Career
Zitnansky has established a Slovak record-breaking throw of 67.20 m in the discus at Nacht van Volharding in Beveren, Belgium. Zitnansky made his official debut at the 1996 Summer Olympics in Atlanta, where he competed as part of the newly-formed Slovak team in the men"s discus throw. He unleashed the discus into the field with a throw of 51.50 m on his third attempt, finishing thirty-eighth overall in the prelims.
Eight years after competing in his last Olympics, Zitnansky qualified for his second Slovak team, as a 33-year-old, in the men"s discus throw at the 2004 Summer Olympics in Athens.
Unlike his previous Olympic feat, Zitnansky steadily recorded a 53.30-metre throw on his opening attempt in the prelims. Followed by a single foul and a throw slightly shorter than his first by 1.43 m on his next two attempts, Zitnansky finished thirty-sixth in the overall standings against a field of thirty-nine athletes, and did not advance further to the final.
