Table 2 Modified Principles of the Community-Based Participatory Research following Israel et al. [9]

(1) The network sees itself as a unit.

(2) The network builds on existing strengths and resources.

(3) The network works transparently and in partnership.

(4) The network promotes joint development, empowerment, and capacity building.

(5) The network creates a balance between knowledge generation and interventions for the mutual benefit of all partners.

(6) The network focuses on specific needs in the context of physical activity promotion, taking into account sociodemographic and gender characteristics as well as systematic geographical data.

(7) The development of measures and implementation strategies takes place in a cyclical, iterative, and reflexive process.

(8) All results and developments will be made accessible to all partners; further dissemination and use will also take place in coordination.

(9) The aim is to create the basis for long-term cooperation and the establishment of the topics as a cross-sectional task of all partners involved (health in all policies), with the intention of sustainably promoting the physical activity (and health) and physical literacy of vulnerable groups.
