Impact of Physical Activity on the Self-Perceived Quality of Life in Non-Frail Older Adults

Accelerometer-based and self-reported physical activity and sedentary time and their relationships with the P300 in a Go/No-Go task in older adults

Older adults who experience cognitive decline are more likely to have a reduced quality of life. Identifying lifestyle factors that may influence cognitive processing and in turn improve quality of life during older adulthood is an important area of interest. Cognitive function, as measured by the P300 event-related potential (ERP), has been noted to be modified by physical activity; however, no study to date has examined relationships between this neurophysiological measure and physical activity and sedentary time in older adults. Furthermore, there is a gap in understanding as to whether physical activity and sedentary time assessed using self-reported and accelerometer-based methods similarly relate to the P300. This study aimed to assess the P300 during a Go/No-Go task in relation to self-reported and accelerometer-based physical activity and sedentary time in a community sample of 75 older adults. Results indicated that participants engaging in more moderate-to-vigorous physical activity had larger P300 amplitudes across self-reported and accelerometer-based measurements; however, no relationships between sedentary time and P300 amplitude were observed. Notably, accelerometer-based moderate-to-vigorous physical activity explained P300 amplitudes over and above self-reported moderate-to-vigorous physical activity-an effect that remained significant even after accounting for age. Although these results highlight the importance of moderate-to-vigorous physical activity in relation to cognitive function, as measured via the P300 in older adults, a secondary analysis indicated that engaging in lifestyle activity may have similar effects on the P300 as moderate-to-vigorous physical activity. In sum, the present study highlights the role of habitual engagement in physical activity as a possible means for supporting cognitive function during the aging process.

The effect of exercise on resilience, its mediators and moderators, in a general population during the UK COVID-19 pandemic in 2020: a cross-sectional online study

Background

Resilience is central to positive mental health and well-being especially when faced with adverse events. Factors such as exercise, location, sleep, mental health, and personality are moderators and mediators of resilience. However, the impact of these factors on resilience during severe adverse events are unknown. The present study examined how the COVID-19 pandemic affected resilience and its moderators and mediators by investigating whether there was a difference in resilience and quality of life between people with varying levels of exercise, including those who changed their exercise levels pre and during a COVID-19-related lockdown, and whether location affected the relationship between levels of exercise and resilience and quality of life.

Methods

Following ethical approval, a cross-sectional online survey capturing data on self-reported key moderators and mediators of resilience before and during the COVID-19 lockdown imposed on the 23rd March 2020 in the UK was distributed via social media and completed over a three week time period during July 2020 via a self-selecting sample of the general population (N = 85). The key moderators and mediators of resilience the survey assessed were exercise, location, life-orientation, mental health, and sleep quality. All data were self-reported.

Results

Participants’ exercise intensity level increased as resilience increased (F(2,82) = 4.22, p = .003: Wilks’ lambda = .82, partial n² = 0.09). The relationship between exercise, and resilience and quality of life was independent of sleep and mental health status pre-lockdown (p = .013, p = .027 respectively). In the face of the COVID-19 pandemic, this relationship was dependent on mental health but not sleep quality (p = <.001 for resilience p = .010 for quality of life). There were no statistically significant differences between participants living in urban or rural locations.

Conclusion

Exercise is strongly correlated to resilience and during a pandemic such as COVID-19 it becomes a mechanism in which to moderate resilience. The relationship between exercise and resilience is supported by this study. The influence that a pandemic had on mental health is mediated by its effect on quality of life.

COVID-19 lockdowns' effects on the quality of life, perceived health and well-being of healthy elderly individuals: A longitudinal comparison of pre-lockdown and lockdown states of well-being

PURPOSE

. The concept of lockdown in relation to COVID-19 is thought to have an indirect impact on the quality of life and well-being of the elderly due to its consequences on the physical, psychological, and cognitive health of individuals. However, previous published studies on this subject are limited in terms of methodological approach used, including the absence of pre-confinement status and the type of experimental design, which is often cross-sectional. The present study proposes a longitudinal design with pre-confinement measures. It assesses changes in quality of life, perceived health, and well-being by comparing the period before lockdown (T1 = December 2019), three months after the start of the first lockdown (T2 = June 2020), and during the second lockdown (T3 = January 2021) due to COVID-19.

MATERIALS AND METHODS

. This study is conducted with a group of 72 healthy elderly persons. They completed an electronic (online) survey assessing personal factors, activities, and participation as well as responding to the EuroQol-5D and Warwick-Edinburgh Mental Well-being Scale.

RESULTS

. A decrease in quality of life, perceived health and well-being was observed between T1 and T2 and between T1 and T3, but no difference was reported between the two lockdown periods. The variables associated with these changes included energy level, level of happiness, physical activity, change in medical condition, memory difficulties, level of perceived isolation and age.

