چکیده مقاله:

The purpose of this study was to examine the effects of sedentary behavior on anxiety and mood symptoms. Using a quasi-experimental design, a volunteer sample of 32 males regularly (300 minutes/week) engaging in physical exercise were compared with 32 sedentary males matched in age. Active and sedentary status was self-reported by the participants. All 64 individuals were initially administered the Overall Anxiety Severity Impairment Scale (OASIS) and the Center for Epidemiological Studies depression Scale (CESD-R) and randomly assigned into a regular exercise intervention group (n=32) or a sedentary behavior intervention group (n=32). Individuals in the regular exercise group were instructed to do 30 minute treadmill walking, and 30 minute stationary bike workout every day for 4 weeks while those in the sedentary group were instructed not to engage in any form of exercise for 4 weeks. Both groups completed the OASIS and the CESD-R at the end of the intervention period. Scores of 4 subgroups of participants differing in terms of pre and interventional exercise-sedentary status were compared. Significant differences in anxiety and depression were observed between the Active-Active and Sedentary-Sedentary sub-groups. A significant group x time interaction effect was observed, with post- hoc contrast tests indicating increased OASIS and CESD-R scores in the Active-Sedentary group and decreased anxiety and depression scores in the Sedentary-Active and Active–Active groups. Intervention group in Visit 2 compared with Visit 1. That is, participants who increased their sedentary behavior after a period of regular exercise reported increased anxiety and negative mood problems. Conversely, those who increased their physical activity after being sedentary, reported decreased feelings of anxiety and negative mood. Significant decreases in negative mood and anxiety were also reported by those who continued with their exercise regime. Findings imply that not only does regular exercise have the impact of reducing negative mood states, but sedentary behavior appears to have the deleterious effect of increasing negative mood states. Physical activity programs can may be recommended to prevent and treat negative emotions such as anxiety and depression.
