摘要:The relationship between conceptions of masculinity and sport injuries is presented in this paper describing how male gym users, including bodybuilders and fitness practitioners, have shown risk behaviors that are typical of their gender. A qualitative and quantitative study was applied as a part of the methodology at a gym in the city of Hermosillo, Mexico, focusing on injury risks related to masculinity and their prevention. Questionnaire of injuries disposition and in-depth interviews were applied to gym users. Most of the surveyed users showed knowledge of the proper use of gym equipment and stretching and warming techniques as well as the support of the gym instructors. The main cause of injuries is related to behaviors, since they chose not to ask for instructions to show power and strength to others as a result of the male competitive tension that exists among them due to conceptions of masculinity. It is concluded that, in fact, there is a relationship between conceptions of masculinity and sport injuries. Users report the existence of social tension and that for the sole reason of being male they feel the responsibility and obligation of being the best without taking any prevention or safety measure.
