Exercise addiction: Links, risks and challenges faced

Abstract

IntroductionExercise addiction is a condition described by a craving for physical training resulting in excessive exercise behaviour and withdrawal symptoms. It has not been accepted as a mental disorder and further research is needed to examine the pathology of the condition.ObjectivesExercise addiction is suggested to have links to other mental disorders and risks in terms of negative consequences such as injuries. Treatment for exercise addiction faces several challenges as the condition is associated with ambivalence, and studies based on controlled interventions are missing.AimsThe aim of this study was to examine and interpret the existing research on links, risks and challenges faced in treatment interventions.MethodsA literature review was conducted in the databases PubMed, PsycINFO and Scopus with the terms: “exercise addiction, excessive exercise” and/or “comorbidity, eating disorder, depression, anxiety, personality, pain, injury, illness, social isolation, stress, intervention, treatment”.ResultsExercise addiction seems to be associated with eating disorder pathology, obsessive-compulsive behaviour and personality traits characterized by perfectionism, narcissism and neuroticism. Overload injuries (e.g. stress fractures) and impaired interpersonal relations are reported. In a treatment context, low compliance is described as a challenge. Thus, motivational interviewing is recommended, and also cognitive behavioural therapy is suggested for treatment. None of these interventions have yet been scientifically evaluated in addicted exercisers.ConclusionThis review concludes that exercise addiction has links to psychopathology and increases the risk of injuries. More research is needed to estimate the level of psychosocial and physiological distress in these athletes. Controlled treatment interventions have to be conducted.Disclosure of interestThe authors have not supplied their declaration of competing interest.
