背景抑制控制是执行功能的子能力，在整个认知过程中发挥着重要作用。然而，衰老过程中抑制控制的下降会严重损害老年人的生活质量。研究延缓抑制控制衰退的方法已成为当前研究的焦点。太极拳（TCC）是延缓老年人认知能力下降的有效方法之一。然而，TCC 对抑制控制的具体作用以及 TCC 改善老年人认知的机制尚未得到全面研究。目的 该研究利用功能性近红外光谱 (fNIRS) 技术和反应时间 (RTs) 探讨 TCC 干预对老年人抑制控制影响的可能神经机制。方法共有26名未接受过TCC培训的健康老年人完成了所有研究程序。受试者被随机分为 TCC 组或对照组。 TCC 组的受试者由经过认证的讲师教授 TCC，并接受为期 8 周的培训。对照组继续进行一般日常活动。对每位参与者进行侧翼任务，以评估干预前后的抑制控制。当参与者执行侧卫任务时，收集 fNIRS 数据。结果 干预后，仅在 TCC 干预组中发现不一致侧翼的显着差异。在 TCC 组中观察到不一致侧翼的 RT 比对照组更快 (p < 0.05)。对 fNIRS 数据的分析显示，TCC 运动干预后，在不一致的侧翼期间，前额皮质中的氧 -Hb 增加。结论 TCC干预显着改善了老年人的抑制控制能力，表明TCC是一种有效、适合改善老年人执行功能和神经健康的运动。临床试验注册中国临床试验注册中心，ChiCTR1900028457。
Background Inhibitory control is a sub-ability of executive function and plays an important role in the entire cognitive process. However, declines in inhibitory control during aging significantly impair the quality of life of elderly people. Investigating methods to delay the decline of inhibitory control has become a focal point in current research. Tai Chi Chuan (TCC) is one effective method used to delay cognitive declines in older adults. However, the specific effects of TCC on inhibitory control and the mechanisms through which TCC may improve cognition in older adults have not been comprehensively investigated. Objective The study explores possible neurological mechanisms related to the effects of TCC interventions on inhibitory control in older people using a functional near-infrared spectroscopy (fNIRS) technique and reaction times (RTs). Methods A total of 26 healthy, elderly people who had not received TCC training completed all study procedures. The subjects were randomized to either the TCC group or the control group. Subjects in the TCC group were taught TCC by a certified instructor and trained for 8 weeks. The control group continued to perform general daily activities. The Flanker task was administered to every participant to evaluate inhibitory control pre- and post-intervention. While participants were performing the Flanker task, fNIRS data were collected. Results Post-intervention, significant differences for incongruent flankers were found only for the TCC intervention group. Faster RTs were observed for the incongruent flankers in the TCC group than in the control group (p < 0.05). Analysis of the fNIRS data revealed an increase in oxy-Hb in the prefrontal cortex during the incongruent flankers after the TCC exercise intervention. Conclusion The TCC intervention significantly improved inhibitory control in older adults, suggesting that TCC is an effective, suitable exercise for improving executive function and neurological health in elderly people.
