The story behind this ball
A ball designed to last, perfectly suited to young footballers!
Since it's essential to have the right size ball, our teams designed the Training Ball Resist in size 5 for players aged 12 and up.
And to ensure optimal durability, this ball has been subjected to numerous tests in the lab and on the pitch to ensure durability at all costs!
Too light? Too heavy? The weight is standardised!
Between 410 and 450g (Size 5)
How big is it? What's the circumference?
Between 68 and 70 cm (size 5).
Optimal sphericity for a precise bounce!
We analyse the ball's sphericity at 4500 different points and then measure any discrepancies. The average variation must be no more than 1.8% (in accordance with FIFA BASIC rules).
If the ball goes beyond this threshold, our engineers intervene to optimise its shape and guarantee an even, precise bounce with every kick!
Great pressure retention for a great game!
We inflate the ball to the recommended pressure of 0.8 bar. After 72 hours, its pressure must have decreased by no more than 15% (around 0.1 bar), ensuring that the remaining pressure is around 0.7 bar.
This means that it's perfectly normal for the ball to lose a little pressure over a few days. Pump it back up regularly to keep it in good condition.
We've also tested how much water the ball absorbs
We simulate rainy playing conditions in a lab by leaving the ball to sit in 2 cm of water on a rotating base whilst subjecting it to 250 compressions. At the end of the test, the ball must have absorbed no more than 15% of its initial weight.
The perfect bounce for the perfect performance!
Each ball is dropped onto a steel plate 10 times from 2 metres in height. The bounce should be between 125 and 155 cm, with a maximum variation of 10 cm between the highest and lowest bounce, ensuring an even, reliable trajectory.
The ultimate resistance test: the machine shot test
The most demanding test that this ball is subjected to is the machine shot test.
It must withstand 2,500 shots against a concrete slope at 50 km/h at a distance of 2.5 m.
At the end of the test, we rigorously check:
- the ball's general condition: the seams must remain intact.
- the circumference: must not have increased by more than 1.5 cm.
- the sphericity: the variation must not exceed 1.8%
- the pressure: losses must not exceed 12.5%
