Objectives: The aim of this pilot study is to investigate qigong as a training method to treat diseases and improve the quality of life. Methods: We used a controlled clinical study in this research. qigong group(n=34) practiced the zhan zhuang gong for 2 minutes. Control group(n=33) did low intensity walking for 2 minutes. Changes of grip strength, heart rate and rating of perceieved exertion were measured before and after treatment. Paired t-tests and independent t-tests were applied for statistical analysis. Results: Qigong group showed significant improvement in grip strength(p<0.05), whereas the control group showed insignificant changes(p<0.05). Both groups demonstrate significant changes in heart rate(p<0.05). In rating of perceieved exertion, significant difference showed between groups(p<0.05). Conclusions: The zhan zhuang gong, a kind of qigong improved grip strength by 2 minutes of practice. We may conclude that zhan zhuang gong could be a method of improving physical strength.
