The World Para Taekwondo rankings have been updated before the World Championships, which take place in London on Thursday (October 19).

Last month's Pan American Open in Costa Rica was the last chance for taekwondo players to earn ranking points before the event in Britain's capital.

Like other regional championships, the Pan American Open was a G4/G2 event, meaning that fighters from South, Central and North America were able to earn double ranking points.

In the men's under-61 kilograms K44 division, Argentina's Facundo Andres Novik moved up six ranking positions to third in the world, after winning gold. 

Other notable moves were Costa Rica's Edwin Pizarro, gaining 12 positions to move to number 11, and Yandry Larrando Dreke who became Cuba's first ranked player at 24. 

All will be chasing Mongolia's number one, Bolor-Erdene Ganbat, in London.

The men's under-75kg division also saw a lot of movement, with Russia's Vladimir Feofanov moving up six positions to fifth place, after winning Pan American gold. 

Costa Rica's Andres Molina jumped seven spots to number seven, with bronze on home soil, while Felix Sabates of the United States jumped three positions to world number two.

Iran's Mahdi Pourrahnamaahmad will be the one to beat in London, with nearly 110 points separating him from Sabates on top of the pile.

After capturing the US Open and Oceania Open titles already this season, Evan Medell of the US added the Pan American crown to take over the world's top ranking in the men's over-75kg K44 division. 

Compatriot Johnny Birch jumped 20 positions to number 10 after claiming silver, while Mexico's Francisco Pedroza moved up seven spots to number seven.

Para-taekwondo's most competitive division sees both the US number two, Corbin Stacey, and Iran's Ashgar Aziziaghdam, within 2.66 points of Medell.

In the men's under-61kg K43 division, Guatamala's Gersson Mejia moved up two positions to third place, after triumphing in Costa Rica. 

France's Bopha Kong enters London as number one in the division.

In the men's under-75kg K42 group, Daniel Espinosa of the US moves up three spots to number four with his Pan American title. 

Azerbaijan's Nijat Muslumov remains the man to beat in the division.

On the women's side, Peru's Leonor Espinoza Carranza enters the rankings at number eight in the under-49kg division after claiming her first title in Costa Rica. 

However, she will have to defeat Turkey's world number one, Busra Gor, if she hopes to win again in London.

Mexico's Jessica Garcia Quijano also won her inaugural title in Costa Rica and enters the rankings at six.

Russia's Ayshat Ramazanova remains first in the division, while Denmark's three-time world champion Lisa Gjessing is second.

Alyssa Fencil of the US moved up eight positions to fifth in the women's over-58kg K44 division after claiming the Pan American title.

She will have to defeat world number one and hometown favourite Amy Truesdale to repeat the feat in London.
