Investigation And Analysis Of Knee Joint Function Of Taijiquan Practitioners In Some Urban Areas Of Shanghai

Pur Pose:To understand the distribution characteristics of knee joint function of Taijiquan Practitioners in different Personal situations and exercise modes through a questionnaire survey of knee joint function of Taijiquan Practitioners in some urban areas of Shanghai,and to ex Plore the discrimination of knee joint function of Taijiquan Practitioners.The model Provides quantitative data for scientific Taijiquan exercise,and Provides a reference for Taijiquan as a Prescri Ption for knee joint exercise.Methods: A questionnaire survey was conducted to randomly select 1750 Taijiquans and use the Irrgang Knee Movement Function Scale to investigate.The data management a PPlication EPidata3.1 was double-recorded,and then the statistical analysis of the data was Performed by SPSS24.0 software with ?=0.05 as the test level.Univariate analysis of factors such as age,gender,body mass index,boxing age,learning Pathway,Posture,warm-u P,exercise intensity,and knee Pain before exercise were Performed.Logistic regression analysis was Performed on statistically significant factors.Multi Ple linear regression analysis.Results: 1.Res Ponse rate: 1750 questionnaires were com Pleted in this survey,1703 valid questionnaires,the res Ponse rate was 97.31%,572 males,accounting for 33.0%,and 1131 females,accounting for 67%.2.Reliability and validity test of the scale: The total score of the daily activity ability evaluation system of the Irrgang knee joint investigation system is 0.94,and the KMO value of the validity test is 0.949,indicating that the reliability of the scale is good,in line with this time.Questionnaire analysis requirements.3.Single factor analysis shows:3.1 For men: age,body mass index,learning Pathway,warm-u P time,knee Pain frequency 5 variables of the Irrgang knee joint motor function scale scores were significantly different(P <0.05).3.2 For women: age,body mass index,learning Pathway,exercise frequency,boxing height,warm-u P time,knee Pain frequency,7 variables of Irrgang knee joint motor function scale scores were significantly different(P <0.05).3.4 For the Taijiquan Practitioners: age,body mass index,learning route,exercise frequency,boxing height,warm-u P time,knee Pain frequency,7 variables of Irrgang knee joint motor function scale scores were significantly different(P<0.05).4.Ordered logistic regression shows:4.1 Taijiquan

regression of the degree of influence on life:Taijiquan exerciser with teacher teaching OR value is1.537 times random high exercise,(95% CI: 0.094-0.766),?2= 10.146,P = 0.001.The medium height Posture exercise OR value is 6.50 times that of the random height exercise,(95% CI: 1.532-2.211),?2= 6.28,P = 0.012.5.Establishment of multi Ple linear regression models:5.1 Male Taijiquan Practitioners' multi-element linear regression analysis of knee function: Y = 165.045-14.135X-3.566X-1.803 X + 1.589 X :(where X1 is Pain before exercise,X2 is BMI index,X3 is age,X4 warm-u P time);Y = 65.609-4.964-1.286X-0.767 X :(where X1 is Pain before exercise,X2 is BMI index,and X3 is warming degree);Knee joint function dimension score: Y = 65.609-4.964-1.286X-0.767 X :(where X1 is Pain before exercise,X2 is BMI index,X3 is age,X4 is Taijiquan exercise frequency)5.2 Female Taijiquan Practitioners' multi-element linear regression analysis of knee function: The total score is determined by ste Pwise regression,and the resulting regression model:(Which X1 is whether there is knee Pain,X2 is BMI index,X3 is warm-u P time,X4 age,X5 exercise frequency,X6 learning Path);Sym Ptom dimension:using ste Pwise regression method,the final regression model: X1 is Pain before exercise,X2 is warm-u P time,X3 is age,X4 is BMI index,X5 is taiji exercise frequency);knee joint function dimension: using ste Pwise regression method,the final regression model:(where X1 is Whether it is Pain before exercise,X2 is the BMI index,X3 is the time of each exercise,X4 is the age,and X5 is the exercise frequency of Tai Chi.)Conclusion:1.Whether the knee joint is Painful,age,warm-u P,and BMI index have an effect on knee function of Tai Chi Practitioners before exercise.Whether the knee is Painful before exercise is the main influencing factor.2.Exercise frequency and learning Pathway are the other two influencing factors of knee function of female Tai Chi Practitioners.
