Let's examine the most important characteristics of rugby balls. These properties make rugby balls much more durable and resistant to injury. Learn more about the different types of rugby balls and what they can do for you.
Origins
The original pig bladders that were used to make the rugby ball were made in 1823. These were unsterile and were a risk to human health. The ball's shape eventually changed to an oval. This was the beginning for rugby ball standardization.
Form
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. Inflating the balls required players to use their lungs, which can lead to respiratory problems. Every ball is unique because the size of your bladder can also affect the shape.
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
Four equal-sized panels are used to cover rugby balls. These panels are joined at the edges by seams. The central valve for inflating a rugby ball extends through an opening in the seam. 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
When purchasing a new rugby ball, you should consider the weight. The ball's material of manufacture determines 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. For best performance, the weight of a Rugby ball should range from 410g to 465g. The ball should have a pressure of between 9.5 and 10 PSI.
