The paper discusses Heideggerian understanding of hermeneutics in relation to human being (Dasein), with a brief introduction to the main characteristics of Dasein, showing the place of hermeneutics within Dasein's existence, together with Heidegger's re-interpretation of the hermeneutic circle. This understanding is applied to sport, focusing on the experience of athletes and on the possibilities for interpretations towards authentic existence, including its ethical aspect.
