BACKGROUND: As the Japanese population continues to age, functional decline with aging will inevitably become more pronounced. Vision loss and decline in lifestyle and motor functions are the main causes of functional decline. To date, a few studies have examined the relationship between visual and overall physical function. Therefore, this study aimed to quantitatively investigate the relationship between loss of visual acuity and the decline of physical functionality. METHODS: This cross-sectional study was based on the data of 86 community-dwelling older adults (average age ± standard deviation, 75.7 ± 5.5 years; 34 men) who participated in the October 2020–May 2022 baseline survey. Visual function was assessed based on the measurement of binocular near functional visual acuity (NFVA) using the Smart Vision Check application. Physical function tests were performed by measuring grip strength, 30-second chair stand (CS-30), Timed Up and Go (TUG), with eyes open, one-leg standing balance (OLSB), and two-step test. Multivariate regression analysis was performed to examine the association between NFVA and physical function, and partial regression coefficient (β) and 95% confidence interval (95%CI) were calculated. RESULTS: After adjusting for all covariates, NFVA was significantly associated with grip strength (β: 3.54, 95%CI: 0.39, 6.70). Meanwhile, no association was noted between NFVA and CS-30 (β: -0.35, 95%CI: -2.68, 1.97), TUG (β: -0.23, 95%CI: -0.65, 0.19), OLSB (β: 6.13, 95%CI: -5.09, 17.35), and two-step test (β: 0.01, 95%CI: -0.05, 0.08). CONCLUSIONS: The study showed an association between quantitatively assessed visual and physical functions in community-dwelling older adults living in Japan. Thus, the findings indicate that maintaining and enhancing grip strength and visual function in older adults may be an important factor in leading a healthy and fulfilling life.

BACKGROUND: Mobile apps and peer support are known to effectively promote physical activity in older adults, which, in turn, improves physical function. Previously, we investigated the feasibility and impact of using digital peer-supported apps (DPSAs) to increase physical activity among older adults over a 3-month period. However, the long-term feasibility and impact on sustainable behavior change remain unknown. OBJECTIVE: This study aims to evaluate the 12-month feasibility of the DPSA and to obtain preliminary estimates of its effects on physical activity and physical function among older Japanese adults. METHODS: This nonrandomized controlled trial recruited older adults aged 65 years or older from 2 physical activity programs. Participants chose either the intervention (app program + exercise instruction) group or the control (exercise instruction only) group. Only those participants who had completed the 3-month intervention and wished to continue in the 12-month follow-up intervention study were included. DPSA feasibility was assessed using retention and adherence rates. Physical activity was assessed using accelerometers, capturing daily step count, light-intensity activity, moderate to vigorous intensity activity, and sedentary behavior. Physical function was evaluated using grip strength and the 30-second chair stand test (CS-30). Accelerometer measurements were collected every 3 months over 12 months (5 time points, including baseline), whereas physical function was measured at baseline, 3 months, and 12 months. RESULTS: The follow-up study included 44 of 66 participants from the 3-month intervention study, with 26 participants in the intervention group and 18 participants in the control group. The 12-month retention rate for participants in the DPSA intervention group was 73% (19/26), whereas the retention rate among all 41 participants, including those who chose not to participate in the follow-up study, was 46% (19/41). The adherence rate was 85.9%. The average number of steps per day (95% CI) in the intervention group changed before and after DPSA use (P=.048). We observed an increase of 1736 (β=1736, 95% CI 232-3241) steps per day compared with baseline. No significant change was observed in the control group. There were significant within-group differences in CS-30 scores for both intervention (P<.001) and control (P=.03) groups over the 12-month period. Specifically, there was a significant change in CS-30 scores (95% CI) between the baseline and 12-month assessments for the intervention (β=6.5, 95% CI 3.8-9.1; P<.001) and control (β=3.8, 95% CI 0.6-7.1; P=.02) groups. CONCLUSIONS: Participants with long-term DPSA use observed increases in average daily steps and CS-30 scores before and after DPSA use, although only a limited number of older adults had long-term access to the DPSA. Identifying ways to expand long-term DPSA use among older adults is necessary. Additionally, randomized controlled trials should be conducted to determine the long-term effects of DPSAs on physical activity and function in older adults.

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.

BACKGROUND: The use of mobile apps has promoted physical activity levels. Recently, with an increasing number of older adults accessing the internet, app-based interventions may be feasible in older populations. Peer support-based interventions have become a common method for promoting health-related behavior change. To our knowledge, the feasibility of using digital peer support apps (DPSAs) to increase physical activity among older adults and its impact on physical activity and physical function have not been investigated. OBJECTIVE: This study aims to assess the feasibility of using DPSAs in older adults and to assess changes in physical activity and physical function in DPSA users. METHODS: We conducted a nonrandomized controlled trial of older adults aged ≥65 years. We recruited participants for 2 distinct 12-week programs designed to increase physical activity. Participants could choose between an intervention group (app program and exercise instruction) or a control group (exercise instruction only). DPSA creates a group chat for up to 5 people with a common goal, and participants anonymously post to each other in the group. Once a day, participants posted a set of their step counts, photos, and comments on a group chat box. The intervention group used the DPSA after receiving 2 face-to-face lectures on its use. The participants were characterized using questionnaires, accelerometers, and physical function assessments. The feasibility of the DPSA was assessed using retention and adherence rates. Physical activity was assessed using accelerometers to measure the daily step count, light intensity physical activity, moderate to vigorous intensity physical activity (MVPA), and sedentary behavior. Physical function was assessed using grip strength and the 30-second chair-stand test. RESULTS: The participants in the intervention group were more frequent users of apps, were more familiar with information and communication technology, and had a higher baseline physical activity level. The retention and adherence rates for the DPSA intervention were 88% (36/41) and 87.7%, respectively, indicating good feasibility. Participants in the intervention group increased their step count by at least 1000 steps and their MVPA by at least 10 minutes using the DPSA. There was a significant difference in the interaction between groups and intervention time points in the daily step count and MVPA (step count, P=.04; duration of MVPA, P=.02). The DPSA increased physical activity, especially in older adults with low baseline physical activity levels. CONCLUSIONS: The feasibility of DPSA was found to be good, with the intervention group showing increases in daily steps and MVPA. The effects of DPSA on step count, physical activity, and physical function in older adults with low baseline physical activity should be investigated using randomized controlled trials.

<p> [Purpose] This study aimed to determine the effects of a mobile health application, and exercise instructions by a physical therapist on exercise frequency, duration, and intensity for middle-aged and older adults. [Participants and Methods] The study included males and females in their 50s to 70s, who provided consent to participate. Thirty-six people who wished to participate in the online group were divided into groups of five or six each, with a physical therapist as group leader. The frequency, intensity, duration of exercise, and group activities were surveyed using questionnaires: before coronavirus disease (COVID-19) (before March 2020, when the novel coronavirus began to spread in Japan), during COVID-19 (after April 2020), after digital versatile disc (DVD) distribution, and after online group initiation (3 weeks after DVD distribution for the control group). [Results] The online group received significantly more frequent instructions by a physiotherapist than the control group. The control group did not show significant changes over time, whereas the online group exercised significantly, more frequently after the intervention. [Conclusion] The online mode and physical therapist intervention resulted in a significant increase in exercise frequency. Exercise advice from professionals and peer presence to continue exercising together were beneficial.</p>
