A Investigation to Show the Effects of Exercise on the Pulse Rate

Extracts from this document...

Introduction

A Investigation to Show the Effects of Exercise on the Pulse Rate Planning We have been asked to investigate the effects of exercise on the pulse rate. The are a few variables that could affect the results; the mass of the person exercising, the duration of the exercise, the age of the person exercising, how long we leave for the pulse rate to go back to rest, weather its aerobic respiration or anaerobic respiration and their diet. If you have an older person doing the exercise they tend not to be as fit and their pulse rate will increase lots and will take longer to go back down to rest pulse. If you exercise over along time it will take your pulse rate longer to return to normal and the longer you exercise, the higher your pulse rate goes. ...read more.

I predict that the longer I exercise for the faster my pulse will go and there will be a point when it will not be able to go any faster. Method To perform this investigation I will need a person willing to do exercise and a stopwatch. I will first take my resting pulse and then do the required amount of exercise (step ups) and then take my pulse for 30seconds and then double it. To take my pulse will use my index finger (not the thumb because that has its own pulse) on my neck. A Investigation to Show the Effects of Exercise on the Pulse Rate Results. Rest Pulse: 71bpm Duration of exercise in seconds Increase in pulse rate (beats per minute) ...read more.

Conclusion

So your heart pumps oxygenated blood round your body to your muscles and organs. Your muscles and organs then produce energy from the glucose and oxygen that's in the blood. The more you exercise the more energy you need so your heart beats faster increasing the pulse increases so that more blood can be pumped to muscles and organs. My results were fairly close to what I had predicted but I would have liked to find out when my heart cannot go any faster Evaluation My results were not very accurate but they show a pattern. I would have liked to make my results more accurate by using a treadmill and a pulse meter. I had one slightly odd result and I should have repeated the results for 90seconds.I would to do an experiment on anaerobic respiration to see how that effects the pulse rate when running the 100 hundred meters. ...read more.

Response to the question

The response to the question is okay. The candidate makes attempts to relate their observations to scientific facts, but the explanations are not done to the highest standard. The candidate also tried to carry out a valid experiment, but does not take into account confounding factors and does not take into account things that may have gone wrong in the experiment.

Level of analysis

The candidate does not make it clear why the different factors may affect respiration, and it is not clear to me how anaerobic and aerobic respiration will affect the pulse rate differently. The candidate does not explain their investigation very well, such as how they are going to make sure that the different factors will not affect their experiment or why the think that there is a certain point when the pulse rate will stop rising. The graph and results pattern explained is good, but the decimal places in the results table lacks consistency. The evaluation suggests some improvements but does not really examine what may have gone wrong with the experiment.

Quality of writing

Spelling, grammar and punctuation are fine, but the candidate should make better use of commas to communicate clearly and there are minor grammatical errors in places. The layout of the text is good as it is clearly presented in subheadings and paragraphed.

    Phagocytes - they move up to the bacteria and attach themselves with specific hooks like antibodies. Then they engulf the bacteria and release an enzyme called pseudopodia which digests the bacteria and absorbs the products. Lymphocytes - there are B and T lymphocytes.

    This allows blood to flow into the arteries. This is how the SAN controls heart rate. But if the heart rate had to be slowed down, receptors would send impulses to the cardiac inhibitory centre, which would send impulses to the SAN via the vagus nerve to slow down heart rate.
