Un ruolo importante è rivestito dalle proprietà meccanicheDei materiali di cui è costituita la pista/pedana.
I materiali più utilizzati sono lo Sportflex Super X (Mondo Rubber)
E il Rekortan M99 (APT).

La risposta elastica e quindi la trasmissione delle forze
è quindi determinata da tre componenti:
• Atleta
• Scarpe
• Materiali della pista
