This study was conducted to determine whether 24-style Taijiquan (24TJQ) exhibits measurable psychological and physiological effects. Twenty-two middle-aged female subjects performed 24TJQ and cycle ergometry exercises at the same intensity determined by the same heart rate during 2 exercises. Electroencephalography and Profile of Mood State (POMS) were monitored before and after 2 exercises. The responses to 24TJQ exercise were different from those to cycle ergometry exercise when the heart rate returned to the resting level: (1) alpha increased and theta decreased significantly in the frontal region, while theta decreased significantly in the central and occipital regions; (2) in the POMS test, an improved positive mood was found following 2 exercises, while negative mood was suppressed following 24TJQ exercise; (3) significant correlations were found between the increased alpha in the frontal region, the decreased theta in the central or occipital region and the vigor of the POMS test. These results suggest that 24TJQ exercise induced a resting awakening state and exhibited a relaxing effect on both mind and body.
