Meaning of 'structured to suction and rebound'

[All Potted Out]

"The track material is structured to suction and rebound at the same time."

What does it mean by "structured to suction and rebound"?

[Mister Micawber]

.
I think:

The material is designed with the ability to absorb impact and then resume its form.

But I may well be wrong. What kind of track are we speaking of?

It's the field track on campus we are talking about...
Does "resume its form" mean that the track would change its form and then change back? (Would tracks change like this? )

[Mister Micawber]

.
Like rubber-- it would be squeezed/pressed down by the weight of running feet, and then resume its shape (rebound) when the weight was removed.

Suction (not a common verb) may well mean that it has an adhering, non-slip property, for good traction.
