A handbook for improving the prevention and combating of violence in sports outlines the rules of operation of sports organizations. The document was prepared under the “Fair Game” project and is the first of its kind for Bulgaria. The handbook is intended for coaches and managers of professional and amateur sports clubs who want to improve their management policies and practices. It is practically-oriented and includes a questionnaire for self-assessment of the degree of implementation of the proposed policies and practices. The organizations that participated in its development – the “Bokaya” association and the “Bilitis” Foundation, believe that this Handbook will contribute to improving the self-regulation of sports organizations in the field of preventing discrimination and hate speech based on gender stereotypes, as well as increasing the intolerance of athletes, professional athletes and other stakeholders towards gender-based violence in sports. The manual is implemented as part of the “Fair Game” project, which is implemented with the financial support of Iceland, Liechtenstein and Norway under the EEA Financial Mechanism. The main goal of the project is to improve gender equality and help fight gender-based violence in sports. Serving as basis for the development of the Handbook on combating gender-based violence in sport, a study was carried out within the framework of the project “Fair Play” to assess the situation regarding this issue, within the framework of 205 responses to an online survey aimed at both professional athletes, as well as regular sports enthusiasts. The questions in the survey aimed to identify the most frequent manifestations of gender-based violence in Bulgarian sports, the frequency of these manifestations, the most common victims and perpetrators, as well as the opinion of the respondents regarding the role of coaches and sports club management in prevention and adequately addressing the issue. The data shows a wide spread of sexist language in sports circles in our country, as well as not only verbal, but also physical harassment.
