Effects of Physical-Cognitive Dual Task Training on Executive Function and Gait Performance in Older Adults: A...

Area of Science:

• Gerontology
• Neuroscience
• Exercise Science

Background:

• Aging is associated with declines in physical and cognitive functions.
• Integrating cognitive challenges into physical training is a promising area of research.
• Executive functions, crucial for daily activities, are particularly vulnerable to age-related decline.

Purpose of the Study:

• To investigate the effects of a 12-week physical-cognitive dual-task (DT) training program on executive function and gait in older adults.
• To compare the outcomes of DT training with single-task (ST) physical training.

Main Methods:

• Thirty-six healthy older adults (mean age 72.30 ± 5.84 years) were divided into ST (n=16) and DT (n=20) training groups.
• Intervention involved 12 weeks of designed physical training.
• Executive function (inhibition, working memory) and gait (walking with/without hurdles) were assessed pre- and post-intervention under ST and DT conditions.

Main Results:

• Both groups showed improvements in gait performance.
• Inhibitory function declined after ST training but tended to increase after DT training.
• Changes in inhibition correlated with DT walking performance, with complexity influencing group differences.

Conclusions:

• Group exercise classes can enhance gait performance in older adults.
• Physical-cognitive DT training specifically mitigates age-related executive function decline.
• DT training shows potential for maintaining essential cognitive functions for daily living in aging populations.
