Most of the research in this field that has been done is on healthy young men, this means that the results from the majority of the studies cannot be applied to women and their bodies, especially in sport, health and exercise. In this study we are investigating the phenome of a woman's menstrual cycle relative to the male coaches knowledge. This study aims to examine male soccer coaches and their knowledge about the menstrual cycle, their relationship with the players and how it affects the conversation climate. To investigate this, semi-structured interviews were conducted with six male soccer coaches who coaches girls in the ages of 11-15. The collected data were analyzed with phenomenology analysis. The result: Male soccer coaches' knowledge about women's menstrual cycle is low and needs to be improved. The results also showed that a relaxed relationship with an open communication enables coaches and players to feel comfortable to talk about external and personal topics. Conclusion: The knowledge of the menstrual cycle needs to improve. Satisfaction of the concept, safety, knowledge, awareness and openness seems to be important to coaches and makes it easier for them to talk about more personal and private topics with the players.
