The mean value of cardiovascular endurance in the non-smoking sample group was 1.0773, more significant than the mean value for the smoking sample group. This study concludes that there is a significant difference in the effect of Nicotine on cardiovascular endurance in the athlete category of FIK UNM students, where the cardiovascular endurance of students who do not smoke is better than the group of students who smoke even though they are both active athletes.
