Assessing physical performance and physical activity in large population-based aging studies: home-based assessments or visits to the research center?
Published 2 February 2020 The current study aims to compare correlations between a range of measures of physical performance and physical activity assessing the same underlying construct in different settings, that is, in a home versus a highly standardized setting of the research center or accelerometer recording. We also evaluated the selective attrition of participants related to these differen
