Given that most of our sample was expected to be sedentary [7, 15], the remaining participants (i.e. those in quartiles 2, 3, and 4 of light physical activity-to-sedentary time ratio) were classified as high sedentary. MVPA status was classified as ‘physically active’ or ‘physically inactive’ on the basis of whether or not participants met the WHO (World Health Organization) physical activity recommendations for older adults [30]. For this, at least one of these three premises had to be met: accumulate 150 min of moderate physical activity per week over periods of at least 10 min; accumulate 75 min of vigorous physical activity per week over periods of at least 10 min, or accumulate 150 min per week of an equivalent combination of MVPA over periods of at least 10 min.
