While masters sport aligns with the holistic concept of active aging, related research has focused predominantly on the physical domain, and less is known about the psychological, cognitive, and social benefits of older adults' participation. This study examined, in combination, the perceived psychological, social, cognitive, and physical benefits of training and competing as a masters athlete, while considering age and gender differences. Forty masters athletes residing in Canada were interviewed (21 men and 19 women; 15 who were 50–64 years and 25 who were 65–79 years), representing 15 different sports. Interviews were coded both deductively and inductively, revealing several subthemes of benefits for the broader perceived psychological, social, cognitive, and physical benefits, with few but notable differences between women and men, and those younger than 65 years and those 65+ years. Our findings provide new insights into the positive experiences of active aging associated with high levels of physical activity among older adults, such as greater self-confidence, especially for women, comradery, and feeling mentally sharper, especially for the older age group.

We aimed to assess work-related factors and their association with long-term care workers' self-efficacy for encouraging and engaging residents in physical activity. Baseline data from a worksite wellness study with 98 workers were used. We used a linear regression model, to assess if job satisfaction, work ability, and social support for staff health behaviors from coworkers and supervisors were associated with staffs' self-efficacy for Function-Focused Care (FFC) and Staffs' Outcome Expectations for FFC. Staffs' social support for healthy behaviors from coworkers was the only factor that was significantly associated with Staffs' Outcome Expectations for FFC and staffs' self-efficacy-FFC, respectively explaining 19% and 14% of the variance. Our findings show that staffs' social support from coworkers is associated with higher self-efficacy for encouraging and engaging residents in physical activity suggests future worksite wellness studies with long-term care workers may wish to consider assessing program impacts on residents' physical activity levels.

We investigated the quadriceps muscle size and quantitative characteristics in older tennis players. Thirty-eight senior tennis players (70.8 ± 5.3 years) and 38 controls (71.6 ± 5.1 years) were included. To measure the muscle size and quality, we measured muscle thickness in the rectus femoris (RF), vastus lateralis, and vastus intermedius, and muscle echo intensity in the RF and vastus lateralis using B-mode transverse ultrasound, respectively. We measured knee extension peak torque for muscle function. Muscle thickness in the RF, vastus lateralis, and vastus intermedius were significantly larger in tennis players than in controls. Tennis players had a lower echo intensity in RF and a higher knee extension peak torque compared to controls. Stepwise multiple linear regression analysis implied that echo intensity and muscle thickness were predictors of knee extension peak torque. Higher muscle quality contributes to a higher knee extension peak torque in tennis players. Playing tennis may prevent age-related muscle atrophy and maintain muscle quality in older individuals.

Although exercise-induced feeling states may play a role in driving future behavior, their role in relation to older adults' participation in physical activity (PA) has seldom been considered. The objectives of this study were to describe changes in older adults' feeling states during exercise, and examine if levels of and changes in feeling states predicted their future participation in PA. Self-reported data on feeling states were collected from 82 older adults immediately before, during, and after a moderate-intensity exercise session, and on participation in PA 1 month later. Data were analyzed using latent growth modeling. Feelings of revitalization, positive engagement, and tranquility decreased during exercise, whereas feelings of physical exhaustion increased. Feelings of revitalization immediately before the exercise session predicted future participation in PA; changes in feeling states did not. This study does not provide empirical evidence that older adults' exercise-induced feeling states predict their future participation in PA. [ABSTRACT FROM AUTHOR]

Physical activity (PA) is believed to preserve cognitive function in older adulthood, though little is known about these relationships within the context of daily life. The present microlongitudinal pilot study explored within- and between-person relationships between daily PA and cognitive function and also examined within-person effect sizes in a sample of community-dwelling older adults. Fifty-one healthy participants (mean age = 70.1 years) wore an accelerometer and completed a cognitive assessment battery for five days. There were no significant associations between cognitive task performance and participants’ daily or average PA over the study period. Effect size estimates indicated that PA explained 0–24% of within-person variability in cognitive function, depending on cognitive task and PA dose. Results indicate that PA may have near-term cognitive effects and should be explored as a possible strategy to enhance older adults’ ability to perform cognitively complex activities within the context of daily living.

