Abstract Background The use of wearable sensor technology to collect patient health data, such as gait and physical activity, offers the potential to transform healthcare research. To maximise the use of wearable devices in practice, it is important that they are usable by, and offer value to, all stakeholders. Although previous research has explored participants’ opinions of devices, to date, limited studies have explored the experiences and opinions of the researchers who use and implement them. Researchers offer a unique insight into wearable devices as they may have access to multiple devices and cohorts, and thus gain a thorough understanding as to how and where this area needs to progress. Therefore, the aim of this study was to explore the experiences and opinions of researchers from academic, industry and clinical contexts, in the use of wearable devices to measure gait and physical activity. Methods Twenty professionals with experience using wearable devices in research were recruited from academic, industry and clinical backgrounds. Independent, semi-structured interviews were conducted, audio-recorded and transcribed. Transcribed texts were analysed using inductive thematic analysis. Results Five themes were identified: (1) The positives and negatives of using wearable devices in research, (2) The routine implementation of wearable devices into research and clinical practice, (3) The importance of compromise in protocols, (4) Securing good quality data, and (5) A paradigm shift. Researchers overwhelmingly supported the use of wearable sensor technology due to the insights that they may provide. Though barriers remain, researchers were pragmatic towards these, believing that there is a paradigm shift happening in this area of research that ultimately requires mistakes and significant volumes of further research to allow it to progress. Conclusions Multiple barriers to the use of wearable devices in research and clinical practice remain, including data management and clear clinical utility. However, researchers strongly believe that the potential benefit of these devices to support and create new clinical insights for patient care, is greater than any current barrier. Multi-disciplinary research integrating the expertise of both academia, industry and clinicians is a fundamental necessity to further develop wearable devices and protocols that match the varied needs of all stakeholders.

Recommendations For Assessment

UNSTRUCTURED Although it is becoming increasingly popular to monitor parameters related to training, recovery, and health with wearable sensor technology (wearables), scientific evaluation of the reliability, sensitivity, and validity of such data is limited and, where available, has involved a wide variety of approaches. To improve the trustworthiness of data collected by wearables and facilitate comparisons, we have outlined recommendations for standardized evaluation. We discuss the wearable devices themselves, as well as experimental and statistical considerations. Adherence to these recommendations should be beneficial not only for the individual, but also for regulatory organizations and insurance companies.

Introduction. Physical activity is known to be an important factor influencing health throughout human life. This issue has become crucial for public health due to the aging of the population in both developed and developing countries. Aim. is to present a literature review on the forms of physical activity undertaken by the elderly, as well as on issues related to physical activity and the population aging. Material and methods. The study was prepared on the basis of a review of Polish and foreign literature. The following databases and data sources were used: EBSCO, ScienceDirect and Google Scholar. An additional source of data were the websites of the Central Statistical Office. Strictly defined key phrases were used during the collection of literature. The work has been divided into thematic subsections on the aging of the society, the impact of physical activity on health and the main topic, i.e. forms of physical activity selected by the elderly. Analysis of the literature. The number of elderly people in Polish society has increased by almost 3.7 million over three decades. Therefore, an important topic is prophylaxis aimed at increasing the number of days in good health, largely covering the broadly understood activation of the elderly. The available data indicate that only 12% of elderly people undertake physical activity once a week. The most common form of spending free time actively is walking (as many as 73% of people in this population declare this form of physical activity in one of the presented studies). Conclusion. Organized forms of physical activity are undertaken much less frequently by the analyzed age group mainly due to financial limitations and limited availability of sports infrastructure.

