Experiment to Determine How Heart Rate is Affected by Exercise

Introduction: In this experiment, cardiovascular fitness is being determined by measuring how long it takes for the test subjects' to return to their resting heart rate. Cardiovascular fitness is the ability to "transport and use oxygen while exercising" (Dale 2015). Cardiovascular fitness utilizes the "heart, lungs, muscles, and blood working together" while exercising (Dale 2015). It is also how well your body can last during moderate to high intensity cardio for long periods of time (Waehner 2016). The hypothesis is that people who exercise for three or more days will return to their resting heart rate much faster than people who only exercise for less than three days.

This experiment was carried out as noted about in Procedure 1. The resting heart rate was established and used as a baseline value from which to compare all future deviations. While data could

The authors then share their analysis on the changes of heart rate and GSR at the many different points throughout their study.

In the first experiment I was subject 2. For the most part my heart rate did not oscillate too much. My heart rate was a little slower than the other subjects as well. Compared to Activity 2, his oscillations while exercising were a little more dramatic. The reason for this could be that your heart is trying to adjust to the new physically taxing activity that you are enduring. Your body is trying to balance, but if it is thrown into a demanding activity it will take a little bit more adjusting than if you are just resting.

In this assignment I will be introducing a formal report that is based on an investigation into how the body responds to exercise and which analyses the results from the investigation. The investigation involves myself and other pupils in my class. I will be doing the Harvard step test. the other pupils in my class will be monitoring my heart rate, breathing rate and temperature before and after the test.

B. Part B. PowerPhys Experiment 4 – Effect of Exercise on Cardiac Output (13 points total)

The effects of heart rate on differing durations of exercise were studied in this experiment. For people, heart rate tends to increase as they perform physical exercises. The amount of beats per minute gradually increases as people perform physical activities. Heart rates taken before exercise are relatively low, and heart rates taken one minute after exercise increase significantly. Heart rates slowly begin to decrease after they are taken two minutes and three minutes after performing the step test, which is to be expected. The rates of intensity throughout exercise relates with changes in heart rate throughout the step test performed in the experiment (Karvonen 2012). The age of the participants affected the experiment, since the heart rate during physical exercise, in this case the step test, is affected by age (Tulppo 1998).

Being knowledgeable about the heart is very important, especially if one is an athlete. This experiment is significant, because it can tell us how important it is for one to keep their heart healthy. It will also tell us how playing a sport can benefit one’s health and the well being of their heart. Our hypothesis says, if the athleticism of a person increases, then the heart rate recovery time will decrease when heart rate recovery in a function of athleticism. The purpose of this project is to see which type of athlete, or non-athlete has the best heart function.

The controlled variable included the exercise bike and heart rate monitor. There are several limitations, systematic and random errors that should be considered when interpreting these results. (4) The controlled variables were not tested before this experiment to see if they were working and reliable. Figure 2 heart rate was quite inconsistent and did not follow the pattern of the other results, which maybe suggest a random error with the heat rate monitor. A systematic error could include the fitness of the participants. One of the test subjects is an endurance athlete and the other does not compete in any sport. This would affect the results because for the endurance-trained athlete, from their training they increase their cardiac output results from a substantial increase in maximal stroke volume. In untrained persons, cardiac output increases in response to exercise primarily by an increase in heart rate. The endurance-trained athlete does so mainly by an increase in stroke volume. Simply meaning that although both participants are doing the same cadence and length the endurance athletes skewers the results by already having an increased rate in stroke volume. Another systematic error may include the rate of perceived effort. For the most accurate results, the measured maximum heart rate would be necessary to give an accurate cadence to ride at.

Our experiment was performed in the Science and Technology build on the USCB Bluffton Campus on October 6th from 4:30 to 5:30 p.m. In order to construct the study for this experiment, we divided the actual experiment work in order to be able to complete the study for all sixteen (16) subjects within the given time period available to accommodate the test subjects. The experiments was conducted in the hallway, during the process we tested three participants at a time. We constructed an informational form regarding gender, age, weight amount of exercise per week. The supplies needed were approximately 25 test participants for the class, informational form, a blood pressure reader, timer, 15 jumping jacks, three chairs, paper and pencil to record

Research Question: What is the effect of practicing aerobic sports on a daily basis, on the recovery heart rate of people?

Aims - This study is to ascertain, if there is an effect on heart rate after exercise. This is being done to see, if there is a difference between resting heart rate and heart rate after performing exercise.

Oxygen is required by the cells to carry out respiration, this provides the energy in the form of adenosine-triphosphate (ATP) which is a molecule required for muscular contraction. As exercise takes place, oxygen is used

The literature on the effects of exercise of cardiac output maintains the idea that exercise should affect cardiac output- pulse rate, systolic blood pressure, diastolic blood pressure, QRS-pulse lag, P-T and T-P intervals, because of increased heart rate. For our experiment, we tested this theory by measuring our cardiac output before and after some rigorous exercise. We measured the individual cardiac output and then combined the data to compose a class-wide data average. We compared the results of the experiment to what we expected, which was that exercise does affect our heart. Our data from this experiment supported the notion that exercise does, in fact, change cardiac output.

Now that the experiment has been tested, the results are in there comes the analysis part of the process. After I had determined my calculation I saw where my beats per minute were over a hundred; this consider me to be Tachycardia. Tachycardia refers to an abnormally fast resting heart rate. When examining what Tachycardia was and how it can be affected made me see that different scenarios will affect the beats per minute. Anxiety, caffeine, stress can all cause someone to have such a rapid heartbeat. I remember from when taking the echocardiogram that I was stressed
