摘　　要：目的分析基于减负的运动方式对单纯性肥胖患者膝关节的保护作用。方法本研究为随机对照试验,选取2021年4月至2022年4月在广州医科大学附属番禺中心医院就诊的所有符合纳排标准的60例单纯性肥胖患者为研究对象,采用随机信封法分为功率自行车组(减负,30例)和运动平板组(非减负,30例),在院进行高强度间歇运动训练:先慢速热身1 min,后快速运动3 min,再休息1 min,重复2个循环为1组,3组/次,5次/周,连续训练12周。除此之外,患者不再参加其他体育运动,并保持原有饮食习惯和模式不变。干预前后分别测定两组体重指数和体脂百分比,统计出现膝痛的例数,用磁共振测量关节软骨体积,每次训练前和训练后均用电子体温计测量膝关节局部皮温,采用t检验、χ2检验、秩和检验比较两组干预前后各项指标差异,分析基于减负的运动方式对单纯性肥胖患者膝关节的保护作用。结果干预前两组性别、年龄、身高、体重等基线资料差异均无统计学意义(均P>0.05)。干预后两组体重指数、体脂百分比、膝关节软骨体积均显著低于干预前,膝痛发生率、膝关节局部皮温均显著高于干预前(均P<0.001)。干预后功率自行车组膝痛发生率、膝关节软骨体积减小及局部皮温增高均显著低于运动平板组[16.67%比100%、0.12(0.05,0.27)比1.68(1.15,2.21)cm3、(0.17±0.09)比(0.64±0.15)℃](均P<0.001);两组体重指数、体脂百分比差异均无统计学意义(均P>0.05)。结论基于减负的运动方式对单纯性肥胖患者的膝关节存在保护作用,能够避免膝关节软骨体积减小及局部皮温增高,减少疼痛发生。Objective To analyze the protective effect of weight-loss based exercises on the knee joints of patients with simple obesity.Methods This study was a randomized controlled trial,60 patients with simple obesity who met the inclusion and exclusion criteria and treated at the Affiliated Panyu Central Hospital of Guangzhou Medical University from April 2021 to April 2022 were selected as subjects.The patients were randomly divided into a power bicycle group(weight-loss,30 cases)and a moving treadmill training group(non-weight-loss,30 cases)using the random envelope method.High intensity interval exercise training was conducted in the hospital:slow warm-up for 1 minute,followed by rapid exercise for 3 minutes,and then rest for 1 minute.Repeated this cycle twice to form one set,and to perform 3 sets per session,5 times per week,for a continuous training of 12 weeks.In addition,patients were not allowed to participate in other sports activities,and they should maintain their original dietary habits and patterns unchanged.Body mass index and body fat percentage were measured before and after treatment,and the cases with knee pain were recorded.The volume of knee cartilage was measured using magnetic resonance imaging.The local skin temperature of the knee was measured using an electronic thermometer before and after each training session.The t-tests,Pearson-tests and Mann-Whitney U tests were used to compare the differences in the above indicators between two groups before and after intervention to analyze the protective effect of weight-loss based exercise on the knee joints of patients with simple obesity.Results There was no statistically significant difference in baseline data such as gender,age,height,and weight between the two groups before the intervention(all P>0.05).After the intervention,the body mass index,percentage of body fat,and knee cartilage volume of both groups were significantly lower than before the intervention,and the incidence of knee pain and local skin temperature of knee were significantly high
