3. 15 seconds might not be accurate enough 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 />

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 />,[object Object]](https://image.slidesharecdn.com/areyouhealthy-110418215618-phpapp02/85/Are-you-healthy-1-320.jpg)
