Why are some groups physically active and others not? A contrast group analysis in leisure settings

Level and limitations of physical activity in patients with excess body weight or diabetes

Physical activity (PA) is recommended to prevent or treat many diseases, but various factors may limit it. We analyse the level of PA and the barriers to undertaking it. Patients aged 18-64 with diabetes or at least overweight completed the following questionnaires: International Physical Activity Questionnaire (IPAQ) and Accompanying Survey (AS). For statistical analysis, non-parametric Mann-Whitney U, χ2-Pearson, correspondence analysis and meta-analysis (OR with ±95% CI) were used, and α=0.05 was assumed. Of 191 sets of questionnaires were analysed (67% from women). The median (MD) age for the group was 50.5 years, MD for metabolic equivalents (METs): 2079 (MET-min/week); 16.23% of subjects scored insufficient, 46.07% sufficient and 37.7% high PA according to the IPAQ scale. A relationship between the IPAQ and PA level results from the AS was confirmed (χ2; p=0.00047). The most common reasons indicated for not taking up PA were lack of time due to professional work (49%) and additional duties (32%) as well as fatigue from daily duties (44%). Participants <45 years were more likely to indicate additional duties (p=0.013), participants >45 years illnesses (p=0.04) and people with BMI (body mass index) ≥30 kg/m2, 'fatigue from daily duties' (p=0.019) as an obstacle to undertaking PA. 'Lack of suitable conditions to undertake PA' was indicated more often by patients with primary education (p<0.01), diabetes (p=0.037), after myocardial infarction (p=0.039) and those under psychiatric treatment (p=0.039). Women more often declared a lack of motivation (p=0.018). Residents of big cities and those with BMI ≥30 were more likely to assess their PA as 'insufficient' (p=0.0260 and p=0.0081, respectively). The overwhelming number of respondents who were in the age of professional activity had a sufficient level of PA. The most common barriers to undertaking PA were lack of time and fatigue, related to both work and non-work activities, but specific barriers were also found for women and patients with various diseases.

Patterns of physical activity among nursing home residents before and during the Covid 19 pandemic-a systematic observation

BACKGROUND

The Covid-19 outbreak in spring of 2020 posed an array of challenges for nursing homes, including promoting resident physical activity (PA). Given the diversity of factors affecting resident PA, we explored how activity patterns outside weekly-scheduled structured activities changed during the pandemic and what factors promoted or inhibited PA during the pandemic.

METHODS

We conducted systematic direct observations over 823.5 h in eight nursing homes in Southern Germany in 2020 and 2021.

RESULTS

In 2020, 84.7% of person observation units were classified as sedentary (average activity level: 1.14 MET). In 2021, the percentage increased to 91.6% of observed person units (average activity level: 1.08 MET) (t = 6.947; p = .000). According to tree classification, influencing factors of PA included mealtime and daytime in 2020 and 2021, as well as presence of men residents only in 2020 and guided low threshold activities in 2021.

CONCLUSIONS

Nursing homes constitute highly sedentary places-an issue exacerbated by access restrictions for external activity experts and significant others as well as behavioural restrictions for residents during the Covid-19 pandemic. Staff could not compensate due to existing time restraints and lack of training in PA promotion. Based on our findings, we recommend future studies to develop feasible and resource-low activities to be integrated into the daily routines of nursing homes.

The detection of self-group conflicts in exercise behaviors differs with social network centrality: ERP evidence

BACKGROUND

The influence of social norms on exercise behaviors has been explored in studies over the years. However, little is known about whether an individual's role (central or peripheral) in his or her social network, which is associated with social skills, could shift his or her susceptibility to normative effects on exercise behaviors. To that end, event-related potentials (ERPs) were recorded to examine the underlying cognitive mechanism of the effects of network centrality on normative social influence.

METHODS

We manipulated network centrality by assigning participants to exercise support groups, with group members who were their nominated friends (high centrality) or nonnominated classmates (low centrality). Participants were asked to evaluate their willingness to engage in various exercises, after viewing discrepant group ratings (peer influence) or not viewing (no-influence).

RESULTS

Peer influence evoked a larger negative-going feedback-related negativity (FRN) wave, which was linked to automatic social conflict detection, and a larger positive-going P3 wave, which was linked to subsequent conformity behavioral changes. However, effects on the FRN, not the P3, were observed only in the high-centrality group.

CONCLUSION

Our results highlight the important roles of network centrality in encoding self-group exercise attitude discrepancy rather than in decision-making regarding exercise attitude adjustments. Interventions aimed at promoting exercise behaviors should be considered in a broader social environmental framework.

Social isolation is a direct determinant of decreased home-cage activity in mice: A within-subjects study using a body-implantable actimeter

NEW FINDINGS

What is the central question of this study? It is generally recognized that social isolation is associated with physical inactivity; however, is social isolation a direct determinant of decreased physical activity? What is the main finding and its importance? We conducted a within-subjects experiment with the aid of a body-implantable actimeter. Our results clearly demonstrated that social isolation decreased home-cage activity in mice. This might have resulted from increased immobility and decreased vigorous activity, suggesting that avoiding social isolation is important to preventing physical inactivity.

