So relieving Stress is a must for modern society. Purpose of this study was to explore the effectiveness of Stress relief by Pilates exercise of eight weeks, by brain waves, heart rate variability, and Ryodoraku detecting positive and negative emotional feel-scale autonomic nervous activity and positive and negative emotions of change, to assess Stress relief results. The subjects were 22 sedentary office workers (age 30.50 ± 3.20 yrs, systolic blood Stress 101.31 ± 14.32mmHg, DBP 68.09 ± 9.65mmHg), randomly assigned into experimental group (n = 11) and control group (n = 11). The experimental group involved eight weeks Pilates exercise while control group were not. In the two groups the test begin with Biopac MP150 multifunction physiological signal to acquire Measurements subjects on prefrontal F3, F4 location of brain waves (β-wave, α-wave, θ-wave, δ wave) and heart rate variability (LF, HF, LF / HF) of 10 minutes and capture the first 4-8 minutes for analysis and comparison; Also to measure Ryodoraku value by ME-Pro model (average amount of current, up / down ratio), to assess sympathetic and parasympathetic activity of the change. Psychological indicators are scaled by positive and negative emotions scale (PANAS), exercise-induced feeling of scale (EFI) and the Mood State Scale (POMS) test of the three scale scores before and after the exercise to assess the mood changes and Stress relief results. All information is compared by paired t-test and independent sample t-test group for the difference, setting the significance level as p <.05.The results show: brain waves: In the experimental and control group, the "frontal lobe F3" β wave had significantly decreased (p <.05) comparing to pre-test one, while the control group "frontal F4" of the "θ-wave" post-test value has increased significantly(p <.05) comparing to the pre-test value and the experimental group post-test one. Ryodoraku areas: two "up and down ratio" of pre-test values are greater than "1" and no significant difference between groups (p>.05). However, after involving Pilates exercise of eight weeks in the experimental group, the "up and down ratio " of the post-test value is significantly less than the pre-test value (p <.001), and there is close to" 1 "trend; On the other hand, the control group’s post test value increased and had the deviation trend from the" 1 " (p>.05).Heart rate variability: After the Pilates exercise involved in the experimental group, the "high power" (HF Power ms2) value was measured with upward tendency and was significantly different than the pre-test one and of the control group (p <. 05). In addition, the "low / high frequency power" of experimental group had downward trend in the ratio of the pretest and control group are significant differences (p<.05).Sense of self scale: For the positive and negative emotions scale (PANAS), the results of the experimental group in the "positive mood" score more compared to pre-test and control groups (p<.001), and "negative emotions "score is also significantly decreased (p<.001), while the control group of" positive emotions "and" negative emotions "measured before and after had no significant change (p>.05). The amount of exercise-induced feeling Table (EFI) in the experimental group has reached "calm and relaxing", "energy ecovery" ,"positive emotions" and "physical exhaustion", that were significantly improved in the post-test scores than of pre-test and the control group. IN the Mood State Scale (POMS) results, the experimental group's positive sentiment including "activity", "self-esteem” of the post-test scores were higher than of pretest and the control group. While negative emotions like "anger", "depressed", "confused", "fatigue", "tense" of the post-test scores dropped significantly than of the control group and pre-test. The results summarized by the conclusion of this study: 8 weeks Pilates exercise has reached emotional stability, enhanced the mind of positive thinking, increased parasympathetic activity by physical activity, decreased sympathetic activity that tends to balance the role of the autonomic nervous system to achieve relaxation and Stress relieving.
