It is well known that practicing Taiji [1] has many health benefits, including lowering of blood pressure, increase in immunity to shingles, relief to osteoarthritis, lowering stress and pain reduction, improvement in the control of Type 2 diabetes, reducing probability of Alzheimer Disease, and general improvement to overall health [2].\u00a0 Practicing Taiji also can help the elderly with depression [3], help people with Parkinson Disease [4], and provide psychological benefits [5].\u00a0 These studies show that practicing Taiji can result in health and behavior changes at a macroscopic physical and emotional level of the Taiji practitioners.\u00a0 Until recently, there has not been any study investigating the brain structural (neural) changes underlying the health and behavior changes associated with practicing Taiji.\u00a0 This article reports the results of a recent research study that shows that practicing Taiji results in increased cortical thicknesses of the brain.<\/p>\n
<\/p>\n
A group of scientists associated with several research centers in Beijing (e.g., Magnetic Resonance Imaging Research Center, Psychology Research Center, and Psychiatry Research Center)\u00a0 published a paper “Can Taichi Reshape the Brain?\u00a0 A Brain Morphometry Study” in April 2013 in the journal PLOS ONE, which is an open access peer-reviewed scientific journal published by the Public Library of Science. [6]<\/p>\n
In this study, they compared a group 22 experienced Taiji practitioners [age:\u00a0 52 (plus or minus 6 years), 7 males, 14 (plus or minus 8) years of practicing Taiji] and a control group of 18 people [age:\u00a0 54 (plus or minus 8) years, 8 males] who do not engage in physical, yoga, or meditation exercises.\u00a0 The Taiji practitioners practice Taiji from 30 to 90 minutes per session of practice, with the majority having daily practice.\u00a0 Other than this difference in exercises, the two groups are similar in characteristics, including with comparable education experience.<\/p>\n
From analysis of MRI results, they found that there are statistically significant differences in the cortical thicknesses of various parts of the brain.\u00a0 For example, these include:<\/p>\n
Before the MRI sessions, the research team also had the participants completed an Attention Network Test (ANT), a test that measures different behavioral aspects of attention including alerting, orienting and executive attention (working memory related to performance of real-world cognitive tasks) based on the Attention Network theory [7].\u00a0 They found that the Taiji group performed better in the ANT and there is close correlation between the ANT results and the larger cortical thicknesses of the Taiji group.<\/p>\n
From earlier studies by others, we know that meditation, yoga and aerobic exercises can result in increased cortical thicknesses.\u00a0 The current study found similar increased cortical thicknesses from practicing Taiji.\u00a0 Since we know that in spite of Taiji in general being a soft, slow, and gentle exercise, it is an aerobic exercise.\u00a0 Furthermore, Taiji is also called moving meditation, in the sense that the mind is also in a relaxed meditative mode involved in deep and relaxed breathing.\u00a0 Therefore, practicing Taiji can give rise to similar increased cortical thicknesses as from practicing aerobic or meditation exercises should not be surprising at all.<\/p>\n
The researchers also found that the amount of reshaping of the brain depends more on the intensity of the Taiji practice (i.e., frequency and duration of each practice session) than on the number of years that the experienced practitioner has practiced Taiji.\u00a0 This has an important implication that you do not necessarily need to have practiced Taiji for a very large number of years before you can get perhaps almost similar kinds of health benefits as someone who has practiced Taiji for many, many years, as long as the intensity of the practice has been significant.<\/p>\n
The results of this new research is very important, because it provides a deeper level of understanding of the physiological impacts on a human body from practicing Taiji.\u00a0 However, the current study does not shed any light on the impacts on the cellular level, which future studies should be able to provide.\u00a0 I want to end this article by pointing out that there is a possibility the differences in cortical thicknesses found in this study could be due to the fact that by chance there were differences on the cortical thicknesses of the people in the two groups, since the differences were not the result from the Taiji exercises during the duration of this study.<\/p>\n
