Investigating Pulse Rate In Relation To Exercise

Extracts from this document...


Investigating Pulse Rate In Relation To Exercise - During this piece of coursework, I am investigating links and patterns in relation to exercise. On Thursday 5th of June, I participated in various levels of physical performance at different intensities. To make sure it was a fair test, I carried out each activity three times. * Slow Walk * Brisk Walk * Slow Jog * Medium Pace Run * Sprint Here are my results - Time (m) Time (s) Speed Pulse Rate 1.29/1:56 89 80 0.58/0.60 58.84 120 0.46/0.47 46.65 150 0.33/0.35 33.12 152 0.29/0.26 29.21 186 The data represents my pulse rates immediately after each activity. ...read more.


The harder you work, the more oxygen your muscles need, obviously. Therefore, more oxygen must be pumped around your body, making your heart work faster. This increases your pulse rate. There are specific names for the intensity of your exercise. * Aerobic - long term exercise, for example, marathon running. Using a substance called glycogen, which your body converts from glucose found in carbohydrate food products such as pasta, it uses short energy amounts. In this investigation, it was used in the slow jog, among other activities. The formula for aerobic exercise is Oxygen + Glucose = Energy + C02 + H20. * Anaerobic - sprinting and short-term exercise that uses a lot of energy quickly. ...read more.


By training regularly, several things happen: * The volume of the heart increases * The heart walls get thicker. * Recovery rate increases. * Lower heart rate. * Volume of blood increases. * Your vital capacity increases. * Your intercostals muscles and diaphragm become stronger. * More alveoli are available for gaseous exchange. * More capillaries grow around the alveoli. So overall - Oxygen gets to the muscles quicker, and you get rid of carbon dioxide quicker. Conclusion - In conclusion, this piece of coursework has taught me a very strong link between exercise and pulse rate. As the intensity of your exercise increases, your pulse rate does too. Also, the level of fitness you have determines a lot about your pulse rate. By Al Horner, June 2003. GCSE Coursework - Biology. ...read more.

  2. How does exercise affect pulse rate?

    as it tends to be easier to find than the carotid pulse (above the carotid artery at the neck), we will count how many beats we feel for 30 seconds (this number will then get multiplied by 2 to work out the bpm).

The hormone also stimulates the production of glucose from amino acids. This hormone is mainly considered with the breaking down of glycogen to glucose

    This demand can only be met by the heart pumping faster (your heart rate increases to its 'working heart rate'). This results in more oxygenated blood being pumped to the working muscles. When exercise decreases, the working muscles require less oxygen.