Background and objective: Managing the decrease in physical function in the elderly is a major task in aging societies globally. Here, we aimed to compare the physical function and metabolic syndrome (MetS) risk factors according to levels of physical activity (PA). Material and methods: We measured PA in 77 elderly Korean men (74.21 ± 6.26 years old) with an accelerometer and recorded body composition, physical function, and MetS-related risk factors. Participants were divided into three groups based on daily moderate-vigorous physical activity (MVPA): low (under 60 min), middle (60-120 min), and high (over 120 min). The groups were compared using a one-way analysis of variance and the Scheffe post hoc test. Odds ratios (OR) were calculated by logistic regression analysis. Results: Significant differences were found between the groups for sedentary behavior time (P < 0.001), light PA (P < 0.05), moderate PA (P < 0.001), vigorous PA (P < 0.05), and total energy expenditure (P < 0.001). The high PA group showed a significantly lower percentage of body fat and fat mass and higher muscle mass than did the low and middle PA groups (P < 0.05). The 6-min walk test was significantly better in the high PA group than in the low and middle PA groups (P < 0.05). Grip strength and the Berg balance scale were also significantly better in the high PA group (P < 0.05). Bone mineral density (BMD) and high-density lipoprotein cholesterol (HDL-C) were significantly higher in the high PA group than in the low PA group (P < 0.05). Systolic blood pressure (SBP) was significantly higher in the middle PA group than in the low PA group (P < 0.05). Participants with more than three MetS criteria showed an OR of 0.09 (95% confidence interval 0.01-0.82) in the high PA group as compared with the low PA group (P < 0.05). Conclusions: Moderate-vigorous physical activity of more than 120 min daily showed better physical function and lower OR of MetS than did lower MVPA levels in elderly Korean men.

Peningkatan jumlah lansia setiap tahunnya harus dijadikan perhatian, akibat adanya peningkatan jumlah lansia masalah yang dihadapi akan menjadi semakin kompleks, salah satunya adalah masalah yang berkaitan dengan gejala penuaan. Menurunnya kapasitas intelektual berhubungan erat dengan fungsi kognitif pada lansia. Aktivitas fisik diidentifikasi sebagai salah satu faktor yang mempengaruhi fungsi kognitif. Aktivitas fisik bermanfaat untuk lansia sebagai pencegahan dan demensia. Penelitian ini merupakan penelitian analitik observasional dengan menggunakan pendekatan cross sectional. Penelitian dilakukan di yayasan sosial Panti Wredha Salib Putih Salatiga pada bulan Juni 2018. Populasi dalam penelitian ini adalah lansia yang berumur ?60 tahun. Subjek pada penelitian ini berjumlah 16 responden. Variabel independen dalam penelitian ini adalah aktivitas fisik yang dinilai dengan menggunakan instrument GPAQ. Sedangkan variabel dependen dalam penelitian ini adalah fungsi kognitif yang dinilai dengan instrument MMSE. Terdapat 4 orang (25%) yang masuk dalam kategori fungsi kognitif normal dengan kategori aktifitas fisik sedang 1 orang dan aktifitas berat 3 orang, kemudian yang termasuk dalam kategori gangguan fungsi kognitif ringan sebanyak 11 orang (68,75%), dengan kategori aktifitas fisik sedang 8 orang dan aktifitas ringan 3 orang. Sedangkan yang termasuk dalam kategori gangguan fungsi kognitif berat, terdapat 1 orang (6,25%) dengan kategori aktifitasnya ringan. Taraf signifikansi antar variabel tingkat aktifitas fisik dan fungsi kognitif pada lansia adalah p=0.007 atau p<0,05, sehingga dapat disimpulkan ada  hubungan antara tingkat aktifitas fisik dengan fungsi kognitif pada lansia.   Increasing the number of elderly people every year should be a concern, due to an increase in the number of elderly problems faced will become increasingly complex, one of which is a problem related to the symptoms of aging. Decreased intellectual capacity is closely related to cognitive function in the elderly. Physical activity is identified as one of the factors that influence cognitive function. Physical activity is beneficial for the elderly as prevention and dementia. This study was an observational analytic study using a cross sectional approach. The study was conducted at the social foundation nursing home in the white cross in June 2018. The population in this study was elderly aged ≥60 years. The subjects in this study were 16 respondents. The independent variable in this study is physical activity that is assessed using the GPAQ instrument. While the dependent variable in this study was cognitive function which was assessed by the MMSE instrument. There are 4 people (25%) who fall into the category of normal cognitive function with moderate physical activity categories 1 person and heavy activities 3 people, then those included in the category of mild cognitive function disorders are 11 people (68.75%), with the category of physical activity being 8 people and 3 light activities. While those included in the category of severe cognitive function disorders, there is 1 person (6.25%) with a mild activity category. The significance level between the level of physical activity and cognitive function in the elderly is p = 0.007 or p <0.05, so it can be concluded that there is a relationship between the level of physical activity and cognitive function in the elderly.

