A model of knowledge system concerning invalids' sport is created, including general philosophic, general theoretical and social-theoretical cases, its conceptually-informational modeling is realized. Historical analysis of formation and development of Paralympics, Deaflympic Games and Special Olympic Games is realized. Structural and functional peculiarities of invalids' sport component in the system of international Olympic movement are displayed. Chronology and peculiarities of formation of programs are determined, as well as nosologic structure and peculiarities of classification of invalids' games participants.

Sportsmen with abnormalities of locomotor apparatus and vision participate modern Paralympics, sportsmen with hearing disturbance - Deaflympic Games, athletes with abnormal mentality - Special Olympic Games. They engage in competition in various kinds of sports - both in adopted Olympic sports and non-Olympic ones, as well as in specific - nosologically determined - kinds of sports.Analysis of generalized chronology of summer and winter Invalids' Games has shown that modern invalids' games are carried out in order reflecting tendency of managing organizations of invalids' sports to structural and image localization: Summer Paralympics; Summer Deaflympic Games, Winter Special Olympic World Games; Winter Paralympics; Winter Deaflympic Games, Summer Special Olympic World Games.
