Heart Rate Lab Report

Using the lab activity, observe and record the physiologic changes that occur during exercising using the following chart:

Once the thirty seconds was up, the person counting stopped and the heart rate (beats per second) was recorded. The same process was done again, but the counter counted the hearts beats for 1 minute. Again, after the 1-minute was up the heart rate was recorded for 1 minute. The same process was done again for 2 minutes, afterwards being recorded.

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.

Once the patient was correctly hooked up to the EKG the BIOPAC Student Lab Program was started. Lesson five is the one we used for this experiment and once it had been chosen we label it and started the experiment. There were four conditions we needed to measure; the first being lying down. The subject was lying down relaxing on the cot. We clicked record and let it run for 20 seconds. The data resembled the chart below. If it did not we would have had to repeat the steps until it did.

culture of slavery and is thus the most flagrant violator of the true Christian ideals that are expressed by Douglass. Again, it is necessary to go back to the idea stated earlier that the very existence of slavery tends to breed anti-Christian actions and thoughts (at least according to Douglass). The case of Covey points to the fact that this really is the case since he is an overseer and is thus more in the thick of slavery than some of the other characters. When discussing Covey, Douglass makes certain to point out how his version of Christianity versus that of Mr. Covey differs completely. For instance, Douglass’ ideals (and the antithesis of them) are expressed in the Appendix when Douglass states, “I love the pure, peaceable, and impartial

Throughout my life I have encountered many great leaders and they have all impacted me in their own way. One leader in particular led by example, respected everyone, and always wanted what was best for the team. This person was Taryn Barz.

* When the star jump exercise is complete I will then record the heart rate every minute using a stopwatch, until it returns to it's original resting pulse rate. Key Factors: In order to make my experiment a safe one we had to follow many obvious rules by making sure that the area we used was open and away from other people to avoid injury to others. We made sure that proper

Method and results - The study was compiled of seven female students from the University of Huddersfield. For the exercise a step was used, a polar heart rate monitor was used for each participant with an independent assessor timing the participants, and recording the readings. Results of the study showed there was an increase in heart rate when performing mild exercise.

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

Carry out an experiment to measure the heart rate and ventilation rate before, during and after moderate 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.

Press lightly until you feel a pulse (These instructions may also be demonstrated by the instructor for a visual aid), count the pulse for one minute using a watch or a clock with a second hand. The number you count is your heart rate. The normal heart rate for school age

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.

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).

In Book three C.S Lewis Starts off the chapter but stating that moral rules are not designed to stop happiness also he stated three significant parts of morality, first, fair play and happiness. Second finding happiness or harmony pertaining to each person. Third, the purpose of humans, questioning our purpose and out creator desire. Morality is related with our actions whether we define them as right or wrong. Morality many times is defined as guiding principles, without guiding principles a society will fail because it will be unorganized
