Qigong, a self-healing art focused on the mind-body connection, promotes mind relaxation, eliminates tensions, focuses consciousness, and enhances athletes' mental quality. It draws ample attention on the athletics field because unlike intense sports, ”relaxation, silence and spontaneity” are the key principles of achieving progress in this practice. Entering into a state of silence is a fundamental aspect of advanced Qigong practice. This study aims to explore the meaning of ”silence” and its relationship to changes in brain waves as measured by an electroencephalogram (EGG). The analysis encompasses the thorough review of relevant literature and and investigation of the mechanism between body and mind from physiological point of view. The conclusions of this study are explained as: 1) dynamic and static status of human body and mind; 2) regulating body health and harmony through the state of silence; and 3) promoting better athletic performance with the practice of the state of silence of Qigong.
