Effects of exercise on our heart rate.

Extracts from this document...


Effects of exercise on our heart rate I am trying to carry out an investigation where I can find out about the effects of exercise on our heart rate. I will have to do various experiments with different variables such as the amount of exercise, the intensity, or the environmental conditions to obtain valid results for my investigation. I will try the experiments on two males to see if there is a difference between two people. Prediction My prediction is that as the intensity or the length of the exercise increases the heart rate increases too, the need of oxygen in the muscle tissues due to the crave in the muscles to create the energy to keep going. I also predict that the heart rate will stay high after the exercise is finished due to the oxygen debt in the muscles and the need to recover from exercise. Preliminary work I am planning to do this experiment using different variables such as length of exercise and different types of exercise to see how each of them affect it. ...read more.

Finally, the CO2 levels also rose which also contributed to the heart rate rising. Evoluation My results where quite reliable as I used a heartbeat monitor to do the experiment which enabled me not to stop to take my pulse while I was doing the exercise. The evidence that I have collected during this experiment is enough to enable a firm conclusion to be drawn. This conclusion is as I had predicted that exercise increases your heart rate and also the intensity or the duration of the exercise clearly affect the increase in heart beats. A way in which I could improve my method would be by including other variables like the temperature or the place where the experiment has been done. Another thing that affects the accuracy of the experiment is that I couldn't know if I was performing at the same intensity during the whole experiment. I could make this factor disappear if I used a running machine so I could always run at the same intensity. ?? ?? ?? ?? Juan Mena ...read more.

    It is impossible to get identical people but if all these variations were as constant as possible, the experiment would be more reliable. This is because each of these factors affects heart rate and changes to it due to exercise.

Increasing pressure in the ventricles closes the triaspid and mitral valves; this then means that all four valves are closed.

    We will also make sure that a person's heart rate is back to normal before they undergo more exercise because otherwise the heart rate result will be affected and thus inaccurate. We will also keep things like the place, the conditions and the timer used the same to avoid any small errors in measurement.
