Objectives: Poor cardiorespiratory fitness (CRF) and high body mass index (BMI) increased the risk of developing metabolic Syndrome (MetS) mostly in Caucasians. However, the sex-specific combined association of CRF and BMI on MetS considering health-related behaviors has yet to be thoroughly examined in Japanese. This study aims to investigate the sex-specific independent and combined associations of CRF and BMI with MetS in middle-aged Japanese adults. Methods: 421 participants were included in this cross-sectional study. CRF was estimated using a submaximal cycle ergometer. CRF and BMI were respectively divided into three categories according to tertile distribution. MetS was diagnosed based on five risk factors: waist circumference, triglycerides, high-density lipoprotein cholesterol, blood pressure, and fasting glucose. Multivariable logistic regression models were used to estimate independent and combined association of CRF and BMI with MetS. Results: Results showed that 154 (57.5%) and 70 (45.8%) of men and women had MetS, respectively. Compared to men with lower CRF or higher BMI, men with middle and higher CRF or middle and lower BMI were less likely to have MetS. Compared with ‘unfit and higher BMI’ group, ‘unfit and lower BMI’, ‘fit and higher BMI’, and ‘fit and lower BMI’ groups in men showed statistically significant decreased prevalences of MetS. However, no significant associations were found in women. Conclusions: This study found significant independent and combined associations of CRF and BMI with MetS only in men, but not in women. However, prospective studies are warranted to confirm sex-specific associations of CRF and BMI with MetS.

Older adults hope to promote good health and extend their longevity, which will contribute to a better-aging society. The 32nd Annual Meeting of the Japanese Society for Health Education and Promotion held a symposium titled “Sustainability of Community-based Practical Research toward Extending Healthy Life Expectancy.” The aim of this symposium was to introduce several studies conducted in community-based practical settings to examine efforts for promoting health and extending longevity among older adults. After a brief introduction by the chairperson, three speakers (Dr. Uemura, Dr. Saito, and Dr. Harada) presented their own researches. Dr. Uemura proposed that health education through active learning (e.g., in-class group work, out-of-class homework and practice) could promote health behavior change and prevent frailty among older adults. Dr. Saito presented a multi-strategic community-wide intervention (e.g., distributing information, providing educational lectures and classes, supporting exercise communities) implemented in collaborations with a local municipal office, university, and local healthcare foundation that could elevate physical activity levels among adults of all ages, including older adults, in a community. Dr. Harada showed that a university-led event-based community program could increase neighborhood social networks; further, an increase in social networks could have a desirable influence on mental well-being among older adults. As the designated speaker, Dr. Oguma referred to the importance of a systems approach for the sustainability of community-based practical research.

Background: While physical activity (PA) can reduce physical frailty, the specific intensity and duration of PA required to prevent frailty are yet to be defined. Objectives: This study aimed to investigate the relationship between objectively measured PA or sedentary behavior (SB) and physical frailty and to explore the theoretical effect of replacing SB with different intensities of PA on the risk of frailty. Design: Cross-sectional study. Setting: Community-based assessments. Participants: Independently living adults aged 85–89 years participating in the Kawasaki Aging and Wellbeing Project. Measurements: PA was measured using a triaxial accelerometer for a minimum of 10 h per day over a minimum of 3 days. Physical frailty was measured using the revised Japanese version of the Cardiovascular Health Study criteria. Physical frailty was classified as non-frail, pre-frail, and frail. The relationship between PA and frailty was assessed using analysis of covariance. The effect of replacing SB with light-intensity PA (LPA) or moderate-to-vigorous-intensity PA (MVPA) on the risk of frailty was estimated using multinomial logistic regression and an isotemporal substitution model. Results: The analysis included 1004 participants (503 men and 501 women) of whom 242 were classified as frail. The mean step count, MVPA, and LPA were lower, and SB was higher in the frail group than in the non-frail group. SB replacement with MVPA for 10 min/day was associated with a significantly lower odds of frailty (odds ratio [95% confidence interval]: pre-frail men, 0.86 [0.77, 0.96]; frail men, 0.70 [0.60, 0.83]; pre-frail women, 0.77 [0.66, 0.90], frail women, 0.59 [0.47, 0.75]). SB replacement with LPA was not significantly associated with frailty odds in men or women. Conclusions: Replacing 10 min of SB with MVPA was associated with lower risk of frailty in adults aged 85–89 years. These findings require confirmation in longitudinal and intervention studies.

