Book excerpt: There appears to be a gap in the literature when it comes to examining the role that grief and loss might play while athletes undergo the reconstruction of their identity post-sport. Navigating Athletic Identity, Retirement Transitions, and Self-Discovery: Exiting the Arena investigates the long and often studied concept of identity in athletes from the perspective of transitioning identity as a potential form of loss. Ultimately, we posit that identity transition should also be understood as a form of identity loss, and research conceptualizing the grieving process that athletes experience in that transition should be studied more deeply.
