A Person-Centered Perspective on Physical Activity-Related Barriers Perceived by Male Fluctuators 50 Plus: A Cross-Sectional Study.

Men aged 50 or older (50 plus) represent a hard-to-reach target group for health-enhancing physical activity (PA) interventions. However, a considerable percentage of men 50 plus do not entirely fail to achieve the PA milestones set by the World Health Organization (WHO) guidelines. They show fluctuating PA behavior, influenced by various barriers hindering or preventing regular PA participation. As "one-size-fits-all" behavioral change interventions are only partially effective in specific subgroups, it is essential to tailor PA promotion measures to the particular needs of male fluctuators 50 plus. The standardized questionnaire included validated instruments measuring participants' current stage of behavioral change, their perceived barriers to PA, questions on selected psychosocial correlates of PA, and sociodemographic variables. Out of 1,013 participants, 133 men (13.1%) classified themselves as fluctuators. Using a person-centered approach, we formed groups with similar intra-individual relevant barrier profiles using hierarchical cluster analysis (Ward method) followed by k-means clustering. We identified four clusters. Cluster 1 (n = 31) involves men predominantly perceiving physical constraints. Cluster 2 (n = 33) represents men lacking self-motivation and struggling with their weaker selves. Men in Cluster 3 (n = 51) primarily indicate professional and private obligations that prevent them from being physically active. Finally, men in Cluster 4 (n = 18) miss appropriate sports courses that meet their individual needs. Our findings support identifying individually tailored strategies designed to promote regular PA in male fluctuators 50 plus. Further research is required to determine the effectiveness of this approach in improving adherence to PA guidelines and corresponding health-enhancing effects for men 50 plus.

Association of meeting both muscle strengthening and aerobic exercise guidelines with prevalent overweight and obesity classes - results from a nationally representative sample of German adults.

OBJECTIVES: German national physical activity guidelines specify adults (≥18 years) should engage in at least: (i) 150 min of aerobic moderate-to-vigorous-intensity physical activity/week (MVPA); and (ii) muscle-strengthening exercise (MSE) 2 days/week. However, the relationship between MVPA and MSE and overweight/obesity has not been examined among German adults. Aim of this study was to examine whether meeting the guidelines for both MVPA and MSE is associated with a lower prevalence of overweight/obesity compared to meeting MVPA or MSE alone or none of them, among a nationally representative sample of German adults. METHODS: The cross-sectional study drew data from the 2014 German Health Update (GEDA) (n=22,822; ≥18 years). Physical activity (MVPA-MSE), height/weight, socio-demographic, health and lifestyle factors were assessed by self-report via validated questionnaires. Generalized linear models with Poisson regression were used to assess prevalence ratios of Body Mass Index-derived (BMI) overweight/obesity across categories of physical activity guideline adherence (met neither; MSE only; MVPA only; met both). RESULTS: Compared to other physical activity groups, meeting both the MVPA-MSE guidelines was associated with the lowest prevalence rate of overweight/obesity (Adjusted Prevalence Ratios [APR] range: 0.25-0.73). Associations between BMI and physical activity were strongest among Class II obesity (APR range: 0.25-0.45). The associations remained consistent after adjusting sociodemographic and lifestyle factors. CONCLUSIONS: Meeting the combined MVPA-MSE guideline, as suggested in the German national physical activity recommendations, showed the lowest overweight/obesity prevalence. Promoting uptake and adherence of both MVPA and MSE at the population level could help to reduce the public health burden of obesity.Highlights Meeting both muscle strengthening and aerobic exercise guidelines show the lowest overweight/obesity prevalence in a German representative sample of adults. Promoting uptake and adherence of both MVPA and MSE at the population level could help to reduce the public health burden of obesity.

[The Person Who Plays Handball Needs the Ball, the Contact and the Community - Changes in Sport Club Activities Due to the COVID-19 Pandemic and its Significance for Sports Clubs]. / "Der Mensch, der Handball spielt, braucht den Ball, den Kontakt und die Gemeinschaft" ­ Veränderungen im Sportangebot durch die COVID-19 Pandemie und deren Bedeutung für Sportvereine.

