Purpose Our recent study of three accelerometer brands in various ambulatory activities
showed that the mean amplitude deviation (MAD) of the resultant acceleration signal performed …

Objective Accelerometers are increasingly used for objective assessment of physical activity.
However, because of lack of the proprietary analysis algorithms, direct comparisons …

Background We evaluated the association of accelerometer-based sedentary behaviour
and physical activity with the risk of cardiovascular disease. Design The design of this study …

Background The 6‐min walk test (6 MWT ) is cost‐effective and well‐documented field test
for assessing functional exercise capacity and response to medical interventions in diverse …

Background : Studies measuring physical activity (PA) and sedentary behavior on a 24/7
basis are scarce. The present study assessed the feasibility of using an accelerometer at the …

Background Using raw acceleration data to assess the intensity of physical activity enables
direct comparisons between studies using different accelerometer brands. Mean amplitude …

Background Regular physical activity (PA) confers many positive effects on health and well-being.
Sedentary behavior (SB), in turn, is a risk factor for health, regardless of the level of …

Background Longitudinal studies demonstrate an average decline in physical activity (PA)
from adolescence to young adulthood. However, while some subgroups of adolescents …

Motives for physical activity may vary considerably by age, sex, and the level of physical
activity. We aimed to examine motives for physical activity in older men and women with …

We examined the agreement in time spent on different physical activity (PA) levels using (1)
mean amplitude deviation (MAD) of raw acceleration from the hip, (2) wrist-worn Polar Active…
