장기적인 흡연이 젊은 성인남성의 유산소 운동능력에 미치는 영향 = The Effects of Chronic Smoking on Young Male Adults` Cardiorespiratory Function

다국어 초록 (Multilingual Abstract)

This study examined the effects of chronic smoking on young male adults` cardiorespiratory function. The examinees were composed of 199 young male adults of 20s who took medical investigation between January and December, 2005 at N Center. They were divided into two groups - smokers(106 people, smoking 19.8±6.9 cigarettes a day for 7.7±2.7 years); non-smokers - and took the measure of their body components, blood pressure, pulmonary capacity, VO2max, HRmax, and exercise duration time. The collected data were analyzed by one-away ANOVA and pearson correlations. The results were as follows. 1. There was no significant difference in Body components(BMI, WHR, %fat), pulmonary capacity(FVC, FEV1.0), rest heart rates and blood pressure(SBP, DBP) between two groups. 2. Maximal oxygen intakes(VO2max), maximal heart rates(HRmax) and exercise duration time of non-smokers were higher than those of smokers. However, there was no critical difference in threshold between two groups. 3. There were significant correlations between smoking duration and VO2max(r=-.160) and HRmax(r=-.231) and exercise duration time(r=-.205)(p<0.01). Also, there were important correlations between the number of cigarettes smokers smoke a day and VO2max(r=-.187), HRmax(r=-.281), and exercise duration time(r=-.275)(p<0.05). However, the results did not show significant correlations between smoking and the other variables. The results suggest that chronic smoking has negative effects on young male adults` cardiorespiratory function, whereas it has no effects on rest heart rate and blood pressure. It is necessary to study the relations between cardiorespiratory and additional behavioral and environmental factors such as smoking, drinking and lifestyle.