AIM: Sports clubs play an important role in the promotion of physical activity and health in Germany. Against the background of restrictions due to the COVID-19 pandemic, the present study explores the changes in sport activities and their significance for sports clubs. METHODS: We conducted 15 expert interviews with representatives of Bavarian sports clubs. The data were transcribed and evaluated inductively by means of thematic analysis. RESULTS: The clubs developed extensive activities to provide members with opportunities for sport and exercise even under the conditions of the COVID-19 pandemic. In general, the club members were understanding and positive towards the changes in the clubs. The participation in the newly created digital offers by the members seemed to differ from those in real courses. Nevertheless, the interviewees were skeptical about the long-term potential of digital sports offerings. Participants could miss the personal contact, the collective experience and team spirit when meeting only virtually. CONCLUSIONS: The efforts of the sports clubs to provide regular opportunities for sport and exercise during the COVID-19-pandemic underlines their importance for prevention and health promotion. From a public health perspective, changes in the offered activities may outlast the pandemic. However, further research is necessary.

The epidemiology of muscle-strengthening and aerobic physical activity guideline adherence among 24,016 German adults.

Despite the 2016 German "National Recommendations for Physical Activity and Physical Activity Promotion" stating that adults (≥18 years) should engage in: [a] ≥150 minutes of aerobic moderate-to-vigorous-intensity physical activity/week (MVPA); and [b] ≥2 days/week of muscle-strengthening exercise (MSE), there is limited research on the descriptive epidemiology on the adherence to these guidelines among German adults. This study describes the prevalence and correlates of physical activity guideline adherence among a nationally representative sample of German adults. Data were drawn from the 2014 German Health Update survey, collected via a combination of web-based and mail surveys. Self-reported physical activity levels were assessed using the previously validated European Health Interview Survey Physical Activity Questionnaire. Weighted prevalence levels of the sample meeting the aerobic MVPA (≥150 minutes/week), MSE (≥2 times/week), and combined MVPA-MSE guidelines were calculated. Poisson regressions were used to assess prevalence ratios for physical activity guideline adherence categories across sociodemographic and lifestyle-related variables. Out of 24,016 participants (response rate = 27.6%), aged ≥ 18 years, 45.3% (95% CI: 44.5%-46.0%), 29.4% (95% CI: 28.7%-30.1%), and 22.6% (95% CI: 21.9%-23.2%) met the aerobic MVPA, MSE, and combined guidelines, respectively. Population sub-groups less likely to meet the combined guidelines included those with poor self-rated health, being unemployed, low socioeconomic status, being a current smoker, and those being overweight or obese. Since ~ 80% of German adults do not meet the nationally recommended combined aerobic MVPA-MSE physical activity guidelines, there is a necessity for large-scale public health interventions promoting both aerobic MVPA and MSE.

[Cooperative planning of measures to promote physical activity : New paths for expanding capabilities-results from the Capital4Health research consortium]. / Kooperative Planung von Maßnahmen zur Bewegungsförderung : Neue Wege zur Erweiterung von Handlungsmöglichkeiten ­ Ergebnisse aus dem Forschungsverbund Capital4Health.

BACKGROUND: Despite various national and international political initiatives for promoting physical activity at the population level, the development of effective interventions for physical activity promotion remains a challenge. In this context, there is a growing interest in participatory approaches that actively involve central setting actors in the development of specific measures. AIM OF THE ARTICLE: This article reports on the experience made by the Capital4Health research consortium while using a participatory approach called "cooperative planning" to increase capabilities for physical activity across different age groups. RESULTS: Capital4Health employed the cooperative planning approach in the childcare, school, vocational training (car mechatronics and nursing), and community setting (with a focus on men 50+). While the central elements of the approach were implemented in all settings, planning processes varied significantly with respect to the spectrum of involved actors, the number of participants and sessions, the specific measures developed, the evaluation methods, and the effects achieved at an individual and systems level. CONCLUSION: From the perspective of the Capital4Health principal investigators, the preliminary empirical results from the different settings allow for the overall conclusion that the cooperative planning approach can work and generate health promotion impact in very different settings. However, it must (and can) be adapted to the respective setting, especially in relation to involving population groups. Actors' readiness for change is crucial, as physical activity does not always have top priority in settings. In this context, key individuals can make a decisive contribution to a project's success.

