Investigation into the affect of exercise on Heart Rate.

Extracts from this document...


Investigation into the affect of exercise on Heart Rate Plan We aim to identify the affects that exercise has on your heart rate. We are going to conduct a series of experiments to hopefully proof that heart rate increases with exercise. However we must bare in mind that everyone's heart rate is different, there fore we will try to make an average hart rate. Method !. Record a person's resting heart rate 2.Make them run vigorously for a minute (shuttle Runs) 3. After a minute of running record their heart rate for a minute 4.allow them to rest until their heart rate has returned to their resting heart rate 5.Continue this process, increasing the amount of time, by 30 seconds each time.(30 seconds, 60 seconds, 90seconds, 120seconds,150 seconds) 6. Repeat the whole process three times over, to create an accurate average reading. We have to know what there resting heart rate is so we can work out the difference in-between that and after exercise. ...read more.


* If they consume something to give them an energy boost(coffee, red bull e.t.c) * There will also be some human error, in the accuracy of timing-(reactions) and the amount that is run, whether it is turning corners, not quite running to the lines or over running * If they run out of Glucose * There heart cannot beat any faster so they get cramp and have to stop. Diagram Prediction I predict that the peoples heart rate will increase significantly from resting point (Doubled.)If you compile the results from each of the five experiments (leaving out resting time) and put them on the graph it should look like: The Gradient gradually increases for each extra minute, the amount this gradient t increases shows the persons fitness level. I predict this because I know that your heart beats faster when you are doing exercise because your muscles need the oxygen in your blood to create energy (aerobic respiration). If your heart can't beat fast enough you get energy from anaerobic exercise which creates lactic acid which gives you cramp. ...read more.


We could use a pulse monitor so if the pulse went really high (to fast for us to count) then the pulse monitor still would. It would also help if electronic strips for lines to run too so we can make certain the person has crossed each line. Instead of that we could use a tread mill where we could control distance, pace and the amount of effort put in. I think the test should have taken place on the same day not over a period of 3 days. This makes the second readings not compatible with the first, as the person could have been fitter or not felt as energetic, or tired in the morning but very awake and having just had dinner giving them more glucose. We could extend this experiment by doing longer periods of running (5, 10 minutes). Or concentrating on smaller times , under 30 seconds so we can see where the highest increase of heart rate is, this may not be possible though as it would be inacurate with only very small times.

    From here the cardio-acceleratory centre sends impulses to the sino-atrial node (SAN) via the sympathetic nerve to speed up the heart rate. The SAN is the pacemaker and is located in the wall of the right atrium. It determines the basic rate of heartbeat as a wave of excitation spreads out from it across both atria causing them to contract.
