研究人员从人口样本中招募了175名明显健康的中年男性，并让他们完成了关于习惯性体育活动、吸烟、饮料消费和睡眠习惯的问卷调查。在休息和次极限运动时测量身体质量指数（BMI）、心率和血压；在心电图节律条上测量室性早搏频率；测定了手握力和血清胆固醇。根据布鲁斯方案，这些特征与跑步机运动的持续时间相关。单变量分析表明，跑步机的表现与休闲时间的身体活动和个人报告的出汗和/或呼吸困难有显著的正相关。表现与年龄、BMI、静息心率、吸烟和含咖啡因饮料的消费呈负相关，但与工作体力活动、握力、饮酒、睡眠习惯、血压、抽雪茄、血清胆固醇和VPB频率的相关性不显著。其中11个变量与跑步机性能之间存在0.75的多重相关系数，并通过增加亚极限运动时的心率将r增加到0.81。通过问卷调查和容易获得的、无创的物理测量，可以对人群的工作能力和体质进行实质性的预测[冠心病风险的可能预测因素]。
Apparently healthy middle-aged men (175) were recruited from a population sample and completed questionnaires about habitual physical activity, smoking, beverage consumption and sleep habits. Body mass index (BMI), heart rate and blood pressure were measured at rest and during submaximal exercise; frequency of ventricular premature beats (VPB) were measured on an ECG rhythm strip; and hand grip strength and serum cholesterol were measured. These characteristics were correlated with duration of treadmill exercise by the Bruce protocol. Univariate analysis indicated that treadmill performance was significantly and positvely correlated with leisure-time physical activity and personal reports of sweating and/or dyspnea occurring regularly during such physical activity. Performance was negatively correlated with age, BMI, resting heart rate, cigarette smoking and consumption of caffeine-containing beverages, but was insignificantly related to job physical activity, hand grip strength, alcohol consumption, sleep habits, blood pressure, cigar smoking, serum cholesterol and the frequency of VPB. A 0.75 multiple correlation coefficient was found between treadmill performance and 11 of the above variables and the r is increased to 0.81 by adding heart rate during submaximal exercise. Substantial prediction of work capacity and physical fitness of population [possible predictors of coronary disease risk] is achieved by questionnaires and easily obtained, noninvasive physical measures.
