2. Your hypothesis:
In comparison to my baseline, resting rates, for my first activity, all vital signs will increase. In my second activity, I expect the same results. In my third activity, the pulse and respiratory rates will decrease and the systolic and diastolic rates will increase.
3. Materials and Methods:
For all activities, I will be using a ____ to determine my pulse, systolic, and diastolic rates. I will use a clock and my own superior counting abilities to calculate my respiratory rate. :) In the picture above, is the position I took for my baseline reading. I sat, rested for 10 minutes, then check my vitals. I would wait 10 minutes before taking another vital reading and I did this activity 5 times. I will find the average for each of the pulse, systolic, diastolic, and respiratory rates and put them in a data sheet. (Also, I had my boyfriend step in for the pictures, as I was unsuitable at the moment--sleepy clothes!)
This is what I labeled as "activity 1." In this activity, I laid on the bed for 10 minutes then slowly shifted my body further to the edge of the bed so I was hanging upside down. I took and recorded my vitals and timed my breathing. I did this activity 5 times and calculated the average, again, for each of the vital readings.
In this picture, is "activity 2." This one worked my abs. I hung off the bed, holding myself up for 10 minutes at a time. Afterwards, I repeated the process of taking and recording my vital signs and repeating the process 5 times. Again, I took the mean and recorded that as well.
In this final activity, "activity three," I was ready to take a shower...a long shower. I would be in there for 10 minutes, then half-way dry off to take my vitals once more. As with the other activities, I repeated this process 5 times, took the average, and recorded all the rates. Trust me, 50 minutes in the shower makes a person very wrinkly...and thirsty.
4. Your data:
These two pictures would together be my table of data for this experiment. This is where I recorded each rate throughout the experiment.
This is the graph of the averages of my pulse rates for each activity.
This is the graph for the averages of my respiratory rates for each activity.
This is the graph for the averages of my systolic rates for each activity.
This is the graph for the averages of my diastolic rates for each activity.
5. Analysis of your data. To my surprise my hypotheses were not correct. I had expect that for the first and second activities, all the metabolic rates would have increased in comparison to my baseline readings. I had also expected that for the third activity, the pulse rate and respiratory rates would have decreased and the systolic and diastolic rates would increase. Instead, for both the pulse and respiratory rates, the averages showed that the first activity was below that of the baseline data. The second and third activities showed that the metabolic rates had increased. For the systolic rates, the first and second activities' vitals both decreased, while the third activity metabolic rates increased. Finally, for the diastolic rates, all three activities showed vital signs that had decreased from the baseline, resting data.
6. Problems with your data or technique. I think my data would have been more accurate had I done various activities such as running, swimming, skateboarding, etc., and/or if I had done more activities. I believe I did this experiment correctly, however, as I had even used a doctor prescribed, blood pressure cuff.
7. Conclusion. The blood needs to flow throughout the body and when the body is moving around, the more it does, the harder the heart needs to work in order to get this blood, with the nutrients and oxygen, throughout the body at a faster pace. As seen in this experiment, the more movement I was doing, the higher my metabolic rates would be.
