The purpose of this study was to examine the enactment and changing process of National Sports Promotion Act by analyzing the situation of politics, economics, society, and culture. Through this study, the following conclusion were drawn; First, in 1962 the National Sports Promotion Act was made to imitate Japan s Sports Promotion Law enacted in 1961. In Korea, the main reason of its enactment was strong political intention. That is, Park, Jung-hee s military government wished the political problem occurred by him settled down soon by attracting the people s attention to the sport. He intented to gain more medals in Tokyo Olympic of 1964 throughout supporting elite sports. Although no medal was gained in the olympic games, its enactment became decisive chance to strongly support and activate sport. Since then, the Act has been located as a sport related fundamental law. Second, National Sports Promotion Act has been changed 24 times since it was enacted. Whenever political regime has been changed, it has been also reformed. In the military political power era, it was activated due to their powerful elite sport policy. However, it has been weakened since Kim, Young-sam took power. The reasons can be concluded as two things; the liquidation of previous military government, and restriction of sport organization for IMF era. Moreover, in 1999 this law was totally changed and lost its identity because of its amendment for 2002 FIFA Korea and Japan World Cup. Finally, we need the enactment of a new sport fundamental law, because current National Sports Promotion Act is almost losing its identity. In the near future, it is necessarily needed for the sport fundamental law to be legislated in order for the unification of sport related laws and systematic development of sport in Korea.
