Investigation into the effects of exercise on pulse rate

Investigation into the effects of exercise on pulse rate Investigation into the affects of exercise on pulse rate Background Respiration is the process of converting glucose into energy; it is not breathing in and out, as is often believed. Energy is needed for growth, repair, movement and other metabolic activities. The energy released from glucose in respiration is used to produce the chemical adenosine triposphate. Adenosine triposphate is where the energy released during respiration is stored for future use. Respiration happens in every cell in your body. There are two types of respiration; one is aerobic respiration. This is what happens when there is plenty of oxygen. Aerobic power depends on good lung function to supply oxygen to the blood, a strong heart to pump blood to the muscles and the muscles must be efficient in using the oxygen sent to them. The equation for aerobic respiration is: Glucose + Oxygen --> Carbon Dioxide + Water (+Energy) ...read more.


Pulse rate is caused by the actual impact of blood on the arteries. Method In this experiment I am hoping to prove that when using anaerobic respiration it takes longer to return to your resting heart rate than it does when using aerobic respiration. Apparatus I will need: Appropriate clothing Enough space to perform the activity A stopwatch What I am going to do: Firstly, I will record my resting heart rate. In the practical activity I will jog around the playground using aerobic respiration for three minutes. Straight after doing this activity I will take my pulse every 30 seconds until it returns back to its resting pulse rate and record the results in a table. Then I will do the exact same activity, except I will sprint for three minutes using anaerobic respiration. "I have decided to perform these experiments because they will provide me with a sufficient range and number of results to establish whether my prediction is true, and to identify relevant trends and patterns." ...read more.


78 bpm +230 seconds 78 bpm +240 seconds 72 bpm I have noticed that when I was using aerobic respiration it took 110 seconds to return to my resting pulse rate, whereas, when using anaerobic respiration it took 240 seconds. This is a 130 second difference. Graph to show my results: Conclusion: I have proved my prediction, "When using aerobic respiration, my pulse rate will return to its resting pulse rate quicker than when using anaerobic respiration." The reason for this is that when I used anaerobic respiration, I had a greater oxygen debt than when using aerobic respiration. My heart had to pump harder for longer to get the correct amount of oxygen back to the muscles. When I was sprinting I felt more tired, and my legs began to ache. This aching was the lactic acid building up, but as soon as I had repaid my oxygen debt it felt better. I was breathing more heavily, this was so I could get oxygen into my blood more quickly. ...read more.

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

    This energy is provided through a process called respirations. When the heart is at a resting rate oxygenated blood is being pumped around the body for a stable state of aerobic respirations. Resting rates vary between different people. The lower the heart rate of the person the healthier the person is.
