Study of prevention of cardiac function disorder due to immediate entry into highlands by qigong exercise

Change of cardiac function might happen to persons living on plains who quickly enter the Tibetan plateau. Before entering the highlands, 66 persons were divided into two groups: the qigong group, including 32 young men who had taken exercise of Qiyuan Qigong for 4 weeks. The control group, including 34 persons did exercise to radio music. The results
showed that in the highlands, the attack rate of altitude stress and abnormal blood pressure, heart rate, oxygen consumption, and the weighted integral value of symptoms due to highlands, were statistically lower in the qigong group than in the control group: the index of the cardiac function of both the two groups statistically lowered at Tibet on plateau and TPR in the qigong group was statistically lower than in the control group, but the indexes such as sI, cI, Ac, Hl of the qigong group were statistically higher than those of the control group. It is suggested that exercise with qigong should prevent cardiac function disorder due to highland and needs in-depth studies.
