Objective To examine the joint associations of daily time spent in different intensities of
physical activity, sedentary behaviour and sleep with all-cause mortality. Methods Federated …

This study aimed to compare estimations of sedentary time (SED) and time spent in physical
activity (PA) intensities in children with overweight/obesity across different age‐appropriate …

The dynamic work environments of tactical athletes are difficult to replicate in a laboratory.
Accelerometers and inertial measurement units provide a way to characterize movement in …

Background Low levels of physical activity (PA) and high sedentary time (ST) are common in
older adults and lack of PA is a risk factor for cardiovascular disease (CVD). Knowledge …

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 …

Morning, day, or evening chronotypes differ by the circadian timing of alertness and the
preferred timing of sleep. It has been suggested that evening chronotype is associated with …

Background Accurate quantification of daily steps in a cardiovascular patient population is of
high importance for primary and secondary prevention. While sensor derived step counts …

Introduction Wrist-mounted motion sensors can quantify the volume and intensity of physical
activities, but little is known about their long-term validity. Our aim was to validate a wrist …

Background Personality reflects relatively stable and pervasive tendencies in feeling,
thinking and behaving. While previous studies have found higher extraversion and lower …

Background Physical activity is crucial to maintain older adults' health and functioning, but
the health benefits of particular activity intensities remain unclear. The aim of this cross …