CONCLUSION

. This study will help to target variables that may have a deleterious effect on older adults for consideration in future confinement settings and for preventive purposes.

Physical Exercise: A Novel Tool to Protect Mitochondrial Health

Mitochondrial dysfunction is a crucial contributor to heart diseases. Alterations in energetic metabolism affect crucial homeostatic processes, such asATP production, the generation of reactive oxygen species, and the release of pro-apoptotic factors, associated with metabolic abnormalities. In response to energetic deficiency, the cardiomyocytes activate the Mitochondrial Quality Control (MQC), a critical process in maintaining mitochondrial health. This process is compromised in cardiovascular diseases depending on the pathology's severity and represents, therefore, a potential therapeutic target. Several potential targeting molecules within this process have been identified in the last years, and therapeutic strategies have been proposed to ameliorate mitochondria monitoring and function. In this context, physical exercise is considered a non-pharmacological strategy to protect mitochondrial health. Physical exercise regulates MQC allowing the repair/elimination of damaged mitochondria and synthesizing new ones, thus recovering the metabolic state. In this review, we will deal with the effect of physical exercise on cardiac mitochondrial function tracing its ability to modulate specific steps in MQC both in physiologic and pathologic conditions.

Tests of muscle function and health related quality of life in healthy older adults in Sweden

BACKGROUND: Life expectancy among older adults has dramatically increased and they are one of the fastest growing populations worldwide. Maintaining quality of life and the ability to live independently are often of greater importance than overall life expectancy. OBJECTIVE: To present reference values for tests of muscle function, and to study the relationship to a commonly used tool of generic health related quality of life (HRQL) in older Swedish adults. METHODS: The study consisted of 192 individuals (105 women) aged between 65 and 80. The tests included hand grip and isometric knee extension strength measurements, the standing heel rise test and a 30 m walking test. Health-related quality of life (HRQOL) was evaluated using the SF-36. RESULTS: Reference values for the measured parameters are presented. There were high correlations (n= 192) between handgrip and leg extension strength (r= 0.72–0.75; p< 0.01). The walking test’s self-selected speed demonstrated the strongest correlation with the physical component summary of the SF-36 (r= 0.57; p< 0.01) and with maximal speed, moderate correlations were demonstrated with muscle strength (r= 0.43–0.56; p< 0.01) and the heel rise test (r= 0.45; p< 0.01). CONCLUSIONS: This study presents reference values for simple tests of muscle function which are relatively easy to perform, used in a Swedish clinical setting performing screening for older adults.

Factors Affecting Quality of Life Among the Elderly in Long-Term Care Hospitals

BACKGROUND

There are challenges in sustaining person-centered care in aged care settings. Key related issues of concern such as quality of life among the older people in long-term care hospitals and interactions with nursing staff have been described previously.

PURPOSE

This study was designed to explore the factors affecting quality of life among older people living in long-term care hospitals in South Korea.

METHODS

Older adult patients (N = 202) in three long-term care hospitals completed measures of cognitive functions, depression, care dependency, and interactions between nurse and patient and a quality-of-life assessment tool. Univariate analyses were used to examine the relationships among these variables, and a multiple linear regression analysis was used to explore the extent to which these variables predicted quality of life in these patients.

RESULTS

The significant factors associated with quality of life were found to be cognitive functions (r = .373, p < .001), care dependency (r = .350, p < .001), and depression (r = -.504, p < .001). The regression model with depression and care dependency as predictor variables accounted for 25.7% of the variance in quality of life.

CONCLUSIONS/IMPLICATIONS FOR PRACTICE

The correlation found in this study between quality of life and depression and care dependency provides additional evidentiary support for developing and applying nursing interventions that reduce depression and care dependency in older adult populations.

Physical Activity Amount and Cognitive Impairment in Korean Elderly Population

The relationship between physical activity amount and cognitive function in elderly Koreans has received little attention. This study therefore aimed to understand the independent and common link between cognitive function and physical activity levels among elderly Korean adults. This study recruited a total of 2746 elderly adults (1348 males and 1398 females). All participants were assessed for cognitive functioning using the Korean Dementia Screening Questionnaire Cognition (KDSQ-C). The computerized Korean version short form of the International Physical Activity Questionnaire (IPAQ) used in this study was entirely based on the long, self-administered, usual week-long IPAQ found in the IPAQ manual of operation. In the unadjusted model, elderly adults who met the recommended level of moderate-to-vigorous physical activity were more likely to have a sufficient level of cognitive function. Hemoglobin, creatinine, cholesterol (TC), triglycerides (TG), LDL-C, and HDL-C differed significantly between groups. A negative correlation was found between KDSQ-C score and the moderate-to-vigorous physical activity (MVPA) amount per week. Physical activity amount is associated with cognition function in Korean elderly adults. Increasing physical activity may improve hemoglobin and creatinine and be involved in improving serum lipid profiles in elderly adults. Thus, physical activity has been suggesting as a useful tool to reduce the risk of cognitive function associated with aging.

