The aim of this essay is to present, first, whether Maurice Merleau-Ponty's ”dialectical look” of the lived body and the lived world offers an adequate setting for understanding sport embodiment; second, its implications for a phenomenological description of being-in-the-tennis-world in specific and sport embodiment in general. To do so, we draw on Merleau-Ponty's dialectical account and delineate four guiding clues for understanding the continuous exchange of existential meanings among the lived body, other bodies, the media, the things, the surrounding atmosphere, and the world. We propose this phenomenon as the ”existential dialogue” between the lived body and the lived world. Then a thorough-going phenomenological description of being-in-the-tennis-world discloses an exemplar existential dialogue in sporting experience. We conclude that there is always an overall existential dialogue in progress as one of the fundamental modes of man's sport embodiment.
