The objective of this paper is to analyze the of flow concept and its epistemolog- ical evolution within sport research. The analysis highlights that the investigation about flow changed its's initial interest in describing these experiences to privilege its’ measuring and control, aiming to predict and to facilitate sport performance. Nevertheless, this evolution has been materialized with no satisfactory definition or delimitation of this concept. This arti- cle suggests to retake the care with the linguistic nature of flow and to deepen, this way, the meaning of these experiences to those who live them.
