This research was co-funded by the Erasmus + Sport Programme of the European Union within the project FitBack No. 613010-EPP-1-2019-1-SI-SPO-SCP and the Slovenian Research Agency within the Research programme Bio-psycho-social context of kinesiology No. P5-0142. Background FitBack is an international network established to support the creation of physical fitness monitoring and surveillance systems for children and adolescents across Europe. Aims As a part of the greater scope of the FitBack European project, the FitBack web portal was designed and tailored for various target groups, such as teachers, health professionals, policy makers, parents, and youths, with the aim to promote their physical and health literacy. Methods The FitBack web portal is a free and multilingual online resource, and two of its webpages were evaluated: “Make interactive report” was evaluated by 78 secondary school students and 27 physical education teachers, and “10 steps to design a physical fitness monitoring system” by 14 physical activity promotion policy makers. Validated scales and open-ended questions were used to collect both quantitative and qualitative responses. Results ‘Good’-to-‘excellent’ scores emerged for user experience (5.43–6.36 out of 7) and webpage usability (3.70–4.27 out of 5). Qualitative feedback highlighted positive comments and cues on how to improve website features. Conclusions Results indicate that the current FitBack web portal is a clear and user-friendly mobile health tool, which includes relevant information on how to use and implement youth physical fitness monitoring and surveillance systems. 2023-10-26T11:35:17Z 2023-10-26T11:35:17Z 2023-09-08 journal article Carraro, A., Santi, G., Colangelo, A. et al.
