'Does Exercise increase the heart rate and recovery pulse?'

Extracts from this document...


Lucy Gillett 'Does Exercise increase the heart rate and recovery pulse?' What am I trying to find out? In this investigation I am trying to find out if the increase of exercise, affects the heart rate and recovery rate. How will I carry out this investigation? 1. Firstly I will take my resting pulse for 1 minute, (which I shall take before every period of exercise that I do) 2. I will then run between 2 posts 20 metres apart for an amount of time. (either 30secs, 1min, 2mins, 3mins, 4mins) 3. Once I have carried out the period of exercise I will take my pulse for 1 minute to get my heart rate. 4. I will then take my pulse every minute after the exercise was completed, until my heart rate is back to its resting pulse. 5. I will then continue repeating this method until all the times have been carried out 3 times. 6. Once this has happened I will work out an average for each amount of exercise. What equipment do I need in order to carry out this investigation? 1. Stopwatch 2. Trainers How am I going to make this experiment a fair test? To get a fair test I will do the following things: 1. I will do each period of exercise 3 times, to get an average. 2. I will stick to the period of time that I have agreed to do. 3. ...read more.


What references did I use to write this plan? To get some information and background on exercise I used one book: PE to 16 Sally Fountain and Linda Gee MY RESULTS All of my results are taken down in Beats per Minute (BPM). Experiment ONE Period of exercise Resting Pulse Heart Rate Recovery Pulse 0 seconds 75 bpm 76 bpm 0 minutes - 75 bpm 30 seconds 76 bpm 150 bpm 1 minute - 77 bpm 1 minute 72 bpm 174 bpm 2 minutes - 73 bpm 2 minutes 78 bpm 180 bpm 4 minutes - 77 bpm 3 minutes 74 bpm 193 bpm 4 minutes - 73 bpm 4 minutes 72 bpm 206 bpm 5 minutes - 69 bpm Experiment TWO Period of exercise Resting Pulse Heart Rate Recovery Pulse 0 seconds 67 bpm 67 bpm 0 minutes - 67 bpm 30 seconds 69 bpm 156 bpm 1 minute - 74 bpm 1 minute 72 bpm 169 bpm 2 minutes - 71 bpm 2 minutes 75 bpm 183 bpm 3 minutes - 76 bpm 3 minutes 73 bpm 200 bpm 4 minutes - 73 bpm 4 minutes 74 bpm 205 bpm 5 minutes - 75 bpm Experiment THREE Period of exercise Resting Pulse Heart Rate Recovery Pulse 0 seconds 70 bpm 71 bpm 0 minutes - 70 bpm 30 seconds 71 bpm 153 bpm 1 minute - 69 bpm 1 minute 76 bpm 171 bpm 2 minutes - 74 bpm ...read more.


As my results showed the increase of heart rate when exercising, the longer you exercise for the higher your heart rate and also the longer you exercise for the longer your recovery pulse is. So is my data reliable? I think my data is very reliable, as I took down true results and didn't impose any false ones. It is also very useful information and you can learn a lot about the increase of heart rate when exercising. Was the investigation carried out accurately? I think my investigation was very accurate. My results show no odd patterns, which suggests accuracy. I took down my resting pulse before every exercise and had a break after I had taken my recovery pulse, just in case my heart rate was still high after the previous period of exercise. Were there any odd results and if so why do you think this was? I didn't have any odd results. How could this investigation be improved? To improve this investigation I think I would probably have gaps of 30 seconds between each period of exercise, because the rise in heart rate was very high, so a smaller rise would give me better results and also they would be better to get a conclusion from. So what is my final conclusion? I think that exercise does increase your heart rate. This is proven by my results and graphs. I also believe that the longer you exercise for the higher your heart rate and also the higher your recovery pulse will be. ...read more.
