Anger, hostility and aggression reflect the emotional, cognitive and behavioural dimensions of a personality construct often subsumed under the generic term hostility.
Based on personal experience of fitness trainers, Gavin noted that bodybuilders tended to have aggressive personalities, a characteristic that may be further reinforced by the use of steroids.
Bodybuilders were often motivated by the desire to rid themselves of aggressive tendencies.
Observations such as these suggest the value of examining associations between bodybuilding dependence, anger, hostility and aggression. Also, they suggest that constructs such as stress and motives for bodybuilding might contribute to the understanding of dependence.
