Abstract:
Links between cognition and balance are well established in older adults and athletes, but evidence in healthy young adults is limited. This cross-sectional study examined the relationship between cognitive domains (processing speed, working memory, and inhibition) and static and dynamic balance in 62 adults aged 18-45 years. Participants completed cognitive tests (Deary-Liewald, Stroop, N-back) and balance assessments (Sway Medical App, Y Balance Test). Correlation and hierarchical multiple regression analyses revealed no significant association between cognition and balance, while a higher BMI was associated with poorer dynamic balance. These findings suggest that in early adulthood, postural stability during single-task assessments may rely on automated motor control rather than cognitive processes. This could support the idea of early adulthood as a period of motor autonomy. Future research should test complex or dual-task conditions to identify potential cognitive involvement and inform early interventions for lifelong motor-cognitive health.
