法國哲學家梅露龐蒂指稱，人以身體為基點，向世界開放，不斷與他人、別物、環境進行全面性實存意義的交流，是在一種開放的、動態的、共存的、循環的、以及不斷探問的辯證關係中進行的。本文依循梅露龐蒂的辯證觀點，進一步為人與世界之間的辯證交流，提出一個具體的「實存溝通」圖像說明，並據此進行網球經驗世界的現象學描繪，確認「實存溝通」恰可成為運動身體經驗反思的基點。

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.
