There are many styles of rugby ball, but they all have some common traits. These characteristics include shape, size, and panels. Let's take a look at the most important features 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 were nonsterile and could pose a health risk for humans. The shape of the ball eventually became more oval. This was when rugby ball standardization began.
Shape
The shape of a rugby ball can be attributed to several factors, including the materials used to make them, how they are inflated, and how much energy they require 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 the ball required players to use their lung power, which could lead to serious health problems. The shape of each ball depends on the size and shape of the bladder.
Size
There are two sizes for rugby balls. The rugby league ball is slightly larger than the rugby union one. The rugby league balls are slightly larger and have a more pointed tip.
Panels
The covers for rugby balls usually consist of four panels equal in size. 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 attaches to a valve frame and connects to an inflatable tube that extends out from the valve to an opening in the seam.
Weight
A rugby ball's weight is an important aspect to consider when buying one. The materials used to make the ball determine its weight. Many rugby balls are designed with raised bumps or dimples in order to be more grippable. Rugby balls may also be treated with water resistance 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 has water resistance skin and excellent adhesion. Its unique design makes it a formidable competitor to any other rugby ball on the market. It is available as a size 3 or 4, in paquets of one to five, twenty, and in sizes three and four.
Lindon rugby ball
Richard Lindon (an English leatherworker) is the person who gave rise to the modern rugby ball. This Englishman was a major contributor to the game's development, as he improved the design of the rugby bladder & air pump.