Exercise Interventions for Community-Dwelling Older Adults Following an Emergency Department Consultation for a Minor Injury

This study compared effects of exercise-based interventions with usual care on functional decline, physical performance, and health-related quality of life (12-item Short-Form health survey) at 3 and 6 months after minor injuries, in older adults discharged from emergency departments. Participants were randomized either to the intervention or control groups. The interventions consisted of 12-week exercise programs available in their communities. Groups were compared on cumulative incidences of functional decline, physical performances, and 12-item Short-Form health survey scores at all time points. Functional decline incidences were: intervention, 4.8% versus control, 15.4% (p = .11) at 3 months, and 5.3% versus 17.0% (p = .06) at 6 months. While the control group remained stable, the intervention group improved in Five Times Sit-To-Stand Test (3.0 ± 4.5 s, p < .01). The 12-item Short-Form health survey role physical score improvement was twice as high following intervention compared with control. Early exercises improved leg strength and reduced self-perceived limitations following a minor injury.

Dual-tasking in older women: physical activity or else?

The interplay between gender, Physical Activity (PA), and Dual Tasking (DT) in older adults is unclear. This study aimed to address DT based on gender and PA level. One-hundred and twenty older adults (81 women and 39 men) participated. Timed up and go test and spatiotemporal gait measures were collected in single and DT conditions. Participants were grouped according to gender and PA level. Physical activity did not explain gender differences, women were slower and had shorter stride lengths when DT regardless of PA level. Findings indicate the necessity for tailored PA and functional interventions to improve women's performance.

Promotion of Healthy Aging Within a Community Center Through Behavior Change: Health and Fitness Findings From the AgeWell Pilot Randomized Controlled Trial

The purpose of this randomized controlled trial was to determine if behavior change through individual goal setting (GS) could promote healthy aging, including health and fitness benefits in older adults who attended a community "AgeWell" Center for 12 months. Seventy-five older adults were randomly allocated to either a control or a GS group. Health outcomes were measured at baseline and after 12 months of the participants' having access to the exception of Agewell Center facilities. The findings demonstrate that participation in the Center in itself was beneficial, with improved body composition and reduced cardiovascular risk in both groups (p < .05), and that this kind of community-based resource offers valuable potential for promoting protective behaviors and reducing health risk. However, a specific focus on identifying individual behavior change goals was required in order to achieve increased activity engagement (p < .05) and to bring about more substantial improvements in a range of health, diet, and physical function measures (p < .05).

The environment as a determinant of successful aging or frailty

The number of elderly persons is rising rapidly, and healthspan is a key factor in determining the well-being of individuals and the sustainability of national health systems. Environmental health is crucial for a "successful aging". Complex relationships between environmental factors and non-communicable diseases play a major role, causing or accelerating disabilities. Besides genetic factors, aging results from the concurrence of several environmental factors starting from early (i.e. in utero) life, able to increase susceptibility to diseases in adulthood, and to promote frailty in the elderly. In aged people, an unhealthy environment contributes to a fast and early decline and increases vulnerability. Exposure to pollutants facilitates the onset and progression of cardiovascular, respiratory, metabolic and neurologic diseases through direct effects and epigenetic mechanisms negatively affecting biological age. Healthy diet, healthy environment and constant physical activity could counteract, at least in part, the negative effects of environmental stressors. Almost all environmental factors generating detrimental effects on aging are modifiable, with relevant implications in terms of primary prevention measures potentially leading to decreased frailty, to an increase in the number of years lived without diseases or disability, and to a significant reduction in health expenditure.

Satisfaction with Life, Subjective Well-Being and Functional Skills in Active Older Adults Based on Their Level of Physical Activity Practice

Studies about the influence of physical activity on life satisfaction, functional ability and subjective well-being in physically active older adults without cognitive impairment are very few for the moment. Therefore, the aim of this research was to evaluate the life satisfaction, functional skills and subjective well-being of physically active older adults based on the level of activity practiced. The IPAQ (International Physical Activity), CUBRECAVI and LSIA (Life Satisfaction Index) scales were tested for a sample of 397 Spanish older adults between 61 and 93 years of age (M = 69.65; SD = 4.71). The results showed that those who performed high physical activity obtained higher scores in functional skills (p < 0.01) and in the activities of daily living (p < 0.01). In addition, subjective well-being (p < 0.01) and the functional autonomy of older adults (p < 0.01) were related to the level of physical activity that they practiced. In conclusion, it could be said that the older adults with a high level of physical activity have more functional skills and less difficulties performing the activities of daily living, and that they value their autonomy and health better.