The proportion of older people living in our communities is rising and, to live independently, some require assistance from home care services. Physical activity can improve and maintain function, strength, and balance, which are important for those receiving home care. This study reviewed the evidence on physical activity/exercise interventions trialed with older people receiving a home care service. A systematic review of studies published from January 1982 to September 2012, from five databases, was undertaken. Inclusion criteria were: aged 65+ years; community dwelling; no dementia diagnosis; receiving home care services; and a physical activity/exercise program. Eight articles were included and results show there were few consistencies between intervention types, groups, outcome measures, and follow-up. Study quality was mixed. Future studies should include pragmatic randomized controlled trials involving home care practitioners and their clients to gain “real-world” knowledge of what interventions are effective and can be delivered within this setting.

The aim of this study was to provide information about the relationship of bone mineral content (BMC) and density (BMD) with some physical-fitness-related variables in a sample of women with fibromyalgia (FM) and age-matched women without FM. Twenty-eight women clinically diagnosed with FM (age 51.1 ± 8.4 yr, M ± SD) and 22 age-matched controls participated in the study. Whole-body BMC and BMD, lean mass, handgrip strength, quadriceps strength, and cardiovascular fitness were measured in all participants. The association between physical-fitness variables and bone-related variables was tested by linear regression controlling for body weight as a possible confounder. There were no differences in BMC or BMD between groups. Women with FM had lower values of handgrip strength, quadriceps strength, and VO2peak than the control group. Handgrip strength and aerobic capacity were associated with BMC and BMD and quadriceps strength was associated with BMD in women with FM; however, only VO2peak was associated with BMC in the group of women without FM. Bone mass of women with FM may be more susceptible to changes in physical fitness than that of the women without fibromyalgia. [ABSTRACT FROM AUTHOR]

This study evaluates the separate effect and retention of 12-week traditional (TE) and horse (HE) exercise programs on physical function in healthy older participants (61 to 87 years old). Thirty-eight participants were randomly assigned to three groups: TE (n = 17), HE (n = 10), and control group (n = 11). TE and HE underwent a supervised exercise program (3 day/week). Maximal gait speed, muscle strength, and body balance were assessed at weeks 0, 12, and 16. Only TE and HE displayed significant improvements (P < .05) in knee extensor strength, and only HE had faster gait speed. Marginal balance improvements were found only in HE in the medial-lateral direction. However, TE showed larger improvements in handgrip than HE. The largest retention was in knee extensor strength but most of the exercise effects were lost in the follow-up. Besides TE, exercise with a horse may be an alternative option to older adults, provided that they want to interact with the animal. [ABSTRACT FROM AUTHOR]

Background: Previous research has observed a positive correlation between having greenways or trails proximate to homes and the physical activity behaviors among residents. Few studies using a pre-post research design have been conducted, and each has pointed to the need for more rigorous studies which incorporate an appropriate control group. Methods: Residents from households living within 1 mile of a proposed greenway and those from a control neighborhood located between 2 and 3 miles of the proposed greenway were randomly selected to participate in the study. Participants were mailed a survey before the onset of construction and again 1 year after the trail was opened. Outcomes were the number of days during the previous week that respondents reported participating in walking, moderate activity, and vigorous activity. Results: Repeated measures analyses of variance indicated no significant differences between the experimental and control groups in days of walking, moderate activity, or vigorous activity before and after the greenway was constructed. Conclusions: Findings suggest that building a greenway did not affect the physical activity behaviors of proximate residents. Other studies should consider different trail types from a variety of settings to determine whether physical activity behavior changes may be context specific. [ABSTRACT FROM AUTHOR]

