Both beat rivals from Uzbekistan in their finals, although the latter nation did pick up three gold medals in La Nucía to finish the Youth World Championships with an event-high five titles.

Nakota defeated Aziza Zokirova on a split decision to win the women's under-70 kilograms title.

"I had three fights at this World Championships with very good rivals, I've never met all of them," Nakota reflected after the decision went to a bout review. 

"It was a great experience. 

"I hope this final fight was spectacular, too. 

"Now I will move to elite boxing and will train hard to achieve my goals in this age group."

Zasenok beat Rakhmatullo Boymatov, also after a bout review was initiated, to win the men's under-80kg crown.

The IBA has controversially suspended the Ukrainian Boxing Federation (UBF), alleging Government interference.

The IBA recognises its own vice-president Volodymyr Prodyvus as the UBF President, but Kyrylo Shevchenko claims instead to be the national body's leader and is listed by Ukraine's Ministry of Justice as someone with the right to execute the UBF's legal acts.

Ukrainians had been told at last month's European Junior Championships that they would have to compete under an IBA flag, but a U-turn ultimately followed and they can box under the Ukraine flag at IBA events once more, including in La Nucía.

IBA President Umar Kremlev is Russian and the organisation is heavily reliant on sponsorship money from Russia's state-owned gas and oil giant Gazprom, so the suspension of the UBF raised eyebrows given the ongoing Russian invasion of Ukraine.

Several National Federations - particularly from the Common Cause Alliance which backed Boris van der Vorst for the IBA Presidency instead of Kremlev - have opposed the suspension of the UBF.

Three men - under-67kg fighter Javokhir Ummataliev, Fazliddin Erkinboev at under-71kg and under-75kg's Turabek Khubibullaev - won Uzbekistan's three gold medals on the final day of the event.

The Cuban delegation also had a strong day, with under-86kg boxer Ronny Álvarez Noa and Ricardo Adrian Fresneda at under-92kg both winning men's gold medals.

Enriko Itauma from England won the men's super-heavyweight crown, stopping Ukrainian Oleksandr Zelenskyi in the final.

England also picked up the women's under-81kg title via Amber Moss-Birch, who beat Uzbekistan's Oltinoy Sotimboeva.

Ireland, Kazakhstan, India and Norway also won gold medals.

Boxers from Russia and Belarus are absent from the Youth World Championships owing to what the IBA called "logistical restraints", despite it now allowing both nations' flags to fly at its tournaments an overturning an athlete ban related to the war in Ukraine.

Spanish authorities reportedly refused to issue Russian and Belarusian boxers with visas.