An Overview of the Beneficial Effects of Exercise on Health and Performance

Life expectancy is steadily increasing in modern societies, and so are noncommunicable diseases such as cardiovascular diseases, diabetes, obesity, and cancer, accounting for more than 70% of all deaths globally. The costs associated with these diseases are enormous, but it has been estimated that the majority of these noncommunicable diseases are preventable. In addition to an unhealthy diet, tobacco use, and harmful use of alcohol, physical inactivity is a key risk factor. Consequently, physical activity is a logical remedy, and in this chapter an overview of the numerous beneficial effects of physical activity on health and performance is given.The chapter is divided into three parts: First, the basics of physical activity and exercise are discussed, for instance exercise classification, exercise intensity operationalization, energy supply, and the acute effects of exercise such as blood flow redistribution and increased cardiac output. In the second part, the effects of exercise on physical performance are summarized. Specifically, it is discussed how endurance, strength, power, and balance can be improved. This discussion includes recommendations regarding the type, intensity, and duration of the exercise leading to improvements in one of these aspects of physical performance, as well as the mechanisms causing these adaptations. In the third part, the beneficial effects of physical activity on physical and mental health are outlined, with particular attention to cardiovascular diseases, the metabolic syndrome, musculoskeletal diseases, mood, anxiety, depression, and dementia.It can be concluded that with adequate programming, regular physical activity is an effective way to improve physical performance, improve physical and mental health, and reduce the risk factors for many noncommunicable diseases such as cardiovascular diseases, metabolic syndrome, sarcopenia, osteoporosis, and depression. In contrast to medication, physical exercise has no negative side effects, costs very little, and targets many health issues at once. If the multitude of beneficial effects of regular exercise were to be combined in a single low-cost drug, it would be prescribed for almost all types of physical and mental health issues.

Energy Balance and Active Lifestyle: Potential Mediators of Health and Quality of Life Perception in Aging

The relationship between aging and perception of health and quality of life is complex and its mediation mechanisms need to be further explored. The purpose of this study was to investigate the mediating effects of total energy expenditure and intake, body mass, and body image dissatisfaction on the relationship between age and perception of health and quality of life. Forty-two senior athletes, 55 physically active, and 61 sedentary individuals (aged 55–84 years) were evaluated for total energy expenditure (EE), energy intake (EI), body mass index (BMI), absolute Body Dissatisfaction Index (BDIabx), and physical (PCS) and mental (MCS) health and quality of life perception. Multiple mediation analyses were applied to assess the relationship between age and PCS and MCS indices, through the mediators EE, EI, BMI, and BDIabx. For MCS, but not for PSC, the mediation analysis showed: (a) a direct effect of age; (b) a mediation path through EE, EI, BMI, and BDIabx; and (c) a positive total effect. The combination of positive and negative mediating effects influencing the mental health perception underlined that with advancing age, the maintenance of high levels of energy expenditure through physical activity could positively impact body image satisfaction and, in turn, mental health.

Going to Altitude with a Preexisting Psychiatric Condition

Psychiatric disorders have a high lifetime prevalence affecting about 30% of the global population. Not much is known about high altitude (HA) sojourns in individuals living with a psychiatric condition. This lack of scientific evidence contrasts with the anticipated increase in numbers of individuals with preexisting psychiatric conditions seeking medical advice on HA exposure. Not only are there risks associated with a HA climb, but physical activity in general is known to improve symptoms of many psychiatric disorder and enhance measures of mental well-being like quality of life and resilience. There are additional positive effects of alpine environments on mental health beyond those of physical activity. All individuals going to HA with a preexisting psychiatric condition should be in a state of stable disease with no recent change in medication. Specific considerations and recommendations apply to individual psychiatric disorders. During the HA sojourn the challenge is to separate altitude-related symptoms such as insomnia from prodromal symptoms of the underlying disorder (e.g., depressive episode) or altitude-related hyperventilation from panic attacks. In case an individual with preexisting anxiety disorder decides to go to HA there might be a predisposition toward acute mountain sickness (AMS), but it should always be considered that many symptoms of anxiety and AMS overlap. Any medication that is anticipated to be taken during ascent or at HA should be tested for compatibility with the psychiatric condition and medication before the trip.

