Are you healthy

  1. 1. Are You Healthy? 2010-12-10 Diane Guo<br />Pulse rateResting rate1 min2 min3 min4 min5 min74176128112112100<br />25400323215Diagram of my pulse rate against time<br />In this graph it shows my pulse rate against time. When its right after the exercise, my pulse rate was very high. After one minute, it calm down quickly, but then it calms down slowly. I did 2 graphs because the first one include the resting rate in it, second one does not include. <br />0146685<br />Pulse rates<br />Resting rate: a) 19 x 4=76 (bpm)<br /> b) 18 x 4=72 (bpm) <br />Average: (76+72)2=74 (bpm) <br />Right after the exercise: 44 x 4=176 (bpm)<br />1 minute: 32 x 4=128 (bpm)<br />2 minutes: 28 x 4=112 (bpm) <br />3 minutes: 28 x 4=112 (bpm)<br />4 minutes: 26 x 4=104 (bpm)<br />5 minutes: 25 x 4=100 (bpm)<br />Percentage of pulse rate<br />Right after the exercise= 176 bpm<br />Resting rate = 74 bpm<br /> Percentage= x 100% ≈237.84%<br />Rate after 1 minute= 128 bpm<br />Resting rate= 74 <br /> Percentage= x 100% ≈172.97%<br />Rate after 2 minutes= 112 bpm<br />Resting rate = 74<br /> Percentage= x 100% ≈151.35% <br />Rate after 3 minutes= 112 bpm<br />Resting rate = 74<br /> Percentage= x 100% ≈151.35% <br />Rate after 4 minutes= 104 bpm<br />Resting rate = 74<br /> Percentage= x 100% = 140.54%<br />Rate after 5 minutes= 100 bpm<br />Resting rate=74<br />Percentage= x 100%= 135.15%<br />How long does it take for your pulse rate to return to within 5% of your resting rate?<br />5% of 74= 3.7<br />74+3.7= 77.7 bpm <br />My lowest pulse rate was 100, which was collected when 5 minutes. So it takes more than 5 minutes for my pulse rate to return to within 5% of my resting rate.<br />What are the variables that could effect your result?<br /><ul><li>Talking to other people while collecting the data.
  2. 2. Move too much while collecting the data.
  3. 3. 15 seconds might not be accurate enough </li></ul>Well, are you healthy?<br />I think I am not very healthy, because a healthy person’s pulse rate should be lowed down very quickly after exercise, but my pulse rite was still very high after 5 minutes from the exercise.<br />Conclusion<br />To make this investigation more accurate, we can make the time to 60 seconds, not 15. That is because if 2 seconds less in 15 seconds, then when I change to 60 seconds, the error will be nearly 10 seconds. <br />