Muscle-strengthening exercise and sleep quality among a nationally representative sample of 23,635 German adults.

Regular physical activity is a key modifiable non-pharmacological treatment to enhance sleep quality, a key predictor of optimal health and wellbeing. Most of the evidence on physical activity and sleep quality is based on studies assessing the effects of aerobic moderate-to-vigorous physical activity (e.g. brisk walking, cycling, jogging). Emerging clinical evidence suggests that muscle-strengthening exercise (e.g. push-ups, using weight machines) may also be beneficial for sleep quality. However, since no studies have examined the associations between muscle-strengthening exercise with sleep quality among a large sample of community-dwelling adults, it is currently unknown how these findings translate to the population level. This study describes the associations between the weekly frequency of muscle-strengthening exercise and sleep quality among a nationally representative sample of German adults. Data were drawn for the 2014 German Health Update Survey (n = 23,635; ≥18 years). Validated survey items assessed muscle-strengthening exercise (times/week) and sleep quality (assessed via 4 point-scale: 'very poor' to 'good'). Poisson regression with robust error variance was used to calculate prevalence ratios of (PR) across weekly muscle-strengthening exercise frequency (None [reference]; 1, 2, 3-4 and ≥ 5 times/week), adjusting for potential confounders (e.g. age, sex, socioeconomic status, self-rated health, smoking, alcohol, aerobic physical activity). Compared with those reporting none, any muscle-strengthening exercise was associated with a reduced prevalence of 'poor' (PR range: 0.77-0.83) and 'very poor' (PR range: 0.57-0.70) quality sleep. Future health behavior modification strategies to enhance sleep quality at the population-level should consider promoting muscle-strengthening exercise.

How Does the Campus Environment Influence Everyday Physical Activity? A Photovoice Study Among Students of Two German Universities.

Background: Sedentary time is high among university students. Prolonged sitting time and reduced physical activity is linked to a number of health risks, therefore interventions to increase options for physical activity on campuses are of high public health relevance. Evidence about the influence of the campus environment on movement and sedentary behavior of students is scarce. This study explores how the structural and social environment of two University campuses are related to students' everyday physical activity. Methods: We used the photovoice method to get a thorough insight into students' daily life on campus. We recruited a total of 46 University students in two German cities (University 1: n = 22, University 2: n = 24). They were asked to take ≥15 photos of places and situations on their respective campus that facilitate or hinder them to be physically active. The pictures were discussed with the participants in 10 focus groups. Focus group discussions were audio-recorded, transcribed and analyzed using content analysis. Results: Both universities do not exploit their potential of fostering daily physical activity on campus, according to the photos and discussions of the participating students. The vast green spaces offer no cues for movement: easily accessible equipment for sports (fixed or mobile) is lacking, walkways are partially hidden, and the facilities discourage from cycling to and on campus. Social norms induce participants to keep sitting during lectures and learning time. It was also pointed out that indoor hallways and foyers could be put to better use with regard to physical activity. The Photovoice project raised the participants' awareness of how the context influences their movement behavior, and helped them come up with solutions to make physical activity easier for students of their respective universities. Conclusion: The studied campuses discouraged students from being physically active by missing out on opportunities-indoors and outdoors-for fostering movement, such as designating the greens for games or walks, or providing sufficient lockers for biking gear. The results can serve as a basis to plan custom-made public health interventions.

Effects of a Participatory School-Based Intervention on Students' Health-Related Knowledge and Understanding.

