the AI-PEF group, receiving a machine learning-powered personalized exercise program.

Participants will follow a 24-week walking program with at least three 30-minute sessions per week, with exercise intensity progressively adjusted based on heart rate and effort indices. Garmin fitness trackers will monitor exercise adherence and intensity. Remote guidance will be provided through five AI-generated digital health messages per week via LINE, delivered on Monday, Tuesday, Thursday, Friday, and Saturday, and tailored to participants' exercise performance and individualized goals established during the remote exercise intervention and consultation. The messages will include exercise performance feedback, goal setting and reinforcement, exercise and device-use reminders, health education, and encouragement and support. The digital component will allow participants to share their progress and seek guidance during scheduled in-person consultations. AI-driven digital feedback provides a convenient and accessible approach to supporting participants in engaging in exercise.

In this study, the Biolight MediTECH® near-infrared brain blood flow imaging sensor (hemoencephalography; HEG) was used to measure blood flow in the prefrontal cortex. The Biolight near-infrared spectroscopy device is an HEG sensor designed by MediTECH®, based on NIR technology to observe the optical properties of cells and tissues at the reflection level. This enables monitoring of changes in oxyhemoglobin and deoxyhemoglobin concentrations. By measuring light absorption at different wavelengths, the system can continuously track changes during tissue oxidation processes, thereby measuring cerebral blood flow conditions. The percentage of the NIR brain blood flow ranged 0- 100%, the higher percentage means the higher prefrontal brain blood flow.

The percentage of the NIR brain blood flow ranged 0- 100%, the higher percentage means the higher prefrontal brain blood flow.

Preliminary findings from this study applied the cardiac metabolic performance benchmark (CMPB3) to compare the effectiveness of increasing cerebral blood circulation at different intensities (CMPB3 ≤ 35, 40, 45, 50). Results indicated that CMPB3 levels above 40 effectively increased cerebral blood circulation, with improvements observed not only during exercise but also during the post-exercise rest period, where cerebral blood flow remained higher than the baseline level. The lower intensity means the lower exercise intensity and the higher ability to perform aerobic walking exercise. The benchmark will be calculated by the Heart rate measured by Garmin fitness bracelet.

Garmin Vivosmart 5. This wearable device will track heart rate, exercise frequency, exercise duration, exercise intensity, step count, and sleep data. Data will be integrated with the Garmin Connect app for real-time monitoring and feedback. A preliminary study conducted by our research team in 2020 showed a high correlation (r = 0.91) between heart rate measurements obtained from the Garmin Vivosmart and the Zephyr BioHarness, supporting its use for home-based heart rate monitoring. Participants will wear the device at home to facilitate real-time tracking of exercise intensity and physiological responses during the intervention. Advanced sleep tracking in compatible Garmin devices incorporates multiple factors to provide information on sleep patterns. In addition to basic information, such as sleep onset and wake-up time, researchers will be able to obtain data on periods of wakefulness and time spent in key sleep stages, including light, deep, and rapid eye movement (REM) sleep.
