Efficacy of Taiji Training as a Program for Stress Prevention

Background: Excessive exposure to psychosocial stress can be a potent trigger for somatic diseases and psychological disorders, a cause for missing work, and eventually lead to high economic loss. Therefore, for health and economic reasons the assessment of effectiveness of stress preventive interventions is of high relevance. According to several clinical studies, Taiji, a Chinese form of mindful and gentle movements, can significantly reduce symptoms of somatic diseases and psychological disorders. Some recently conducted Taiji-studies with healthy subjects indicate a stress protective effect. However, the stress protective impact of Taiji regarding psychosocial stress has not yet been examined. Objective: To investigate the efficacy of a 12 week Taiji training as a stress prevention program by measuring psychosocial stress reactivity in a laboratory setting, as well as the subjective perception of stress and coping-resources in daily life of 70 healthy volunteers. Hypothesis: Healthy subjects attending a 12 week Taiji course (frequency: twice a week for 1h) will show significantly reduced psychobiological reactivity, decreased stress perception and increased coping-resources on a standardized psychosocial stress test compared with healthy subject of the waiting list.
