extends from the valve to an aperture in the seam.
Weight
The weight of a rugby ball is an important consideration when buying one. Materials used in the manufacture of the ball will determine the ball's weight. Rugby balls often have raised bumps and dimples that make them easier to grip. Depending on the manufacturer, rugby balls can also be treated to be water resistant. A rugby ball should weigh between 405g and 460g to ensure optimal performance. The ball should be at an optimal pressure of between 9 and 10 PSI.
Forza Zenvo ball
The FORZA Zenvo rugby ball has a water resistant skin and superior adherence. This ball is able to compete with all other rugby balls in the market thanks to its unique design. It is available as a size 3 or 4, in paquets of one to five, twenty, and in sizes three and four.
Lindon rugby football ball
The modern rugby ball owes its history to an English leatherworker named Richard Lindon. This Englishman was a major contributor to the game's development, as he improved the design of the rugby bladder & air pump.
