Although there are many different types of rugby balls available, there are certain characteristics that all balls share. These characteristics include shape, size, and panels. Let's look at some of the most important aspects of rugby balls. These attributes make rugby balls more durable, and less likely to sustain injury. Learn more about the different types of rugby balls and what they can do for you.
Origins
The original material for the rugby ball, first used in 1823 was pig bladders. These were unsterile, and could pose a threat to human health. The ball's shape eventually changed to an oval. This was the beginning for rugby ball standardization.
Shape
A variety of factors affect the shape of a football, such as their materials, inflation, and how much energy they need 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. 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 types of standard size rugby balls. The rugby union ball is a slightly smaller size than the rugby league ball. The rugby union ball is slightly larger, and slightly more pointed.
Panels
Rugby balls are normally made with four equal-sized panels that form a cover. 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 to a valve body and is connected to an inflator tube that extends from the valve to an aperture in the seam.
Weight
A rugby ball's weight is an important aspect to consider when buying one. The ball's material of manufacture determines 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. A rugby ball should weigh between 405g and 460g to ensure optimal performance. It should also be able to withstand pressures of 9.5-10 PSI.
Forza Zenvo ball
FORZA Zenvo is water-resistant and offers superior adhesion. The ball's impressive design allows it to compete with other rugby balls on the market. It is available at sizes 3 and 4, as well as in paquets containing one, five and twenty.
Lindon rugby ball
Richard Lindon, an English leatherworker who helped to create the modern rugby ball, is responsible for its origins. This Englishman was crucial in the development of the game and helped improve the technique of the bladder and the pump.