Introduction: The development of knowledge and understanding in relation to movement and health is a basic requirement to facilitate lifelong engagement in physical activity with its accompanying possible health benefits. To train teachers in applying adequate strategies, implementation studies have often shown little acceptance of traditional top-down approaches. Thus, the purpose of the Health.edu project was to develop, implement and evaluate effective and feasible measures addressing students' health-related knowledge and understanding (HKU) in physical education (PE) via a participatory approach. Materials and Methods: For evaluation, a controlled pre-post-test study with 233 students from eight different secondary schools in Germany was carried out. Four schools (with two PE teachers at each school) comprised the intervention group and they participated in a 1-year participatory planning process to conceptualize and implement evidence-based PE lessons addressing students' HKU. Control schools carried out their regular PE lessons. Evaluation followed a mixed-methods research design, assessing program implementation via written documentary technique as well as program effectiveness using a standardized questionnaire. Results: Results show a significant intervention effect on students' HKU with a medium effect size. However, due to the participatory process, there were considerable differences between the intervention schools that were involved. Student's HKU improved most in schools where program implementation corresponded to relevant principles of fostering HKU. Discussion: The present study purposefully dispensed with any structured intervention programs for PE teachers to follow. The results show the potential effects of this participatory approach to strengthen student's HKU. However, the participatory planning does not always work in the intended manner, emphasizing that numerous contextual factors influence the implementation process.

Capacity Building in Community Stakeholder Groups for Increasing Physical Activity: Results of a Qualitative Study in Two German Communities.

Community capacity building is an essential approach for health promotion, combining a participatory approach with the view to community ownership. Little research focuses on practical capacity building strategies and monitoring. Our paper looks into involving stakeholders in facilitated group discussions as a specific strategy for fostering capacity building processes. These processes focused on physical activity (PA) promotion in two German communities (ACTION4men). Along the dimensions of capacity building suggested in literature (e.g., problem solving, resource mobilization, leadership), we implemented two participatory stakeholder groups (1/community). These groups were motivated to develop and implement PA interventions for men >50 years. For measuring capacity building processes, a semi-standardized monitoring instrument was used to document all group meetings. Additionally, we conducted semi-standardized interviews with group participants and drop-outs to capture their perspectives on capacity building. All documents were analyzed using thematic analysis. We successfully established stakeholder groups that planned and implemented a range of local measures meant to increase PA among older men. In one community, the process was sustainable, whereby the group continued to meet regularly over years. Capacity building was successful to a certain degree (e.g., regarding participation, problem assessment, and resource mobilization), but stalled after first meetings. Capacity building processes differed between the two communities in terms of leadership and sustainability. The developed interventions mainly addressed the access to organized sport courses, rather than tackling walkability or active transport. The theoretical capacity building approach was successful to develop and implement programs aimed at promoting PA. The actual capacity building processes depend upon the composition of stakeholder groups and inherent power relations.

ACTION for Men: Study Protocol of a Community Capacity Building Intervention to Develop and Implement Gender-Sensitive Physical Activity Programs for Men 50 Plus.

Introduction: Capacity building for health promotion is a relevant precondition for sustainable, health-related changes in community settings. So far, there are few evidence-based recommendations about how to implement and evaluate community capacity building approaches. ACTION for men (A4M) is a project designed to build and evaluate capacities for health promotion in three rural communities in Bavaria, Germany, via a participatory approach including multiple community stakeholders. The project specifically aims at improving physical activity (PA) in men over 50 years of age (50 plus). Methods and Analysis: As a strategy to build the communities' capacities, we set up stakeholder groups in so far two communities. Those stakeholder groups will be facilitated over a period of 1-3 years. In regular meetings, the group members will be motivated to actively participate in planning and implementing PA programs for men 50 plus. The facilitation will systematically address key domains of community capacity (e.g., critical awareness, problem assessment, resource mobilization). The evaluation of the capacity building processes will be carried out using a mixed-methods design. Evaluation instruments consist of structured documentations and face-to-face interviews with stakeholder group participants (and drop-outs) as well as a pre-post-test using a standardized questionnaire in order to detect activity-related changes in men 50 plus from the involved communities. In community three, we will conduct the same procedure with a delay of 6 months. Discussion: Building community capacity for health promotion programs is the primary aim in A4M, and thus differs from previous research in which capacity is mostly a means to an end or an "incidental" result of a health promotion program. Therefore, A4M is expected to deliver important findings about how to implement and evaluate capacity building processes for health promotion, as well as how to address physical activity in community settings.

Muscle-strengthening exercise and depressive symptom severity among a nationally representative sample of 23,635 german adults.

