Abstract

Posture and cognitive abilities may interact, with higher cognitive workloads potentially triggering automatic postural control, leading to a more stable platform. However, the neural and physiological mechanisms behind this relationship remain unexplored. To address this, our study investigates cortical activity during single and dual tasks before and after a brief physical activity session. We will recruit twenty healthy participants aged 18 to 65 years and use functional near-infrared spectroscopy (fNIRS) to measure brain activity. Additionally, physiological signals, including heart rate, respiratory rate, and blood pressure, will be recorded with the Biopac system during tasks. This research aims to shed light on the neural and physiological factors affecting posture-cognitive dual-task performance following acute physical activity, potentially guiding future interventions for optimizing performance across different age groups.
