Table 2 Main categories of the focus-group discussion on content and methods of physical activity promotion

(1) Explicit concept-based approaches in exercise therapy are comprised of:

 - volitional support (high concept-base) vs. movement experience (low concept-base); and

 - institution-specific adaptations.

(2) The action pattern of ‘Fun and joy in exercise and physical activity’ includes:

 - a diverse spectrum of exercise interventions;

 - (the rediscovery of) individually tailored and enjoyable activity;

 - the promotion of group experiences and activities;

 - reflections on exercise experiences; and

 - an effort to make rehabilitants more receptive to positive and joyful exercise experiences.

(3) Knowledge transfer to the rehabilitants as a theory–practice combination involves:

 - a central principle of reflection in the pairing of knowledge and exercise experience; and

 - the demonstration of knowledge through proximity to everyday life and pictorial language.

(4) Use of material and media for independent training and practice involves:

 - the common but mostly ineffective use of materials in paper form; however,

 - the search continues for modern forms of media use.

(5) Strategies to promote personal responsibility include:

 - the independent use of therapy-free time fostered by different elements;

 - a reduction in consuming attitudes of rehabilitants; and

 - preparation and strategies for concrete continuation at the place of residence of the rehabilitants.
