Sport in South Korea
Taekwondo, a popular martial sport is often claimed to have historical origins on the Korean peninsula with origins said to have been traced as far back as the 1st century BCE. However, such historical claims are difficult to empirically verify and separate from the influences of neighboring counties. The sport rose to prominence following the end of Japanese occupation with the end of WWII. Formalized rules were established in 1961 and in 1988 the sport became an Olympic event. The name "Taekwondo" literally means "way of foot and fist", although the modern emphasis lies on the kicks. This may be a way to help legitimize the sport's connection to the traditional practice called Taekkyeon, which originated in Korea during the Goguryeo period in the 4th century. Taekkyeon uses open hands and the feet, where as the use of clenched fists is not permitted. The motions are smoother and more curvilinear than in Taekwondo. Although both disciplines start with the sound "tae" in English, there is no relationship.
