Objectives To determine whether quantifying both the absolute and relative intensity of accelerometer-assessed physical activity (PA) can inform PA interventions. We hypothesised that individuals ...

Many photosynthetic microorganisms are able to detect light and move towards optimal intensities. This ability, known as phototaxis, plays a major role in ecology by affecting natural phytoplankton ...

Objectives To describe age-related differences in the absolute and relative intensity of physical activity (PA) and associations with mortality. Methods UK Biobank participants with ...
