Einleitung

We meet the underages crime rate and other social-pathological phenomena more or less in every society. On the basis of a long-term observation on a world-wide scale by some specialists we can claim that the children and juvenile social-pathological phenomena react sensitively to social changes. That has been proved in our country as well. As a result of changed social conditions after 1989 a dramatic increase of various social-pathological phenomena of underages was recorded, above all prostitution, thefts, burglaries, gambling, drug consumption and demonstrations of racism. From 1990 to 1995 the number of criminal acts registered by the police radically increased. In 1994 the necessity to solve this situation brought the government of the Czech Republic to approval of "The programme of social and crime rate prevention". According to the government these problems should be solved by means of such preventive measures that would lead to positive changes in juvenile value orientation, sticking to the behaviour rules and norms, tension relief and direction of aggression. At looking for the educational innovations, an aimed and qualified use of P.E. means is being offered. We did research on possibilities of application of yoga and relaxation techniques in the youth resocialization process in ethopedical institutions. We aimed at the compilation and verification of an special programme, above all for psychical tension relief, aggression reduction and positive changes in self-conception. Researches verify the psychosomatic and psycho-social effects of yoga (Dostalek 1996, Nespor 1994). This means that changes on a physical level can bring about changes in psyche or in interpersonal relations - e.g. the relief of unnecessary physical tension causes relaxation on a psychical level, which manifests itself positively in interpersonal relations and social adaptation.
