Physical activity is very important for staying healthy and improving how well our brain works. Walking is a simple and easy way to exercise that can help people of all ages feel better physically and mentally. It's affordable, easy to do, and doesn't require special equipment. Walking can improve memory, thinking speed, and problem-solving skills, which are important for everyday life.

This study looks at whether doing shorter walks more often (like three 10-minute walks a day) is as good for the brain as doing one longer walk (one 30-minute walk a day). This is important because many people find it hard to fit long exercise sessions into their day due to busy schedules, health issues, or personal preferences.

By understanding which way of walking helps the brain the most, doctors and patients can choose exercise plans that are easier to stick to and still improve thinking skills. This study will compare these two walking routines over 6 weeks to see how they affect brain health.

This clinical trial investigates the cognitive effects of two different walking exercise protocols over a 6-week period. Participants will either complete three daily 10-minute walking sessions or a single continuous 30-minute walking session. The study aims to determine whether shorter, more frequent exercise sessions provide cognitive benefits comparable to a longer, single session. Outcomes will focus on improvements in memory, processing speed, and executive function. Findings will inform recommendations for accessible and flexible exercise programs to enhance cognitive health.
