Purpose Accurate measurement of physical activity in children is a challenge. Combining physiological (e.g., heart rate (HR)) and body movement registration (e.g., accelerometry) may overcome limitations with either method used alone. This study aimed to compare the estimated physical activity energy expenditure (PAEE) from hip- and ankle-mounted MTI ...
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 ...
There is growing recognition of the role of the environment in influencing health and health behaviours, and an environment that encourages excess energy intake and reduced energy expenditure is widely considered to be a driving force behind population-wide weight gain. Expert bodies have highlighted the importance of environmental factors on ...
Background This study evaluated the utility of several lower cost physical activity (PA) assessment instruments for detecting PA volume (steps) and intensity (time in MVPA or activity time) using convergent methods of assessment. Methods Participants included 26 adults (9 male) age 27.3 ± 7.1 years with a BMI of 23.8 ± 2.8 kg/m2. Instruments evaluated included the ...
This paper describes the application of best practice recommendations for using accelerometers in a physical activity (PA) intervention trial, and the concordance of different methods for measuring PA. A subsample (n=63; 26%) of the 239 healthy, sedentary adults participating in a PA trial (mean age=47.5; 82% women) wore the ActiGraph monitor at all 3 ...
Introduction The aim of this study was to evaluate the agreement between the ActiGraph accelerometer and the Bouchard diary to estimate energy expenditure (EE) in a Spanish adolescent population. Methods Sixty-one Spanish adolescents, aged 12-16 years, were recruited for this study. The Bouchard diary and the ActiGraph were administered for 3 ...
Objective To measure the levels and patterns of physical activity, using accelerometers, of 11-year-old children participating in the Avon Longitudinal Study of Parents and Children (ALSPAC). Design Cross-sectional analysis. Setting ALSPAC is a birth cohort study located in the former county of Avon, in the southwest of England. This study ...
Background Healthy lifestyles may help to delay arterial aging. The purpose of this study is to analyze the relationship of physical activity and dietary pattern to the circadian pattern of blood pressure, central and peripheral blood pressure, pulse wave velocity, carotid intima-media thickness and biological markers of endothelial dysfunction in ...
Objective Juvenile primary fibromyalgia syndrome (JPFS) is a chronic pain condition associated with significant impairment in physical functioning, but no studies have used newer technologies such as actigraphy to document objective physical activity levels in JPFS. Methods This is the first study to objectively describe physical activity in JPFS patients ...
Background Nowadays, decreased physical activity is considered to be a contributor to increase the prevalence of many diseases such as obesity, coronary heart disease and so on. Many researches demonstrated that regular physical activity reduce all cause mortality. To increase the physical activities of the population, accurate estimation of the ...