BACKGROUND: There is strong epidemiological evidence that physical activity is associated with lower likelihood of depression. Yet, most existing large population studies have investigated aerobic physical activity (e.g. walking/running), with few epidemiological studies examining the association between muscle-strengthening exercise (MSE; push ups, using weight machines) with depression. The aim of this study is to examine associations between MSE and depressive symptoms among a representative sample of German adults. METHODS: Cross-sectional analyses were conducted on the 2014 German Health Update. Validated questionnaires were used to assess MSE and depression symptom severity (eight-item Personal Health Questionnaire Depression Scale). Generalized linear models with Poisson regression with a robust error variance were used to assess prevalence ratios of depression symptom severity (mild, moderate, moderately severe/severe) across weekly MSE frequency (None [reference]; 1, 2, 3-4 and ≥5), adjusting for potential cofounders (e.g. age, sex, socioeconomic status, self-rated health, smoking, hazardous alcohol consumption, aerobic exercise). RESULTS: Data were available on 23,635 adults (≥18 years). When compared with those reporting no MSE, for all levels of depressive symptom severity, there were reduced prevalence ratios across all MSE frequencies. Compared to the higher MSE frequency groups (3-≥5 times/week), the prevalence ratios (range: 0.53-0.85) were similar among lower frequency groups (1-2 times/week) (range: 0.46-0.85). All associations remained after adjustment for sociodemographic, lifestyle characteristics and aerobic physical activity. LIMITATIONS: Findings may be biased by the self-reporting of MSE and depressive symptom severity. CONCLUSION: Any increase in MSE at the population-level may be beneficial for the prevention and treatment of depression.

The relationship between physical activity, fitness, physical complaints and BMI in German adults - results of a longitudinal study.

OBJECTIVES: This study's aims were to describe the development of physical activity, physical fitness (PF), subjective (physical complaints (PC)) and objective (Body mass index (BMI)) health measures and to examine the relationship between the development trajectories. In addition, the study also aimed to assess the influence of sociodemographic determinants (age, sex, socioeconomic status (SES)) in German adults over a period of 18 years. METHODS: The longitudinal study population comprises of 721 men and women, aged 33-76 years over the study period. There was self-report of physical activity and PC and testing of physical fitness and BMI in each study year (1992, 1997, 2002 and 2010). Latent growth curve models were used to analyse the development. RESULTS: Physical activity slightly increased while fitness, PC and BMI worsened over the course of 18 years. Sex, age and SES play important roles concerning physical activity, fitness and health. Several integrative associations could be detected between physical activity, fitness, PC and BMI as well as their trajectories. In particular, high initial levels of physical activity and fitness protect from high PC and BMI.The slope of physical activity was not significantly associated with slopes of fitness, PC and BMI. However, increase of fitness resulted in decrease of PC. CONCLUSIONS: A general positive development regarding the amount of physical activity could be detected. However, if it is only an unsystematic increase of physical activity, this is not in itself enough to achieve health benefits. The strengthening of fitness should be focused when increasing physical activity, since only then a health benefit is possible.

Different Types of Physical Activity and Fitness and Health in Adults: An 18-Year Longitudinal Study.

Objective. The aim of this study is to examine the relationship between different types of daily life physical activity (PA) and physical fitness (PF) and health throughout adulthood. Methods. A total of 723 men and women, aged 28-76 years, participated 1681 times during four measurement points from 1992 to 2010 in this study. We assessed self-reported PA, anthropometrics, physical health status (HS), and PF in each study year. Hierarchical linear modeling (HLM) was used to analyze the measures. Results. PF and HS worsened with increasing age while sports activity (SA) declined. The modeling showed that sex, age, and SES play important roles concerning PA, PF, and HS. Athletes show higher HS and HF than nonathletes. Habitual activity (HA) also showed a positive relationship with PF and HS, but effects were lower than for SA. Work related activity (WRA) showed no meaningful relationship with PF or HS. Conclusions. Comparable amounts of PA can lead to different effects on PF or HS. Our findings underline the importance of contexts, content, and purposes of PA when health or fitness benefits are addressed. Simply moving your body is not enough.
