We studied determinants of the exercising physical capacity of 1,640 subjects (1,043 men and 597 women) using the Bruce protocol as modified by Sheffield. These participants represented a sample of parents of 17-year-old adolescents living in Jerusalem. Apparently healthy participants underwent a graded treadmill exercise test (88% of the men and 87% of the women). Exercise was terminated when the subject achieved a heart rate of 85 to 90% of the predicted maximal heart rate or could not continue for other reasons, mainly fatigue or weakness. Exercise performance was assessed according to time on the treadmill. On univariate analysis, duration of exercise was related in both sexes to age, country of origin, reported physical exercise, resting heart rate, systolic and diastolic blood pressure, body mass index and plasma lipids and lipoproteins. In multivariate analysis, time was related to age, body mass index, heart rate and habitual physical exercise in both men and women, and to systolic and diastolic blood pressure in men only. Cigarette smoking and plasma lipid levels were not independently related to time on the treadmill in either sex. Ethnic differences were observed.
我们采用谢菲尔德修改后的布鲁斯方案，对1640名受试者（1043名男性和597名女性）的运动体能决定因素进行了研究。这些参与者是居住在耶路撒冷的17岁青少年的父母样本。明显健康的参与者接受了分级跑步机运动测试（88%的男性和87%的女性）。当受试者达到预测最大心率的85%至90%或因其他原因（主要是疲劳或虚弱）无法继续时，运动终止。根据在跑步机上的时间评估运动表现。单变量分析显示，运动持续时间在两性中均与年龄、原籍国、报告的体育锻炼、静息心率、收缩压和舒张压、体重指数以及血浆脂质和脂蛋白有关。多变量分析表明，时间在男性和女性中均与年龄、体重指数、心率和习惯性体育锻炼有关，而仅在男性中与收缩压和舒张压有关。吸烟和血浆脂质水平在两性中均与在跑步机上的时间无独立相关性。观察到了种族差异。
