X-Fittt is a combined lifestyle programme in which multiple lifestyle behaviours, physical activity and nutrition are addressed. In the first 12 weeks, participants are guided to live healthily by group sports sessions twice a week and an individual sports session once a week, dietary advice by a dietician and consultation by a physiotherapist. After the first 12 weeks, participants are encouraged to remain physically active. Lifestyle coaching is provided in case needed. X-Fittt is provided by several fitness clubs in the Netherlands.
The aim of this mixed-methods research project is to evaluate 1) the impact of X-Fittt in terms of health, quality of life, and participation on both the short- and long-term and, 2) to unravel the effective elements contributing to the (expected) outcomes of X-Fittt. Research methods include body measurements, questionnaires, focus groups, in-depth interviews and, cost-benefit analysis. The project started in September 2018 and is conducted in close collaboration with Formupgrade (Fitness Club in Arnhem) and Hogeschool Arnhem-Nijmegen (HAN).