Change in physical activity and health-related quality of life in old age-A 10-year follow-up study

The aim of the study was to examine the association between change in leisure-time physical activity (LTPA) and change in health-related quality of life (HRQoL) and symptoms of depression during a 10-year follow-up. This prospective study included 1036 men and women (mean age at baseline = 61.2 years) from the Helsinki Birth Cohort Study. Leisure-time physical activity was measured with a questionnaire, HRQoL with SF36 and depression symptoms with Beck's depression inventory (BDI). The association between the change in LTPA and change in HRQoL and BDI were investigated with sex-stratified general linear models adjusted for age, smoking, educational attainment, comorbidity score, and baseline value of outcomes. One standard deviation (SD) increase in LTPA was associated with increase in physical summary component of HRQoL in women (B = 0.7 unit, 95% CI = 0.1-1.3, P = 0.032) and in men (B = 0.8 unit, 95% CI = 0.2-1.5, P = 0.014). In women, the 1SD increase in LTPA was also associated with an increase in mental summary component score (B = 1.0, 95% CI = 0.3-1.7, P = 0.005) and a reduction in depressive symptoms (B = -0.7, 95% CI = -1.1 to -0.2, P = 0.003). In conclusion, increase in the volume of LTPA over a 10-year period in late adulthood was associated with improved HRQoL in both men and women, and also diminished depressive symptoms in women. The findings support the promotion of physical activity in later years to enhance HRQoL and mental well-being.

[The influence of activities on the quality of life of the elderly: a systematic review]

The scope of this study was to identify which activities or interventions cause changes in the quality of life of the elderly. It involved a systematic review of the literature in the Scopus, ISI Web of Science, Scielo, Lilacs, BDenf and PubMed databases. The key word for the Medical Subject Heading (MeSH) used was "quality of life," in combination with the terms of greatest interest: "elderly, motor activity, education." The research was conducted between July and August 2015 and included original works published between 2010 and 2015 in English, Portuguese and Spanish. The Cochrane strategy was also adopted for the preparation of the review. Twenty-seven articles were studied that compared the quality of life of the elderly before and after performing a physical, educational or mixed-type intervention. The main result obtained was that the general health, social function, physical role and satisfaction with life are the most influenced domains, whereby group physical activities are practiced the most. The conclusion drawn is that when carrying out activities of any kind, preferably adapted for age, there are changes in the quality of life of the elderly in a general manner, notably with an improvement in functional, mental and social aspects.

Physical Activity and Sports-Real Health Benefits: A Review with Insight into the Public Health of Sweden

Positive effects from sports are achieved primarily through physical activity, but secondary effects bring health benefits such as psychosocial and personal development and less alcohol consumption. Negative effects, such as the risk of failure, injuries, eating disorders, and burnout, are also apparent. Because physical activity is increasingly conducted in an organized manner, sport’s role in society has become increasingly important over the years, not only for the individual but also for public health. In this paper, we intend to describe sport’s physiological and psychosocial health benefits, stemming both from physical activity and from sport participation per se. This narrative review summarizes research and presents health-related data from Swedish authorities. It is discussed that our daily lives are becoming less physically active, while organized exercise and training increases. Average energy intake is increasing, creating an energy surplus, and thus, we are seeing an increasing number of people who are overweight, which is a strong contributor to health problems. Physical activity and exercise have significant positive effects in preventing or alleviating mental illness, including depressive symptoms and anxiety- or stress-related disease. In conclusion, sports can be evolving, if personal capacities, social situation, and biological and psychological maturation are taken into account. Evidence suggests a dose–response relationship such that being active, even to a modest level, is superior to being inactive or sedentary. Recommendations for healthy sports are summarized.

A cross-sectional study on the correlation between physical activity levels and health-related quality of life in community-dwelling middle-aged and older adults

This study aimed to evaluate the association between physical activity level and health-related quality of life in community-dwelling middle aged and older adults in Egypt. Between May and August 2017, a cross-sectional study of 184 middle-aged and older adults between the ages of 55 and 64 years old (129 males and 55 females) with a mean age of 58 ± 4.3 years old participated in this study. Study participants were classified into 3 groups based on their level of physical activity (walking duration); low level of physical activity (<150 minutes/week), moderate level of physical activity (150-300 minutes/week), and high level of physical activity (>300 minutes/week). The health-related quality of life (HRQoL) was calculated using the Euro-Quality of life-5dimensions-3 levels scale questionnaire (EuroQol-5D-3L). Spearman's correlation coefficient was performed to determine the correlation between the physical activity level and HRQoL scores in community-dwelling middle-aged and older adults. The results showed a significant correlation between the physical activity levels and HRQoL dimensions. Significant differences were observed in the HRQoL scores between high, moderate and low-physical activity groups (P < .05). The moderate and high-physical activity groups had significantly higher HRQoL scores in all dimensions than low-physical activity group. The low-physical activity group showed a high predominance of the chronic disease compared to the high and moderate physical activity groups. It was concluded that high and moderate levels of physical activity have a great positive relationship with the HRQoL in community-dwelling middle-aged and older adults in Egypt. Recommendations should be dedicated to supporting the active lifestyle among the different population, particularly middle-aged and older adults.

