Research into daily physical activity (PA) patterns of older adults (≥70 years) has primarily relied on self-report. This study used accelerometry, an objective measure of minute-by-minute movement, to assess PA volume and intensity performed by older adults recruited to the Better Ageing project. Results were used to estimate the degree to which current(More)
BACKGROUND There are many health and social benefits of physical activity (PA) for older adults, but little is known about their activity patterns. PURPOSE The purpose of this study was to objectively assess the PA patterns of older adults and the lifestyle and demographic factors associated with PA. METHODS Participants (N = 230, aged 78.1 yr)(More)
Previous studies have reported a decrease in muscle torque per cross-sectional area in old age. This investigation aimed at determining the influence of agonists muscle activation and antagonists co-activation on the specific torque of the plantarflexors (PF) in recreationally active elderly males (EM) and, for comparison, in young men (YM). Twenty-one EM,(More)
BACKGROUND A key public health objective is increasing health-enhancing physical activity (PA) for older adults (OAs). Daily trip frequency is independently associated with objectively assessed PA volumes (OAs). Little is known about correlates and these trips' transport mode, and how these elements relate to PA. PURPOSE to describe the frequency,(More)
Increasing evidence suggests that physical activity can prevent some aspects of mental illness in older people such as depression, dementia and Alzheimer’s disease. Additionally, limited research has shown that engagement in structured exercise can improve aspects of psychological well-being such as mood and self-perceptions in older adults. However, the(More)
OBJECTIVE To examine the associations between sedentary behaviour (SB) measured objectively and by self-report and cardiometabolic risk factors. METHOD Cross-sectional analyses of adults ≥60 years who participated in the 2008 Health Survey for England. Main exposures were self-reported leisure-time SB consisting of TV/DVD viewing, non-TV leisure-time(More)
BACKGROUND AND PURPOSE Patients with suspected stroke first assessed by ambulance paramedics require early recognition to facilitate appropriate triage and early treatment. We determined paramedic's accuracy in detecting acute stroke signs by comparing agreement between neurological signs recorded in the Face Arm Speech Test (FAST), a stroke recognition(More)
This study explored the associations of the volume and intensity of physical activity and the volume of sedentary time with subjective well-being in a diverse group of 228 older adults in the UK (111 female, mean age 78.2 years (SD 5.8)). Physical activity (PA) and sedentary behaviour were assessed by accelerometry deriving mean steps per day, mean(More)
The relationship of objectively measured sedentary time (ST), frequency of breaks in ST, and lower extremity function (LEF) was investigated in a diverse sample aged ≥ 70 years (n = 217). Physical activity (PA) was assessed by accelerometry deriving moderate-vigorous PA (MVPA) minutes per registered hour (MVPA min · hr(-1)), registered ST (ST min · hr(-1)),(More)
OBJECTIVE To investigate the food shopping habits of older adults in the UK and explore their potential associations with selected health-related indicators. DESIGN A cross-sectional study including objectively measured physical activity levels, BMI, physical function and self-reported health status and dietary intake. SETTING Bristol, UK. SUBJECTS A(More)
