Objective:
This experiment aims to measure different changes in the body of an individual when he takes part in various physical exercises. Taking part in physical activity affects both blood pressure and heart rate of an individual. This process is called a negative feedback loop, and it is more essential to the body, and it helps maintain the homeostasis of a body. When the heart rate of an individual increase, it also led to a rise in blood pressure. Therefore, the blood pressure and heart rate will differ in all three individuals (Erps et al. 2017) . My expectation towards this experiment is to record different reactions of every individual when doing some physical exercises.
Materials:
Pens and paper are used for recording.
Small size automated manometers are used to measure blood pressure.
Three people to take part in different exercises.
Procedures of the experiment:
The experiment involves about eleven different steps as recorder below.
Step 1: The 3 Individuals should be given about 20 minutes to rest or do and exercise before the actual experiment.
Delegate your assignment to our experts and they will do the rest.
Step 2: The blood pressure and the heart beats for all the three individuals on their healthier state after their rest by using automated manometers.
Step 3: Record all the individual's results on the paper.
Step 4: Individuals should start the exercise by doing some jugging for about 5 minutes.
Step 5: During the exercise, measure the heartbeat and all three individuals' blood pressure.
Step 6: Note down the results of every individual.
Step 7: After 5 minutes of jogging, remeasure every individual's heartbeat, and pressure and record them down.
Step 8: After 5 minutes of jugging, start measuring the heartbeats and blood pressure of every individual continuously until they go to their normal state.
Step 9: Put down the individual results.
Step 10: Repeat all the procedures and repeat the exercises.
Step 11: Put down the results of all three individuals.
Observation :
My observation is that every individual recorded different reactions after exercises regardless of taking part in a similar activity. According to my records, the first individual felt some pain in his muscle because he might not be doing any physical exercise. This is because his muscles have been inactive state; hence it gets exhausted quickly. The second individual shows some red sport on her cheeks since she might be feeling hot. This indicates that she has been active compared to the first person her; she was not so exhausted after 5 minutes of jugging. As I was recording the third person's results, I realized he was very active compared to others. She enjoyed the 5 minutes of jugging because she has taken part in the gym.
Results :
Figure 1: The figure below shows the 1 st time BPM at rest, during the run, and after.
Figure 2: Shows the Blood Pressure at rest and during/after on the 1 st time.
| Subjects | Rest | During/Post |
| Individual 1 | 115/75 | Stronger Pressure |
| Individual 2 | 108/78 | Getting stronger |
| Individual 3 | 100/70 | Stronger Pressure |
Figure 3: It shows the 2 nd time BPM at rest, during the run and post (3 minutes after the run)
Discussion:
Part one:
In my experiment, I used two females and one male. The first individual had 28 years old and 65 kgs; the second was 23 years old, and 60 kgs, and the last individual had 19 years old and 55 kgs. Their health status was good, but they don't take part in the gym regularly. My experiment started by measuring the bpm and each individual's blood pressure before, during, and after the exercise. After recording this, the individuals start jugging, and while they are running, I measure their blood pressure and the bpm. After this process, they stop and measure the same process.
Part two:
As per the experiment's objective, the heart rate and the blood pressure are expected to rise during the exercise. I, therefore, support the goal after recording all the individuals. This is because, during training, the heart has to contract to pump extra oxygen to the muscles. Therefore, the heart rate increases as the strength increases. There is an increase in all individuals on blood pressure, and once the exercise is over, blood pressure will then be back to normal. Taking part in activity increases blood pressure. The three individuals had average blood pressure. The rise in systolic blood pressure is caused by the energy required to provide muscles with oxygen (Erps et al. 2017) .
Conclusion
To conclude on the hypothesis of the blood pressure and heart rate increase when doing physical exercise. According to the recorded information above, knowing physiological changes help athletes, physiologists, and people in their daily activities. The data can also teach the importance of doing exercise to improve their health by considering die, medication, and avoiding drugs such as cigarettes.
