What factors affect the pulse rate after exercise?

Coursework What factors affect the pulse rate after exercise? 15/11/01 Introduction: - As humans we need the heart to pump blood all around the body in order for us to live. We measure the rate of it, by measuring the pulse. We can measure pulse either on the inside of your wrist or the both sides of your neck. Pulse is taken in beats per minute usually, and depending on how much it is, we can take information on how fit and healthy you are. Pulse rates can vary from 60 up wards to about a 180 (this is the peak). In women the peak pulse rate is anything between 130-150, whereas in men the peak pulse rate is anything between 160-180 beats per minute. The factors that affect pulse rates are activity, fitness, age, and stress. The more beats your heart as beat out the more pressure you exert on your heart. ...read more.


and take the average. Prediction: -: I predict that the more prolonged my exercise becomes the longer it will take to get the pulse back to resting rate. I think in the duration of the exercise the pulse rate will increase and increase until it reaches a peak and then it will steady out. I also think that my fitness also is a major factor. This is because the body goes into a mode of anaerobic respiration. This is when the body begins to ventilate more (i.e.: breathe more) to accommodate the need of more oxygen in muscles, move the oxygen around your body faster and dispose the carbon dioxide. Also as you progress, lactic acid is produced. In order to break this acid down you need to breathe in oxygen, so it eventually breaks down into glucose and carbon dioxide. This process is called the "oxygen debt". The lactic acid that is produced is a mild poison that makes your muscles ache and cramp. ...read more.


This was due to the increased respiration happening within my body. Also athletes that specialise in running usually run in the mountains (the mountains have a higher altitude meaning less oxygen) increase the amount of haemoglobin in their body. This makes the intake of oxygen much easier. Method: The experiment in total took about fifteen minutes, ten minutes to prepare and five minutes to actually do the experiment. I set the stop-clock on my desk ready to press. I sat down on my bed and recorded my resting pulse rate for one minute. I recorded exactly 72 beats per minute. Making sure my clothes were ok, I started the stop-clock and jogged on the spot for one minute. I then stopped the clock at exactly one minute and took my pulse for a minute, after that I recorded how long it took for the pulse rate to revert back to my resting pulse rate. I repeated this process a further four times, and wrote the results down each time on my table of results. Diagram: ...read more.

    Repeating the experiment 10 times means that my results were not completely accurate and thus the reliability of my results and conclusions could be questioned. Most Statistical calculations should be used to analyse data if there are at least 30 repeats for each set of data.

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

    From my results I can make a conclusion is the pulse rate increases during the exercise. If you do exercise like walking it would not affect your pulse rate a lot but if you do jogging it would effect increase your pulse rate more.

  2. How does Exercise affect the pulse rate

    There are some other very important changes in the body that take place during exercise. The arteries divide into smaller vessels called arterioles. The arterioles have proportionally less elastic tissue and more muscle fibers then the arteries. The arterioles widen so that the blood pressure won't go to high.

  1. How does exercise affect the pulse rate?

    So the lactic acid has to be replaced and repaid with oxygen, this is known as the o2 debt. The oxygen is carried around in our red blood cells. The blood is pumped all around our body constantly. The haemoglobins in the red blood cells is what carries the oxygen in the blood.

  2. How does exercise affect the pulse rate?

    If the pulse rate is higher that means your heart is pumping very fast to get all energy and oxygen to its place. Here is a picture from which I have found on Encarta below- Blood Blood is a fluid that acts as a conveyor belt, which carries oxygen to all living cells in your body.

  1. How does exercise affect pulse rate?

    can get absorbed into the blood stream and carried to where it's needed. This is how respiration is linked to pulse rate. I predict that the more we exercise the faster our pulse rate will be, to a certain extent.

  2. To investigate factors which affect pulse rates when exercising.

    respiration is the release of a little bit of energy very quickly. This would happen when exercising for example. The equation for anaerobic respiration is: Glucose -> lactic acid + a little bit of energy Glucose is again brought to the respiring cells by the blood stream but because there
