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 investigation examined differences in functional sit-to-stand power/velocity between cohorts of adults aged 18-97 years. This study included 264 healthy adults classified into 4 cohorts (18-40, C1; 60-69, C2; 70-79, C2; ≥80, C4). Participants completed the sit-to-stand task 5 times. Power and velocity were measured via the TENDO power analyzer. Absolute average power was maintained from C1-C3, but decreased (p<.01) in C4. Absolute peak power decreased between C1-C2 (p<.01), was similar between C2-C3, and decreased in C4 (p<...

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...

The purpose of this study was to investigate the effects of the addition of a dual task to multicomponent training on cognition of active older adults. Eighty physically active older adults were divided into an intervention group (IG) and a control group (CG). Both groups performed multicomponent training over 12 weeks. The IG simultaneously performed exercises and cognitive tasks. The Mini-Mental State Examination, the Montreal Cognitive Assessment and the Clock Drawing Test were used for cognitive assessments...

Positive physiologic and cognitive responses to aerobic exercise have resulted in a proposed cardiorespiratory (CR) fitness hypothesis in which fitness gains drive changes leading to cognitive benefit. The purpose of this study was to directly assess the CR fitness hypothesis. Using data from an aerobic exercise trial, we examined individuals who completed cardiopulmonary and cognitive testing at baseline and 26 weeks. Change in cognitive test performance was not related to CR fitness change (r(2)=0.06, p=0...

The aim of this study was to identify determinants of walking and whether walking maintained mobility among women as they transition from their mid-70s to their late 80s. We used 12 years of follow-up data (baseline 1999) from the Australian Longitudinal Study on Women's Health (n=10,322). Fifteen determinants of walking were included in the analysis and three indicators of mobility. Longitudinal data analyses techniques were employed. Thirteen of the 15 determinants were significant predictors of walking. Women in their mid-70s who walked up to one hour per week were less likely to experience loss of mobility in very old age, including reduced likelihood of using a mobility aid...

The aim of the present study was explore perceptions of group-based walking and gather suggestions to inform the development of a group-based walking intervention among older adults in retirement villages. Twenty-four physically inactive residents (16 female, 8 male; age range: 69-88) and 4 managers from four retirement villages were interviewed. Inductive thematic analysis revealed 6 broad themes: lack of motivation, values versus constraints, fears and confidence, need for structure, creating a sense of belonging, and the physical environment as a double-edged sword...

Functional fitness (FF) and gait ability in older populations have been associated with increased survival rates, fall prevention and quality of life. One possible intervention for the improvement of FF is well-structured exercise programs. However, there are inconsistent findings regarding the effects of exercise interventions in the maintenance of gait parameters. The aim of this protocol is to develop a community-based exercise intervention targeting an older population. The intervention aim is the improvement of gait parameters and FF...

This study investigated the relationships between muscle echo intensity (EI), physical activity (PA) and functional mobility in 108 Japanese (88-92 years). We measured EI and muscle thickness (MT) at the midpoint of the anterior superior iliac spine and patella using B-mode ultrasound. Light and moderate to vigorous PA (LPA and MVPA) were assessed with a tri-axial accelerometer. Timed up and go (TUG) test was measured for functional mobility. EI, but not MT, was significantly associated with both TUG scores (β=0...

We tested a social cognitive model of physical activity (PA) in the cultural context of the Czech Republic, a post-communist central European country. In total, 546 older Czech adults (mean age=68 years, data collected in 2013) completed a battery of questionnaires assessing indicators of PA and related social cognitive constructs, including self-efficacy, social support, and self-regulation strategies. Subsequently, a structural equation model was used to test the relationship between the social cognitive constructs and PA...

The efficacy of the use of an upper body compression garment (UBCG) as an ergogenic aid to reduce thermoregulatory strain in older adults remains unknown. The aim of this study was to evaluate the effects of UBCG on thermoregulatory, cardiorespiratory and perceptual responses during cycling in a temperate environment (~25ºC, 66% rh) in trained older adults. Twelve cyclists aged 66±2 years performed an intermittent 1-h cycling trial at 50% of the peak power output followed by 10 min of passive recovery. Participants were provided with either commercially available UBCG or control garment in a randomized order...

Participation in surfing has evolved to include all age groups. Therefore, the purpose of this study was to determine whether activity levels and cardiovascular responses to surfing change with age. Surfing time and heart rate (HR) were measured for the total surfing session and within each activity of surfing (paddling, sitting, wave-riding and miscellaneous). Peak oxygen consumption (VO2peak) was also measured during a laboratory-based simulated surfboard paddling on a modified swim bench ergometer. VO2peak decreased with age during simulated paddling (r=-0...

The purpose of study was to demonstrate age-related changes during gait initiation (GI). Therefore, displacement, velocity, total power, mean and median frequency of COP trajectories were measured during phases of GI in anteroposterior (AP) and mediolateral (ML) directions. The older group demonstrated the slower and lesser displacement in comparison to the younger group during anticipatory phase in AP direction and during locomotor phase in AP and ML directions. Also, the median and mean frequency were greater in the older relative to the younger group during anticipatory phase in AP direction, while these were lesser in older than younger group during locomotor phase in AP and ML directions...