Background: A decrease in the physical activity level in old age is common, which results in an increase in the number of falls and chronic conditions. Associated with that occurs the decline in motor skills as a result of the deficit in the interaction of cognitive and motor processes. Physical activity level can be associated differently with each motor domains. Objective: We analyzed the relationship between physical activity level and motor aptitude, and to identify which motor domains were most sensitive to detect insufficiently active level in older adults. Methods: Participated in the study 385 elderly people of both sexes. For the evaluation of the subjects were adopted the International Questionnaire on Physical Activity and the Motor Scale for Older Adults. Results: The majority of the elderly were active. In the comparison of motor aptitude between active and insufficiently active (IAC) elders a significant difference was found in the Global Coordination, Balance, Body Scheme and General Motor Aptitude. From the analysis of the area under the curve (AUC), we verified that these domains also were the ones that presented adequate diagnostic accuracy to identify IAC elderly. Besides that active elderly have presented the General Motor Aptitude classified within normality while the IAC below the normal. Conclusion: Our data suggest that IAC older adults present lower motor aptitude than the active elderly, especially in the domains of Global Coordination, Balance, Body Scheme and General Motor Aptitude, and that these domains were sensitive to indicate IAC older adults.

Abstract Background Few previous cohorts have studied the different type of physical activities and the degree of cognitive decline. The objective of this work was to analyze the leisure, domestic and professional activities with mild and moderate cognitive disorders in older people living in community. Methods The study used data from the longitudinal and observational study, FrèLE (FRagility: Longitudinal Study of Expressions). The collected data included: socio-demographic variables, lifestyle, and health status (frailty, comorbidities, cognitive status, depression). Cognitive decline was assessed by using: MMSE (Mini-Mental State Examination) and MoCA (Montreal Cognitive Assessment). MoCA was used with two cut-offs (26 and 17) so as to define mild and moderate cognitive disorders Physical activity was assessed by the PASE (Physical Activity Scale for the Elderly), structured in three sections: leisure, domestic and professional activities. Spline and proportional hazards regression models (Cox) were used to estimate the risk of cognitive disorders. Results At baseline, 1623 participants were included and the prevalence of cognitive disorders was 6.9% (MMSE) and 7.2% (MoCA), mild cognitive disorders was 71.3%. The mean age was 77 years, and 52% of the participants were women. After a 2 years long follow-up, we found 6.9% (MMSE) and 6% (MoCA) cognitive disorders on participants. Analyses showed that domestic activities were associated to cognitive decline (HR = 0.52 [0.28-0.94] for MMSE and HR = 0.48 [0.28-0.80] for MoCA). No association were found with leisure and professional activities, and no spline were significant with mild cognitive disorders. Conclusions Analysis showed a relationship between cognitive disorders and type of physical activity, thanks to the use of specific questionnaire of elderly and two global test of cognition. These findings will contribute to the debate on the beneficial effects of physical activity on cognition. Key messages This work allowed to compare two test of cognition and their link with physical activity. It contributes to the debate on the beneficial effects of physical activity on cognition. The work allowed us to see the effect of the different types of physical activity and the impact of the statistical method on the results.
