Background: Objective measures of sedentary behavior (SB) have been validated and used in a number of studies. However, these devices are limited in their ability to provide contextual information regarding the nature of SB. The Sedentary Behavior Record (SBR) is an adaptation of the 3-day Physical Activity Record for quantifying ...
Background: A recent technological advancement in accelerometers has enabled the researchers to examine the cadence (i.e., steps/minute) in a free-living environment, which can be used to quantify the intensity of walking activity (i.e., peak cadence). However, little is known about the optimal measurement conditions (i.e., the ...
Background: Measuring and increasing physical activity among commercial truck drivers is a health imperative due to elevated rates of obesity and associated health problems in the population. However, actigraphy measures of physical activity are likely inflated by large truck seat vibrations during driving periods. Purpose: In preliminary studies recordings ...
Background: Currently there are numerous personal activity monitors on the market that track an individual’s daily steps and energy expenditure. These devices, which are affordable and user friendly, can increase physical activity through motivation and personal goal setting. Although these devices have great potential to measure and track daily ...
Background: Cut-points for physical activity intensity are developed from the relationship between oxygen uptake (VO2) and rate of activity counts determined with accelerometry. This practice assumes that the relationship between VO2 and activity-count rate is stable within people, but this has not been directly examined. Purpose: To examine whether the ...
Purpose:: Objectively measured physical inactivity (PI) has been described as predictor of mortality in adults. However, the assessment of physical activity in daily life by activity monitors is not feasible in clinical practice. We aimed to identify physical fitness tests able to predict PI in adults. Methods: : A total of 120 ...
Purpose: The purpose of this study was two-fold; to compare accelerations between dominant and non-dominant wrists during structured activity bouts; and to determine whether there are differences in wrist accelerations (dominant and non-dominant) between age groups during structured activity bouts. Methods: Participants aged 23 to 79 y performed a block of ten ...
Background: Obesity has been a significant public health concern among US adults. Recently, a great attention has been given to the sedentary behavior (SB) in relation to obesity; however, controversial results have been reported due to the use of less accurate measures of SB and obesity in adults. Purpose: ...
Background: Physical activity (PA) is an important healthy lifestyle behavior that is usually lower among women, and body fat a fitness component usually higher among women compared with men. It is expected that people with higher level of movement skills will engage in more daily physical activities. The association between ...
Purpose: Most of the evidence in physical activity (PA) and sedentary behaviour (SB) has been obtained from developed countries; however in order to promote and improve global and local interventions, evidence from developing countries is needed. The purpose of this study was to describe the PA levels and SB in ...
