Research indicates that high levels of sedentary behavior (sitting or lying with low energy
expenditure) are adversely associated with health. A key factor in improving our …

Epidemiological studies have associated the negative effects of sedentary time and
sedentary patterns on health indices. However, these studies have used methodologies that …

Background Posture has been recently integrated into activity guidelines, advising people to
limit their sedentary time and break up sedentary postures with standing/stepping as much …

The activPAL™(AP) monitor is well established for distinguishing sitting, standing and

Background Accumulating step counts and engaging in moderate-to-vigorous intensity
physical activity is positively associated with numerous health benefits. The activPAL is a …

Background Recent evidence suggests that physical activity (PA) and sedentary behavior
(SB) exert independent effects on health. Therefore, measurement methods that can …

Background Pooling data from thigh-worn accelerometers across multiple studies has great
potential to advance evidence on the health benefits of physical activity. This requires …
