Exercise addiction, although not yet officially recognized, can be defined as the harmful practice of physical exercise, described as a compulsive need, where damage take precedence over the benefits of this practice, with a continuation of this behavior despite the negative consequences. A number of risk factors have been identified, including psychopathological conditions such as eating disorders or other addictions. It is possible to detect this addiction and assess its intensity using multidimensional questionnaires, even the clinical relevance and thresholds of which are still debated. Despite the absence of validated treatments, motivational approaches and cognitive-behavioural therapies can be useful, combined with nutritional management if necessary, as well as management of concomitant disorders.
