Peak Pre-Post Exercise Changes.

HR, heart rate (beats per minute); PP, pulse pressure (mmHg); MAP, mean arterial pressure (mmHg); cfPWV, carotid-femoral pulse wave velocity (m/s); AIx75, augmentation index adjusted to heart rate of 75 beats per minute (%); SEVR, subendocardial viability ratio (%).All values are mean±standard deviation.*PHR, cfPWV, AIx75, and SEVR are adjusted for age, exercise time, resting MAP, and the corresponding resting parameter between non-smokers and the two smoking groups (1 vs. 2 and 1 vs. 3). Repeated measures between Chronic and Acute smoking groups are adjusted for exercise time and resting MAP (2 vs. 3).Aortic PP and MAP were adjusted for age, exercise time, and the corresponding resting parameter. Post-exercise, these variables were adjusted for age, exercise time, and the corresponding resting parameter between non-smokers and the two smoking groups. Repeated measures between Chronic and Acute smoking groups are adjusted for exercise time and resting MAP.心率（heart rate, HR），单位为次/分钟；脉压（pulse pressure, PP），单位为毫米汞柱（mmHg）；平均动脉压（mean arterial pressure, MAP），单位为毫米汞柱（mmHg）；颈股脉搏波速度（carotid-femoral pulse wave velocity, cfPWV），单位为米每秒（m/s）；校正至75次/分钟心率的增强指数（augmentation index adjusted to a heart rate of 75 beats per minute, AIx75），单位为百分比（%）；心内膜下活力比（subendocardial viability ratio, SEVR），单位为百分比（%）。所有数值均以均值±标准差形式呈现。 *峰值心率（PHR）、颈股脉搏波速度（cfPWV）、校正至75次/分钟心率的增强指数（AIx75）以及心内膜下活力比（SEVR）已针对年龄、运动时长、静息平均动脉压，以及非吸烟者与两个吸烟组（组1与组2、组1与组3）间的对应静息参数进行校正。慢性吸烟组与急性吸烟组间的重复测量数据已针对运动时长与静息平均动脉压进行校正（组2与组3）。 主动脉脉压（PP）与平均动脉压（MAP）已针对年龄、运动时长及对应静息参数完成校正。 运动后，上述变量已针对年龄、运动时长以及非吸烟者与两个吸烟组间的对应静息参数进行校正。 慢性吸烟组与急性吸烟组间的重复测量数据已针对运动时长与静息平均动脉压进行校正。
