Objectives: The purpose of this study was to examine the effect of smoking on aerobic physical fitness among physical education major male university students participating in regular exercise.
Methods: A group of 42 healthy male students majoring physical education were divided into two groups: non-smokers (n=26, 20.61±2.78 yrs) and smokers (n=16, 21.25±2.29 yrs). Graded exercise testing for maximal oxygen consumption (VO₂max) was measured by Bruce protocol.
Results: VO₂max was not different between non-smokers and smokers, however, exercise duration time in non-smokers was more longer than smokers’. In non-smokers, ventilatory threshold (VT) time was delayed longer than smokers (p<0.01). %VT/VEmax was significantly different between non-smokers and smokers (p<0.01). Resting heart rate (p<0.01) and recovery heart rate at 80 seconds (p<0.01) in non-smokers were significantly lower than those of smokers. The decrease in heart rate recovery in non smokers was greater than in smokers at 40(p<0.05), 60(p<0.05) and 80(p<0.01) seconds.
Conclusions: These results suggest that smoking has negative effects on aerobic fitness of male university students in physical education major.