Is the Effect of Physical Activity on Quality of Life in Older Adults Mediated by Social Support?

Increasing evidence suggests positive associations between physical activity, social support, and quality of life in later life. However, the role of physical activity and social support in the influence on quality of life is unclear. In this viewpoint, definitions of central terms and key research findings on factors influencing quality of life in older adults are provided. We highlight the importance of both a physically active lifestyle and high social support in positively influencing quality of life. However, we question the direct effect of physical activity on quality of life and present data of a cross-sectional study to support the assumption that the effect of physical activity on quality of life might be influenced by perceived social support. In this cross-sectional study, self-reported physical activity, social support, and quality of life were assessed in a nonclinical sample of 100 adults aged between 60 and 80 years. Statistical analyses included correlation analyses and covariate-controlled mediation analyses. The results confirmed the research findings on positive correlations between all domains of quality of life and both physical activity and social support. Mediation analyses indicated that the effect of physical activity on all domains of quality of life was at least partially mediated by social support, when controlled for covariates. Based on the findings of published evidence and this cross-sectional study, a socially and physically active lifestyle is recommended for older adults to positively influence quality of life. However, the well-documented effect of physical activity on quality of might be an at least partially mediated effect by perceived social support. Practical and research-related implications of a potential indirect effect are discussed. Further prospective research is warranted to clarify the relationship between the variables.

The effect of physical activity in an alpine environment on quality of life is mediated by resilience in patients with psychosomatic disorders and healthy controls

OBJECTIVE

Physical activity (PA) in an outdoor environment has been shown to exert positive effects on mental well-being beyond those found for PA indoors. The specific effect of an alpine environment has not been investigated so far. Here we evaluate the association of PA in an alpine environment with resilience and quality of life (QOL) in patients with psychosomatic disorders and controls.

METHODS

194 patients with psychosomatic disorders (mostly somatoform disorder and major depressive syndrome) and 326 healthy controls were included in this web-based cross-sectional study. PA was scored using an adapted version of the Global Physical Activity Questionnaire including the environmental aspect (indoor, outdoor, alpine environment). Resilience was assessed using the Resilience Scale-13, QOL using the WHOQOL-BREF. Group comparisons, correlation and mediation analyses were performed.

RESULTS

Patients showed significantly lower levels of resilience (p < 0.001) and QOL (p < 0.001) compared to controls. PA in an alpine environment was associated with resilience (patients: r = 0.35, p < 0.001; controls r = 0.18, p < 0.001). There were no significant associations between PA in other environments (outdoor or indoor) and resilience. PA in all three environments correlated with subcategories of QOL. The effect of PA in an alpine environment on QOL was partly mediated by resilience in patients (68% of total effect mediated, p < 0.001) and controls (49% mediated, p = 0.006).

CONCLUSION

There is a positive effect of PA in an alpine environment on mental health beyond that of physical activity itself. Preventive and therapeutic programs should thus include physical activity, but also take additional benefits of natural environments into account.

Visualizing Physical Activity Patterns among Community-Dwelling Older Adults: A Pilot Study

Regular physical activity relates to physical and mental functioning in older people, and promoting physical activity has the potential to substantially reduce functional decline and improve well-being. Despite this, investigations of the physical activity quotient through participation in functional activities in everyday life have traditionally gained limited focus among older populations compared to leisure-time physical activity and exercise. Considering the accumulated evidence of the health benefits of low-intensity physical activity, exploring and measuring such activities in this population is highly relevant. The aim of this study was to visualize and describe older people’s physical activity patterns in daily life using a time-geographic approach in combination with the estimation of metabolic equivalents (METS). To exemplify the new method, a sample of nine retired men (65–82 years old, mean age 76.4 ± 5.8) with no homecare services from the municipality was recruited. In order to enable a visual analysis of the physical activity patterns in daily life, we developed the VISUAL-PA software, which is a visual analysis tool that includes METS to account for intensity and enables the analysis of distinct types and domains of physical activity. The VISUAL-PA software creates graphic outputs of physical activity patterns that enable the identification, visualization, and analysis of distinct types and intensities of physical activity in addition to sedentary behavior. The use of VISUAL-PA can contribute to a broader understanding of the complexity in physical activity patterns among older adults in terms of dimensions such as activity patterns and habits, domains, and intensity level. To strengthen the public health strategies that promote health and an active lifestyle, additional knowledge about physical activity patterns is necessary. Moreover, the visualization of physical activity can enable reflections on and awareness of activity habits and preferences, and thus facilitate behavior changes in older individuals.

