摘　　要：目的:探讨瑜伽呼吸练习对膈肌力学参数的影响及其与肺功能指标的相关性。方法:该研究为横断面研究。2024年1月10日至4月20日,通过太原市瑜伽协会社交平台招募80名瑜伽练习者(瑜伽>5年组40名,瑜伽≤5年组40名),同期在山西白求恩医院医务工作者中招募40名久坐行为人群(久坐组),利用斑点追踪超声技术评估3组研究对象膈肌运动情况,比较3组研究对象平静呼吸与深吸气状态下膈肌力学参数(膈肌位移、增厚率、应变及应变率);同时检测其肺功能指标,包括用力肺活量(FVC)、第1秒用力呼气容积(FEV 1)以及1秒率(FEV 1/FVC);分析3组研究对象膈肌力学参数及肺功能指标的差异与相关性。结果:3组研究对象性别(χ^(2)=0.346)、年龄(F=1.16)、身高(F=0.45)、体重(F=0.11)、体重指数(F=0.07)比较,差异均无统计学意义(均P>0.05)。平静呼吸时,3组研究对象膈肌位移、增厚率、膈肌应变差异均无统计学意义(F=1.21、2.10、0.23,均P>0.05),瑜伽>5年组膈肌应变率小于其他两组(t=-4.23、-4.10,均P<0.05),瑜伽≤5年组与久坐组膈肌应变率差异无统计学意义(t=-0.06,P>0.05);深吸气状态下,久坐组、瑜伽≤5年组、瑜伽>5年组膈肌位移、增厚率、膈肌应变及应变率均依次增大(F=25.82、60.99、17.29、52.46,均P<0.05)。久坐组、瑜伽≤5年组、瑜伽>5年组FVC、FEV 1、FEV 1/FVC依次增大(F=4.49、7.32、39.71,均P<0.05)。相关性分析结果显示,深吸气状态下,膈肌位移与FVC呈正相关(r=0.290,P<0.05),膈肌位移、增厚率与FEV 1、FEV 1/FVC呈正相关(r=0.333、0.448,0.231、0.599,均P<0.05)。结论:瑜伽训练可能提高膈肌运动能力及效率,改善肺功能;膈肌应变、应变率与肺功能指标FEV 1、FEV 1/FVC呈负相关。Objective To investigate the effects of regular yoga practice on pulmonary function and mechanical parameters of diaphragm.Methods Eighty regular yoga practitioners,including 40 practicing for≤5 year(yoga≤5 years group)and 40 for>5 year(yoga>5 years group)were recruited in Shanxi Norman Bethune Hospital from January 2024 to April 2024;and 40 sedentary subjects were also recruited as the control group.The diaphragmatic motion was evaluated by two-dimensional ultrasound and speckle tracking ultrasound in all subjects,the parameters,including displacement,fractional thickening,strain and strain rate of diaphragm were observed at rest and deep breathing.At the same time,the pulmonary function tests were performed,the indexes including forced vital capacity(FVC),forced expiratory volume in 1 second(FEV 1)and one-second rate(FEV 1/FVC)were measured in all subjects.The mechanical parameters of diaphragm and the pulmonary function were compared among three groups.ResultsThere were no significant differences in gender(χ^(2)=0.346),age(F=1.16),height(F=0.45),weight(F=0.11)and body mass index(BMI)(F=0.07)among the three groups(all P>0.05).At the rest status,there was no significant difference in diaphragm displacement,thickening rate and strain among three groups(F=1.21,2.10 and 0.23,all P>0.05);the strain rate of yoga>5 years group was lower than that of other two groups(t=-4.23、-4.10,all P<0.05);however,there was no significant difference between yoga≤5 years group and control group(t=-0.06,P>0.05).During deep breathing,the increment of displacement,thickening rate,strain and strain rate of diaphragm in yoga>5 years group was larger than that in other tow groups,while the increment of yoga≤5 years group was larger than that in control group(F=25.82,60.99,17.29 and 52.46,all P<0.05);the increment of FVC,FEV 1 and FEV 1/FVC in yoga>5 years group was larger than other two groups,whilc the increment of yoga≤5 years group was larger than that of sedentary group(F=4.49,7.32 and 39.71,all P<0.05).The diaphragmatic d
