탈진운동 전·후 흡연시기에 따른 동맥경직도의 비교분석

Abstract

The present study is to identify comparative analysis on Arterial Stiffness by point of smoking before and after exhaustive exercise. Subjects were selected as male aduslt who smoke more than 10 cigarettes per da y for more than 3 years. Each group was composed of 11 subjectsh(rtee types of non-smoking, pre-exercise smoking and , all-time smoking) and they conducted Pre-exercise smoking and all-time smoking as well as progressive overload exercise to the all-out point. The results are as follow: 1) There was no interaction effect(p<.05) between each group and conducted exercise by those three types above but there was significant difference between poinot f time of smoking(before and after)(p<.05). For PSG and ASG, brachial-ankle pulse velocity was significantly decreased, after smoking, when compared to stable status. For all of the three group, brachial-ankle puls evelocity was significantly decreased when compared to other point of time immediately after exercises(p<.05). 2) There was no interaction effect(p<.05) between each group and conducted exercise by those three types above but exhaustive exercise made left and right ankle-rbachial index decreased significantly in all o f the three groups. There was no change of ankle-brachial index by point of time of smoking(p<.05). In general, our results suggest that smoking before exercise increases both left and right brachial-ankle pulse velocity and that the exhaustive exercise decreases bothle ft and right brachial-ankle pulse velocity and ankle-brachial index. There was also a limitation in identifying the effect of smoking as exercise made brachial-ankle pulse velocity lower than smoking when exercise and smoking were activated at the same time. Thus, further study should focus more on study on arterial stiffness after the exercise(which divides smokers into two groups of stop-smoking and continued-smoking) and on correlation between smoking and exercise by various age groups and different sexes.
