摘　　要：目的分析两种运动强度规定方法制订的运动处方对代谢综合征(metabolic syndrome,MS)的临床干预效果及差异。方法选择2022年12月至2024年1月在太原市中心医院招募的MS患者49例,随机分为标准化组(n=24)和个体化组(n=25)。所有患者在治疗前后均进行心肺运动试验(cardiopulmonary exercise test,CPET)以测量主要指标,用于观测和制订运动处方,次要指标包括人体参数、人体成分和代谢指标的测定。标准化组基于心率储备,个体化组基于通气阈值规定运动强度,两组患者均进行12周运动频率一致的等能量消耗运动干预。结果干预后,两组较干预前均有效降低患者腰围(WC)、体质量指数(BMI)、体脂肪相关参数及收缩压(P<0.05),个体化组对WC、BMI和体脂肪参数的改善幅度更高(P<0.05);两组较干预前均有效提高患者峰值摄氧量(PeakVO_(2))、峰值负荷功率(PeakWR)、峰值代谢当量(PeakMets)和峰值呼吸交换率(PeakRER)(P<0.05),个体化组还有效提高患者峰值心率(HRpeak)、峰值氧脉搏(PeakVO_(2)/HR)和最大通气量(MVV)(P<0.05)。干预前,两组PeakVO_(2)和PeakMets差异有统计学意义(P<0.05),标准化组高于个体化组,干预后组间差异均无统计学意义(P>0.05),个体化组对以上指标的改善幅度均高于标准化组。结论即使处于中等运动强度领域,基于CPET的两种渐进式运动处方都可有效改善MS患者的健康相关指标,通气阈值个体化方法相比最大生理值标准化方法更具优势。Objective To compare the effects of two exercise intensities on metabolic syndrome(MS).Methods Forty-nine MS patients hospitalized in Taiyuan Central Hospital from December,2022 to January 2024 were selected and randomly divided into two groups:a standard group(n=24)and individual group(n=25).All patients underwent cardiopulmonary exercise test(CPET)before and after treatment,collecting major indexes including body parameter,body component,and metabolic indicator for prescribing exercise programs.The standard group was trained with exercise intensity prescribed on heart rate reserve,while the individual group received the exercise with intensity prescribed on ventilatory threshold.Both groups received equal energy consumption exercise intervention with the same exercise frequency for 12 weeks.Results The two groups demonstrated significant improvements in waist circumference(WC),body mass index(BMI),body fat related indexes,and systolic blood pressure after intervention(P<0.05).The individual group showed significant improvements inWC,BMI and body fat related indexes as compared to the standard group(P<0.05).Both groups showed significant improvements in peak oxygen uptake,(PeakVO_(2)),peak load power(Peak WR),peak metabolic equivalent(PeakMets),and peak respiratory exchange ratio(Peak RER)after intervention(P<0.05).The individual group presented significant improvements in peak heart rate(HRpeak),peak oxygen pulse(Peak VO_(2)/HR),and maximum voluntary ventilation(MVV)(P<0.05)after intervention.Before intervention,the standard group demonstrated significantly higher 19levels in PeakVO_(2) and Peak MET compared to the individual group(P<0.05),but after intervention the two groups showed no significant differences in the two indexes.After the intervention,the individual group demonstrated insignificant improvements in all indexes compared to the standard group(P>0.05).Conclusions Both exercise prescriptions based on CPET can effectively improve the health-related indicators of MS patients on condition of moderate e
