How an Age Simulation Suit affects Motor and Cognitive Performance and Self-perception in Younger Adults

Area of Science:

• Gerontology
• Human Performance
• Biomechanical Engineering

Background:

• Aging is associated with declines in motor and cognitive functions.
• Understanding these changes is crucial for developing interventions and support systems.
• The Age Simulation Suit (GERT) provides a novel tool to study these effects.

Purpose of the Study:

• To evaluate the impact of the GERT suit on gross motor, fine motor, and cognitive performance in young adults.
• To quantify the simulated age-related performance decrements.

Main Methods:

• A within-subjects design was employed with 20 healthy young adults.
• Participants completed motor (Functional Fitness test, Purdue Pegboard test) and cognitive (Digit Symbol Substitution test) assessments with and without the GERT suit.
• Questionnaires assessed perceived physical state and mood.

Main Results:

• The GERT suit significantly reduced performance across all tested dimensions (gross motor, fine motor, cognitive) with large effect sizes.
• Performance decrements simulated those of individuals aged 50-85 years.
• Mood and perceived physical state also declined when wearing the suit.

Conclusions:

• The GERT suit effectively simulates age-related sensory and motor losses in a controlled experimental setting.
• This paradigm holds potential for future research in cognitive-motor dual-tasking and motor learning in aging.
• The suit offers a valuable tool for gerontological research and understanding the physical experience of aging.
