Background The mechanisms underlying the cardia-protective effects of physical activity in older adults remain poorly understood. We examined the relationship between objectively measured physical activity during free-living and novel cardiac risk markers, including coronary artery calcium (CAC) and pericardial fat (PF). Methods Participants were 446 healthy men and women (mean age=66±6 ...
Introduction Strategies to increase daily physical activity may be viewed as a mean to counteract the high prevalence of falls in elderly subjects, which is an important and increasing single factor associated with disability, injury and death. On the other hand when the elderly have reduced autonomy and consequent need ...
Background Project OPAL (Older People and Active Living) was funded through Phase 1 of the National Prevention Research Initiative. Its primary aim was to describe the physical activity levels and patterns of adults aged 70 and over using accelerometry. Associations with deprivation of area of residence, perceptions of neighbourhood walkability, convenience and ...
Introduction Most accelerometry research is in children and adults. Literature on accelerometry in older adults is limited and many studies rely on validity studies completed on younger adults to determine cutpoints for exercise intensity. The purpose of this study was: to review the literature to identify studies that used ActiGraph ...
Introduction The Incidental and Planned Activity Questionnaire (IPAQ), renamed to be IPEQ, is a self-report short questionnaire that was developed for use in ageing research. The questionnaire asks about an average week frequency and duration (closed categories) of planned exercise, walking for exercise, walking to places and chores inside and ...
The number of days of pedometer or accelerometer data needed to reliably assess physical activity (PA) is important for research that examines the relationship with health. While this important research has been completed in young to middle-aged adults, data is lacking in older adults. Further, data determining the number of ...
Introduction Accelerometer data provide reliable, valid, and stable measures of physical activity, and also allow for the estimation of sedentary time. Furthermore, as data are date and time-stamped, the outcomes of interventions targeting these behaviors can be explored beyond simple average of change. Methods Stand Up For Your Health [1] was ...
Adequate daily physical activity (PA) is important for maintaining functional capacity and independence in older adults. However, most older adults in Canada do not engage in enough PA to sustain fitness and functional independence. Environmental influences, such as warmer daytime temperatures may influence PA participation; however, few studies have examined ...
Introduction Evidences show a positive relationship between regular physical activity and a high physical fitness on reduction of anxiety and depression levels, improving older people’s quality of life. Maintenance of motor skills is critical to the preservation of an independent lifestyle and quality of life in elderly. The aim ...
Background The purpose of this study was to examine the validity of the Physical Activity Scale for the Elderly (PASE) by comparing PASE scores with physical activity assessed by a portable accelerometer. Methods Experimental design: Correlational-mean activity level over a 3-day period was correlated with PASE scores. Setting: Physical activity ...
