Meta-analysis Of The Effect Of Health Qigong Exercise On The Physiological Functions Of Middle-aged And Elderly People

Objective: To systematically evaluate the effectiveness of Health Qigong exercise on the physical function of middle-aged and elderly people,and to perform effect test by meta-analysis.Methods:Retrieving the Randomized Controlled Trail(RCT)literature on the effects of Health Qigong exercise on the physical function of middle-aged and elderly people in Pubmed,Web of Science database,and China Journal Full-text Database(CNKI)and Wanfang Medical Data Knowledge Platform.Download,search time limit for each journal from the date of publication of the literature to August 2018,and according to the document inclusion and exclusion criteria for document screening,extracting literature and evaluating the methodological quality of the included literature,and using the Jadad scale The literature was scored,and the literature with score ?1 was selected.Meta-analysis was performed using stata15 software.After the combined analysis of the data of the qigong group and the control group,the forest map and the funnel plot were drawn and the corresponding conclusions were drawn.A total of 15 RCT samples were included in the study,totaling 900 middle-aged and older people,with participants ranging in age from 45 to 75 years and interventions ranging from 2.5 months to 18 months.Results: Meta-analysis showed that the mean difference(SMD)and 95% confidence interval(CI)combined effect values of the six outcomes of blood lipids were: total cholesterol(TC)[SMD=-0.53,95% CI=(-1.10,0.03),P=0.000],triglyceride(TG)[SMD=-0.76,95% CI=(-1.33,-0.20),P=0.000],high density lipoprotein(HDL)[SMD =0.87,95% CI =(0.22,1.53),P = 0.000],low density lipoprotein(LDL)[SMD =-0.21,95% CI =(-1.52,0.09),P = 0.024],high density lipid Protein cholesterol(HDL-C)[SMD=0.69,95% CI=(0.27,1.12),P=0.346],low-density lipoprotein cholesterol(LDL-C)[SMD=-2.18,95% CI=(-3.36),-0.99),P=0.000];there were no significant differences in peripheral T lymphocytes CD3,CD4,CD8,CD4/CD8;pulmonary function vital capacity(VC),forced expiratory vital capacity(FVC)The mean difference(SMD)and 95% confidence interval(CI)of the two indicators are(VC): [SMD=0.67,95% CI=(0.21,1.12),P=0.076],(FVC): [SMD= 1.03,95% CI =(0.07,1.99),P = 0.000];mean systolic blood pressure(SBP)in blood pressure(SMD)and 95% confidence interval(CI)were [SMD =-0.31,95% CI =(-0.50,-0.11),p=0.362];mean(SMD)of heart rate(HR)indicators and 95% confidence interval(C I)is [SMD=-0.47,95% CI=(-0.88,-0.07),p=0.019].Conclusion:Health Qigong practice can improve the blood lipids,lung function,blood pressure and heart rate of middle-aged and elderly people,which can obviously improve lung function and lower blood pressure.However,the intervention of peripheral T lymphocytes is not significant,due to the quality of literature included.The mean value is not high,and the meta-analytic outcome index is not significant enough.The subgroup analysis further shows that Ba Duan Jin exercise for 3 months can significantly improve the lung function of female patients;the different exercises of health Qigong can exercise for a long time.After lowering blood pressure,and performing different exercises for men and women with health and patients for more than 3 months,it will have significant intervention effects on various indicators of blood lipids.Between the limitations of the research,it is recommended to quantify subsequent related subject areas.Experimental research should be improved in the direction of increasing the duration of intervention and controlling the rigor of the experimental process,in order to provide more scientific fitness training guidelines for more people.
