Hypothesis
Our heart rate will increase based on the exercise we perform.
Independent Variable
Type of exercise.
Dependent Variable
Beats per minute (BPM)
Experiment
For our experiment we decided to do three types of exercises: sit-ups, jumping jacks, and squats. Jumping jacks require a quick burst of a lot of energy. Sit ups are in the middle, requiring energy but not as rapid as jumping jacks. Squats are a slow exercise. For the first exercise we did sit-ups. His heart beat directly after averaged after the three trials, was around 90 BPM and the average recovery time was about 33 seconds. His baseline BPM while sitting was around 62 BPM. The next exercise was the jumping jacks. His baseline BPM was the same and his averaged heart rate was 109 BPM. His average recovery time was 35 seconds in a minute. Then we performed the final experiment, squats. These were statistically less demanding than the other based on the average BPM after the trials. The average was 88 BPM and the recovery time lasted around 32 seconds. The baseline BPM for this exercise was 64.
Conclusion
Our hypothesis that the heart rate of the test subject would increase while doing an exercise, and the higher the intensity, the higher BPM would be and the longer it would take to recover from the exercise. This was proven to be true that the heart rate was indeed affected by the type of workout. Other variables like health of person and environment are also in play but based on the tests, this hypothesis is correct. The squats, which are most likely the least demanding exercise of them all, based on the speed they are completed, and therefore the BPM and recovery time was less then the other exercises. The subject's BPM increased 24 units, with a quick recovery time averaged around 32 seconds. Nex
