摘要：

［摘要］目的：探讨单纯性肥胖患者根据自我感觉进行健步走时运动强度的信度与效度，为制定特异性的运动处方提供依据。方法：选取100名单纯性肥胖患者（BMI>28kg/m²，肥胖组，O组）和100名体质量正常者（BMI<24 kg/m2，体质量正常组，NW组），根据自我感觉选取步速和步幅，分别进行2次健步走运动实验（Test1和Test2），距离为2 km。测量2次实验的平均步速、心率（HR）、最大心率百分比（%HRmax）和主观疲劳感觉（RPE）；通过各指标在Test1和Test2的相关系数(r)检验健步走的重测信度；应用美国运动医学会（ACSM）推荐的改善心肺适能的运动强度标准（60%~90%HRmax）检验健步走的校标关联效度。结果：2次健步走运动实验，组内比较，各指标均无统计学意义（均P>0.05），且r均高于0.9，即重测信度较高；组间比较，2次实验O组步速均低于NW组（均P<0.01），平均HR均高于NW组（均P<0.01），%HRmax高于NW组（均P<0.05），RPE则无统计学意义（均P>0.05）。O组相对运动强度（72%HRmax）达到了ACSM的推荐标准，校标关联效度r=0.731（P<0.01）；NW组相对运动强度（59%HRmax）低于最低推荐值，校标关联效度r=0.351（P>0.05）。结论：根据自我感觉进行健步走的运动强度适用于单纯性肥胖患者，但不适用于体质量正常者。RPE可能是单纯性肥胖患者监控健步走运动强度有价值的指标之一。

Abstract:

Abstract:Objective To explore the reliability and validation of intensity of self-guided brisk walking in simple obesity patients and to provide evidence for formulating special exercise prescription. Methods One hundred simple obesity patients (BMI>28, obese group, O group) and 100 normal weight adults (BMI<24, normal weight group, NW group) performed two tests of 2-km brisk walking on alternate days at a self-guided pace (Test1 and Test2). The average pace, heart rate (HR),percentage of maximal heart rate (%HRmax) and ratings of perceived exertion (RPE) were measured during each test;the retest reliability of brisk walking was conducted by correlation test in all indexes of Test1 and Test2;criterion-related validation was analyzed through the threshold (60%-90%HRmax) recommended for improvements in cardiovascular fitness by American College of Sports Medicine (ACSM). Results There were no significant differences of all indexes within groups between Test1 and Test2 (all P>0.05) and correlation coefficients were higher than 0.9, suggesting high test-retest reliability. The pace was lowered (all P<0.01), HR was higher (all P<0.01), %HRmax was higher (all P<0.01) and there was no significant difference of RPE (P>0.05) in O group compared with NW group in Test1 and Test2. The relative exercise intensity in O group (72%HRmax) reached the threshold recommended by ACSM and criterion-related validation r=0.731 (P<0.01), but in NW group (59%HRmax) the threshold was lowered and criterion-related validation r=0.351 (P>0.05). Conclusion Exercise intensity of self-guided brisk walking is suitable for simple obesity patients but not for normal weight individuals. RPE may be a valuable indicator for simple obesity patients to monitor exercise intensity of brisk walking.
