The first aim of this study was to explore the prevalence of Exercise Dependence (ED) in the Norwegian male population. The second aim was to examine what characterize men with high scores on Exercise Dependence Scale–Revised (EDS-R), when it comes to mode of exercise, exercise frequency, exercise intensity, exercise at a competitive level and hours exercising at the gym. To achieve these aims 5000 questionnaires were sent to randomly selected men between 18 and 65 years in Norway, and 1824 returned completed forms. Cases were excluded when data were missing and the final sample consisted of 1546 men. The questionnaire consisted of the Norwegian translated version of the Exercise Dependence Scale- Revised (EDS-R), demographic items and items that inquired about exercise-related characteristics. Results showed prevalence of exercise dependence in the male Norwegian population of 0.4%, and a higher occurrence of exercise dependence symptoms (21.4%). Higher total EDS-R score were found among these sub-groups of men: men engaging in power and weight class sports, exercising frequently, that often exercise with high intensity, exercising at a competitive level, and exercising more than 5 hours a week at the gym. The results offer insight into ED in the Norwegian male population, but more research is needed to further elucidate the phenomenon.
