Preliminary Efficacy of a Technology-based Physical Activity Intervention for Older Korean Adults During the COVID-19 Pandemic

Study Overview
=================
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.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Hybrid PA intervention<br>The PA intervention implemented 1-hour sessions for 12 weeks focusing on improving (1) body muscle, (2) body flexibility, (3) muscle endurance, and (4) body balance. The 12-week hybrid PA intervention was concurrently deployed in-person at a senior center and at-home through a web-based modality. | Behavioral: Golden Circle<br>* 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.<br>|
