He competed in the decathlon and heptathlon for the team Dukla Prague.

This record was broken by Dvořák's compatriot Roman Šebrle in 2001.

Dvořák is the only athlete to score over 8,900 points three times.

Dvořák announced his retirement in July 2008, after he failed to qualify for the Beijing Olympics.
