There is a need for interventions, and indeed, there are many examples of novel, technology-based physical activity programs delivered within a research setting. However, to date, few attempts have been made to disseminate randomised control trial-tested (RCT) programs to the community at scale. This program of research has been conducted within a larger interdisciplinary research study that brings together health science and marketing principles to promote “Active Team”, an evidence-based physical activity smartphone app, the effectiveness of which has been tested in an RCT. Specifically, this thesis aims to experimentally examine the use of different advertising factors and their relative effectiveness in the wide scale dissemination and uptake of Active Team.enonline social networks;physical activity;social mediaExerciseHealth behavior.Internet advertising.Mobile appsthesis
