Influence of Overground Walking on Biomarkers, Cognitive Function, and Quality of Life in Elderly With Mild Cognitive Impairment

This research employs a quasi-experimental research design using a Pretest-Posttest Design approach. The Pretest-Posttest method is executed by assessing before and after the intervention within the same group.

All research subjects receive the same treatment, which involves participating in an overground walking program on a flat surface. The selected research subjects are provided with an explanation of the research's objectives and benefits and the exercise and examination procedures, then sign the informed consent.

Research subjects are instructed to walk on a flat surface for a distance of 15 meters, with a duration of 20 minutes, increasing by 5 minutes each week until the target heart rate is achieved during the exercise. After an 8-week post-intervention period, research subjects will undergo a follow-up examination.
