National physical training policy has been growing to expand people`s participation into Sports For All. As of December 2003, participants of Sports For All is about 39.8%. However, once 5 days working system take effect, it will be expected to increase with demand of adventure sports, outside activities and sports watching due to raise health interest. Since sports activity is more active, there is a safety accident increased. Currently, it shows 127% of safety accident for Sports for All. This percentage is said that about 27,600 number of people who might have this kinds of accident among total 2,100,000 members of the National Council of Sport for All. Therefore, we need to have a strategy as like below. First of all, we need to consolidate of safety device strongly. So, it won`t allow to participate any sports competition if person who doesn`t take out an insurance policy from the National Council of Sport for All. Secondly, it has to set up and develop of the public insurance type instead of having demage responsible insurance policy by sponsor. Then, it might have better compensation for safety accident which it occur from sports competition or any other programs. Finally, for the percentage of safety accident, Korea`s number is higher than Japan`s as like 127% to 0.94%. It also need to release the safety book classified by event, so it will be spread and educate people for every competition and operation of sports program, etc.
