Abstract
In the article we present an overview of contemporary research concerned with aggression in children and youth in the context of sport. Sport represents an important social environment in which aggressive behavior may be either encouraged or regulated.
Especially social and motivational climate, culture and norms of the sport and expectations towards young athletes seem to play a crucial role. Emphasizing the competition, victory at all cost and using aggression as a means of achieving success may support aggressive behavior in and outside the context of sport.
On the other hand, when the norms of the sport stress the importance of self-control and fair play, it may positively regulate the occurrence of aggression in children and youth both in sport and in life.
