The effects of psychological and physical stimuli on cardiovascular and catecholamine changes were studied before and after physical training. These functions were investigated in eight labile hypertensive men in response to the mild psychological stimulus of playing a video game and the mild physical stimuli of sitting and standing. The results show that plasma norepinephrine concentration rises with sitting and standing but plasma epinephrine concentration increases only with the psychological stimulus. Physical training was associated with smaller increases in blood pressure during psychological and physical stimuli and with a lower heart rate at rest. On the other hand, plasma catecholamines at rest as well as in response to the different stimuli were unchanged following moderate training. These observations suggest that the adrenal medulla is selectively activated during a period of mild psychological stress, while the activity of the sympathetic fibers is preferentially increased during mild physical stimuli. Furthermore, the results of this study show that plasma catecholamine levels at rest and their increase during various stimuli are unchanged following training.
在体育锻炼前后，研究了心理和身体刺激对心血管及儿茶酚胺变化的影响。对八名不稳定型高血压男性进行了这些功能的研究，以观察他们对玩电子游戏这种轻度心理刺激以及坐立这种轻度身体刺激的反应。结果显示，去甲肾上腺素血浆浓度随坐立而升高，但肾上腺素血浆浓度仅在心理刺激时增加。体育锻炼与心理和身体刺激期间血压升高幅度较小以及静息心率较低有关。另一方面，适度锻炼后，静息时以及对不同刺激做出反应时的血浆儿茶酚胺水平没有变化。这些观察结果表明，在轻度心理应激期间肾上腺髓质被选择性激活，而在轻度身体刺激期间交感神经纤维的活动优先增加。此外，本研究结果表明，锻炼后静息时的血浆儿茶酚胺水平及其在各种刺激期间的增加幅度没有变化。
