1,2,5]. For example, TC has played a significant role in the recovery of patients who suffered from stroke, Parkinson disease, traumatic brain injury, and multiple sclerosis [6,7]. Because of its beneficial effects on health promotion and improvement of human dysfunctions including neurological disorders, TC has been considered as one of the most promising exercise programs that people with neurological diagnoses can practice to improve their physical and mental conditions [1,6]. Extensive research studies have demonstrated the beneficial effects of TC programs on different aspects, including flexibility, range of motion, muscle tone, strength, posture, balance, walking, psychological wellbeing, stress reduction, and quality of life [1,6].In the last decade, an increasing number of studies have been conducted to investigate whether and how the human brain might respond to TC practice, assessed by using a variety of neuroimaging techniques which include the following. Functional near-infrared spectroscopy (FNIRS) is a cost-effective, wearable neuro-imaging technology that can safely assess the real-time brain activity during physical performance by monitor the hemodynamic response in the brain cortex using near-infrared light sources and detectors placed

“…Previous neuroimaging studies showed that TCC interventions can reshape the human brain structure and can lead to alterations of functional brain patterns, which, in turn, might foster the improvement of cognitive performance ( 34 ). For instance, in the study of Yue and colleagues ( 35 ), 42 healthy elderly women were assigned to two groups (TCC group and walking group) and underwent a cognitive assessment, as well as a functional magnetic resonance imaging to quantify between-group differences in brain structure and resting-state functional connectivity. In the above-mentioned study, it was noticed (i) that episodic memory in the TCC group was superior to that of the walking group, (ii) that the TCC group exhibited a higher gray matter density in the inferior and medial temporal regions and higher values of regional homogeneity in temporal regions as compared to the walking groups, and (iii) that neurobehavioural relationships exist (i.e., the correlation between gray matter density of the left hippocampus and episodic memory performance).…”

BackgroundTai Chi Chuan (TCC) is an effective method for delaying cognitive decline in older adults. However, in older adults, the association between long-term TCC practice and working memory updating has not been extensively studied.ObjectiveThis cross-sectional study investigated how updating function operationalized via Reaction Times (RTs) and Accuracy Rates (ARs) of N-Back tasks being measured in a laboratory setting is related to long term practice of TCC.MethodsTwenty-six healthy elderly people participated in this experiment. According to the duration of time TCC was practiced, 13 subjects in the TCC group had more than 5 years of experience with TCC exercise, and 13 elderly subjects who had not been systematically exposed to mind-body exercise were assigned to the control group. The N-back task was administered to every participant to evaluate the updating function.ResultsThe TCC group had faster RTs than the control group (p < 0.05). For the 1-back task, the TCC group showed faster RTs than the control group; for the 2-back task, the TCC group exhibited faster RTs than the control group. The TCC group had higher ARs than the control group (p < 0.05). For the 1-back task, the TCC group showed higher ARs than the control group; for the 2-back task, the TCC group exhibited higher ARs than the control group.ConclusionsLong-term TCC practitioners exhibit a better updating function as compared to controls who did not practice TCC. Thus, our findings suggest that long-term TCC positively influences the updating function of older adults, making it, in turn, an effective mind-body exercise to maintain specific aspects of cognitive functioning.

“…Very few studies have investigated the differential effects of exercise type on cognitive function in elderly populations ( Demurtas et al, 2020 ). A cross-sectional study was recently published ( Yue et al, 2020 ), indicating that as compared to older adults who engaged in brisk walking for at least 5 years (60 min × 5 times per week) Tai Chi practitioners demonstrated significantly better behavioral measure/cognitive function (delayed recall-memory function) and greater hippocampus. Researchers concluded that such superior effects may be attributed to complexity of Tai Chi movements (motor-coordinative training and movement sequence) and mindfulness-based training.…”

PurposeThe aim of this study was to investigate the differential effects of Tai Chi vs. brisk walking on cognitive function among individuals aged 60 and greater.Patients and MethodsFor participant recruitment, a health talk was arranged at two communities in which two different exercise modalities (Tai Chi and brisk walking) were assigned to participants of each community free of charge. The intervention programs lasted 10 weeks, with three 60-min training sessions per week. General cognitive ability and specific cognitive outcomes were measured using the Chinese version of the Montreal Cognitive Assessment (MoCA).ResultsA significant interaction on total scores of the MoCA was observed (F = 11.15, p < 0.05). Post hoc analysis indicated significant improvements on general cognitive performance as measured in performance on the MoCA for both exercise groups at the end of 10 weeks. A significant interaction was only observed on the delayed recall sub-domain (F = 12.93, p < 0.001). Results from post hoc analysis indicate that the Tai Chi group had a significantly better memory performance relative to brisk walking group (p < 0.05). Specifically, significant improvement was observed in Tai Chi group (p < 0.05), but not in the brisk walking group. Both exercise groups demonstrated significant improvements from baseline to Week 10, which emerged in visualspatial ability (p < 0.05) and attention performance (p < 0.001). Lastly, animal naming and orientation significantly benefited from brisk walking (p < 0.05) and Tai Chi training (p < 0.05), respectively.ConclusionTai Chi and brisk walking as the most commonly used, culture-specific mind-body exercise method have been proven to be effective in improving general cognitive performance and specific cognitive domains. Furthermore, differential effects of two different exercise modalities on cognitive domains were observed, which has provided insightful information for customized exercise programs. Finally, aging individuals who are experiencing cognitive decline should either take Tai Chi classes regularly or engage in brisk walking, which could contribute to brain health.
