The aim of this paper is twofold: (1) to integrate several theoretical perspectives into a novel Meta-model of Adaption in Sport (MAS model) and (2) to support the MAS model with a narrative literature review on change-provoking events and related adaptation processes, factors involved, and outcomes. The MAS model is designed to account for two potential tracks of adaptation – fast and prolonged – that are situated along the continuum of adaptation experiences in sport. In each track, sport performers experience various types of sport-related events (i.e., acute events or change events) that are associated with specific sets of demands and perceptions related to self-efficacy beliefs and challenge-threat appraisal. Accordingly, the performer responds to these events by using the mechanisms which determine his/her adaptation process and outcomes. We present a narrative review of the literature related to both adaptation tracks that provide empirical support to the MAS model and conclude by offering reflections on the MAS model and its potential applications in sport psychology research and practice.  © 2023 International Society of Sport Psychology.
