Heart Rate Investigation
The Effect of Exercise on 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, …show more content…
The first exercise will be walking, the following light logging and the last, hard running. I will perform these different types of exercises in a safe, open area such as a field. I predict that my heart rate will increase the faster and harder the exercise is. 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 …show more content…
I have concluded that as the amount of exercise undertaken by a person increases the faster
(higher) their heart rate will be. This is because when a person undertakes any movement or exercise they need oxygen to be taken in by the lungs and transferred to blood cells through the capillaries in the body and for the blood to transport the oxygen (and glucose) 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
