Introduction: The body of evidence about the benefits of physical activity (PA) on health is massive. There are several distinct subjective and objective methods to evaluate PA levels, which can be a source of bias in self-reported outcomes. Objective: The purpose of the present essay was to review findings from recent research with particular focus on PA assessment, and point out some issues for future research. Conclusion: The variability among evaluation methods compromises comparability between studies. Special attention should be given to self-report instruments that can lead to some sort of bias. Therefore, it is important for proper theoretical basis with respect to the objectives and types of PA, which should be considered before selecting the instrument to be applied in a given population. Views of several review studies were discussed and recommendations were presented.
