“…Walking has consistently been identified as a preferred type of physical activity by older adults [27,28]. Efforts to increase older adults' use of parks may be most effective if focused on promoting walking [29]. Again, while there are likely benefits to engaging in sedentary activity in parks [12], those interested in promoting physical activity may consider finding ways to help adults gradually transition from sedentary activities to moderate activities such as walking while in the park.…”

Demographic Characteristics and Physical Activity Behaviors in Sixteen Michigan Parks

The Building Healthy Communities (BHC) initiative addresses inadequate physical activity in Michigan using a population-based approach to prevent chronic disease. Eighteen local health departments through 2010 received $1,505,179 to plan and implement community-based interventions to increase physical activity among low-income and minority populations. This paper examines park user demographics, compares park user demographics to the demographic characteristics and examines physical activity behaviors of park users in these parks. BHC Park usage was examined from 2008 to 2010 using the System for Observing Play and Recreation in Communities (SOPARC). One sample binomial tests were used to examine if the proportion of male and female park users was different than the proportion of males and females in Michigan and to examine if the proportion of white and other park users was different than the proportion of whites and others in Michigan. A chi-square goodness-of-fit test was used to examine whether the observed proportions for age groups observed using the park differed from the actual proportions for age groups in Michigan. The majority of BHC park users were white. More children were observed than other age groups. Park users were most often observed engaging in walking or vigorous activity rather than sedentary activities. When comparing the proportion of whites (54.7%) and others (42.8%) observed using the parks to the proportion of whites (79%) and others (21%) residing in Michigan, there was a significant difference (P < 0.001) with a greater proportion of whites and smaller proportion of persons of other ethnicities expected to be observed using the parks. This chi square goodness of fit test showed a significant difference in the observed and expected number of persons observed using the trail in each age group (χ(2) = 4,897.707, df = 3, P < 0.001) with a greater number of children (n = 1,939) and teens (n = 1,116) observed than the number of children (n = 828) and teens (n = 305) expected based on 2010 Michigan census data. A greater proportion of non-whites (compared to whites) were observed using the park than would be expected. In Michigan, 60% of blacks, 37% of Hispanics, and 53% of other minority groups do not meet national physical activity recommendations. Perhaps developing additional parks in Michigan can increase physical activity behaviors among minorities.

“…The large multidomain trials [36,37] currently being conducted are a step in the right direction and will provide valuable information, finally tackling the incidence of dementia as the ultimate primary outcome. Until then, it might be beneficial for clinicians to share the optimism of many community members, patients, and their families, as reflected in recent qualitative research with focus groups discussing physical activity [38][39][40] and to carefully encourage a healthy lifestyle as part of successful MCI and AD management.…”

Regular physical activity undoubtedly has many health benefits for all age groups. In the past decade, researchers and clinicians have begun to focus their attention on whether physical activity also can improve health outcomes of older adults who experience mild cognitive impairment (MCI) or dementia. This ongoing question is gaining relevance in light of the aging of the world population and with it the rise of age-related conditions, such as cognitive impairment. Not surprisingly, physical activity is among the potential protective lifestyle factors mentioned when strategies to delay or prevent dementia are discussed. The first large-scale multidomain intervention trials are under way to put this to the test. This review aims to give an overview of recent trials of physical activity in patients with MCI or dementia.

“…With increasing numbers of older adults living well into their nineties, the number of individuals expected to develop mild cognitive impairment Wilcox et al, 2009) along with having cancer will definitely increase (Courneya, 2003). Older cancer survivors may experience the detrimental effects of a cancer diagnosis in addition to age-related chronic diseases and physical limitations.…”

Assessing the Relationship Between Physical Fitness Activities, Cognitive Health, and Quality of Life Among Older Cancer Survivors

Chemotherapy-related cognitive impairment, known as "chemobrain," has been described as a side effect of chemotherapy and is associated with cognitive changes on quality of life especially among older cancer survivors. This longitudinal feasibility study examined the relationship between physical fitness, cognitive health, and quality of life among two groups of older adults: those on chemotherapy, and those who have completed chemotherapy. To assess cognitive health, we used the Montreal Cognitive Assessment and demographic information from the Healthy Brain Questionnaire. For quality of life, we used the McGill Quality of Life assessment. Physical activity was assessed using Metabolic Equivalency Tasks from the Compendium of Physical Activities classification system. t-Tests and regression analyses indicated that at Time 1 those on chemotherapy had lower cognitive health scores than those off chemotherapy. Yet at Time 2, as physical activities increased, cognitive health and quality of life improved for those on chemotherapy. However, those who had completed chemotherapy also benefited from an increase in physical activities over time. The results have implications for health care practitioners in oncology settings to better inform patients of cognitive challenges resulting from chemotherapy and the importance of participation in physical activities. Future research should compare different age groups among a larger sample.
