Brisk Walking and Baduanjin Improve Inhibitory Function in Older Adults With Cognitive Impairment
This study aims to investigate the acute effects of single-session different forms of aerobic exercise (brisk walking and Baduanjin) on inhibitory function and resting-state EEG power in older adults with cognitive impairment, providing scientific evidence for developing exercise intervention programs for this population.
Specifically, this study seeks to answer the following core questions:
1. Can a single session of brisk walking and a single session of Baduanjin exercise improve reaction time and accuracy on the Stroop color-word task in older adults with cognitive impairment?
2. Are there differential effects on inhibitory function between the two exercise modalities?
3. Does a single exercise session induce immediate changes in resting-state EEG power spectrum across multiple frequency bands (δ, θ, α, β)?
4. Are changes in resting-state EEG power associated with improvements in inhibitory function?
Forty-five older adults with cognitive impairment will be randomly assigned to three groups (n=15 each): brisk walking group, Baduanjin group, and control group (quiet seated rest). Participants in the brisk walking and Baduanjin groups will each perform a single 30-minute moderate-intensity exercise session. All participants will complete the Stroop color-word task (assessing reaction time and accuracy under both congruent and incongruent conditions) and undergo a 5-minute eyes-closed resting-state EEG recording before and immediately after the intervention.
