This study examines whether a single session of exergaming-based seated Tai Chi can acutely improve working memory, executive function, and prefrontal cortical efficiency in younger and older adults, compared with seated stretching. Using a within-subject crossover design, 40 participants aged 18-30 years and 60-75 years will complete both conditions in counterbalanced order on separate days. Cognitive performance will be assessed with Flanker and n-back tasks, while prefrontal activity will be recorded with fNIRS over the dorsolateral, ventrolateral, and frontopolar prefrontal cortex. Neural efficiency will be estimated by integrating task performance with task-evoked oxygenated hemoglobin responses. The Tai Chi intervention is a 40-minute seated, exergame-guided 12-form routine preceded and followed by brief warm-up and cool-down periods. The control condition is a time-matched seated stretching programme without Tai Chi-specific movements or game feedback. Both conditions will be delivered at light-to-moderate intensity and supervised for safety and adherence. The study tests whether acute exergaming-based seated Tai Chi produces greater post-intervention improvements in cognitive performance and more efficient prefrontal activation than stretching, and whether these effects differ by age group. Findings may clarify how a feasible seated mind-body exergame influences acute cognitive and neural responses across the adult lifespan.
