Objectives
To investigate the use of accelerometers to monitor change in physical activity in a childhood obesity treatment intervention.
Methods
28 children aged 7–13 taking part in “Families for Health” were asked to wear an accelerometer (Actigraph) for 7-days, and complete an accompanying activity diary, at baseline, 3-months and 9-months. Interviews with 12 ...
Purpose
Three methods for measuring time spent in daily physical activity (PA) were compared during a 21-d period among 83 adults (38 men and 45 women).
Methods
Each day, participants wore a Computer Science and Applications, inc (CSA) monitor and completed a 1-page, 48-item PA log that reflected time spent in household, occupational, ...
Purpose
The purpose of this investigation was 1) to evaluate agreement between dual-mode CSA accelerometer outputs and Yamax pedometer outputs assessed concurrently under free-living conditions; 2) to determine the relationship between pedometer-steps per day and CSA-time spent in inactivity and in light-, moderate-, and vigorous-intensity activities; and 3) to identify a value of ...
Purpose
The purpose of this investigation was to compare the concurrent accuracy of the CSA accelerometer and the Yamax pedometer under two conditions: 1) on a treadmill at five different speeds and 2) riding in a motorized vehicle on paved roads.
Methods
In study 1, motion sensor performance was evaluated against actual steps ...
Introduction
Children are primarily physically active through formal and informal play. Children with autistic spectrum disorders (ASD) have difficulty engaging in these types of activities because they experience communication and behavior limitations inherent to the condition. These social deficits may cause them to be less active than children without ASD, ...
Purpose
The purpose of this study was to establish the accuracy of five published accelerometer regression equations that predict time spent in different intensity classifications during free-living activities.
Methods
Ten participants completed physical tasks in a field setting for a near-continuous 5 - 6 h-period while oxygen uptake and accelerometer data were ...
Purpose
To evaluate the validity of five physical activity monitors available for research: the CSA, the TriTrac-R3D, the RT3, the SenseWear Armband, and the BioTrainer-Pro.
Methods
A total of 10 healthy men and 11 healthy women performed 10 mm of treadmill walking at 54, 80, and 107 m·min-1 and treadmill running at 134, 161, 188, and 214 m·...
Purpose
The primary aim of this study was to test the validity of two accelerometers, CSA/MTI WAM-7164 and Actiwatch, against direct observation of physical activity using the Children’s Physical Activity Form (CPAF).
Methods
CSA/MTI WAM-7164 and Actiwatch accelerometers simultaneously measured activity during structured-play classes in 3- to 4...
Introduction
Exact evaluation of the quantity and intensity of physical activity in daily life is considered very important due to the close relationship between physical activity level, functional decline and sedentary habits. Even moderate-to-vigorous intense physical activity (PA) is beneficial when done regularly for a total of 30 minutes or longer ...
Background
The journey to school is an opportunity for increasing children’s daily physical activity. However, the contribution that active commuting to school makes to overall physical activity is unknown. This study used objective measurement to investigate the physical activity patterns of children by mode of travel To school.
