Motivation is one of the most studied elements in sport psychology due to its great potential to explain the attitude towards sport practice. Therefore, the present systematic review aims to analyse the effects of sport-oriented motivation on physical activity, anxiety and self-concept. The Web of Science and SCOPUS databases were used to select articles published between 2012 and 2022. The criteria established by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement were followed for the elaboration of the systematic review, with the final analysis sample comprising a total of 19 articles. Finally, the analysis of the data reveals that developing sport motivation from extrinsic or intrinsic values can help to decrease or increase anxiety levels. In addition, intrinsic motivation is beneficial for channelling disruptive states, while extrinsic motivation helps to increase anxiety levels when the proposed objectives are not achieved.
