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.
太极拳（TCC）是一种很有前途的对抗与年龄相关的衰退的干预措施。虽然之前的研究已经表明在运动和认知领域有好处，但这些影响如何在功能上相关尚不清楚。因此，在老龄化人群中进行了一项随机对照试验（53-85 岁）。包括两项运动功能测量指标——运动速度和功能性平衡，以及三项认知控制测量指标——转换、更新和抑制。TCC 条件包括一个在线的 10 周 20 节课的视频课程，内容逐渐增加，控制条件为类似长度和频率的教育视频。所有分析均采用贝叶斯统计进行。与预期相反，TCC 组和对照组在认知方面的前后测试没有差异。然而，有极端证据表明 TCC 对功能性平衡有益，有中度证据表明运动速度提高。在权衡了干预措施的证据和局限性后，我们得出结论，TCC 不能增强认知控制。
