Preliminary Study on the Characteristics of EEG Signals before and after Tai Chi and Yoga Practice

Описание: Abstract: Tai Chi and Yoga are traditional Oriental fitness activities, both of which have a history of more than one thousand years. It has been shown that these two types of exercise have an auxiliary therapeutic effect on the human body and mind. However, due to the limitation of measurement equipment, there are few studies on the effects and mechanisms of the two types of exercise on human nerves. Based on wearable EEG devices, this study explored the changes in EEG signals before and after exercise in Tai Chi and yoga practitioners. Through the feature extraction process, different characteristics including the time domain, frequency domain, and nonlinear dynamic of EEG signals were analyzed before and after the participants ' exercise. The analysis results show that these two types of exercise have significant effects on relaxation, meditation, and other characteristic signals of human EEG signals. The EEG signal analysis proposed in this study can be used to explore the mechanism of the influence of traditional sports on the human body and provide scientific evidence for the fitness mechanism of traditional sports.
