Action potential, Blood, Cardiology 811 Words 3 Pages Cardiovascular System: The Heart Laszlo Vass, Ed. My data is unreliable, because our common sense knows that the heart rate for sprinting should be more than jogging and walking. However, on the day of the experiment, one of the members in the group was absent due to sickness so the role of being test subject had to changed to someone else. In this investigation, you will examine how much your heart rate will increase and the amount of time it takes for your heart. After exercising for 1 minute on the stepper, results showed there was no difference in the heart rate of both contestants. The physiology of circulation is well documented and any pulse rate investigation should draw on the vast reservoir of knowledge online. Multiply each count by 6 to get the heart rate per minute.
The more energy a person is using during exercise, the more the cardiac output increases. Control variable 3: Still another variable that will be kept the same is the amount of time to do each activity. The family medical history indicated a history of heart disease on the paternal and maternal side of the family. It is worth studying these areas since they are fairly common among students who are coming to experimental science for the first time. It would be interesting to measure the heart and breathing rate on a smoker or a person that has certain health problems as eg.
View Lab Report - Assignment 4 Effect of Exercise on Heart Rate Lab Report Final Ashley Sotoodeh. Dependent variable: The variable that will be measured is the heart rate. Artery, Blood, Blood pressure 1993 Words 7 Pages Determination of a Rate Law Megan Gilleland 10. If this experiment was to be repeated, I would make sure that there is someone to assist me, means that the results will be more accurate. What was the dependent variable? We predicted that heart rate would increase with exercise. Aim: To find out if there is any relevant link between the amounts of exercise taken to increase a person heart rate. Conclusion The predictions that were previously made are supposed by the data.
Using the tally counter the heartbeat of the Daphnia is counted for 30 seconds. Another issue we faced was that the pace of an individual also affects pulse. The waste products are water, carbon dioxide and heat. Exercise, adrenaline in the blood, and a low blood pH are all stimuli that increase the heart rate. Or quite the opposite and being in a very relaxed state. Furthermore, the equipment used in the experiment will show the functions in the right and left arm; as well as, in the right and left ankles.
There are many reasons why your heart rate increases when you exercise, the most important one being that your. Hypothesis: I think that the heart and breathing rate will increase during activity. It will be directly proportional to each other, meaning that the increase of the concentration of the caffeine will give an increase of the heartbeat. The results should be stated but not discussed extensively, e. Therefore with more demanding exercises eg. At each rest, the subject will be recorded upon. They were used because this species of water fleas has a transparent exterior and it is easier to observe the heart rate of the Daphnia through the microscope.
Aim: The aim of this experiment is to find out how different intensities of exercise effect the heart rate I will measure it in beats per minute using a polar heart rate monitor. Homeostasis is the maintaining of a balanced condition in the body despite changing external conditions or demands on the body. We also had enough time to allow the individual to get their pulse back to normal. Step 3: This is repeated again for the 2nd time. Hypothesis: We believe that the male would have a lower heart rate after running up the stairs determining that he is in better shape.
Multiply the number by 6 to get the number of beats per minute. The persons was probably not relaxed. Risk assessment Prevention Caffeine Concentrations in eyes or spillages onto clothes. Students commonly test the effects of chemical agents on the heart rate of the crustacean Daphnia magna, but the procedure has never been. The heart rate is the amount of times it contracts beats in a unit of time, nearly always per minute. Write down the data 3. In this lab the participant was to execute an exercise to determine if homeostasis would maintain an stable heart beat and breathing rate.
This clearly shows that the time given, which was 2 minutes, was not enough, however due to our time constraint we did not allocate more time. Take time to write an answer to this question in the Lab Report section. It is used as a stimulant to human the central nervous system by increasing the stimulatory of the neurotransmitters, however high levels of caffeine to the body can cause effects of insomnia, stress, anxiety, weight loos or high blood pressure. However, your instructor has the final say in determining how your report. Nicotine, caffeine, and atropine would result in increased heart rates. Have your lab partner time 10 seconds for you as you count heartbeats.
Writing up your lab report can be found in your Lab manual Lab 23-pg 4-5. Artery, Blood, Circulatory system 1441 Words 5 Pages Discussion Heart Rate Our hypothesis stated 1. Adenosine triphosphate, Carbon dioxide, Cardiology 1663 Words 5 Pages Aerobic Exercise on Heart Rate Introduction: Our bodies need to be in balance in order to function properly, and there are many ways the body maintains balance, or homeostasis. This report discloses the basic laboratory instruments will be used in each of our practices. A Daphnia is a tiny crustacean related to shrimp that has a clear outside skeleton carapace and.
For this experiment we wanted to know how long participant can keep their feet in the bucket of ice water before they experience any pain while looking at neutral and positive pictures and also rate the intensity of their pain. We found that average pulse, mean arterial pressure. We would say that our Null Hypothesis was that the resting heart rate of. It also explains the reasons for why breathing and heart rate becomes higher during physical activity, and if there are any differences between female and males. In most people, the apex of the heart points to the left. This value is an important measure of articulators fitness, since people who return to resting heart rate faster have a more efficient heart and are at lower risk of cardiovascular disease and mortality. The heart rate may be too fast tachycardia or too slow bradycardia.
