Based on the work of Martindale et al. (2005) and Henriksen et al. (2010a), researchers have increasingly focused on environmental features influencing talent development in sport from an integrated, holistic perspective. These contributions led to a quickly evolving body of literature and a proliferation of findings related to facilitative and debilitative environmental features. With a timely appraisal of this work warranted, this review aims to coalesce salient results from talent development environment research. For this purpose, a holistic perspective is employed on (a) the environmental level, by considering the sport and non-sport domain and by identifying functional and dysfunctional features, as well as on (b) the outcome level, by considering wellbeing and personal development, alongside athletic development, as important athlete-related outcomes. Following a systematic search, 44 articles were identified and findings summarised by conducting a directed content analysis (Hsieh & Shannon, 2005). Several functional and dysfunctional features were derived from the literature and grouped into the following main categories within a preliminary conceptual framework:
