# To examine the link between the rate of respiration and the amount of exercise done by exercising vigorously and recording pulse rate.

Extracts from this document...

Introduction

Respiration Coursework By Laura Hitchinson Aim: To examine the link between the rate of respiration and the amount of exercise done by exercising vigorously and recording pulse rate. Introduction: In order to function the body needs energy. Everything we do from sleeping to sport uses up energy. We create this energy through respiration. There are two types of respiration, anaerobic and aerobic. In aerobic respiration oxygen is used but in anaerobic respiration none is used. In this experiment we will be looking at aerobic respiration because the exercise is not very strenuous and anaerobic respiration won't be needed because anaerobic respiration only kicks in when aerobic respiration is not providing enough energy to keep the body going. ...read more.

Middle

This is then recorded. 2. The subject then does steps for 30 seconds. 3. The subject stops and pulse rate is measured and recorded. 4. The subject then relaxes for 2 minutes and their pulse rate is checked once again to see that it is back to normal. 5. When their pulse has returned to normal you then repeat steps 1, 2, 3 and 4. 6. Once you have done three sets of steps for 30 seconds, you then move the time up to one minute and repeat steps 1, 2, 3, 4 and 5 again. Increase the length of exercise by 30 seconds each time until 2 minutes 30 seconds Equipment: Stop watch Stairs/a step. ` Someone to measure the subjects pulse. ...read more.

Conclusion

Evaluation: I think the experiment went without any major problems. My method worked although I think we should of used a metronome in order to make sure the subject did the same exercise in all of the attempts because they may have done the step-ups slower or faster at some points which would of effected their pulse rate. This could be why the average pulse rate drops slightly in the last go. I think I could of changed the way we went about things by instead of timing the amount of exercise we did we could of done it so that we counted it by how many step-ups the subject did like 30 step-ups, 50 step-ups, 70 step-ups etc. ...read more.

This only occurs when an extended amount of exercise has taken place and in the first few minutes of exercise. During exercise, cell respiration in the muscles increases, so the level of carbon dioxide in the blood rises. Carbon dioxide is slightly acid; the brain detects the rising acidity in the blood.

of respiration was quickest and whether the rate of respiration gradually increased or decreased with time or whether the differences were just random. It will also help me see whether the amount of carbon dioxide followed a linear pattern or whether it was a curve.

The main reason that this source believed that adult stem cells were superior was because they avoided ethical issues. This book seems to place more emphasis on the ethical issues of embryonic stem cell research than the medical potential of them.

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

This is yet another method of doping the blood. When the artificial EPO is injected into the blood, it travels to the bone marrow just as the EPO from the kidneys would. The bone marrow cells interpret the chemical messenger the same way as the natural version and begin to produce red blood cells.

Inside the heart there are receptors, which are part of the nervous system these are connected to small systems called the cardio-acceleratory system and cardio-inhibitory centre. The cardio-acceleratory system responds to things picked up by the SA node in the heart, it is linked with the sympathetic nervous system and

There are some variables which I will not be able to control, and some which I will. For example, if I perform the first set wearing trainers and the second wearing school shoes the first set is likely to be a higher result because trainers are lighter and more comfortable than school shoes.

When exercise decreases, the working muscles require less oxygen. Your heart rate slows down, and the volume of oxygenated blood being pumped is reduced. When the exercise stops, the heart eventually returns to its 'resting rate'. The speed of this return to a 'resting rate' depends on the level of fitness of the performer.
