The Effects of Intelligent Intervention Programs on Hospitalized Elderly People With Frailty.

The intervention involves a structured exercise program, with participants in the experimental group engaging in cycling exercises three times per week, each session lasting 30 minutes during hospitalization. After discharge, they will follow a walking program, increasing their daily step count by 1,000 steps above the average recorded during hospitalization, for a total of 12 weeks. Structured questionnaires and medical records will be used for data collection at four time points: the first week of enrollment (T0), hospital discharge (T1), the eighth week post-enrollment (T2), and the twelfth week post-enrollment (T3). Additionally, a tri-axial accelerometer-equipped smart wristband will be used to monitor and record participants' heart rate, respiration, blood pressure, daily step count, and sleep quality.
