The recent thinking on physical inactivity among the young has led to the development of intervention strategies (IS) in schools, families, and communities. These strategies now seem appropriate for giving young people control over physical activity (PA). This narrative study examines IS studies that aim to improve young people’s PA (from age 5 to 17). The review used a variety of databases (i.e., Google Scholar, Eric, Sport Discus, ProQuest) to look at the past 30 years and understand the purpose and impact of IS on the PA of young people. This made it possible to describe contexts in which IS were initiated, classify IS used by researchers, list the major IS research objectives, and identify resulting recommendations for future IS implementation. This work is the first to classify IS information. More specifically, it highlights the great diversity of IS, their implementation contexts, and their relative effectiveness on young people’s PA, especially long term.
