Tai Chi Chuan (TCC) is a promising intervention against age-related decline. Though previous studies have shown benefits in motoric and cognitive domains, it is unclear how these effects are functionally related. Therefore, a randomized controlled trial was conducted in an aging population (53-85). Two measures of motor functioning - motor speed and functional balance - and three cognitive control measures - shifting, updating and inhibition - were included. The TCC condition consisted of an online 10 week 20 lessons video program of increasing level and control condition of educational videos of similar length and frequency. All analyses were done with Bayesian statistics. Counter to expectation no differences were found in cognition between TCC and control pre-to-posttest. However, there was extreme evidence for TCC benefits on functional balance and moderate evidence for increased motoric speed. After weighing the evidence and limitations of the intervention we conclude that TCC does not enhance cognitive control.
