Variation in accelerometer counts during rhythmic and non-rhythmic activities
INTRODUCTION: Novel methods to identify physical activity mode and predict energy expenditure from accelerometer data use measures of variability to improve precision. For example, in one approach, the standard... Continue Reading >>>

Time engaged in moderate to vigorous physical activity correlates with number of steps in Hispanics living with HIV
BACKGROUND: The recommendation of at least 150 min/week of moderate to vigorous physical activity (MVPA) in continuous bouts of at least 10 min, and a minimum of 10,000 steps/day... Continue Reading >>>

Intensity of activity in the energy expenditure of older adults
BACKGROUND: Higher levels of physical activity energy expenditure in older adults are associated with lower all-cause mortality as well as higher levels of physical function. The intensity of activity... Continue Reading >>>

An interactive computer program for improving the accuracy of self-reported physical activity intensity
Several expert panels recommend a minimum of 30 minutes of moderate-intensity physical activity (PA) on most days of the week. However, the measurement of PA intensity remains a challenge... Continue Reading >>>
