背景：太极拳是延缓老年人认知功能减退的有效方法之一。然而，长期练习TCC与老年人大脑中关键的工作记忆更新功能之间的关系尚未得到全面的研究。目的：本横断面研究探讨了实验室环境下的行为表现与长期使用TCC对老年人N-back任务的反应时(RTS)更新功能的关系。方法：26名健康老年人参加本次实验。根据练习TCC的时间长短，TCC组中有13名TCC锻炼经验超过5年的受试者，另有13名未系统进行过心身锻炼的老年受试者被分配为新手组。对每个参与者执行N-back任务以评估更新功能。结果：TCC组的反应时反应时较新手组快(p<；0.05)，在1-back任务上，TCC组的反应时反应时较新手组快。在2-back任务中，新手组比TCC组表现出更快的反应时反应时。结论：与TCC新手相比，TCC专家具有更强的更新功能。长期的TCC似乎与老年人的更新功能呈正相关，使其成为维持老年人认知功能的有效运动。
Background: Tai Chi Chuan (TCC) is one effective method used to delay cognitive decline in older adults. However, the relationship between the long-term practice of TCC and the crucial working memory updating function of the brain in the elderly has not been comprehensively researched.Objective: This cross-sectional study explores how behavioral performance in a laboratory setting is related to long term practice of TCC on the updating function in older people using reaction times (RTs) of N-back tasks. Methods: 26 healthy elderly people participated in this experiment. According to the length of time TCC was practiced, 13 subjects in the TCC group had more than 5 years’ experience of TCC exercise, and 13 elderly subjects who had not been systematically exposed to mind-body exercise were assigned to the novice group. The N-back task was administered to every participant to evaluate the updating function. Results: The TCC group had faster RTs compared to the novice group (p<0.05); For the 1-back task, the TCC group showed faster RTs than the novice group. For the 2-back task, the novice group exhibited faster RTs than the TCC group. Conclusions: TCC experts exhibit greater updating function as compared to TCC novices. Long-term TCC appears to be positive associated with the updating function of older adults, making it an effective exercise to maintain cognitive function in the elderly.
