North Korean pocket rocket Om Yun Chol broke his own weightlifting world record at the Asian Games on Saturday, while host South Korea matched powerhouse China's gold medal haul with five on the first day of competition.

Less than 24 hours after a vibrant opening ceremony marked the launch of the 17th Asiad, Om hoisted more than three times his own bodyweight with a superhuman lift of 170kg in the clean and jerk.

Standing just 152 cm and weighing 56 kg, Om's mighty lift came near the end of a day in which 18 gold medals were split between eight countries.
