The purpose of this study was to compare the plasma catecholamine concentration at rest and in response to exercise in subjects with low and high trait anxiety (TA). Six subjects with low TA and six subjects with high TA were selected among 149 males college students on the basis of their results on three TA tests (STAI, IPAT, 16 PF). Plasma norepinephrine (NE) and epinephrine (E) concentrations (pg/ml) were measured at rest in supine position and during mild and moderate exercises of 5 min duration (about 40% and 60% of the individual VO2max) on bicycle ergometer. Plasma E concentrations at rest and exercise were not significantly different in subjects with low (33 +/- 6, 82 +/- 11, and 197 +/- 49) or high TA (41 +/- 7, 62 +/- 13, and 229 +/- 52). Plasma NE concentration was not significantly different at rest and in response to mild exercise in low (235 +/- 52; 666 +/- 64) and high-TA subjects (223 +/- 36; 610 +/- 88) but was significantly higher in high-TA than in low-TA subjects in response to moderate exercise (2510 +/- 618 vs. 1243 +/- 234). These results show 1) that plasma NE and E concentrations at rest and in response to light exercise are similar in low- and high-TA subjects, and 2) that subjects with high TA have a greater plasma NE response to the psychologic stress and/or to the homeostatic challenge of moderate exercise.
本研究旨在比较低特质焦虑（TA）和高特质焦虑受试者静息及运动时的血浆儿茶酚胺浓度。基于149名男性大学生在三项TA测试（状态-特质焦虑量表、艾森克人格问卷、卡特尔16种人格因素问卷）中的结果，选取了6名低TA受试者和6名高TA受试者。在仰卧位静息状态下以及在自行车测力计上进行5分钟轻度和中度运动（约为个体最大摄氧量的40%和60%）期间，测量血浆去甲肾上腺素（NE）和肾上腺素（E）浓度（pg/ml）。低TA（33±6、82±11和197±49）或高TA（41±7、62±13和229±52）受试者静息和运动时的血浆E浓度无显著差异。低TA（235±52；666±64）和高TA受试者（223±36；610±88）静息和轻度运动时的血浆NE浓度无显著差异，但在中度运动时，高TA受试者的血浆NE浓度显著高于低TA受试者（2510±618对1243±234）。这些结果表明：1）低TA和高TA受试者静息及轻度运动时的血浆NE和E浓度相似；2）高TA受试者对心理应激和/或中度运动的内稳态挑战有更大的血浆NE反应。
