本研究的目的是根据有氧运动中心纵向研究（德克萨斯州达拉斯）的数据，确定自我报告的历史步行、跑步和慢跑 (WRJ) 活动的结构相关有效性。 1976年至1985年间，共有4,100名男性和963名女性接受了至少一次体检，并于1986年完成了一份随访调查问卷。在体检时测量了血糖、胆固醇和甘油三酯水平、静息收缩压、体重指数（体重（kg）/身高（m）（2））和心肺健康状况。后续调查问卷评估了从 1976 年到 1985 年每年的 WRJ 和其他剧烈活动。数据分析包括 Spearman 和偏相关、方差分析、协方差分析和 t 检验。结果表明，在整个 10 年期间，每年回忆的 WRJ 和跑步机时间之间存在显着相关性 (r = 0.40-0.61)。历史上，参与者被分为两类：要么身体活动足够活跃，才能获得健康益处，要么活动不足，无法获得健康益处。参与足够水平的历史 WRJ 与男性和女性较高的跑步时间、较低的体重指数以及较低的男性甘油三酯水平相关。与测量的跑步机性能相比，自我报告的历史 WRJ 可以具有合理的有效性进行评估，并且过去长达 10 年的报告准确性不会下降。
The purpose of this study was to determine the construct-related validity of self-reported historical walking, running, and jogging (WRJ) activity on the basis of data from the Aerobics Center Longitudinal Study (Dallas, Texas). A total of 4,100 men and 963 women underwent at least one medical examination between 1976 and 1985 and completed a follow-up questionnaire in 1986. Levels of glucose, cholesterol, and triglycericles, resting systolic blood pressure, body mass index (weight (kg)/height (m)(2)), and cardiorespiratory fitness were measured at the time of the medical examination. The follow-up questionnaire assessed WRJ and other strenuous activities for each year from 1976 through 1985. Data analysis included Spearman and partial correlations, analysis of variance, analysis of covariance, and t tests. Results indicated significant correlations between recalled WRJ and treadmill times for each year throughout the 10-year period (r = 0.40-0.61). Participants were classified as historically either sufficiently physically active to receive a health benefit or insufficiently active for a health benefit. Engaging in sufficient levels of historical WRJ was associated with higher treadmill times and lower body mass indices for men and women and lower triglycericle levels for men. Self-reported historical WRJ can be assessed with reasonable validity in comparison with measured treadmill performance, with no decay in accuracy of reporting for up to 10 years in the past.
