On the second day of the Championships, for athletes aged between 15 and 17, medals were available in the women's under-46 kilogram, women's under-49kg, men's under-51kg and men's under-55kg categories at the Bill Copeland Sports Centre.

The final of the men's under-51kg category was contested between Ebrahim Safari Soumeeh of Iran and Jun Jang of South Korea.

The contest was very much a tactical bout with little to separate them in the first round, which ended 0-0.

Finally the Iranian landed a punch, taking the lead 1-0 before Jang levelled things up with 20 seconds to go.

Then, in the dying seconds, Jang landed an arcing ax kick to the head that secured a 4-1 win and the gold medal.

The bronzes were shared by Sheng-lun Huang of Chinese Taipei and Sergei Kirsanov of Russia.

Yu-jin Kim then doubled South Korea's gold medal haul as she overcame Chia Yin Sung of Chinese Taipei in the women's under-49kg final.

Following a scoreless opening round, Kim landed a head kick, taking the score to 3-0.

As the final round got underway, Sung started taking risks, moving in on her opponent but once again she could not strike.

In the last 30 seconds, she forced Kim off the mats, scoring a point on penalties before conceding a point of her own to take the score to 4-1.

With just a few seconds remaining, Kim landed another head kick, extending her lead to 7-2 and securing the gold medal.

The bronze medals were won by Gabriela Brishkarova of Slovakia and Daniela Paola Souza of Mexico.

The third and final South Korean gold today arrived in the under-55kg category where Chan-ho Jung defeated Gashim Magomedov of Azerbaijan for gold.

From the start Magomedov danced around the ring but Jung was unaffected and scored first with a head kick to go 3-0 up.

In the last second of the round, the Korean's coach appealed for another head shot but was denied.

In the second period Jung’s speed secured him another three points from a head kick to go 6-0 up.

At the start of the third Jung struck with another hook kick to Magomedov’s jaw, extending his lead to nine points.

Following a final onslaught the fight ended 12-0 to Jung, with Magomedov taking silver in what was by far the most exciting final of the day.

Ali Baseri of Iran and Houssam El Amrani of Morocco claimed the bronzes.

The fourth gold medal today was won by Napaporn Charanawat of Thailand as she defeated Sweden's Rim Bayaa in the final of the women's under-46kg category.

It was the Thai athlete who drew first blood with an ax kick to the head that dropped the Swede to her knees for a 3-0 lead, before Bayaa responded to score a single point of her own.

Following the opening stages of the second period, Charanawat landed another two head kicks to extend her lead to 10-1 before the Swede landed a blow of her own to the head, taking the score to 10-4.

As the bout entered the latter stages, Charanawat finally seemed to be tiring but, with 30 seconds left and the Swede 11-5 down, Bayaa had her work cut out and launched an offensive.

Charanawat fought back, rather than retreating tactically and waiting for the clock to end it.

In the dying seconds, both fighters tumbled to the floor but Charanwat won 11-7, leaving Bayaa with a well deserved silver.

The bronze medals went to Nuray Muratkyzy of Kazakstan and Abishag Semberg of Israel. 

Prior to the semi-finals today, Booyoung Scholarships were awarded to seven nations: Bangladesh, Botswana, Guadeloupe, Mongolia, Nepal, Rwanda and Ukraine.

Each country received $5,000 (£4,000/€4,700) from Booyoung, an official partner of the WTF.
