# Investigation into the effect of exercise on Heart Rate.

Extracts from this document...

Introduction

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.

Conclusion

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 medullary neurons generate the rhythm for involuntary breathing sending impulses to the inspiratory muscles at a rate of 12-15 times per minute. During heavy exercise neurons that send impulses to the expiratory muscles become active but under normal breathing conditions they remain quiet, as expiration is passive at rest.

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.

The larger veins contain valves that maintain the direction of blood-flow. The flow of blood in veins is helped by contractions of the skeletal muscles, especially those in the arms and legs. When muscles contract they squeeze against the veins and help to force the blood back towards the heart.
