Jacinto made his official debut for the 2000 Summer Olympics in Sydney, where he competed in the men"s 60 kg class. He lost the first preliminary match to Algeria"s Omar Rebahi, who successfully scored a single yuko within the five-minute period. At the 2004 Summer Olympics in Athens, Jacinto switched to a heavier class by competing in the men"s half-heavyweight division, despite that he weighed 68 kilograms.
He lost again in his first preliminary match to Kazakhstan"s Muratbek Kipshakbayev this time, by a waza-ari (half-point) and a sukui nage (double leg takedown).
At the 2008 Summer Olympics in Beijing, Jacinto competed for the second time in the men"s 66 kg class. Unlike his two previous Olympic games, Jacinto offered another shot for the bronze medal by entering the repechage rounds.
Unfortunately, he was defeated in his first match by Iran"s Arash Miresmaeili, who successfully scored a yuko and a koka, before the five-minute period had ended.
