or swiss balls to be deemed anti burst, they must qualify by passing a test where they are progressively loaded, then punctured with a sharp blade. While under load the size of the cut should not expand and the ball should deflate slowly rather than burst.
Tests on the DuraBall Pro have found the product has a 500kg anti burst rating under a dynamic (moving) load. This means, if you applied a dynamic load of 500kg to the ball and it suffered a puncture of any kind, it will deflate slowly giving the user a margin of safety to prevent injury.
A few years ago, the only balls available to the public were the cheap kind that looked like a child’s toy molded into a piece of gym apparatus. Thousands of these Swiss balls were sold - you may even be the proud owner of one.
Well you’ll be happy to hear there’s nothing wrong with it, provided it doesn’t burst. When a cheap ball explodes, it does so dramatically - much like a balloon - and if you are on top of it loaded with weight, there’s a high chance you’ll get injured. Given that there is always the possibility that a cheap swiss ball could suddenly and spontaneously explode underneath you, it is strongly advised that you invest in an anti-burst swiss ball.
Just because a manufacturer says a ball is anti-burst or burst resistant, doesn’t guarantee it's safety. You need to know the safe weight range at which the swiss ball is anti burst.
The DuraBall Pro is rated at 500 kg dynamic and 2000 kg static load. It’s important to know this because some balls will claim to be anti burst but won’t stipulate their rating. If a swiss balls anti-burst rating is to 100kg then this ball will not suit some people and will be unsafe to use additional weight on. As the DuraBall Pro is rated to 500kg there is a huge safety margin so you can feel confident in the ball’s integrity.
There is no doubt that a swiss ball is a great tool for training (read Benefits of Swiss Ball Training), so before you go out and buy one ask yourself this - is saving a few dollars really worth it, when your health and safety is at risk?
