Investigation into the effect of exercise on Heart Rate.

Extracts from this document...


Investigation into the effect of exercise on Heart Rate. What do we mean by Heart Rate Heart Rate is the amount times your heart beats per minute. You can find heart Rate by taking your Pulse. Aim By doing this experiment I am trying to find out how your heart rate is effected by the amount of exercise you do. What Variable am I going to Use? I will use step-ups for a certain amount of time, timing for 1minute then taking my pulse 2minutes then taking my pulse and so on. This will show how the amount of exercise effects your heart rate. Hypothesis I predict that the more exercise that I do the faster my heart pump giving me a faster heart Rate. As I do more exercise my heart rate will increase this is because as more movement is present more energy will be needed and respiration is generated faster so takes place at a faster rate. ...read more.


The glucose is either supplied from the blood stream or from its stored form glycogen in the muscles. This is called Anaerobic Respiration (without oxygen). The amount of oxygen needed to dispose of the Latic acid is called the oxygen debt, which must be paid off immediately. This is why even after you have stopped running your heart rate stays higher than usual as oxygen is still being delivered to your muscles. Method Equipment * Stopclock * A Step * Trainers * Results Table. 1. Get a Stopclock and go outside to a step 2. Take your Pulse 3. Record it in you results table 4. Start the Stopclock and begin jogging up and down the steps for 1minute 5. Take you pulse again for 1minute 6. Record it in you results Table 7. ...read more.


As you can see all my first four results fitted a clear pattern. They all slowly ascend. Conclusion My main findings were that the more exercise that you do the more your pulse increases giving you a faster heart rate. Evaluation Most my results fitted a clear pattern all ascending slowly from 76 to 134 beat per minute. By looking at my graph it looked like there was one anomalie, number 4. As you can see it rose higher than the one after it which it shouldn't have as the one after it was when you did step-ups for 5 minutes. So you heart rate should be lower on 4 than 5. The anomalie may have been cause because the jogger didn't wait for there heart rate to return to normal before starting the 4 minute jog. In order to improve the experiment I think we should of done it twice. So then we could have found the average heart rate making the results better and more reliable. ...read more.

    The Effects of Exercise on the Heart Rate

    4 star(s)

    The equipment used must be the same. If we were to change the bench to a step, the step may be higher or lower. Making the muscles work harder or lesser to step up. The heart would then have to work faster or slower in order to supply the required amount of oxygen to the muscles.

    Another way to overcome this would be to use a greater concentration of respiratory substrate (e.g. use 5% substrate concentration as opposed to 2% concentration). This would ensure that there would be excess substrate present which would allow the reaction to reach its maximum speed.

    to breathe more deeply when they take exercise; unfit people tend to breathe more quickly, keeping their breathing shallow. Looking at my graphs you can see that the person, which carried out the experiment, was reasonably feet as you can see the breathing rate only increased considerably and then they began to breathe at a constant rate.

    This is because there are some variables that I will not be able to keep the same, these are things such as how hard I press on the artery or the accuracy of my counting, and when I start counting.

  1. Potato and Osmosis Investigation

    One reason was that I did not leave the experiment long enough to actually allow the procession of osmosis to go through. Also, I actually confused myself by not knowing which potato piece came out of which beaker. So relating to my preliminary experiment, I cannot say whether my prediction was correct or not as the preliminary results were hectic.

  2. The effect of exercise on gas

    This process occurs in two steps. Firstly the bicarbonate ions are removed on an antiport protein, with every ion of bicarbonate being exchanged for one ion of chloride. This is known as the chloride shift and the cell's membrane potential is not affected as both ions have the same charge and so maintain electrical neutrality.

    to start the reaction, but 4ATP and 2NADH were made, a net product of 2ATP and 2 NADH. Energy has been released from glucose now, which could be used for that run, or the boring lecture. The end product is pyruvate, but pyruvate is not very stable in our cells.

    each of the values to produce an accurate, average value which would then be used to draw a graph upon. I believe the methods that I have chosen will be the most effective when conducting my experiment; this is because I have pre-planned the area and the variables which might affect the BMI (weight).