The global outbreak of novel coronavirus infection in the winter of 2020 led to city lockdowns and curfews in many parts of the world, forcing university athletes to suspend training. De-training negatively affects athletic performance. In school sports, temporary closures due to infectious diseases often occur yearly. Therefore, this study aimed to clarify the differences in the changes in various physical fitness factors between two different residential environments during the suspension of team activities. The observation period was 7 months, from March to September 2020. The baseline period was defined as the period before the voluntary suspension of team activities (March), the de-training period was the timeframe of suspension of team activities (April-May), and the follow-up period was defined as the period after the resumption of team practice (June-September). The study participants included 17 dormitory students and 14 home-schooled students in a university rugby team. The dormitories were equipped with training equipment and space for minimal training. The team staff provided a training program for both dormitory and non-dormitory students, which could be followed at home during periods when team practices were suspended. This study showed sig-nificant differences between dormitory and home-schooled students in the maximum lifting weight measurement of narrow chinning at baseline and after de-training. Other physical fitness factors did not differ significantly between groups or measurement periods. Although this study sample size was small and sufficient power could not be obtained, home weight training could maintain a certain level of maximum muscle strength as in the present study, suggesting that preparation for back exercises that can be performed at home is essential for the back muscles.

Background: Sarcopenia and frailty often worsen in older adults because of declines in activities of daily living and social connections that are associated with chronic diseases and traumatic injuries such as falls and fractures. Exercise intervention for sarcopenia can take >3 months to improve muscle mass, muscle strength, and walking speed. Thus, a specialized intervention system for shorter periods of time is needed. In this study, we aimed to evaluate the short-term efficacy of an exercise program using the wearable cyborg Hybrid Assistive Limb (HAL) lumbar type in physical function in mobility-limited older adults who do not require transition to long-term care. Methods: This randomized, single-blind, parallel-group study involved 79 community-dwelling older adults with physical frailty or locomotive syndrome assigned to an intervention group (n = 40) with the HAL lumbar type exercise program or a control group (n = 39) without the exercise program. The intervention group underwent trunk training (including trunk and hip flexion, standing and sitting from a single sitting position, and squats) and gait training (treadmill and parallel bars) twice a week for 5 weeks while wearing the HAL lumbar type. The 10-m usual and maximum walking speeds, Timed Up and Go test results, 5-times chair-standing test results, 5-question Geriatric Locomotive Function Scale (GLFS-5) scores, body-fat percentage, and muscle mass were measured before and after the intervention and analyzed using the intention-to-treat method. Results: The intervention (23 % male; mean age, 74.7 ± 4.7 years) and control (21 % male; mean age, 75.1 ± 4.1 years) groups did not differ significantly in baseline characteristics. Seventy-seven participants completed the program; two withdrew for personal reasons. The mean difference (standard error) between the groups for the primary outcome (usual walking speed) was 0.35 (0.04) m/s; the time-by-group interaction was significant (p < 0.001). Secondary outcomes (maximum walking speed, Timed Up and Go test results, 5-times chair-standing test results, and GLFS-5 scores) significantly improved in the intervention group. Body composition was unchanged in both groups. Conclusions: A 5-week exercise program using the HAL lumbar type is a promising option for community-dwelling older adults with limited mobility who do not require nursing care, resulting in clinically meaningful improvements in most physical functions within a short period.

