| Objectives:This study will adopt the strict randomized controlled design. Through regularity Baduanjin training, we systematically observed the effect of cardiopulmonary function and the quality of sleep and mood state on stroke in the community elder population with high stroke risk factors. To explore the fitness effect as well as the preventive effect of Baduanjin on stroke in the community elder population with high stroke risk factors.Methods:This trial will be performed at Wufeng, Fengdanbailu and Spring Community Center in Gulou District, Fuzhou City, China. A total of 170 eligible participants will be randomly allocated into intervention group (the Baduanjin group) and control group (general physical activity group). The training scheme of Baduanjin originated from the’Health Qigong Baduanjin Standard’enacted by the State Sports General Administration in 2003. We will employ professional coaches, who have engaged in teaching the college students physical education at the Fujian University of Traditional Chinese Medicine to guide participants’ training. The participants in the Baduanjin group will accept a 12-week Baduanjin training, at the same time the others in the control group will maintain their original physical activity. Primary and secondary outcomes will be measured at baseline, end of 12-week intervention and after an additional 12-week follow-up period. Statistical analyses will be performed using SPSS 18.0. In descriptive analysis of the sample, the central tendency for the continuous variables will be expressed using mean (standard deviation) or median (interquartile range) for symmetrical distributions; normality will be tested using the Kolmogorov-Smirnov test. Appropriate transformations will be applied in cases of a non-normal distribution. The statistical significance is defined as two-sided Pvalue of< 0.05.Results:The results show that the Baduanjin group in improving the chase volume, the sleep quality and mood state are superior to control group. In terms of cardiac structure and function, left ventricular posterior wall thickness in Baduanjin group has a tendency to reduce, but the difference is not obvious (P>0.05) after the intervention period and follow-up period. The exploratory analysis on cardiac structure and function found that the male of left ventricular ejection fraction had significant difference (P=0.008<0.05) between the two groups, at the end of the follow-up period. The results of left ventricular posterior wall thickness in Baduanjin group among female and hypertension patients have a tendency to reduce, but the difference is not obvious (P>0.05) after the intervention period and follow-up period. The result of pulmonary function found the maximun minute ventilation between two groups had significant difference (P=0.009<0.05) after the follow-up period. Minute ventilation of pulmonary function has a rising trend, but the difference is not obvious (P>0.05). The exploratory analysis on pulmonary function found that female’s the maximun minute ventilation between the two groups had significant difference (P=0.034<0.05) at the end of the follow-up period. Male’s minute ventilation and the maximun minute ventilation have rising trend, but the difference is not obvious (P>0.05). There is a significant difference (P=0.034<0.05) on minute ventilation among hypertension patients, the maximun minute ventilation and vital capacity have a rising trend, but the difference is not obvious (P>0.05). After the intervention period and follow-up period, the Pittsburgh sleep quality index (PSQI) score and mood state scale (POMS) have a significant difference (P<0.01).Conclusions:1. Baduanjin can improve the quality of sleep and mood state.2. Baduanjin increase the maximun minute ventilation of pulmonary function, minute ventilation of pulmonary function has a rising trend.3. Baduanjin improve left ventricular ejection fraction in the male, left ventilation posterior wall thickness has a tendency to reduce. |
