A period of exercise program as an intervention program was run for2 months, every week, 3 sessions (45 minutes) per week on the experimental group.After intervention program, aggression scale was run again. The data wereanalyzed by covariance using spss software. The results showed that a significantdifference between control and experimental groups' performance (P<0.001) inaggression which showed that a period of exercise program reduced theaggression and its subscales in the experimental group.
