The purposes of this paper were to recognize Mrs. Shriver’s dedication to the development of Special Olympics and introduce the specific competition rules in Special Olympics Games. In June 1962, Eunice Kennedy Shriver started a day camp for children and adults with intellectual disabilities (ID) at her hometown in Maryland. Using the summer camp as an example, Mrs. Shriver identified that individuals with ID were far more capable in sports and physical activities than previously thought. In July 1968 Eunice Kennedy Shriver organized the First International Special Olympics Games at Soldier Field in Chicago, with approximately 1,000 athletes representing 26 states and Canada. In 1977 the First International Winter Games were held in Steamboat Springs, CO. The popularity and reputation of the movement continued growing significantly. In 2007, over 7,000 athletes with ID from 164 countries participated in the 12th Summer Games in Shanghai China and 80,000 spectators observed the opening ceremony. Today, Special Olympics has become the largest sports training and competition program in the world for athletes with ID. The Goal of Special Olympics is to provide opportunities for people with ID to experience the excitement and joy of participation in sports and to enhance physical and social skills, as well as overall health.
