Abstract:
The goal of this experiment was to find out how smoking affected nonsmokers, light smokers, and heavy smokers heart rate during cardiovascular endurance. The participants will record their pulse rate before and after every minute for six minutes after the step test. As predicted, the heavy smokers had an increase in pulse rate that was twice as high as the light smokers and nonsmokers who had similar increases in their pulse rate after exercise. The independent variable is how much the subject smokes which is either non, light, or heavy smokers. The dependent variable is pulse rate; it changes depending on how much the person has smoked. The smokers would have a higher resting heart rate than nonsmokers, their heart would increase immediately after exercising than the nonsmokers, and it would take longer to return to their starting heart rate after exercising than the nonsmokers did. Introduction:

For this experiment, we had three experimental groups. These experimental groups consisted of nonsmokers, light smokers, and heavy smokers. The task they were given was to find out how smoking affected their heart rate during cardiovascular endurance. We predicted that smokers would have a higher resting heart rate than nonsmokers, their heart would increase immediately after exercising than the nonsmokers, and it would take longer to return to their starting heart rate after exercising than the nonsmokers did. The participants will record their heart rate before the experiment and every thirty seconds after the experiment until they reach their starting heart rate. The cardiovascular fitness of heavy smokers would be more different than the cardiovascular fitness of light smokers. Methods:

The materials used in this experiment included a set of stairs to do the fitness activity and a stopwatch to record the subject’s...