Quality of life in older adults: Benefits from the productive engagement in physical activity

Background/objective

Productive engagement can be a strategy to reduce stress and chaos. Physical activity, a basic type of productive activity, could benefit older adults. Therefore, the purpose of this study was to explore how productive engagement in physical activity may influence older adults in maintaining their health-related quality of life when they live in a long-term care facility.

Methods

We used purposive sampling to recruit 163 participants from 14 long-term care facilities in Taiwan. Data were collected through individual interviews with a structured questionnaire. Descriptive statistics and independent t-test were used.

Results

The result demonstrated that the preferred type of physical activities for the older adults was similar after the relocation. Older adults with increasing productive engagement in physical activity reported better scores of Mental Component Summary, social and emotional role functioning than those with decreasing productive engagement in physical activity.

Conclusion

Older adults can have a positive perceived health-related quality of life by consistently or increasingly engaging in productive physical activity, especially when encountering a life event.

Gender differences in psychosocial predictors of self-perceived health status in the elderly: Evidence from a Brazilian community study

This article aims to identify the psychosocial factors associated with self-perceived health status in the Brazilian elderly population and to present differences related to gender. The data were collected by questionnaire, including sociodemographic and behavioral questions, and scales for psychological dimensions. Self-perceived health status is related to level of education, physical activity, and self-efficacy in the total population. Regarding gender differences, self-rated health status among men is related to education level and self-efficacy and in women to level of education, physical activity, social support, and self-efficacy. These results can inform future health promotion interventions.

Objectively measured physical activity and physical performance in old age

Background

physical performance is a key factor that determines how older people cope with daily tasks and maintain independency. There is strong evidence suggesting that physical activity (PA) is important in maintaining physical performance in old age. However, most studies have been done using self-reported PA. Our aim was to explore the association between objectively measured PA and physical performance in old age.

Methods

we studied 695 participants (mean age 70.7 years, SD 2.7) from the Helsinki Birth Cohort Study. Physical performance was assessed with the Senior Fitness Test (SFT) and PA with a multisensory activity monitor SenseWear Pro 3 Armband.

Results

total volume of PA was significantly associated with the overall SFT score (β = 0.08; 95% confidence interval: 0.07-0.10, P < 0.001). There were no significant differences between men and women. Both light and moderate to vigorous level of PA were positively associated with the overall SFT score, while sedentary time was negatively associated with the overall SFT score.

Conclusions

volume of objectively measured PA among older people was positively associated with the physical performance measured with a validated fitness test battery.

Physical Activity and Health Perception in Aging: Do Body Mass and Satisfaction Matter? A Three-Path Mediated Link

Although ageing people could benefit from healthy diet and physical activity to maintain health and quality of life, further understandings of the diet- and physical activity-related mechanisms that may cause changes in health and quality of life perception are necessary. The purpose of the study was to investigate the effect of eating attitudes, body mass and image satisfaction, and exercise dependence in the relationship between physical activity and health and quality of life perception in older individuals. Hundred and seventy-nine late middle-aged, (55–64 yrs), young-old (65–74 yrs), and old (75–84 yrs) senior athletes (n = 56), physically active (n = 58) or sedentary adults (n = 65) were submitted to anthropometric evaluations (body mass, height) and self-reported questionnaires: Body Image Dimensional Assessment, Exercise Dependence Scale, Eating Attitude Test, and Short Form Health Survey (Physical Component Summary [PCS] and Mental Component Summary [MCS] of and health and quality of life perception). Senior athletes, physically active, and sedentary participants subgroups differed (P<0.05) from each other in body mass index (BMI) and several components of body image and exercise dependence. Senior athletes showed, compared to their sedentary counterparts, further differences (P<0.05) in eating attitudes and in both PCS and MCS. Mediation analysis showed that the relationship between physical activity habit and MCS, but not PCS, was indirectly explained by a serial mediation chain composed of objective BMI and subjective body image (dis)satisfaction. Findings confirm the relevant role of physically active life habits for older individuals to perceive good physical and mental health. The novelty of the three-path mediated link between physical activity level and mental health perception suggests that the beneficial effect of a physically active lifestyle on weight control can positively impinge on the cognitive-emotional dimension of mental health by ensuring the maintenance, also at older age, of a satisfactory body image.

