Career
Vivenes represented Venezuela at the 2008 Summer Olympics in Beijing, where he competed as a lone male wrestler in the men"s 96 kg class. He received a bye for the second preliminary round, before losing out to Kazakhstan"s Taimuraz Tigiyev, who was able to score nine points in two straight periods, leaving Vivenes without a single point. Because his opponent advanced further into the final match, Vivenes offered another shot for the bronze medal by entering the repechage bouts.
Unfortunately, he was defeated by Cuba"s Michel Batista in the first round, with a technical score of 1–3.
