Abstract: | The application of theories to understand concepts and issues in sport and physical education is viewed as a useful research strategy. Two theories addressing subjective phenomena relevant to sport experiences are presented. Concepts proposed in Martin Buber's I-Thou philosophy of relationship and Mihaly Csikszentmihalyi's flow model exploring the psychology of enjoyment are delineated and compared. Sportrelated research using these constructs is then presented. It is concluded that careful application of theories is a viable and valuable approach for studying complex, elusive phenomena in sport. Further, knowledge derived from such research facilitates understanding and awareness of subjective meaning in sport, and therefore opens individuals to the potential of relationship and flow. |
