An Investigation to show how Different Exercises Affect the Pulse Rate

Extracts from this document...

Introduction

Contents: Aim: 3 Prediction: 3 Apparatus: 4 Fair Test: 4 Method: 4 Result: 4 Conclusion: 5 Evaluation: 5 An Investigation to show how Different Exercises Affect the Pulse Rate Aim: The aim of this experiment is to find my pulse rate after I run up and down stairs for one and then for two minutes I also want to find out what happens to my pulse rate when I run up and down stairs for two minutes with a bag with two and then four books. Prediction: I predict that during exercise, my pulse rate will increase because blood is being pumped faster around my body. The energy is taken out of oxygen and sugar needed for my muscles to respire aerobically. ...read more.

Middle

This causes cramp. We must get rid of the lactic acid because it poisons our muscles. We carry on breathing faster and deeper after vigorous exercise. The extra oxygen breaks down the lactic acid. This extra oxygen is called oxygen dept; our oxygen dept builds up after we exercise hard. It must be gotten rid of straight away. Anaerobic respiration is another kind of breathing. An example of an anaerobic respirator is a sprinter. When running, a sprinter holds his/her breath to stop them from slowing down. After the race the sprinter needs 7 litres of oxygen to get rid of the lactic acid inside them. I also predict that non-smokers will be fitter than smokers because they do not any tar in their lungs making harder for them to breath. ...read more.

Conclusion

It also increased a lot more when I run for 2 minutes. This means that my prediction was correct and that blood and oxygen were being pumped faster around my body. Evaluation: I believe that my experiment was successful. I got the result that I was looking for. However, what I would most like to change is the fact that when doing the experiment, I did not make sure that my pulse rate was at its original rate. I just waited until I felt fit enough to continue. I believe that if I had checked the pulse rate to be sure that it was at its original rate the experiment would have been a fair test.

    So in effect, it could be the lower temperatures that caused differences in respiration rates rather than the change of respiratory substrates, as was expected. As a result, my readings and results would be inaccurate and inconsistent, which would reduce the reliability of the interpretation of these results, thus making the dependability of my conclusions less credible.

  1. How does strenuous exercise affect your pulse rate and breathing?

    Most people's heart takes a while to recover because the muscles have respiring anaerobic -ally. The glucose was broken down to give energy with out oxygen it is lactic acid. Lactic acid is poisonous and it makes your muscles ache, it can also give you a stitch.

  2. How does exercise affect pulse rate?

    we will do the exercise for, and they will alert the group when there is 30 seconds left so that everybody has time to find their pulse (this makes counting easier and more accurate). We will take the radial pulse (above the radial artery at the wrist)

    the result will be next however for my preliminary graph, I cannot, which means that the experiment was not accurate. Evaluation of Preliminary Method I will start another method, as my preliminary method was not adequate for my investigation. My preliminary experiment had many problems of which I created by myself.

  2. Effects of Exercise on Blood Sugar Level and Pulse Rate.

    This is achieved by increasing the number of breaths per minute from an average of 15 at rest to 45 at the peak of strenuous exercise. With fitness training , the normally passive and relatively slow process of expiration is accelerated because both the internal intercoastal muscles and abdominal muscles

    I wanted to see if there was the same kind of variation between the results also in 0.8%. We didn't manage to do 0.6% but we did do 0.8%. Here are the results: As you can see here there is quite a variation in these results as well.

  2. The aim of conducting this experiment is to know the effect of exercise on ...

    Exercise can effect respiration and the heart rate dramatically too. Muscles need energy to maintain their functions. This energy is provided through a process called Respiration. When the heart is at resting rate oxygenated blood is being pumped around the body for a stable state of aerobic respiration.
