Rizki Juniansyah broke all three73kg junior world records ©Indonesia Weightlifting Federation

The 17-year-old Indonesian Rizki Juniansyah put in a sensational performance to claim all three junior world records held by the American CJ Cummings at the International Weightlifting Federation (IWF) Junior World Championships in Tashkent, Uzbekistan.

Juniansyah, who already held two world records at youth level, beat his previous best competition total by 42 kilograms and looked as though he could barely believe it as he sank to his knees after his sixth successful lift.

His final clean and jerk of 194kg, which seemed less troublesome than his previous lift 5kg lower, gave him final figures of 155-194-349.

To put that in context it is 6kg more than Cummings made in winning the Pan American senior title last month and 8kg more than the 341kg made by the European champion Daniyar Ismayilov, of Turkey.

Only Shi Zhiyong of China has made a bigger total during qualifying for the delayed Tokyo 2020 Olympic Games.

And yet Juniansyah, from Banten, has never even competed in a senior event.

His only two competitions before today were the 2019 Asian Youth Championships, where he was second at 67kg, and the 2020 Asian Juniors, in which he was fourth behind his team mate Erwin Abdullah.

In an interview after he won an online competition last November, Juniansyah said his best efforts in training were 149-185, so this was a remarkable performance by an athlete who will not be 18 until next month.

Erwin was 18kg behind Juniansyah this time, as was Maksad Meredev of Turkmenistan, but they could not claim medals as they were competing as over-age "extras" in Tashkent, in search of Olympic qualifying points that were denied them when last year’s IWF Junior World Championships were lost to the coronavirus pandemic.

The silver went to Achinta Sheuli of India, and the bronze to Russia’s Gevorg Serobian, on 313kg and 308kg respectively.

It was a second gold of the week for Indonesia after Windy Aisah’s victory in the women’s 49kg.

Three Indonesians hold youth world records - Muhammad Faathir, who had six no-lifts in the men’s 61kg in Tashkent, Juniansyah and Aisah.

Their strong team of young lifters look likely to be a force over the coming years, and Muhamad Yassin, chairman of the Banten provincial weightlifting federation that nurtured Juniansyah, said he was an exceptionally dedicated trainer.

"Rizki is not even 18 years old yet - he will be a mainstay athlete for Indonesia in the future," he told local media.

"He has made Banten and Indonesia proud."

Tunisia and Romania won gold in women’s events.

The 2018 Youth Olympic Games champion Ghofrane Belkhir had a sweep of the medals in the 59kg with 91-120-211, a career best.

She was 17kg clear of Turkey’s Cansel Ozkan, and 19kg ahead of bronze medallist Chiara Piccinno of Italy.

Another Italian, Giulia Miserendino, was on the podium at 64kg, finishing second to the Romanian winner Raluca-Andreea Olaru, who made 98-119-214.

Gulnur Ybray of Kazakhstan was third.

The extra lifter Nuray Levent of Turkey missed her last two attempts but made 101-115-216, which will do no harm to her chances of making it to Tokyo.
