ABSTRACT
Positive psychology and applied sport and exercise psychology, though different fields by name and trade, are bedfellows who have remained largely strangers to each other until recently. Most of the theories and bedrock assumptions of positive psychology will be of no surprise to sport psychology practitioners because both fields have developed with the charge of facilitating optimal functioning of human beings. In this chapter, I will discuss potential interchanges in theory between the two disciplines and make concrete suggestions for how positive psychology can inform applied sport psychology practice. What I present is not exhaustive, but it reflects my hope that collegial collaboration will produce an interdisciplinary approach and enhance the richness and complexity of both disciplines.