Background: Self-efficacy, action control, and social support are considered to influence changes in physical activity levels in older adults. This study examines the relationship among these variables and explores the putative mediating and moderating mechanisms that might account for activity changes. Methods: A longitudinal study with 54 older adults (= 50 years of age) was carried out in Costa Rica. In a moderated mediation analysis, action control was specified as a mediator between self-efficacy and physical activity, whereas social support was specified as a moderator between self-efficacy and action control. Baseline physical activity, age, and sex were specified as covariates. Results: Action control mediated between self-efficacy and physical activity. An interaction between social support and self-efficacy on action control pointed to a synergistic effect at the first stage of the mediating process. Conclusions: The effect of self-efficacy on physical activity was partly explained by action control, providing evidence of action control as a proximal mediator of physical activity. Moreover, the moderator role of social support was confirmed: high social support appeared to compensate for low levels of self-efficacy. [ABSTRACT FROM AUTHOR]

Background: We examined associations of individual, psychosocial and environmental characteristics with 4-year changes in walking among middle-to-older aged adults; few such studies have employed prospective designs. Methods: Walking for transport and walking for recreation were assessed during 2003-2004 (baseline) and 2007-2008 (follow-up) among 445 adults aged 50-65 years residing in Adelaide, Australia. Logistic regression analyses examined predictors of being in the highest quintile of decline in walking (21.4 minutes/day or more reduction in walking for transport; 18.6 minutes/day or more reduction in walking for recreation). Results: Declines in walking for transport were related to higher level of walking at baseline, low perceived benefits of activity, low family social support, a medium level of social interaction, low sense of community, and higher neighborhood walkability. Declines in walking for recreation were related to higher level of walking at baseline, low self-efficacy for activity, low family social support, and a medium level of available walking facilities. Conclusions: Declines in middle-to-older aged adults' walking for transport and walking for recreation have differing personal, psychosocial and built-environment correlates, for which particular preventive strategies may be developed. Targeted campaigns, community-based programs, and environmental and policy initiatives can be informed by these findings. [ABSTRACT FROM AUTHOR]

Background: Self-efficacy has been found to be an important precondition for behavioral change in sedentary people. The current study examined the effectiveness and added value of including a 15-minute selfefficacy coaching at the start of a 12-week lifestyle physical activity (PA) program. Methods: Participants were randomly assigned to a standard-intervention group (without additional self-efficacy coaching, N = 116) or extra-intervention group (with additional self-efficacy coaching, N = 111). Body mass index (BMI), cardiovascular fitness, self-reported PA, and self-efficacy beliefs were assessed at baseline and immediately after the intervention period. Perceived adherence to the PA program was assessed postintervention. Results: At posttest, a significant increase in cardiovascular fitness and decrease in BMI were found in both groups. Significant intervention effects emerged on PA behavior, self-efficacy, and program adherence, in favor of the extra-intervention group. Self-efficacy mediated the intervention effect on program adherence whereas no evidence was found for its role as mediator of PA change. Conclusions: Adding a 15-minute self-efficacy coaching at the start of a lifestyle PA program is a promising strategy to enhance the intervention effects on PA behavior, self-efficacy beliefs, and program adherence. However, the role of self-efficacy as mediator of the intervention effect on in PA was not fully supported. [ABSTRACT FROM AUTHOR]

Background: Neighborhood walkability shows significant positive relationship with residents' walking for transport in cross-sectional studies. We examined prospective relationships of neighborhood walkability with the change in walking behaviors over 4 years among middle-to-older aged adults (50-65 years) residing in Adelaide, Australia. Methods: A baseline survey was conducted during 2003-2004, and a follow-up survey during 2007-2008. Walking for transport and walking for recreation were assessed at both times among 504 adults aged 50-65 years living in objectively determined high- and low-walkable neighborhoods. Multilevel linear regression analyses examined the associations of neighborhood walkability with changes over 4 years in walking for transport and walking for recreation. Results: On average, participants decreased their time spent in walking for transport (-4.1 min/day) and for recreation (-3.7 min/day) between the baseline and 4-year follow-up. However, those living in high-walkable neighborhoods showed significantly smaller reduction (adjusted mean change: -1.1 min/day) in their time spent in walking for transport than did those living in low-walkable neighborhoods (-6.7 min/day). No such statistically-significant differences were found with the changes in walking for recreation. Conclusions: High-walkable neighborhoods may help middle-to-older aged adults to maintain their walking for transport. [ABSTRACT FROM AUTHOR]
