Accelerometer assessment of physical activity in active, healthy older adults.
Despite widespread use of accelerometers to objectively monitor physical activity among adults and youth, little attention has been given to older populations. The purpose of this study was to define an accelerometer-count cut point for a group of older adults and to then assess the group's physical activity for 7 days. Participants (N = 38, age 69.7 +/- 3.5 yr) completed a laboratory-based cal...
متن کاملassessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
Quantitating physical activity in COPD using a triaxial accelerometer.
STUDY OBJECTIVE To determine the reliability, validity, and stability of a triaxial accelerometer for walking and daily activity measurement in a COPD sample. DESIGN Cross-sectional, correlational, descriptive design. SETTING Outpatient pulmonary rehabilitation program in a university-affiliated Veterans Affairs medical center. PARTICIPANTS Forty-seven outpatients (44 men and 3 women) wit...
متن کاملPhysical Activity Recognition in Daily Life using a Triaxial Accelerometer
Activity recognition with a tri-axial accelerometer worn at the waist could provide an objective measure of physical activity. Current methodology usually trains and evaluates the activity recognition algorithms on laboratory collected data with the goal ultimately being to infer these activities under daily life conditions with free-living subjects. This thesis examines the effects of this by ...
متن کاملAssessment of energy expenditure for physical activity using a triaxial accelerometer.
A triaxial accelerometer was used to evaluate the relationship between energy expenditure due to physical activity (EEact) and body acceleration during different types of activity. In a laboratory experiment, 11 male subjects performed sedentary activities and walked on a motor driven treadmill (3-7 km.h-1). EEact was calculated from total energy expenditure (EEtot), as measured by indirect cal...
