Does Mind-Body Exercise Help Attention in Older Adults?
Baduanjin mind-body exercise improved selective attention in older adults with mild cognitive impairment, but this improvement was not clearly linked to changes in brain network connections.

60 older adults
A total of 69 participants underwent baseline attention tests and MRI scans, of which 60 completed the post-intervention attention tests and MRI scans (20 individuals in each group).
three groups
One-way analysis of variance (ANOVA) or a non-parametric test was applied to compare differences across the three groups.
What they did
The researchers assigned 60 older adults with mild cognitive impairment to three groups for a 24-week study. One group practiced Baduanjin, a traditional Chinese mind-body exercise, for 60 minutes three times a week; another group did brisk walking with the same schedule; and another group served as a usual-activity control. Before and after the training, participants completed attention tests and underwent resting-state functional MRI scans.
What they found
After 24 weeks, the Baduanjin group showed a significant increase in selective attention accuracy compared to the control group. Brain scans revealed decreased functional connectivity in several regions of the dorsal attention network for the Baduanjin group compared to the other groups. However, statistical analysis did not find a direct relationship between these brain connectivity changes and the improvements in attention.
The limits
What it doesn't show
The study cannot prove that changes in the dorsal attention network caused the behavioral attention improvements, as there was no significant correlation between the two. Because the sample size was relatively small with 20 participants per group, the statistical power to detect subtle brain-behavior links was limited. The study also cannot rule out that other factors, like social interaction or differences in exercise intensity, influenced the results since Baduanjin's intensity is difficult to measure.
Key terms
- Baduanjin
- A traditional Chinese mind-body exercise that combines physical postures, breathing techniques, and mental focus.
- Mild Cognitive Impairment (MCI)
- A transitional state between normal age-related cognitive decline and dementia, characterized by minor memory or attentional issues.
- Dorsal Attention Network (DAN)
- A network of brain regions involved in the voluntary, top-down control of attention.
- Functional Magnetic Resonance Imaging (fMRI)
- An imaging technique that measures brain activity by detecting changes associated with blood flow.
- Functional Connectivity
- A measure of how much the activity of different brain regions is synchronized or correlated over time.
- Stroop Task
- A psychological test used to assess selective attention and processing speed by measuring response times to conflicting stimuli.

What was the primary purpose of this study on older adults with Mild Cognitive Impairment (MCI)?
Common questions
Did brisk walking show any benefits in this study?
Brisk walking did not significantly improve performance on the attention tasks compared to the control group, though it did show different patterns of brain connectivity changes compared to Baduanjin.
What makes Baduanjin different from brisk walking?
While brisk walking is a standard aerobic exercise, Baduanjin is a mind-body exercise that requires active coordination of posture, breathing, and mental concentration.
Why did brain connectivity decrease in the Baduanjin group?
The authors suggest that this decreased connectivity might represent a beneficial adjustment, helping to maintain distinct boundaries between different brain networks, though more research is needed to verify this.
How long did the exercise programs last?
Both the Baduanjin and brisk walking programs lasted for 24 weeks, with participants exercising three times a week for 60 minutes per session.
