User involvement in design processes is crucial to understanding user context and real needs. This topic is especially relevant in the sports industry since most products need to be highly personalized for specific users to allow for an increase in performance and user experience. This literature review seeks to understand better how users are included in the overall process of designing physical devices for the sports industry and the main user-centred approaches applied. A comprehensive search was conducted on Scopus and Web of Science, and 114 publications were identified. These were then subjected to rigorous inclusion and exclusion criteria, and a critical analysis was performed. As a result, ten articles were considered relevant and included in the review. The content of these documents revealed that most processes analyzed include the user at least in one phase of development, usually to aid in defining requirements or to test and validate prototypes. Besides this, it was also concluded that semi-structured interviews and questionnaires are the preferred feedback collection methods. Two of the articles included in the review present a model for sports design that incorporates the users and holds them in a central place for the development process.
