The Effects of Short Burst Exercise on Heart Rate Physical exercise plays a large role in maintaining the homeostasis and health of an individual. The benefits of being active not only promotes a more stable and functional body, but also strengthens various organs, systems, and muscles. The heart, in particular, receives a great advantage from physical exercise.
The heart is a major muscle of the circulatory system. This organ pumps deoxygenated blood through the right atrium to the lungs (Doebel et al., 2016). Gas exchange in the lungs increases blood oxygen content, moving the oxygenated blood back into the left atrium of the heart and out to various tissues (Doebel et al., 2016). In the average human, the heart contracts approximately

In the experiment, 20 seconds of jumping jacks were used to represent “short-intense exercise” on the heart; whereas, 40 seconds of jumping jacks represented “long-intense exercise”. According to graph 1, there was a huge difference between the resting and post-exercise heart rates for both exercise intervals. The differences in heart rates are measured by subtracting the average post-exercise heart rate from the average resting heart rate for each participant. The graph indicates that each student experienced a greater change in amount of pulses per minute after 40 seconds compared of jumping jacks compared to 20 seconds. Similar to graph 1, graph 2 demonstrated that students overall felt more heartbeats at the end of 40 seconds of exercise compared to the brief 20 second interval. The 40 second pulse/minute trend line is slightly higher than the 20 second heart rate line; this implies that students felt the impact of jumping jacks on the heart after doing it for 40 continuous seconds. From the mean differences in Table 1, a statistical t-test was used to determine the difference between heart rate at 20 seconds of exercise (short duration) and 40 seconds of exercise (long…show more content…
Confounding factors, such as stress of the student, activeness of the student, weight/gender/height of the student, temperature of the room (cold muscles vs. warm muscles), and any medications the students take, may interfere with the results by making heart rate faster or slower than normal conditions. In addition, sources of error-- in the form of self-reported heart rate and timer issues-- may not accurately reflect the rate of the student’s heartbeat at the time the experiment was conducted. Students may count their pulse irregularly or have trouble finding the pulse directly after exercise; this could lead to inaccurate reports and inconsistent