Abstract

Although cross-sectoral cooperation is important at all levels, in practice it often remains at a declarative level. Different sectoral policies and the resulting measures to promote HEPA are usually disconnected, uncoordinated and without the necessary synergies. This pertains especially to local environments with less financial and expert support, such as small rural communities, where people have few HEPA options that are suitable and attractive for vulnerable groups: children and adolescents, elderly and people with disabilities.

“Development of indicators for the assessment of the provision of settlements with green spaces for outdoor physical activity” is a research project co-funded by the Slovenian Research and Innovation Agency, the Ministry of Health and the Ministry of Natural Resources and Spatial Planning and implemented at the Urban Planning Institute of the Republic of Slovenia. The aim of the project is to define indicator(s) for the provision of green spaces for PA and active lifestyles in settlements, which could be used at local level to assess, improve, and monitor the situation. We took a medium-sized city and a small rural community as pilot projects, the latter often being a disadvantaged environment in terms of HEPA in spatial planning compared to larger cities. On the pilots, our objectives have been to establish cooperation at the local level between at least three different sectors and to test methodology and indicators developed in the project to assess the provision of green spaces to promote PA in selected environments, thus enabling more equitable and inclusive spatial conditions for HEPA at the local level.

The presentation will present the approach, results and overall experiences with the work implemented in the pilot project of a rural community. It will highlight the benefits of cross-sectoral cooperation for more effective local level HEPA policies to ensure the inclusive and equitable access to green spaces in settlements.

Objectives Numerous reports have described injuries and illnesses in competitive athletes, but studies on leisure-time physical activity and associated adverse events in the general population have not been adequately reviewed. This study aimed to summarise the previous findings on this topic. Design Scoping review. Data sources PubMed and Ichushi-Web for articles in English and Japanese, respectively (13 April 2023). Eligibility criteria for selecting studies Articles on adverse events related to sports performed by € individuals and groups active in the community' were included, whereas those on elite athletes, exercise therapy and rehabilitation, and school sports were excluded. Terms related to physical activity, exercise, sports and adverse events were used for the search strategies. Results The literature search yielded 67 eligible articles. Most articles were from the USA, Japan and Australia. Running, scuba diving, rugby and soccer were the most commonly reported sports. Adults were the most common age category in the samples. The most commonly reported adverse events were injuries; only 10 articles reported diseases. 13 longitudinal studies reported the frequency of adverse events based on the number of events/participants×exposure. Conclusion Adverse events such as sports trauma, disability and certain diseases occur sometimes during sporting activities by residents; however, the articles identified in this review showed biases related to the countries and regions where they were published and the sports disciplines and types of adverse events reported, and articles reporting the frequency of adverse events were also limited. This highlights the need for more high-quality observational studies on diverse populations in the future.

Objective: To present a logic model for increasing daily steps in the population and to categorize interventions using a ladder of interventions. Additionally, an example action plan is provided.Methods: Relevant policies and studies were reviewed, and 23 experts were interviewed. The logic model, based on the SLOTH model (Sleep, Leisure, Occupation, Transportation, Household), categorized daily life domains and considered steps during work, transportation, and at home & in the community as intermediate outcomes. Individual interventions were categorized using a ladder of interventions. An example action plan introduced multi-strategic community-wide interventions with evidence of success in promoting physical activity at the community level.Results: The logic model outlined individual interventions categorized by implementing entities (government, workplaces, health insurance associations, schools, related organizations). By envisioning domains of walking, specific measures emerged to increase step counts. The proposed individual interventions included not only information provision and health education but also interventions corresponding to levels 1-6 of the ladder of interventions. Multi-strategic community-wide intervention is an intervention that works on multiple levels of factors from individual to environment in a multifaceted manner, indicating the need for collaboration with various organizations and residents on a long-term basis from the perspective of the target population.Conclusion: Efforts should be directed not only within the health and welfare sector but also across various sectors such as education, sports, urban planning, and urban transportation. Strategies tailored to specific domains of daily life and from the perspective of residents should be considered, and a long-term, systematic approach is needed.
