The
experiments design included two sections. One section was the
survey responses, and the other was the ECG measurements. In this
experiment, the subjects were 18 college students. In the
experiment, the independent variable was the hours of exercise and
life style habits, and the dependent variable was the changes in
heartrate before and after exercise. In the survey section, the
survey questions asked about the subjects background information.
These background related questions includes: Gender, Age, and
medical conditions. Additionally, the questions asked about their
life styles and exercise habits. Example of these questions are:
The frequency of their exercise, the intensity of their exercise,
and the specific type of their exercise. The survey section of the
experiment was used to determine the independent variable of the
subjects, which was: The hours of exercise and life style habits.
Through these survey responses, the subjects were divided into two
groups. One group was defined as moderate, and the other group was
defined as casual. Subjects who does less than 2 hours of exercise
a week were considered casual, while subjects who does more than 2
hours a week were considered moderate. Another main factor that
determined the groups was the type of the exercises. Since this
experiment was focused on cardiac fitness, subjects

Furthermore,
the subjects percent difference in BPM was calculated. The percent
difference in BPM was calculated by subtracting subjects after
exercise BPM to their before exercise BPM and then dividing the
number by the subjects BPM before exercise. A two-tailed t-test
was used to yield the p-value. The p-value was used to determine
the significance of the results. If the p-value is less than 0.05,
than it is considered significant. If the p-value is more than
0.05, than the result of the experiment was not