Long-term transportation noise annoyance is associated with subsequent lower levels of physical activity

Noise annoyance (NA) might lead to behavioral patterns not captured by noise levels, which could reduce physical activity (PA) either directly or through impaired sleep and constitute a noise pathway towards cardiometabolic diseases. We investigated the association of long-term transportation NA and its main sources (aircraft, road, and railway) at home with PA levels. We assessed 3842 participants (aged 37-81) that attended the three examinations (SAP 1, 2, and 3 in years 1991, 2001 and 2011, respectively) of the population-based Swiss cohort on Air Pollution and Lung and Heart Diseases in Adults (SAPALDIA). Participants reported general 24-h transportation NA (in all examinations) and source-specific NA at night (only SAP 3) on an ICBEN-type 11-point scale. We assessed moderate, vigorous, and total PA from a short-questionnaire (SAP 3). The main outcome was moderate PA (active/inactive: cut-off≥150min/week). We used logistic regression including random effects by area and adjusting for age, sex, socioeconomic status, and lifestyles (main model) and evaluated potential effect modifiers. We analyzed associations with PA at SAP 3 a) cross-sectionally: for source-specific and transportation NA in the last year (SAP 3), and b) longitudinally: for 10-y transportation NA (mean of SAP 1+2), adjusting for prior PA (SAP 2) and changes in NA (SAP 3-2). Reported NA (score≥5) was 16.4%, 7.5%, 3%, and 1.1% for 1-year transportation, road, aircraft, and railway at SAP 3, respectively. NA was greater in the past, reaching 28.5% for 10-y transportation NA (SAP 1+2). The 10-y transportation NA was associated with a 3.2% (95% CI: 6%-0.2%) decrease in moderate PA per 1-NA rating point and was related to road and aircraft NA at night in cross-sectional analyses. The longitudinal association was stronger for women, reported daytime sleepiness or chronic diseases and it was not explained by objectively modeled levels of road traffic noise at SAP 3. In conclusion, long-term NA (related to psychological noise appraisal) reduced PA and could represent another noise pathway towards cardiometabolic diseases.

How Obesity Affects Tendons?

Several epidemiological and clinical observations have definitely demonstrated that obesity has harmful effects on tendons. The pathogenesis of tendon damage is multi-factorial. In addition to overload, attributable to the increased body weight, which significantly affects load-bearing tendons, systemic factors play a relevant role. Several bioactive peptides (chemerin, leptin, adiponectin and others) are released by adipocytes, and influence tendon structure by means of negative activities on mesenchymal cells. The ensuing systemic state of chronic, sub-clinic, low-grade inflammation can damage tendon structure. Metabolic disorders (diabetes, impaired glucose tolerance, and dislipidemia), frequently associated with visceral adiposity, are concurrent pathogenetic factors. Indeed, high glucose levels increase the formation of Advanced Glycation End-products, which in turn form stable covalent cross-links within collagen fibers, modifying their structure and functionality.Sport activities, so useful for preventing important cardiovascular complications, may be detrimental for tendons if they are submitted to intense acute or chronic overload. Therefore, two caution rules are mandatory: first, to engage in personalized soft training program, and secondly to follow regular check-up for tendon pathology.

Physical Activity and Health-Related Quality of Life Among Community Dwelling Elderly

BACKGROUND

Physical activity (PA) and health-related quality of life (HRQoL) are important factors for optimal health in the elderly. Studying the association between PA and HRQoL is becoming more essential as the number of elderly people increases worldwide. This study assesses the association between PA and HRQoL among community dwelling elderly above 60 years old.

METHODS

The study included 115 women and 61 men (mean age: 68.15 ± 6.74 years) recruited from the community and from public centers for the elderly. Data were collected using a background characteristics questionnaire (BCQ), a physical activity socio-cultural adapted questionnaire (PA-SCAQ), and the EuroQuol-5Dimensions-5Levels (EQ-5D-5L) questionnaire. Between groups, comparisons were based on the PA-SCAQ by dividing the participants into three PA groups: low (n = 74), moderate (n = 85), and high (n = 17). Kruskal-Wallis tests were performed on the ordinal variables of the three PA groups to determine differences between the groups according to categorical variables such as gender, body mass index (BMI), and the prevalence of comorbid conditions. Mann-Whitney U tests were performed on the ordinal variables of the EuroQuol-5Dimensions (EQ-5D), and the independent sample t-test was performed on the EQ visual analogue scale (EQ-VAS). Spearman's rank correlation coefficient was used to examine the correlation between the EQ-5D and level of PA.

RESULTS

Values in all dimensions of HRQoL were significantly higher (P < 0.05) in the moderate and high PA groups compared with the low PA group. Significant correlations were recorded between the five dimensions of HRQoL and the level of PA (P < 0.001). The low PA group showed higher prevalence of hypertension (64%, P < 0.001) and diabetes (50%, P < 0.001).

CONCLUSION

There were strong associations between higher levels of PA and all dimensions of HRQoL. Therefore, adopting a PA lifestyle may contribute to better HRQoL among community dwelling elderly above 60 years old.
