Having earned his country's first men's world taekwondo gold at the 2017 Championships, Khramtsov further adorned his CV by becoming the first Russian to win an Olympic title in the sport.

Khramtsov initially trained in karate but, in 2011 and aged 13, he changed to taekwondo because he wanted to compete at the Olympics.

The transition proved hugely effective. Aged just 17, Khramtsov reached the final of the Moscow Grand Prix in 2015, reaching the men's under-68 kilograms final. He lost that bout with honour, 16-10 to South Korea's Lee Dae-hoon. The Korean had already won two world titles and would add Olympic bronze the following year in Rio.

Khramtsov rounded off his year by winning the Russian Open title, again in Moscow, before earning gold at the European Youth Championships and then at the European Under-21 Championships.

The following year, Khramtsov retained the latter title while winning numerous open crowns.

He was ready to push on. And, in 2017, at the World Championships in Muju, South Korea, he won the men's under-74kg title with a 6-3 victory over Nikita Rafalovich of Uzbekistan.

Khramtsov thus matched the performance of his compatriot Olga Ivanova, who won the women's over-73kg world title in Puebla, Mexico in 2013.

In 2018, Khramtsov was an emphatic winner of the senior European title at the under-80kg weight, earning a 58-16 win in an all-action final in Kazan against the former Briton Aaron Cook, representing Moldova.

He suffered a rare defeat in the Grand Prix Final at Fujairah, however, losing 27-14 in the final to Norway's Richard Andre Ordemann.

In 2019, he lost his world title, beaten in the round of 32 at the Championships in Manchester at an event where gold went to Azerbaijan's Milad Beigi.

Khramtsov finished the year strongly, however, winning the Rome Grand Prix and Grand Prix Final in Moscow, and he reached the final of the Chiba Grand Prix alongside winning the Military World Games title.

He resumed his career early in 2021 by earning the European under-80kg title - ideal preparation for the postponed Tokyo 2020 Olympic Games in the Japanese capital.

Khramtsov, representing the Russian Olympic Committee, won the men's under-80kg gold with a 20-9 victory in the final over Saleh El-Sharabaty of Jordan.

El-Sharabaty had hoped to follow in the footsteps of Ahmad Abughaush, who made history at Rio 2016 when he became the first Jordanian athlete to win Olympic gold in any sport.

But Khramtsov quickly gained a stranglehold on the bout, and while El-Sharabaty managed to get on the board with a punch before pulling off a superb spinning kick to the head to get within one point of his opponent, he never got any closer and Khramtsov forged ahead again.

Aged just 23, the Russian had reached the top of his sport.
