【摘要】：研究目的本研究拟通过双能X射线吸收扫描仪和氢质子磁共振波谱技术对糖尿病前期非酒精性脂肪肝中老年女性身体成分和肝脏脂肪含量进行定量评估,进而评价24周北欧健步走运动是否能够改善糖尿病前期非酒精性脂肪肝,为更好的利用有氧运动干预和控制非酒精性脂肪肝提供参考依据。研究方法1.研究对象:以上海市杨浦区糖尿病前期非酒精性脂肪肝中老年女性40名为研究对象,随机分成运动组和对照组,每组20人。研究期间有7人因病因事退出,共有17名运动组(平均年龄60.0±3.7岁)和16名对照组(平均年龄58.8±4.2岁)完成本研究。受试者均自愿参与研究,签署知情同意书。2.干预方案:运动方式以北欧健步走有氧运动为主,结合拉伸训练和太极拳作为准备练习和整理活动。受试者在社区运动场地以群练的形式进行运动,运动强度从最大摄氧量的60%逐步提升至75%,运动时间由每次45分钟逐步提升至每次60分钟,次数由每周3次逐步提升至每周5次,持续24周。3.宣传教育:对照组将接受包括慢性病防治、健康饮食教育以及运动指导的宣传教育并被告知保持原有的体力活动水平和生活、饮食方式不变。4.测试指标:在干预前后分别采用双能X射线吸收扫描仪进行检测受试者体脂率;上肢、下肢、躯干、腰腹部、腹臀部、全身的脂肪含量和瘦体重;采用超导型磁共振成像系统对肝脏脂肪含量进行非侵入性检测。研究结果1.24周北欧健步走干预后,运动组体脂率、体重较干预前降低有显著统计学意义(p0.05);对照组体重较干预前略有升高,但统计学意义不显著(p0.05)。组间比较,运动组体重较对照组呈降低趋势,但统计学意义不显著(p0.05)。2.24周北欧健步走干预后,运动组各部位脂肪含量较干预前降低统计学意义显著(p0.05);对照组除腰腹部外,各部位脂肪含量较干预前升高统计学意义显著(p0.05)。干预后,运动组腰腹部、腹臀部脂肪含量较对照组均降低显著(p0.05)。3.24周北欧健步走干预后,运动组上下肢瘦体重较干预前升高统计学意义显著(p0.05);对照组下肢、躯干、全身瘦体重较干预前降低统计学意义显著(p0.05)。干预后,运动组各部位瘦体重与对照组相比,统计学意义不显著(p0.05)。4.24周北欧健步走干预后,运动组肝脏脂肪含量较干预前降低统计学意义显著(p0.05),对照组肝脏脂肪含量较干预前升高统计学意义显著(p0.05)。组间比较,运动组肝脏脂肪含量较对照组降低统计学意义显著(p0.05)。5.腰腹部脂肪含量与肝脏脂肪含量呈高度相关(R0.7,p0.05);腹臀部脂肪含量与肝脏脂肪含量呈低度相关(R0.4,p0.05)。研究结论1.24周北欧健步走能明显降低体脂率、体重和明显改善中心性肥胖内脏脂肪的堆积,也改善全身脂肪的堆积。2.24周北欧健步走能有效增加上肢瘦体重,提高了运动时机体的能量代谢。3.24周北欧健步走能有效改善非酒精性脂肪肝患者肝脏脂肪堆积情况,对非酒精性脂肪肝的治疗有积极作用。4.腰腹部脂肪含量与肝脏脂肪含量高度相关,表明腰腹部脂肪含量可作为辅助判断非酒精性脂肪肝的生理学指标。
[Abstract]:The purpose of this study is by dual energy X ray scanner and proton magnetic resonance spectroscopy of pre diabetes in nonalcoholic fatty liver disease in elderly female body composition and liver fat content were quantitatively assessed and evaluated 24 weeks of Nordic walking exercise to improve pre diabetes of nonalcoholic fatty liver disease, to better use aerobic exercise intervention and provide reference for the control of non alcoholic fatty liver. Research methods 1. object of study: 40 middle-aged and elderly women with non-alcoholic fatty liver disease in Yangpu District, Shanghai, were randomly divided into exercise group and control group, 20 in each group. During the study, 7 people withdrew from the cause of the disease. A total of 17 sports groups (average age 60 + 3.7 years old) and 16 control groups (average age 58.8 + 4.2 years old) were completed. The subjects voluntarily participated in the study and signed the informed consent. 2. intervention plan: movement to the Nordic walking aerobic exercise, stretching by training and Taijiquan as preparatory exercises and consolidation activities. Subjects in the exercise of community sports training group in the form of exercise intensity from 60% VO2max increased gradually to 75%, the exercise time every 45 minutes up to 60 minutes each time, 3 times a week by the number of up to 5 times a week for 24 weeks. 3. publicity and education: the control group will receive publicity and education including chronic disease prevention, health diet education and sports guidance, and is told to keep the original physical activity level and lifestyle and diet mode unchanged. 4. test index: before and after the intervention by dual energy X ray absorption scanner to detect subjects of body fat rate; the fat content of upper and lower limbs, torso, waist and abdomen, buttocks, abdomen and body weight; non invasive detection of hepatic fat content by superconducting magnetic resonance imaging system. Results 1.24 weeks of Nordic walking exercise group after the intervention, body fat, body weight than before the intervention significantly decreased (P0.05); the control group body weight increased slightly compared with before intervention, but were not significant (P0.05). Compared with the control group, the body weight of the sports group was lower than that of the control group, but the statistical significance was not significant (P0.05). Nordic walking 2.24 weeks after the intervention, the fat content of each part of the exercise group lower than before intervention were statistically significant (P0.05); the control group in addition to the waist and abdomen, fat content in different parts of statistically significantly increased compared with before intervention (P0.05). The fat content in the lumbar abdomen and abdomen of the exercise group was significantly lower than that of the control group (P0.05). 3.24 weeks of Nordic walking intervention, exercise group on lower limb lean body weight compared with before intervention statistically significantly increased (P0.05); control group, lower limbs and trunk lean body weight lower than before intervention were statistically significant (P0.05). After the intervention, the lean body weight of each part of the exercise group was not statistically significant compared with the control group (P0.05). 4.24 weeks of Nordic walking intervention, exercise group liver fat content lower than before intervention were statistically significant (P0.05), the control group of liver fat content compared with before intervention statistically significantly increased (P0.05). Compared with the control group, the fat content of the liver in the exercise group was significantly lower than that in the control group (P0.05). 5. the fat content of the waist and abdomen was highly correlated with the fat content of the liver (R0.7, P0.05), and the fat content in the abdomen and buttocks was correlated with the liver fat content in a low degree (R0.4, P0.05). The conclusion of the study 1.24 weeks walking Nordic can significantly reduce the accumulation of body fat percentage, body weight and improve central obesity, visceral fat, also improve the accumulation of body fat. 2.24 weeks of Nordic walking can effectively increase the upper limb lean body mass, improve the energy metabolism during exercise. 3.24 weeks of Nordic walking can effectively improve the patients with non-alcoholic fatty liver fatty liver, have a positive role in the treatment of nonalcoholic fatty liver disease. 4. the fat content of the waist and abdomen is highly correlated with the fat content of the liver, which indicates that the fat content in the waist and abdomen can be used as a physiological index to judge non-alcoholic fatty liver.
