Background: Physical function is an important factor for health and well-being of older adults. Performance-based measures of physical function have been related to an elevated risk of frailty, disability, and mortality. Poor sleep quality has been associated with reduced physical function in older adults. However, little is known about the ...
Background: Sleep and physical activity are both important for executive function; however, few cognitive function studies include comprehensive measurement of both of these behaviors. Understanding how physical activity impacts the associations between sleep and executive function in older women is especially pertinent given the high prevalence of sleep disturbances and ...
Background: More than 650,000 total knee arthroplasties are performed annually to alleviate pain and disability associated with osteoarthritis; a chronic, degenerative condition that compromises the quality of life of 37% of adults over age 60. Despite the decrease in knee pain commonly associated with total knee arthroplasty, little is known about subsequent alterations ...
Background: Aging is associated with detrimental changes in physical function (PF), leading to frailty and disability. Physical activity (PA) has been deemed a best buy for public health. Currently there is limited data on the relationships between PA assessed with body worn sensors and various objective measures of PF. Purpose: ...
Background: Physical activity and fitness are essential to improve or maintain health particularly among elders, but rarely evaluated in community-based programs. Purpose: We tested the following hypotheses: 1) steps/day and time engaged in moderate to vigorous physical activity (MVPA) will be below recommended levels, and 2) steps/day and MVPA will ...
Background: Comparison between self-reported and objective assessment of physical activity (PA) and sedentary time among Hispanic elders in Puerto Rico has not been evaluated. Purpose: We tested the following hypotheses: 1) moderate to vigorous PA (MVPA) behavior will be higher and sedentary time lower with self-report compared with objective assessment, 2) sedentary ...
Purpose/Objectives & Rationale: To compare step count accuracy of ActiGraph GT3X+ monitors (hip and ankle placement) with the StepWatch 3 in geriatric in-patients. Relevance: The StepWatch 3 activity monitor is the gold standard for detecting steps in individuals who walk very slowly. However, because the ActiGraph GT3X+ monitor is ...
Background: The steep decline in physical activity (PA) among the oldest old is not well understood; there is little information about the patterns of change in PA and sedentary behaviour (SB) in older people. Longitudinal data on objectively measured PA data can give insights about how PA and sedentary behaviour (...
Abstract: To explore whether nitrogen retention can differ on an isonitrogenous diet by changing when protein is consumed, we performed a short-term study in older individuals (64.5 ± 2.0 years) performing daily exercise while in energy balance. Participants consumed an isonitrogenous–isocaloric diet with the timing of a protein or carbohydrate beverage after ...
Background: The steep decline in physical activity (PA) among the oldest old is not well understood. Longitudinal objective PA data can give insights about how amount and bouts of PA and sedentary behaviour (SB) change with age. Methods: Men aged 70-90 years, from a UK population-based cohort wore GT3x ...
