Rapid population aging necessitates strategies to prevent frailty and maintain quality of life in older adults. This study aimed to verify the effects of adapted sports programs created by community-dwelling older residents. However, the COVID-19 pandemic forced the cancellation of face-to-face interventions. Consequently, the objective shifted to exploring methods for social connection and health maintenance. This study investigated Social Networking Services (SNS) usage among older adults to prevent social isolation and proposed a new adapted sport model feasible under restricted conditions. The research employed a mixed-methods approach: qualitative analysis of SNS usage, longitudinal quantitative surveys, and home-based adapted sport development. First, a LINE app intervention with older women was conducted. Although eight participants joined, six remained active, sharing frailty prevention quizzes and exercise videos weekly. Engagement patterns were analyzed. Second, longitudinal surveys (2019–2024) assessed mobile phone usage and social networks. Social isolation was measured using the Lubben Social Network Scale (LSNS-6). The relationship between device usage types and social isolation scores was analyzed. Third, "Adapted Table Rally" was developed as an accessible sport. This activity uses household items, like dining tables, newspapers, and milk cartons, ensuring accessibility. Qualitative analysis identified three engagement types: (1) no active engagement, (2) passive information passing, and (3) active reactions and sharing. Quantitative surveys revealed smartphone ownership among older adults rose from 86.6% in 2019 to 95.0% in 2024. Similarly, SNS usage increased from 16.3% in 2021 to 35.6% in 2024. In 2023, participants using internet/mail plus calls showed significantly higher LSNS-6 scores vs. non-users (p=0.5). However, this significance diminished in 2021. Logistic regression indicated SNS users were significantly less likely to experience social isolation (OR=2.463). The study highlights the critical role of ICT and SNS in maintaining social connections for older adults during physical isolation. While the immediate impact of digital connectivity varied as restrictions lifted, high smartphone adoption suggests SNS is a viable tool for frailty prevention. Furthermore, "Adapted Table Rally" provides a practical, low-cost activity model. Integrating digital literacy support with accessible Adapted sports is an effective strategy for preventing frailty in the post-pandemic era.
