Resumo
Considering exercise has positive and negative reinforcing properties, the mood states of sedentary, nonexercise-dependent and exercise-dependent volunteers were compared after maximal exercise testing. Mood status was evaluated by the Beck Depression Inventory, Trait-State Anxiety Inventory, and Profile of Mood States (POMS). No differences were detected before the test or after it, indicating little possibility of positive reinforcement. However, a significant reduction in the POMS Tension-Anxiety scores was observed in both exerciser groups (greater in the exercise-dependent group) but not in the sedentary group. Only in the exercise-dependent group were significant reductions in Anger and Total Mood Disorders scores observed compared with their pre-exercise scores. These data suggest that exercising has stronger negative reinforcement properties for exercise-dependent volunteers and is a factor which could increase the odds of their becoming dependent on exercise.
