Self-reported measures versus objective measures of physical activity and sedentary behaviour : impacts of cardiovascular fitness and physical activity

Physical activity (PA) and sedentary behaviour (SB) can be quantified with both self-report and objective measures, using questionnaires and accelerometers, respectively. There is a paucity of research investigating the possible influence that cardiorespiratory fitness and PA might have on the accuracy of self-reported of PA and SB. This is especially important with the increasing evidence around the risks of SB, independent of PA. The aim of this research study is to describe the difference between self-reported measures of moderate PA, vigorous PA and SB against their objectively measured counterparts. The secondary aim is to identify factors influencing the error in self-report measures; including cardiorespiratory fitness and levels of PA.
