• Interventions: Behavioral: Golden Circle

• Registration Number: NCT05986058
• Lead Sponsor: University of Illinois at Urbana-Champaign

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.
