Walking is a central form of physical activity among older adults that is associated with the physical environment at various scales. This mixed-methods study employs a concurrent nested design to explore objective and perceived environmental characteristics of older adults' local walking routes. This was achieved by integrating quantitative Geographic Information System (GIS) data with qualitative data obtained using the Stanford Discovery Tool (DT). Fifty-nine community-dwelling middle-aged and older adults (14 men and 45 women aged 50+) were recruited in a snowball approach through community centers in the city of Haifa (Israel)...

The present study was designed to compare the effectiveness of exercise programs, exercise with Pilates and Latin dance, on older adults' static and dynamic balance. Thirty two older adults were divided into three groups, Pilates group, Dance group, and a Control group. Static and dynamic balance was assessed with following tasks: a) Tandem stance, b) one leg stance and c) periodic sway with and without metronome guidance. Analysis revealed a significant, reduction of the trunk sway amplitude during the Tandem stance with eyes closed, reduction in the Center of Pressure displacement during one-leg stance, increase in the amplitude of trunk oscillation during the sway task, for both intervention's groups and reduction in the standard deviation of the CoP displacement during the MP task only for the dance group...

The predictive value of the Theory of Planned Behavior (TPB) on intention and physical activity (PA) over time was examined. Data from the Aging Well and Healthily intervention program (targeting perceived behavioral control and attitude, not subjective norm) were analyzed, including pretest (T0), posttest (T1, except subjective norm) and 4-6 months follow-up (T2, PA outcomes only) (N = 387, M age 72 yrs). Structural equation modelling was used to test a TPB model. PA was measured subjectively using the Voorrips sports subscale (T0 and T2), items measuring perceived increase in PA (T1), and adherence to exercises (T1 and T2)...

Rural-residing older adults (OA) are not meeting physical activity (PA) recommendations, such that identifying methods of increasing PA among OA remains an ongoing challenge. This study evaluated the effect of a community-based exergaming program on PA readiness-to-change and self-efficacy among rural-residing OA (n=265). There was a significant (p=.008) increase in readiness-to-change classification from PRE to POST. Significant increases in self-efficacy, or confidence in their ability to be physically active for a prescribed period of time, were detected for 35 (p=...

This study evaluated the feasibility and efficacy of the Aging(Plus) intervention program. Aging(Plus) is an 8-week multi-component motivational program which promotes increased physical activity by targeting adults' negative views on aging (NVOA) and perceptions of control, two known psychological barriers to physical exercise. 62 adults, ages 50-82 years, participated in this feasibility study. We assessed NVOA, perceptions of control, and physical activity level at baseline (Week 0), immediate posttest (Week 4), and delayed posttest (Week 12)...

Culturally appropriate, innovative strategies to increase physical activity (PA) in women of color are needed. This study examined whether participation in SALSA, an 8-week randomized, crossover pilot study to promote PA, led to improved psychosocial outcomes and whether these changes were associated with changes in PA over time. Women of color (N=50) completed internet-based questionnaires on PA, exercise self-efficacy, motivational readiness, stress and social support at three time points. Women reported high socioeconomic status and decreases in exercise self-efficacy and increases in motivational readiness for exercise and number of stressful events (p<...

Global population aging has raised academic interest in successful aging to a public policy priority. Currently there is no consensus regarding the definition of successful aging. However, a synthesis of research shows successful aging can be defined as a late-life process of change characterized by high physical, psychological, cognitive, and social functioning. Masters athletes systematically train for, and compete in, organized forms of team and individual sport specifically designed for older adults. Masters athletes are often proposed as exemplars of successful aging...

Despite the exercise benefits, disparities among diverse older adults continue to exist where African American women have the lowest percentage of any population group in meeting national recommended activity guidelines. Drawing on the philosophical tradition of phronesis (practical reasoning) introduced by Aristotle, we studied perceptions of the exercise value among 14 older African American women. Three themes included: 1) exercise goals (e.g., effort exerted), 2) exercise reasons (e.g., health benefits, enjoyment and convenience, and activity recommendation), and 3) inactivity reasons (e...

This study aimed to examine whether muscle force and tendon stiffness in a muscle -tendon complex alter synchronously following 8-week whole-body vibration (WBV) training in older people. Forty older women aged 65 years and older, were randomly assigned into Control (CON, n=15) and WBV training groups (Exposure Time (ET, n=13) and Vibration Intensity (VI, n=12)). For the training groups, 4-week detraining period was subjected following the training period. Throughout the training/detraining period, force of the medial gastrocnemius (MG) muscle and stiffness of the Achilles tendon were assessed 4 times (0, 4, 8, and 12-week) using a combined system of dynamometer and ultrasonography...

The aim of this study was to compare postural sway during a series of static balancing tasks and during five chair rises between healthy young (mean (SEM) age 26(1) yrs), healthy old (age 67(1) yrs) and master athlete runners (age 67(1) yrs; competing and training for the previous 51(5) yrs) using the Microsoft Kinect One. The healthy old had more sway than young in all balance tasks. The master athletes had similar sway to young during two-leg balancing and one leg standing with eyes open. When balancing on one-leg with eyes closed, both the healthy old and the master athletes had around 17-fold more sway than young...

This study aimed to obtain qualitative information about physical activity (PA), sedentary behaviors (SB) and their determinants and about recently retired adults' needs regarding PA interventions. Four focus group interviews were organized. The most commonly reported PA types were walking, cycling, swimming and fitness. The most commonly reported SB were reading, TV viewing, and computer use. Car use was limited. Most adults agreed their habits had changed during retirement. The most striking PA determinant was the feeling of being a 'forgotten group', having too few tailored PA initiatives available...

This study examined the contributions of individual muscles to changes in energetic cost of transport (COT) over seven walking speeds, and compared results between healthy young and elderly subjects. Twenty six participants (13 young aged 18-30; 13 old aged 70-80) were recruited. COT (O2/kg body mass/km) was calculated by standardizing the mean oxygen consumption recorded during steady state walking. Electromyography signals from 10 leg muscles were used to calculate the cumulative activity required to traverse a unit of distance (CMAPD) for each muscle at each speed...
