Duyen had a difficult start in the snatch competition, when she lifted 95 kilograms, which wasn't counted due to a technical foul. She successfully lifted the same weight in her second attempt. She raised the weight to 98 kilograms in her third but failed to lift it. She ended the snatch competition in fourth.
In the clean and jerk competition, Duyen lifted 113 kilos the first time round. However, seeing her opponents improve on their results, the 25-year-old had to increase the weight to 119 kilograms in the next two lifts but failed both attempts. Overall, Duyen registered a total 208 kilograms, the lowest result of her five recent tournaments.
Duyen's result is considered disappointing after predictions showed she could score a silver medal. Before heading to Tokyo, Duyen told VnExpress she hadn't fully recovered from a leg injury, which may have added to her Olympic woes.
