Leslie Ata was 28 years old at the time, and had previously represented Solomon Islands at the 1984 Summer Olympics. He competed in the men's under 75 kilograms event on 30 July. In Olympic weightlifting, each competitor is given three attempts at each discipline, the highest successfully lifted weight counts as the athlete's mark for that portion of the competition. In the snatch Ata missed his first and second lifts on 105 kilograms, before successfully lifting the same weight on his third and final attempt. In his three attempts at the clean and jerk, he first failed to lift 130 kilograms, before successfully lifting that weight on his second try. On his third attempt, he failed to lift 135 kilograms. Ata's total score for the event was 235 kilograms, good for 29th place out of 31 classified finishers. The gold medal was won by Tudor Casapu of the Unified Team with a mark of 357.5 kilograms; silver was won by Pablo Lara of Cuba, and bronze was taken by Kim Myong-nam of North Korea.
