Age-related differences in dual task performance: A cross-sectional study on women

Area of Science:

• Gerontology
• Kinesiology
• Cognitive Neuroscience

Background:

• Everyday activities often require simultaneous performance of motor and attention-demanding tasks.
• Understanding age-related differences in dual-tasking is crucial for maintaining mobility and independence.

Purpose of the Study:

• To examine age-related changes in mobility performance under dual-task conditions.
• To evaluate the dual-task cost (DTC) on motor performance across different age groups of women.

Main Methods:

• Cross-sectional study involving 90 women (young, middle-aged, older).
• Participants performed the Timed Up & Go Test under single-task, cognitive dual-task (counting backwards), and manual dual-task (carrying water) conditions.
• Repeated measures ANOVA and ANCOVA were used to analyze mobility performance and DTC.

Main Results:

• A significant interaction between age and task type was observed, indicating age-related differences in dual-tasking.
• Older women exhibited worse mobility performance under dual-task conditions compared to younger and middle-aged women.
• Dual-task cost was significantly higher for the cognitive task in older women, but not for the manual task.

Conclusions:

• Dual-task conditions present unique challenges that vary across the lifespan.
• Cognitive dual-tasking, in particular, is more demanding for older women, potentially impacting their mobility.
