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 examine the most important characteristics of rugby balls. These characteristics make rugby balls more durable and more resilient to injury. Learn more about the different types and benefits of each type of rugby ball.
Origins
The first use of the rugby ball was in 1823. It was made originally from pig bladders. These bladders were not sterilized and posed a danger to human health. The ball shape became more oval over time. This was the beginning of rugby ball standardization.
Shape
Many factors influence the shape and energy required to roll a rugby ball. 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 the ball also depends on how big the bladder is. Each ball will be different.
Size
There are two types of standard size rugby balls. The rugby league ball is slightly larger than the rugby union one. The rugby league ball is slightly larger and more pointed.
Panels
Rugby balls are normally made with four equal-sized panels that form a cover. 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 by a valve body to an inflator tub that extends from it to the aperture in the seam.
Weight
The weight of a rugby ball is an important consideration when buying one. The weight of the ball is determined by the materials used in its manufacture. Rugby balls often have raised bumps and dimples that make them easier to grip. Rugby balls can be made water-resistant or non-water resistant depending on their manufacturer. For optimal performance, a rugby ball should weigh between 410g to 460g. The ideal pressure should be between 9.5 to 10 PSI.
Forza Zenvo ball
FORZA Zenvo has water resistance skin and excellent adhesion. This rugby ball can be compared to other brands on the market due to its outstanding design. It is available in sizes 3 and 4 and in paquets of 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. He was an Englishman who contributed greatly to the development and improvement of the air pump and rugby bladder.
