Notes: Grey shading highlights phenotype models that have already been used in the literature. This refers to the specific combination of an assessment method (eg questionnaire) and a cut-point. aCut-point models: A: Fried’s values, B: specific values of the respective study/questionnaire, C: MVPA recommendations.
