Introduction While many studies report lower daily physical activity (PA) in older compared with young adults, few have focused on how PA patterns may vary over the course of a day. Our working hypothesis is that older adults who report fatigue may adjust their behavior such that they accumulate relatively ...
Purpose The 2010 physical activity (PA) guidelines for older adults in the UK include a target of 150 minutes of moderate or vigorous PA (MVPA)/week and recommend minimizing time spent being sedentary in extended periods. There are few large studies of objectively measured PA in the elderly which can estimate the ...
Introduction Assessing time spent in different activity types may be important for early detection of mobility limitations in older adults. To date, accelerometer-based activity type prediction using machine learning algorithms have not been validated for this segment of the population. Therefore, the aim of this study was to use Random ...
A physically active lifestyle and quality sleep are associated with lower risk for obesity and cardiovascular disease. Cross-sectional studies demonstrate that greater physical activity (PA) is associated with better quality sleep. However, few studies have examined this relationship using objective measures. Additionally, few studies have examined the directionality of the ...
Purpose To examine characteristics of accelerometer-assessed sedentary behavior among older women. Methods An ancillary study to the Women’s Health Study is collecting 7 days of accelerometer-assessed (Actigraph GT3X+) physical activity and sedentary behavior data in ~15,000 women. This analysis includes data from the first 5,032 (mean age, 70.1 yr) women with ≥4 days ...
Clinically assessed gait speed is a valuable test of older adults’ functioning and an important predictor of adverse outcomes including disability, cognitive decline, falls, institutionalization, and mortality. It is logical to pursue correlates of gait speed. Purpose To evaluate the relationship between accelerometer-determined indicators of free-living walking volume (steps/day, ...
Accurately assessing physical activity behavior in children, older adults, and adults with functional limitations is essential to further our understanding of determinants of physical activity behavior in these populations, and to designing, implementing, and evaluating interventions designed to increase physical activity participation. Objective methodologies to assess physical activity behavior, due ...
Background Physical activity is essential for older peoples’ physical and mental health and for maintaining independence. Guidelines recommend at least 150 minutes weekly, of at least moderate intensity physical activity, with activity on most days. Older people’s most common physical activity is walking, light intensity if strolling, moderate if brisker. ...
Introduction Regular physical activity (PA) in older adults is critically important to ensure healthy aging. The link between PA and prevention of disease, maintenance of independence, and improved quality of life is supported by strong evidence. However, there is a lack of data on population levels of PA among older ...
Background Humans have an innate connection and attraction to nature, often referred to as ‘biophilia.’ Exposure to nature has been reported to have a positive impact on health, and several studies have documented that engaging in physical activity outdoors improves mental health and well being. Exact mechanisms remain unknown but ...
