This work consists of a phenomenological study in karate, capoeira and MMA, in which the fight is anchored in the philosophical perspective of M. Merleau-Ponty. In the field of psychology, one historically perceives a privilege to the mental processes, putting the discussions on the body in a secondary place. More specifically, in sports psychology, the most traditional writings and practices are based in an objective and technicalistic look at the body. In this sense, phenomenology is considered as a strong ally for a perspective that emphasizes the body as the main topic of the combative processes. It is proposed here the analysis of three distinct fights -karate, capoeira and MMA. These ones were chosen as an attempt to consider subjectively and culturally distinct understandings of a fight, as identified in the literature. In this sense, this study aims to understand the body to body process in combat, from the experience of karate, capoeira and MMA practitioners, paying attention to the psychological and cultural processes concerning the lived constitution in the practice of each of these modalities. Semi-structured interviews were conducted with karate, capoeira and MMA practitioners, with at least 5 years of practice and who had already taught or competed in the modality. These data were analyzed from a phenomenological perspective, searching for a structure for the fight in each of these modalities. Karate fight was unfolded in an attentive wait of the best way to strike the other with a decisive hit; as well as in the notion of distance, which is fundamental since its origins. In the case of capoeira, its strong relation with the music and with the Afro-Brazilian culture and history is emphasized, in which the fight appears through movements that resemble a dance. In the case of MMA, the combat brings strong individualistic appeal, seeming to correspond to Western and contemporary ideals, as each athlete makes his/her own game, the way he/she feels more at ease and in accordance with what is required to win each opponent. These results highlight distinctions in the three modalities in question, but also point to similarities, indicating a structure which can be understood as the body to body in combat. We consider its fundamental aspects, mainly through the lens of Merleau-Pontyan phenomenology, if we turn to the notions of body, movement, perception, action and habit. As a dialogue with sports psychology, gender issues are discussed in the field of martial arts & combat sports, as well as the processes of prohibition and sportization concerning karate, capoeira and MMA. It concludes with the proposition of an attentive regard to the body and its movements, through a look and listening which not ends in theoretical assumptions and interpretative frameworks. This is fundamentally about the insistence on a process of constant elucidation, especially in relation to the body to body in combat.
