摘要
目的:观察瑜珈对原发性痛经女大学生子宫血流的影响,为痛经患者瑜伽锻炼提供理论和实践依据。方法:以温州医学院20名原发性痛经女大学生为研究对象,随机分为实验组(n=11)和对照组(n=9)。实验组进行3个月的瑜伽练习,每周3次,每次1h;对照组除了不练习瑜伽,生活和学习规律与实验组相近。运用彩色多普勒超声仪在实验前、实验2个月和实验3个月分别检测受试者月经来潮24h内子宫动脉和弓状动脉的阻力指数(RI)、搏动指数(PI)、血流峰值比(S/D)的变化;同时对实验前和实验后痛经疼痛程度进行评分。结果:2个月瑜伽锻炼后,实验组弓状动脉S/D值显著低于实验前(P<0.05);3个月锻炼后,实验组弓状动脉S/D、RI、PI,子宫动脉S/D、RI以及疼痛程度都较实验前下降(P<0.05),其中,弓状动脉RI、PI和子宫动脉S/D、RI还低于实验2个月(P<0.05)。与对照组比较,实验组弓状动脉RI显著降低(P<0.05)。结论:瑜伽运动可降低子宫血管血流的阻力,改善子宫血液循环,有助于缓解痛经症状。
In order to investigate effects of Yago on uterine blood flow of female college students in primary dysmenorrhea,20 female college students in primary dysmenorrhea from Wenzhou Medical College were individed into two groups randomly,experiment group（n=11） did 3-month yoga exercise,3 times a week,1 hour each time,including the warm-up,the basic exercise and the relaxation,control group（n=9） to the experimental group in learning,living habits similar,except for Yago exercise.Systolic phase/diastolic phase（S/D）,resistent index（RI）,pulsatility index（PI） of arcuate artery and uterine artery were detected by color Doppler ultrasound instrument,within the first day of menstruation,before the experiment,and after 2-month,3-month exercise.Result： Arcuate artery S/D after 2-month exercise was lower than before experiment significant（P0.05）.Arcuate artery S/D,RI,PI and uterine artery S/D,RI,and the degree of pain after 3-month were lower than before experiment significant（P0.05）.Arcuate artery＇s RI,PI and uterine artery S/D,RI after 3-month were lower than after 2-month significant（P0.05）.Furthermore,Arcuate and uterine artery RI were lower than the control group（P0.05）.The results indicated that Yoga cloud decrease resistance of uterine blood vessel pressure,improve uterine blood circulation,and help for lessening the degree of pain of primary dysmenorrhea.
