| Objective: This study intends to organize twenty-four Taijiquan exercises in the middle-aged and elderly,and regularly measure and collect experimental data(atherosclerosis test,central arterial pressure test,body composition,SCL-90 scale,autonomic balance ability)The index data before and after comparison and analysis of the correlation between the indicators.The purpose of this study is to verify the positive effect of twenty-four types of Taijiquan on the improvement of atherosclerosis in middle-aged and elderly people,and to elucidate the influence of body composition and emotional and psychological changes on atherosclerosis,and to explore its mechanism of influence through the analysis and discussion of experimental data,For the elderly in twenty-four Taijiquan practice put forward scientific proposals.Methodology: A total of 45 middle-aged and elderly adults were enrolled in this study.Subjects were selected from the Linhe Village,Guangzhou.Their ages ranged from 45 to 60,and they have been training to practice the twenty-four Taijiquan for eight months.The subjects are required to practice three times a week collectively for one hour(about twenty-four times a full set of tai chi)and practice the complete twenty-four tai chi at least three times a day for the rest of the year.Symptom Checklist 90(SCL90),test body composition,atherosclerosis assessment,and cardiac function tests were administered to the subjects before and after the experiment.Using SPSS statistical software to compare and analyze the data.Results:(1)The CF-PWV of the subjects before and after the experiment was significantly different(P <0.05).The main manifestations of CF-PWV were markedly decreased and the arterial stiffness was relieved.(2)There was no significant change in the number of abnormalities of the reflex wave enhancement index(AIx)before and after the experiment.(3)Subjects before and after the test to reduce the number of excessive blood pressure.(4)The data of body composition before and after the experiment improved,body fat percentage,abdominal fat percentage and muscle mass obviously improved,with significant difference before and after the experiment(P <0.05);before and after the BMI and visceral fat rate(P> 0.05).Before the experiment,CF-PWV had a strong correlation with body fat percentage(P <0.01).CF-PWV had a strong correlation with abdominal fat percentage and visceral fat percentage before and after the experiment(P <0.05),the correlation coefficients were positive,showing a positive correlation.(5)There were significant differences in the results of SCL-90 before and after the experiment(P <0.05).Symptoms of somatization,depression,anxiety and other four factors(sleep,diet)were alleviated.Somatization,depression,anxiety and other factors before and after the experiment were all significantly correlated with CF-PWV(P <0.01).Other post-experiment showed a strong correlation with CF-PWV(P <0.05).Correlation coefficients are positive,showing a positive correlation.Conclusion:(1)Long-term practice Twenty-four types of Taijiquan atherosclerosis in the elderly have a significant positive effect.(2)Long-term practice Twenty-four types of Taijiquan can improve the body composition of the elderly,mainly in reducing body fat rate,reduce the rate of abdominal fat and visceral fat decreased.Long-term practice Twenty-four types of Tai Chi on the negative emotions and psychology have significantly improved,effectively reduce the subjective physical discomfort,improve depression,anxiety,promote sleep and increase appetite.(4)fat content and atherosclerosis are closely related to reduce the fat content can improve atherosclerosis.(5)emotional and arteriosclerosis are closely related to improve the negative emotions have a positive effect on atherosclerosis. |
