How Exercise Affects Your Heart Rate
The heart rate of a human varies from 150 beats per minute in young
children, to about 60 in the aged. However, I am not interested in the
differing rates between the aged and young, I intend to investigate
whether doing exercise may alter the rate or ones heart rate
considerably.
Variables:
Things that we could change in the experiment that could change the
heart rate are:
* Type of exercise
* Speed of exercise
* Distance travelled during exercise
* Time for exercise
* The time I wait before I take my heart rate after an exercise
In my investigation the…
…independent variable is the type of exercise, speed of exercise and
time for exercise.
…the dependant variable is the number of heart beats in a minute
…the control variables are the time I wait before I take my heart rate
after an exercise and the distance travelled during exercise.
Independent
variables.
I will vary the type of exercise between walking, jogging and running
so I’m basically just going to be changing the speed and when speed is
changed the time taken to travel a certain distance naturally changes
as well.
Dependent
Variables.
I will count my heart beat straight after an exercise for one minute.
I will know when time has reached 1 minute because I will use an
electronic stopwatch.

If I were doing this experiment again I would have to look closely at
the method of exercise I used. I think that exercising on a piece of
equipment like a running machine would produce more accurate results
because I would be able to guarantee that the exercise remained
constant throughout this experiment.
Finally, an actual ‘pulse-meter’ might have helped the experiment to
be more accurate. This is simply strapped round the chest of the
exercise and it measures your current heart rate. I believe that this
would produce a more accurate heart rate.
If I were to extend my experiment I could try different exercises such
as star jumps and step ups at different paces to see if this has
similar results.
Cardiovascular Activity And How it Influences the body. Introduction: Cardiovascular fitness is a form of aerobic fitness (Neporent and Egan 1997). There are many different ways of evaluating the amount of oxygen used during cardiovascular fitness and one the methods involved is called VO2 Max. VO2 Max is the maximum amount of oxygen that the body can hold.
•Controlled variable- amount of time exercising and resting, number of trials, type of exercise, same type of clothespin , intensity of the exercise, and the age of test subjects
To make sure it is a fair test; the procedure is repeated a couple of
In this lab we try and figure out the effects of exercise on cellular respiration, and identify a role of carbon dioxide production, breathing rate, and heart rate in determining the rate of cellular respiration. To do this we made a Phenol Red solution and used a straw to blow into it with no exercise to see how long it would take for the color of the Phenol Red solution to change, after this we measured our heart, and breathing rate. Then we did these same steps again after 1 minute, then another 2 minutes of exercising (Note: This lab was incomplete). The problem of this lab is “ How will carbon exercising, and increased carbon dioxide production affect the color of the Phenol Red, our heart rate, and our breathing rate. I hypothesize that if we exercise then we will affect our cellular respiration, and cause the Phenol Red to change color in a faster rate, because when we exercise we breathe heavily resulting in a higher carbon dioxide production which will cause the Phenol Red to change at a faster rate.
First I will record the pulse rate of the subject after performing physical activity which will give me the subject’s pulse rate after physical activity without the effect on the energy drink. After which I will make the subject perform the same but with different volumes of energy drink
In addition, each of the test subjects had high resting heart rate. On average, resting heart rate should be approximately
In this lab, we experimented how the incline of a ramp affects the acceleration of the toy car. In this experiment, we sent a toy car down 3 different ramps at 3 different heights. All 3 of the ramps had the same length of about 3.065 meters to ensure accurate data. We had to record The number of Trials, time, final time, distance, final distance, velocity, final velocity, and acceleration. In our lab the Independent variable was the height of the ramp and the Dependent variable is the Acceleration of the car when going down the ramp. With the small ramp, the average time moving down the ramp was 3.58 seconds. Then the average acceleration for the small ramp was .26 m/ss. That was the slowest time and acceleration out of all 3 slopes. Up second
The main components of the human cardiovascular system include the heart and blood vessels. The heart beats in order to pump blood to the vessels which are responsible for circulating it to cell tissue throughout the body. During the homeostasis process, the circulatory system provides oxygen and nutrients to the cell while removing waste products from the tissue fluid such as carbon dioxide within the lungs. This process is required for cell function.
Introduction: In year 10, biology, we have been studying the heart: the functions of the heart, the parts of the heart (ventricle, atrium) and heart problems. Besides that we have been studying the heart rate of humans. We were asked to create an experiment to see what affects heart rate. We discovered that diet, stress, cholesterol level, excitement, mass, age, temperature and exercise affected the heart. Diet and exercise were the only 2 doable and so my partner and I chose exercise. We determined that as the intensity of an exercise increased so did the heart rate of the person performing it.
The heart is an extraordinary structure that is the base of all human life. However, it similar to the uncomplicated functions of water pumps. As the heart beats, blood is distributed throughout the body using a network of blood vessels. The functions of the heart can be kept in regular and healthy conditions through exercise. Exercise has an effect on the blood that is circulating through the body. That circulating blood makes the heart desire more oxygen, causing the heart rate to increase rapidly to keep up with activity demand.
In conclusion, my hypothesis was supported through the data produced by my experiment. I had two groups, subject A and B were my control group and subject C and D were my experimental group. Subject A and B did not drink the 8 ounces of Gold Peak Sweet Tea and only did the 2 minute jogging exercise. Meanwhile, my experimental group which was subjects C and D tested my independent variable which was the Gold Peak Sweet Tea by drinking 8 ounces of it and then waiting 5 minutes so the caffeine could enter and play its affects in the blood stream and central nervous system before jogging in place. When I tested myself (I was subject C) I realized that after drinking the tea my heart started to pound and when collecting my data realized that there was an increase of 4.33 bpm from drinking the tea compared to not.
The female subject’s average power was 106 kg-m/sec. The average power output male were classified as good and female subjects were classified as average according to the Magaria- Kalamen classification chart. The mean power output for the male subjects was higher than the female subjects. Males have more Type II or fast twitch fibers, which are better for fast and powerful movements like the power test or any quick pace activity. Females tend to have more Type I or slow twitch fibers which are better for endurance exercises, such as running or biking. The first time running up the stairs was the slowest time for most of the subjects. This was probably because the subjects’ had to adapt to the task. The second trial was the fastest because the subjects’ were familiar with the task. The third trial for most of the subjects was slower than the second trial but faster than the first trial, most likely due to being tired. An error that could have occurred was the reaction time of the timer. The timer started timing when they saw the subject’s foot hit the first step. However, the time was not as accurate as possible because there is a delayed response before the timer hits the start button and the foot touching the step at a fast speed. Another error was that the stairs were not the standard set for the test. The vertical distance of the stairs is supposed to be 1.8 meters, but
body has to work harder I think that the heart will then increase at a

Investigating the Effect of Exercise on the Heart Rate Introduction For it's size the heart has the huge capacity of pumping large amounts of blood, in the average adult's heart beats 60 to 100 times a minute, pumps between 70ml and 100ml of blood with each beat, circulates 5 to 6 litres of blood around the body per minute and about 13 litres of blood per minute during vigorous exercise. The heart will beat more then 2.5 billion times during an average lifetime. This investigation will be looking at the effect of exercise on the heart rate. Aim The aim of this investigation is to find out how exercise affects the heart rate, using research & experimenting on changes and increases in the heart rate using exercise. Research â— The heart The normal heart is a strong, hardworking pump made of muscle tissue.
