This study is a follow-up study of Reynes and Lorant's studies assessing the effect of one year of judo and karate training on aggressiveness scores among young boys. The data reported here were obtained after a second year of practice, 14 judoka, 9 karateka, and 20 control participants who filled out the Buss-Perry Aggression Questionnaire three times, 1 year apart. At the first assessment, all participants, born the same year, were 8 yr. old and at the third they were 10 yr. old. Analysis indicated that after two years of practice, karate training seemed to have neither positive nor negative effects on aggressiveness scores, while judo training seemed to have a negative effect on anger scores. However, the results suggested the importance of kata or meditation in training sessions on self-control acquisition for such young boys.

The purpose of the present study was to ascertain whether children beginning martial arts training were more aggressive than their peers. 150 8-yr.-old children were administered the Buss-Perry Aggression Questionnaire. Analysis showed that children beginning martial arts training did not score more aggressive than their peers but scored higher on the Anger scale. This difference, however, appeared only in children practicing judo.

Revue canadienne des sciences du comportement, 2004, 36:1, 30-35 Résumé L'objectif de cette étude est de valider une version française du Movement Imagery Questionnaire (Hall & Pongrac, 1983). Les analyses portent sur une population de 127 hommes et 68 femmes. Les résultats montrent une validité de construit (avec la totalité de la population) et une fiabilité test-retest (avec 26 participants) comparables à celles de la version anglaise. Les résultats suggèrent qu'un certain nombre de facteurs tels que le niveau de pratique, le temps de pratique, le sexe et le type de pratique devront être pris en compte dans des études futures pour affiner les réponses relatives à sa validité prédictive.

This study assessed the effect of one year of traditional judo training on aggressiveness among young boys. 27 primary school pupils and 28 judo students were asked to complete the Buss-Perry Aggression Questionnaire at two times 1 year apart. Analysis showed that judoka were more aggressive (had higher scores on Total Aggression, Verbal Aggression, and Anger) than the control group after one year of training, even if variations in aggressiveness were not significant. So, results do not support the view that judo training leads to less aggressiveness in a sample of children this young.
