The effects of a walking intervention on depressive feelings and social adaptation in healthy workers.

The effects of walking on mental health problems among healthy Japanese workers are not fully understood. In the present study, we investigated the effects of a four-week walking program on the psychological functioning of a nonclinical sample of healthy workers in Japan.A total of 606 healthy subjects were enrolled in the study and were evaluated by the Zung Self-rating Depression Scale (SDS) and the Social Adaptation Self-evaluation Scale (SASS) both before and after the walking program.
