Movement, non-movement behaviors and physical performance in older adults: An isotemporal substitution approach

The aims of this study were: (i) to analyse the associations of the time dedicated to movement and non-movement behaviours (i.e., lying down, sitting, standing, and locomotion) with PP (Time up and Go test and the Short Physical Performance Battery); and (ii) to examine how theoretically reallocating time between these behaviours is associated with this outcome.
