Investigation Into The Effect Of Exercise On Pulse Rate

Extracts from this document...

Introduction

Investigation Into The Effect Of Exercise On Pulse Rate Aim Investigate the change in pulse rate after different durations of exercise. Fair Testing (variables) Independent variable: Duration of exercise Dependent variable: Change in pulse rate Controlled variables: -Type of exercise -Fitness of subject -Sex of subject -Mass of subject -Rate of exercise Predictions And Theory I think has the duration of exercise (independent variable) increases, the pulse rate (dependent variable) of the subject will increase considerably from the resting pulse rate. I think this because the body will need to deliver oxygen and glucose contained in the oxygenated blood more quickly. Apparatus * Stopwatch * Bench Method (Main Test) * Draw out a table to put your results in, it should have duration of exercise going down vertically and the measurement number and average going across the top horizontally, like this one: Pulse Rate (bpm) ...read more.

and keeping everything else constant (controlled variables). I kept the timing on the stopwatch as accurate has possible and did the step ups at a constant pace. Also, it was always my pulse rate that was measured keeping the subject the same. To get an accurate result has possible I repeated the experiment three times and then got an average of the 3 measurements that were taken. Safety * Step ups should be taken at a regular/constant pace to ensure you don't slip of the bench. * Shoes or trainers should be worn to protect feet. Observations I did find three results that seemed unusual, I think it was due to it been difficult to get an accurate pulse rate without using some type of electrical pulse rate measurer. ...read more.

Conclusion

However I think I could have made some changes to make the results more accurate, such has: * Using an electronic pulse rate monitor has it was sometimes heard to count the pulse rate especially after a long duration of exercise. This would also decrease the time between exercise. * Make sure I did the exercise at a steady rate. * Repeat the investigate after a long amount of time to ensure the body has gone down to its resting pulse rate. However, we did not get any results that seemed out of place. I think if we were to repeat the experiment again the results would not be exactly the same but if put on a graph the curve would be very similar. Mainly because of the inaccuracy of counting the pulse rate. I think if we could exercise for a longer duration we could prove that after a certain duration of exercise the pulse rate does level out. ...read more.

    In our experiment we should see a difference between the different periods of exercise, the pulse rate should go faster at the end, and also a difference between lying down and standing up. Rest Exercise Standing up 30s 73-74 20 steps 104 Lying down 30s 62-60 40 steps 106 80

    This evidence is gained from the graph shown above. The first intensity of exercise (30 step-ups) was the more intense of the two exercises completed. This is found because the pulse rates after the first exercise shown on the graph are higher than those at similar times after the second exercise was completed.

    When the amount of time was increased for the skipping, the pulse rates varied quite a lot. We expected that the pulse rate would increase more steadily than the results have shown, because although the highest rate was for 3 minutes of activity, it also showed one of the lowest rates of the experiment.

    Residual volume cannot however be measured using a spirometer. From the trace it can be identified that the tidal volume is almost double the textbook figure. This may be due to a number of reasons: this is the first result taken and the mouthpiece may have felt strange and so caused still stress making the individual breath more deeply.
