Transcript of Heart Rate and Lung Capacities Correlation

Heart Rate and Lung Capacities Correlation

The purpose of this activity is to find out if a persons lung capacity affects their resting heart rate. Its also to see if there is a difference in lung capacity depending on the position they are in.
Research Question
It is hypothesized that lung capacity will affect resting heart rate and position will affect the lung capacity, the position that allows more oxygen is hypothesized to be the sitting position.
The theory is that a person who has a higher lung capacity can take more oxygen into their body making more oxygenated blood hence allowing their resting heart rate to be lower.
Background Theory
-1 spirometer
-1 chair
-1 heart rate sensor
-10 test subjects
Lab Procedure
1. Set up Spirometer by pushing the on button and hitting record
2. Set up the heart rate sensors by plugging it in and hooking it up to the computer
3. Get 1 test subject to put their hand on the desk while sitting
4. Place the heart rate sensor on their index finger leave there for 30 seconds
5. Record the average resting heart rate
6. Put a graph on the spirometer
7. While test subject is still sitting get them to blow into the spirometer
8. Get test subject to lay down
9. While laying down get them to blow in the spirometer again
10. Label spirometer data tables
11. Repeat for next test subject

-9 out of 10 test subjects while laying down had a lower lung capacity than when sitting.
-Results may very because some test subjects did the exercise experiment first.
- One test subject has asthma which may change results.

-The average lung capacity for the boys is 3.98 and average heart rate is 82.6 beats per min.

-The average lung capacity for the girls is 3.36 and average heart rate is 86.2 beats per min. Which is higher than the boys but their lung capacity is smaller.
The results are not in favour to the initial hypothesis and theory. The graph done up shows that there is a slight positive correlation but it isn't enough to say there is a definite connection between heart rate and lung capacity. The tests done do show the correlation between position and lung capacity.
The data did not support the original question which was that there is a correlation between heart rate and lung capacity. In this experiment however the results did support the question position affects lung capacity. The results show while sitting down more air is taken in then while laying down, though in this experiment there was one outlier to the data.

Errors that may have effected the results are the test subjects doing other experiments before this one that would have included exercise which would affect resting heart rates.

Questions that came from this experiment would be why does the position affect your lung capacity and it would be interesting to do a future research or experiments to find out.
