This study was performed to investigate the acute effect of the submaximal aerobic exercise upon epinephrine and nor-epinephrine levels in chronic smokers and non-smoker. The study was carried out upon 10 regular (15> cigarettes/day) smoker untrained male along five years and 10 never smoker untrained male. Subjects performed an endurance exercise that continues 40 minutes at 70% maximal heart rate. There were 15cc venous blood samples extracted from the forearm pre-exercise (PRE), post-exercise (POST), post-exercise 2 hours (2h), post-exercise 24 hours (24h) to measure of epinephrine and nor-epinephrine levels. The plasma level of each hormone increased after exercise and the tendency of rise was similar between groups as it seen in which 55,6% and 54,68% for epinephrine and 27,1% and 35,7% for norepinephrine. In this respect no group-time relationship has been found (p>0,05). But in between-group analyses, basal and after exercise levels were different (p<0,05). The study revealed the fact that, smokers have higher plasma levels of epinephrine and norepinephrine before and after exercise. The results demonstrate that long-term smoking induces elevate baseline and post-aerobic submaximal exercise plasma epinephrine and nor-epinephrine levels. The sympatho-adrenal activity appears to be disrupt with long-term smoking which effect the glycolytic and fat metabolism during exercise.

长期吸烟会影响诱导的儿茶酚胺释放吗？

进行这项研究的目的是研究有氧运动对慢性吸烟者和非吸烟者肾上腺素和去甲肾上腺素水平的急性影响。该研究是在5年内对10名常规（15支香烟/天）吸烟者未经培训的男性和10名从未吸烟者未经培训的男性进行的。受试者进行了以40％最大心率持续40分钟的耐力运动。从前臂运动前（PRE），运动后（POST），运动后2小时（2h），运动后24小时（24h）抽取15cc静脉血样本以测量肾上腺素和去甲肾上腺素水平。运动后每种激素的血浆水平升高，各组之间的升高趋势相似，肾上腺素分别为55.5％和54.68％，去甲肾上腺素为27.1％和35.7％。在这方面，未发现组时关系（p> 0.05）。但是在组间分析中，基础水平和运动后水平不同（p <0.05）。研究表明，吸烟者运动前后血浆中的肾上腺素和去甲肾上腺素水平较高。结果表明，长期吸烟会导致基线和有氧运动后亚最大运动血浆肾上腺素和去甲肾上腺素水平升高。长期吸烟会破坏交感肾上腺的活动，这会影响运动中的糖酵解和脂肪代谢。结果表明，长期吸烟会导致基线和有氧运动后亚最大运动血浆肾上腺素和去甲肾上腺素水平升高。长期吸烟会破坏交感肾上腺的活动，这会影响运动中的糖酵解和脂肪代谢。结果表明，长期吸烟会导致基线和有氧运动后亚最大运动血浆肾上腺素和去甲肾上腺素水平升高。长期吸烟会破坏交感肾上腺的活动，这会影响运动中的糖酵解和脂肪代谢。
