This scoping review was performed on the generic domains required for physical activity assessment, namely: (1) ‘assessment of maximal heart rate’, (2) ‘determination of basal and/or resting heart rate’, and (3) ‘heart rate-derived intensity zones’, for which we finally included a total of 72, 2 and 11 eligible papers, respectively. Gathering recent knowledge, we provide a decision tree and detailed recommendations for the analysis of free-living HR data to derive individual physical activity profiles. Moreover, we also provide examples of HR-metric calculations that help to illustrate data processing and reporting.
