Relationships Between Chosen Motor Abilities and Aggression of Boys

The research relates to relationships between motor abilities and aggression. The study was conducted on a representative sample of 517 boys aged 11, 13, 15 and 17. The presented data is part of a more extensive study by Strel et al. (1996). The level of motor abilities was evaluated by 26 tests while aggression was assessed by the Buss-Durkee’s questionnaire. The relationships between motor abilities and aggression were evaluated by means of canonical correlation analysis. Significant relationships between motor abilities and aggression were present only in thirteen year old boys. The common dimension is marked by the subcortical system for regulation of inhibition and excitation of nerve impulses that form the changes in the level of activation and by cortical control. It can be inferred that the first mechanism has the potential for the performance of the action in both sub-spaces, but due to the performance of a complicated motor task (motor space) or the social acceptability of the response to frustration (space of aggression) this mechanism is influenced by particular cortex centers.
