    The authors of the editorial „Physical activity self-reports: past or future?” take a well thought through approach to this important area. We agree that “self-reports will continue to fill important roles now and in the future”, 1(Pg.1) that a combination of PA assessment methodologies is the most informative approach, and that there is no one-size-fits-all approach to PA self-report. We wish to go a step further and not only argue that self-report very much is part of the PA measurement future but to improve the field of PA-self-report.

    The trend towards a more thorough confinement of PA behavior became obvious in the recently published WHO guidelines,2 which are no longer based only self-reported, but also from device-based measures of PA. The new guidelines now require new approaches to determine guideline adherence (i.e. the guidelines changed from 60 minutes of moderate-to vigorous (MV)PA every day to an average of 60 minutes of MVPA per day in children and adolescents) as well as updating survey questions and sampling methods for future monitoring.2 However, changing the question wording is unlikely to address the need for PA monitoring among children who, especially at young ages, are unable to answer a potentially complex question about average behavior over the past few days, weeks, or months. The alternative of asking daily PA for an entire week may be more accurate but increases survey response frequency and time. Assessing adherence to the new WHO guid...
