The purpose of this study was to analyze scientific production on the topic of sport coaches in Spain, using doctoral theses included in the Spanish Ordered Theses TESEO database. Productivity was analyzed based on 17 variables grouped into contextual information, object of study, classification criteria, research design and research procedure. Sixty indexed theses were studied from the time period of 1996 to 2017, showing a progressive growth of scientific production in theses during this time. The role of women in the direction and writing of theses still represents a minority. The majority of theses are classified in the scientific disciplines of Sport Pedagogy and Exercise Psychology. The results show that quantitative methodological approaches predominate with descriptive research on populations using surveys or systematic observation. The most commonly used type of sampling was intentional with a questionnaire to collect data. The results show the profile of this research topic, the methodological approach, and the research tendencies as well as underlining the basic lines for development.
