There are many types of rugby balls, but there are some characteristics that all rugby balls have in common. These characteristics include size and shape as well as panels. Let's take a look at the most important features of rugby balls. These characteristics make rugby ball more durable and are more resilient to injury. Find out about the different types available for rugby balls and how they can help you.
Origins
The first rugby ball was made from pig bladders in 1823. These were unsterile and were a risk to human health. The shape of the ball eventually became more oval. This was when rugby ball standardization began.
Shape
A variety of factors affect the shape of a football, such as their materials, inflation, and how much energy they need to roll. The rugby ball was originally made from a pig bladder, which was then covered in leather and stitched up to make it secure. The process of inflating the ball required the players to use their lung power and would often lead to health issues. 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 has a slightly bigger and more pointed shape.
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
It is important to take into account the weight of a rugby bat when purchasing one. The materials used to make the ball determine its weight. Many rugby balls feature raised bumps or dimples to make them more grippable. Rugby balls can be treated with water repellent treatment depending on the manufacturer. A rugby ball should weigh between 405g and 460g to ensure optimal performance. It should also have an optimum pressure of 9.5 to 10 PSI.
Forza Zenvo ball
