Effects Of Pilates Combined With Respiratory Muscle Training On Lung Function And Body Posture Of Female College Students

Research purposes: Due to long-term desk study,long-term influence on computers,poor sitting posture,lack of exercise and other factors,a high proportion of college students have abnormal upright postures.Among them,the more typical features are head tilt,round shoulders,high and low shoulders.,Pelvic leaning forward,etc.Existing studies have confirmed that there is a certain connection between poor body posture and lung function.Based on this,this study uses Pilates as a core training method to explore the effects of Pilates exercise on female college students’ lung function and body posture control ability through dual training of core muscles and respiratory muscles.Research method: This study recruited 100 female college students from Nanjing Normal University who had not participated in any body posture correction and pulmonary function targeted training.Through screening,66 recruits met the criteria.The subjects were randomly divided into 3 groups(22persons in each group)by computer random allocation method,namely the experimental intervention group,the active control group,and the blank control group.Collected before the experiment: 1)Basic information of the subject(gender,age,height,weight,etc.);2)Information about healthy lifestyle;3)Body posture assessment(head tilt angle,round shoulder angle,distance between the acromion,etc.)Pelvis anteversion angle,pelvic anteversion dimension);4)lung function evaluation data;5)balance ability.The experimental intervention group received Pilates combined with a breathing exerciser for training,the active control group only received Pilates training,and the blank control group received no training and only needed to maintain daily routines.Exercise intervention is performed 3 times a week,60 minutes each time,lasting 15 weeks(8 weeks offline,7 weeks online),a total of 45 times.All subjects will collect relevant data before the experiment(0 weeks),during(8 weeks),and after(15 weeks).Use SPSS24.0 version statistical software to analyze and process the experimental data.Previously measured data is a covariate,using single-factor analysis of covariance to explore the inter-group effect on each test indicator in the mid-and late-stage tests,and using single-factor repeated measures analysis of variance for single-group time effects.For the convenience of description,the experimental intervention group is referred to as PRT in the following article,the active control group is referred to as PLT,and the blank control group is referred to as CON.Research results: Pulmonary function indicators: FVC(F(2,58)=3.51,p=.036,partial η ~2 =.11),MV(F(2,42)=2.62,p<.05,partial η ~2 =.11)TV(F(2,58)= 4.27,p=.02,partialη~2 =.128)is significantly higher than the PLT group;with time,PRT is 1% FEV compared to PLT(F(2,42)=10.2,p<.05,partial η ~2 =.327).The PRT group has a larger increase in PREF(F(2,42)=5.62,p<.05,partialη~2=.211,mean difference=.700),TV(F(2,58)=4.27,p<.05,partialη~2 =.128,mean difference=0.28)There is a significant improvement.Physical posture indicators: After the intervention,PRT and PLT have round shoulders(F(2,42)=8.13,p<.05,partialη~2 =.022),pelvic anterior inclination angle(F(2,42)=8.29,p<.05,partialη~2=.283)were significantly improved,but there was no significant difference between the two groups;with time,the round shoulder angle between PRT and PLT(F(2,42)=8.13,p<.05,partial η ~2=.022,mean difference = 11.57),significantly improved,pelvic anterior tilt dimensions(PRT post-test: F(2,58)=7.08,p<.05,partial η ~2 =.252,PLT post-test:F(2,38)=7.99,Abstract Ⅱ p<.05,partialη~2=.296,mean difference=1.02)has a significant decrease,and the improvement of PRT is significantly higher than that of PLT,and there is no significant intra-group difference in CON.In the static balance test,PRT and CON post-test with closed eyes and one-legged standing(Y-axis displacement difference)(F(2,58)=4.24,p=.02,partialη~2=.128)had a significant between-group effect,PRT Obviously smaller than COV(mean difference=-29.76);With the change of intervention time,PRT and PLT will shake the amplitude(Y-axis displacement difference)and left-right shaking amplitude(X-axis displacement difference)when standing on one leg with eyes open and closed.),all have a significant decrease,and the pressure center of gravity swing area(envelope area)is reduced but not significant,and CON has no significant intra-group difference.Changes in physical flexibility indicators: PRT and CON(F(2,58)=5.50,p<.05,partial η ~2 =.159)have significant between-group effects,and PRT is significantly higher than CON(mean difference=2.64);PRT(F(2,42)=9.19,p<.01,partial η ~2 =.304)has a significant improvement over time,but there is no significant intra-group difference in CON.Changes in VAS pain scores: The VAS pain scores of the three groups all showed a downward trend over time,among which PLT and CON pain scores(PLT:F(2,38)=8.18,p<.05,partialη~2=.301,CON: F(2,38)=6.53,p<.05,partialη~2=.256)has a significant reduction,but the reduction of PLT is greater than that of CON(PLT mean difference=1.12,CON mean difference=0.8).Research conclusions: 15 weeks of Pilates combined with respiratory muscle training and only Pilates training can improve the posture abnormalities of female college students such as round shoulders and lower abdomen caused by anterior pelvic tilt,but Pilates combined with respiratory muscle training is effective The effect of posture improvement is more prominent.Pilates combined with breathing muscle training can significantly improve the overall level of lung function,but Pilates training alone has no obvious effect on improving lung function.Pilates combined with breathing muscle training and only Pilates training can improve the static balance ability of female college students.
