Abstract
This chapter reviews new quantification possibilities for the assessment of physical activity, a variable intimately related to good health. First, a variety of existing instruments are described with regard to their validity and functionality. Then, their applications are analyzed and categorized into two broad branches: sedentary lifestyle prevention and applications in special population segments. The authors’ intention is to make existing possibilities for assessment of physical activity known to researchers and public health professionals, as it is important for the achievement and promotion of active and healthy lifestyles in the population.
