How Does Exercise Affect My Heart Rate?

Extracts from this document...

Introduction

How Does Exercise Affect My Heart Rate? The aim of this investigation is to find out how different types of exercise can affect my heart rate. To measure and record my heart rate, I am going to undergo an experimental test. I am going to do 3 different types of exercise: walking, light jog and lastly hard running. First, I will draw out a table to record my results, and then I will measure my resting heart rate for one minute. To make the experiment as accurate as possible, I will take and record each exercise, including my resting heart rate, 3 times to increase precision and to make sure each recording is exact. Initially, I am going to measure my resting heart rate 3 times for one minute. Each time I get my reading, I will record it into the table. My first exercise that I will carry out is going to be walking. I am going to walk for exactly one minute, and after that minute, I will measure and record my heart rate 3 times, also for one minute. I will rest for 5 minutes after each exercise in order to get my heart rate back to its resting pace. ...read more.

This is because exercise or other increases in physical activity require muscles to work harder or faster. To perform, our muscles consume oxygen. As our muscles work harder or faster, they require more oxygen. This increased demand for oxygen causes changes in the circulatory and respiratory systems. Our respiration or breathing rate increases: we take more breaths per minute in order to get more oxygen into the body. Our heart rate increases: the heart beats more times per minute in order to pump the blood containing the oxygen to the muscles. As a result, the muscles receive more oxygen per minute. Our heart rate and respiration rate stay elevated as long as the muscles continue to need more oxygen. When we stop exercising, the heart rate and respiration rate gradually decrease because the muscles no longer need as much oxygen. Therefore I predict my resting heart rate will be the lowest, and then the walking, light jogging and my hard running heart rate will be the highest. The measurements that I will use will be in seconds (s) and beats per minute (bpm) e.g. whilst running for 60s my heart rate was 180bpm. ...read more.

Conclusion

to all the body cells by being pumped around by the heart, so that they can use these two things in respiration (a reaction that takes place in every cell in the body) to produce water, carbon dioxide and most importantly energy so that the body muscles can do the necessary movement to do the exercise. When the exercise time is increased the need for oxygen to the muscles increases so that more respiration can take place to produce more energy for the muscles to work harder and for longer. For this to happen first the breathing rate increases. I think that my investigation was successful and I feel that the results I got were reliable and accurate. I think that my results are quite accurate. This is because I used a stopwatch/clock to accurately measure all the times. I haven't got any results which look erroneous or wrong. What I would do if I redid the experiment to increase the accuracy even more would be to use a device which measures my heart rate continuously. This apparatus would probably be more reliable opposed to if I manually measured and recorded my own heart rate, and it would probably improve the consistency and I would therefore get better results. Apart from that I would think my results are reliable and accurate as there are no anomalous results. ...read more.

    However, I believe that the best way to deal with all the problems surrounding the pulse and the method by which it was taken is to use a heart monitor instead. Now there is no need to find or even take a pulse, as the heart monitor would provide a value for heart rate before and immediately after exercise.

    We will then put our results into a graph (average of three people and both results) by working out the average amount of heart beats per minute for each person at the different exercise times and then averaging the three people's average results to get a more accurate graph.

    The stronger heart moves more blood with each beat and therefore can do the same amount of work with fewer beats. This means that in my experiment, someone with a higher BMI (of 30, for example) may have a lower resting heart rate than those with a lower BMI.
