Brief summary

This study tested preliminary efficacy of a hybrid (web-based and center-based) PA intervention combining use of a smartwatch and mobile application. The 12-week hybrid PA intervention included 120 older Korean adults and was concurrently implemented in-person at the local senior center and at-home through a web-based modality. Overall, increases were evident in systolic/diastolic blood pressure, total cholesterol, and high-density-lipoprotein at posttest, with decreases seen for triglyceride levels. Participants showed improvements in muscular function and cardiopulmonary endurance.

Interventions

BEHAVIORALGolden Circle

The original Golden Circle project was deployed in response to the COVID-19 pandemic and the need to implement remote social services in South Korea. Golden Circle had the aim of building a case management model using a healthcare-oriented automation system based on wearable devices (smartwatches and mobile applications). Through innovative system expansions, the goals were to promote healthful CVH and physical function and cultivate self-care management skills in older Korean adults.