ABSTRACT

An inactive lifestyle can negatively affect physiological and mental health. Social isolation is associated with physical inactivity; however, it remains uncertain whether social isolation is a direct determinant of decreased physical activity. Hence, we assessed whether social isolation decreases home-cage activity using a within-subjects design and examined the effects of social isolation on hippocampal neurogenesis in mice. This study used a body-implantable actimeter called nanotag®, which enabled us to measure home-cage activity despite housing the mice in groups. We first examined the influence of the intraperitoneal implantation of nanotag® on home-cage activity. Although nanotag® implantation decreased home-cage activity temporarily, 7 days post-implantation, it recovered to the same level as that of control (non-implanted) mice, suggesting that implantation of nanotag® does not have a negative influence on home-cage activity if mice undergo a 1-week recovery period after implantation. In the main experiment, after the 1-week baseline measurement performed while in group housing, the mice were placed in a group or in isolation. Home-cage activity was measured for an additional 4 weeks. Home-cage activity in isolated mice during the dark period decreased by 26% from pre-intervention to the last week of intervention. Furthermore, the reduction in the number of 5-minute epochs during which the activity count exceeded 301 (an index of vigorous activity) was significantly larger for isolated mice. Contrary to expectations, social isolation did not impair hippocampal neurogenesis. Our results demonstrate that social isolation is a direct determinant of decreased physical activity, possibly because of reduced vigorous physical activity. This article is protected by copyright.

BaSAlt - A mixed-methods study protocol on setting-based physical activity promotion and counseling in nursing homes

Introduction

Physical activity (PA) is a major contributor to healthy aging. However, physical inactivity is prevalent among the elderly in Germany, particularly in institutionalized settings such as nursing homes. This paper aims to describe the study objectives, design, methods, assessment types, collection schedules and considerations for analyzing the data within the BaSAlt study on facilitators and barriers for PA promotion in nursing homes.

Methods

We designed the BaSAlt study as a participatory intervention study with multiple measurement points in six to eight nursing homes with a total of approx. 200 residents using four main modules: (1) setting-level analysis of physical activity patterns, physical activity-related climate and physical activity-related interaction with ‘significant others,’ and organizational facilitators and barriers to physical activity, (2) physical-activity related individual-level analysis of objective and self-reported physical activity and sedentary behavior, a geriatric assessment with established procedures, assessment of people's activity and health biographies (biographical mapping) as well as their motivational, subjective well-being and distress status, and (3) a counseling module that integrates counseling at the setting level as well as individual physical activity counseling for residents. In module (4) evaluation, the effects of integrated counseling with regard to the implementation of PA promotion strategies are analyzed.

Discussion

This study will extend our knowledge of physical activity promotion in German nursing homes. Its findings will inform governmental authorities, care professionals, and academics on how to reach a particular group, characterized by inactivity, multimorbidity, and a high prevalence of dementia, residing in nursing homes, a setting that will gain further relevance in the future.

Analysis of the Structural Relationship of Sports Participation and Ego-Resilience in the Health-Promoting Behavior of Korean Adolescents during the COVID-19 Pandemic

Background:

We aimed to verify the structural relationship between sports participation, ego-resilience, and health-promoting behavior of Korean adolescents in a pandemic situation.

Methods:

In Nov 2020, an online survey was conducted with 751 adolescents in Korea. The data obtained through the survey were analyzed in several ways, including frequency, reliability, confirmatory factor, descriptive statistical, and path analyses.

Results:

Sports participation had a positive effect on ego-resilience and health-promoting behavior, while egoresilience has a positive effect on health-promoting behavior. Overall, sports participation directly affects health-promoting behavior and that an indirect effect occurs through ego-resilience.

Conclusion:

Educational institutions such as schools and the Korea Offices of Education should devise various measures so that adolescents growing up in a global pandemic situation can strengthen their health-promoting behavior by securing ego-resilience through participation in various sports.

Leveraging technology to move more and sit less

One of the major changes in the updated physical activity (PA) guidelines is the recommendation for adults to simply move more and sit less throughout the day. This recommendation comes during a time of proliferation and advancement of personal health technologies that allow adults greater access to interventions to increase PA. Wearable activity monitors provide direct feedback of activity levels allowing users to reach PA targets throughout the day. Gamification of these and other devices can engage users and sustain their motivation to increase PA, along with the formation of social networks through social media platforms. This review will discuss and present an overview of current technologies that can be leveraged to increase PA in adults. Specific attention will be paid to wearable activity monitors, gamification and social network platforms that can help adults increase and sustain their PA levels to improve their overall health.

Reliability and Validity of a Culturally Adaptive Version of the International Physical Activity Questionnaire in Indian Subcontinent: A Cross-sectional Study

BACKGROUND

Physical activity (PA) is one of the prime public health problems occurring globally. Regular PA is associated with a decrease in all-causes of mortality irrespective of gender. The study was conducted to investigate the validity and an aspect of reliability of a modified version of the International Physical Activity Questionnaire (IPAQ) in the Indian subcontinent (InS).

METHODS

Cross-sectional study, to evaluate the validity and reliability of the InS IPAQ-LF compared with a range of biological variables. In total, 198 participants (50% women) with a mean age of 35.6 (SD = 10.3) years selected from neighborhoods with variable socioeconomic status and PA.

RESULTS

The InS IPAQ-LF demonstrated good test-retest reliability for total PA (Intraclass correlation coefficient [ICC] =0.79, 95% CI 0.65 to 0.82), occupational PA (ICC = 0.77, 95% CI 0.68 to 0.82), active transportation (ICC = 0.82, 95% CI 0.75 to 0.87), and vigorous-intensity activities (ICC = 0.82, 95% CI 0.76 to 0.87). Reliability was substantially higher for total PA (ICC = 0.80), occupational PA (ICC = 0.78), leisure-time PA (ICC = 0.75), and active transportation (ICC = 0.80) in men than in women, but domestic PA (ICC = 0.38) and sitting time (ICC = 0.71) demonstrated more substantial reliability coefficients in women than in men.

CONCLUSIONS

The InS IPAQ-LF demonstrated considerate evidence of test-retest reliability and may be valid for evaluating context specific PA mannerisms of adults in InS.
