Effect of exercise on the heart rate.

Extracts from this document...

Introduction

Effect of exercise on the heart rate In the average human the heart rate slowly decreases through age. I am going to investigate that from doing exercise that the heart rate will increase. From the scientific knowledge that I have gained I know that for respiration to take place the body should respire more as through exercise the muscles require oxygen. The muscles obtain the oxygen from the blood stream and as they require an increase in oxygen as they work harder the pulse rate should therefore increase gradually as the body has to work harder. When exercise is complete the pulse rate and respiration should return to the normal "resting" rate as the muscles no longer need the extra oxygen as they are not working harder. ...read more.

Middle

If the body is unable to continue aerobic respiration anaerobic respiration will take place. This results in lactic acid being formed. I am going to run a 200m circuit around my garden. The heart rate will be taken by feeling the pulse on the neck. Here is the procedure of the experiment: - I will warm up by doing some stretches - The resting pulse will be taken and recorded - I will begin by walking the 200m circuit and then using a stopwatch I will count the number of times my heart beats in a minute. - I will do this three times so that I can take an average of my pulse rate so my recordings are more accurate. ...read more.

Conclusion

For instance, I cannot prove that the exercise I completed was at ther same rate and that I ran 200m exactly. If I were going to do this experiment again I would change the method of exercise I performed. I think that if I used professional running equpipment like a tread-mill I 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 me produce more accurate readings of my heart rate as sometimes throughout the experiment I didn't feel the pulse or I lost track. Here is my table of results and my graph of results below: pulse rate exercise trial 1st time 2nd time 3rd time average resting 64 64 64 64 walking 96 100 98 98 jogging 140 140 160 149 running 128 130 145 138 ...read more.

    When using Maltose as the respiratory substrate, I again noticed that the rate of respiration was faster during the second half of the experiment than the first half. This is probably due to the same reasons as described for Glucose (also see evaluation).

    This is recorded when the subject is standing and during moderate exercise. The subject will undertake 2 minutes of exercise before recordings to allow a period of equilibration.

  2. The effect of Exercise on Pulse rate

    Arteries have much thicker wall than veins. This is because the pressure in them is much greater as they come straight from the heart, and the blood is being pumped very fast. Arteries come from the heart; they collect oxygenated blood from the lungs and deliver it to other parts of the body.

    atmosphere is actually being used to help the cells in my muscles respire. Mitochondria are found in greater numbers in fast respiring cells such as muscles which are doing this when I exercise, this is because they are the site of aerobic respiration.

    That means that the amount of oxygen available to the working muscle can be increased by almost 15 times. As you exercise, the blood vessels in your muscles dilate and the blood flow is greater, just as more water flows through a fire hose than through a garden hose.
