It is physiologically important to understand the arterial pulse waveform characteristics change during exercise and recovery. However, there is a lack of a comprehensive investigation. This study aimed to provide scientific evidence on the arterial pulse characteristics change during exercise and recovery. Sixty-five healthy subjects were studied. The exercise loads were gradually increased from 0 to 125 W for female subjects and to 150 W for male subjects. Radial pulses were digitally recorded during exercise and 4-min recovery. Four parameters were extracted from the raw arterial pulse waveform, including the pulse amplitude, width, pulse peak and dicrotic notch time. Five parameters were extracted from the normalized radial pulse waveform, including the pulse peak and dicrotic notch position, pulse Area, Area and Area separated by notch point. With increasing loads during exercise, the raw pulse amplitude increased significantly with decreased pulse period, reduced peak and notch time. From the normalized pulses, the pulse Area, pulse Area and Area decreased, respectively, from 38 ± 4, 61 ± 5 and 23 ± 5 at rest to 34 ± 4, 52 ± 6 and 13 ± 5 at 150-W exercise load. During recovery, an opposite trend was observed. This study quantitatively demonstrated significant changes of radial pulse characteristics during different exercise loads and recovery phases.
了解运动及恢复过程中动脉脉搏波形特征的变化具有重要的生理学意义。然而，目前缺乏全面的研究。本研究旨在为运动及恢复过程中动脉脉搏特征的变化提供科学依据。对65名健康受试者进行了研究。女性受试者的运动负荷从0逐渐增加到125瓦，男性受试者则增加到150瓦。在运动过程及4分钟恢复期间，对桡动脉脉搏进行数字记录。从原始动脉脉搏波形中提取了四个参数，包括脉搏幅度、宽度、脉搏峰值和重搏切迹时间。从标准化桡动脉脉搏波形中提取了五个参数，包括脉搏峰值和重搏切迹位置、脉搏面积、面积以及由切迹点分隔的面积。随着运动负荷的增加，原始脉搏幅度显著增加，脉搏周期缩短，峰值和切迹时间减少。从标准化脉搏来看，脉搏面积、脉搏面积和面积分别从静息时的38±4、61±5和23±5降至150瓦运动负荷时的34±4、52±6和13±5。在恢复过程中，观察到相反的趋势。本研究定量证明了不同运动负荷和恢复阶段桡动脉脉搏特征的显著变化。
