With the increasing worldwide population, an ongoing escalation in mild cognitive impairment and dementia is predicted. Motor reserve – the cumulative physical activity experience gained throughout  life, as well as cognitive reserve – the brain’s ability to overcome a pathology, such as neurodegenerative disorders, - has been identified as protective factors in cognitive decline. Thus, this study aimed to investigate the relationship between cognitive reserve, motor reserve, and brain volumetry in older adults. 44 older adults (M = 70, SD = 5.18, 77.3% female) with no self-reported significant neurological, ongoing oncological etc. disorders that might limit their participation in the study were involved in the study. All participants underwent a thorough life-style and psychological assessment, as well as structural brain MRI analysis. Overall, our study indicated the significance of a combination of lifestyle factors in predicting thalamic volume. The results of this study indicate that life-long participation in physical, intellectual, and social activities could be beneficial for preserving the volume of thalamus, which is among the first to decline due to aging.

Understanding periods of the year associated with higher risk for falling and less physical activity may guide fall prevention and activity promotion for older adults. We examined the relationship between weather and seasons on falls and physical activity in a three-year cohort of older adults with glaucoma. Participants recorded falls information via monthly calendars and participated in four one-week accelerometer trials (baseline and per study year). Across 240 participants, there were 406 falls recorded over 7569 person-months, of which 163 were injurious (40%). In separate multivariable regression models incorporating generalized estimating equations, temperature, precipitation, and seasons were not significantly associated with the odds of falling, average daily steps, or average daily active minutes. However, every 10 °C increase in average daily temperature was associated with 24% higher odds of a fall being injurious, as opposed to non-injurious (p = 0.04). The odds of an injurious fall occurring outdoors, as opposed to indoors, were greater with higher average temperatures (OR per 10 °C = 1.46, p = 0.03) and with the summer season (OR = 2.69 vs. winter, p = 0.03). Falls and physical activity should be understood as year-round issues for older adults, although the likelihood of injury and the location of fall-related injuries may change with warmer season and temperatures.

The aim of this study was to longitudinally investigate the association between resilience and mental health in older adults and to determine the influence of physical activity on this relationship. A total of 291 older adults were included in a 2-year follow-up study. Adjusted linear regression models evaluated the association between resilience at baseline and mental health after 2 years in sufficiently and insufficiently physically active older adults. A negative correlation was found between resilience at baseline and depression, anxiety, and stress after 2 years for the overall sample. This association changed after stratifying the group. Sufficiently physically active individuals made greater use of the resilience components “Self-Sufficiency” and “Perseverance,” whereas insufficiently physically active individuals made greater use of “Meaning of Life” and “Existential Singularity.” Physical activity can influence the relationship between resilience and mental health. These results can help guide the devising of more effective interventions for this age group.

Our study examined the association between chronotype, daily physical activity, and the estimated risk of dementia in 170 community-dwelling older adults. Chronotype was assessed with the Horne–Östberg Morningness–Eveningness Questionnaire (MEQ). Daily physical activity (of over 3 METs) was measured with a tri-axial accelerometer. The Korean version of the Mini-Mental State Examination (K-MMSE) was used to measure the estimated risk of dementia. The evening chronotype, low daily physical activity, and dementia were positively associated with each other. The participants with low physical activity alongside evening preference had 3.05 to 3.67 times higher estimated risk of developing dementia, and participants with low physical activity and morning preference had 1.95 to 2.26 times higher estimated risk than those with high physical activity and morning preference. Our study design does not infer causation. Nevertheless, our findings suggest that chronotype and daily physical activity are predictors of the risk of having dementia in older adults aged 70 years and above.

Purpose Urban green space (UGS) shows to be a sustainable resource stimulating physical activity, health and quality of life in the general population. With regard to an aging European population, the purpose of this paper is to investigate the relationship between UGS, physical activity and health-related quality of life (HRQoL) in community-dwelling older adults. Design/methodology/approach Cross-sectional survey data were provided by a sample from Hamburg (Germany), consisting of 272 adults aged⩾65 years. Respondents answered questions regarding HRQoL (Short Form 12), physical activity (German-PAQ-50+) and exposure to UGS. The authors applied a linear regression to analyse the relationship between weekly duration of exposure to UGS and physical activity. While controlling for confounding factors, the authors used a multivariate linear regression model to detect effects on HRQoL. Findings A significant effect (adjusted R2: 4.3 per cent; p-value⩽0.001) was found for weekly duration of exposure to UGS and weekly physical activity. Multiple linear regression showed significant positive effects of weekly duration of exposure to UGS (p=0.010) and weekly time of physical activity (p=0.017) on HRQoL. Age, sex and feeling of satisfaction were identified as relevant confounding factors. Research limitations/implications Future research should continue to explore the indicators that mediate an increase of physical activity and HRQoL in the heterogeneous age band of older adults. Practical implications Findings suggest that community-dwelling older adults are likely to benefit from higher amounts of time in UGS since it is positively associated with both physical activity and HRQoL. Therefore, urban planners should explicitly consider the demands of community-dwelling older adults towards UGS. Originality/value This study is one of the first to examine the relationship between UGS, physical activity and HRQoL in older adults.

This article examines the relationship between daily physical activity and everyday memory using an 8-day diary design with young, middle-aged, and older adults. Contrary to expectations, age differences were not reported in the frequency of memory failures and daily physical activity at the between-person level. Multilevel modeling, however, indicated that on days when adults engaged in leisure exercise (physical activity performed during leisure or free time), they reported fewer memory failures, and this was most apparent for older adults. Lagged analyses indicated that when leisure activity was reported on one day, fewer memory failures were reported the next day, and this was especially true for older adults. Thus, findings demonstrate that the benefits of physical activity for memory in later life are observable on a short-term daily basis.
