Anchor: The mid-point of the Rio Summer Olympics has already come and gone. Taekwondo, which will decide whether South Korea earns enough medals for an overall standing of tenth place, will begin on Wednesday. Team Korea says it has finished adapting to new regulations for the sport, which prevented the athletes from performing well four years ago at the London Games.
Our Kim In-kyung has more.
 
Report: The traditional Korean martial art of taekwondo has been a reliable source of medals for South Korea at each Olympics.
 
But South Korea only garnered one gold and one silver in the event at the 2012 London Olympics. It was the worst showing ever for the team as athletes failed to adapt to newly introduced body gear that include electronic sensors.
 
At the Rio Olympics, the sport's governing body has decided to put sensors in head gear as well.
 
Team Korea says it has prepared well for the new regulation and that it won't falter as it did four years ago.
 
Athletes are said to have concentrated on defending themselves against kicks to the head as a successful head kick awards three points. They have also practiced making their kicks as accurate as possible.
 
Park Jong-man, the head coach of the taekwondo national team, says athletes trained to cover themselves against kicks by Europeans, who tend to have longer legs than Koreans.
 
The taekwondo team has finished acclimating to the local atmosphere by training in São Paulo and says it can add to South Korea's medal tally to bring the country's overall count to tenth place at the Rio Olympics.
