Lab Assignment Title: Cardiovascular Stress
Date: 2017-06-27
Background


Before this lab, we went in with the understanding that heart rate increases when the body is under stress. For
example, heart rate typically increases during exercise.
This investigation may add to our knowledge by providing an understanding of the relationships between the
changes in human anatomy and physiology during cardiovascular stress.
Purpose / Objective(s):



To put stress on our cardiovascular system
To make observations and record the data about response to cardiovascular stress
To make calculations about the relationships between the data collected
Hypothesis:


Individuals that exercise their CV system more frequently will have more constant and low vital signs
Individuals that exercise their CV system regularly might be more equipped to handle stress put on their body
because their body has been conditioned to handle the stress
Subject(s):
Table #1: Subject characteristics
The following table characterizes the subjects in this study:
Heights ranged from a short of 60 to a tall of 72, weights ranged from 100 to 210, age ranged from 19 to 41 and BMI
ranged from 19 to 30.

Procedures and Methods
1. Record height, weight, age, and BMI into
the CV Stress data tables
2. Cleaned the stethoscope using
antibacterial hand sanitizer on tissue
paper and wipe dry.
3. Placed the sphygmomanometer on the
specimen’s bicep.
4. Lined up the arrows on the
sphygmomanometer and diaphragm of the
stethoscope with the brachial artery of the
specimen.
5. Inflated the blood pressure cuff and looked
and listened for systolic and diastolic
pressure on the meter.
6. A wrist cuff was also used to measure
systolic and diastolic pressure.
7. Monitored heart and respiratory rate
8. Recorded resting vital signs while sitting
and standing
9. Run laps in the quad until heart rate has
become elevated
10. Right after running laps, repeated steps 26 to record peak vital signs
11. Wait three minute before repeating steps
2-6 again to record 3-minute recovery vital
signs
12. Wait three more minutes before repeating
steps 2-6 again to record 6-minute
recovery vital signs
13. Wait four more minutes before repeating
steps 2-6 again to record 10-minute
recovery vital signs
14. Subjects were interviewed regarding their
individual levels of physical activity as
shown in Table 1

Results / Data:
Graphs
 Attachment 1
o Shows The Average BMI of Self, Males, and Females. They all fall within 7 points of eachother however
females and self are considered at a healthy BMI as a group where the males are considered overweight
as a whole.
 Attachment 2
o Shows the Correlation of Age and BMI in Females. The data proved that age negatively affects BMI. As
females get older their BMIs increase. The trend line indicates that approximately for each additional
year there is a 4-point increase in BMI.
 Attachment 3
o Shows the Males’ Heart Rate for Resting and Elevated. These data points were all scattered for
everyone. For males 1 and 5, their heart rates consistently increased. For male 3, his heart rate went
from decreasing to increasing to decreasing. Which is the typical linear regression for this data. For male
4, his heart rate consistently decreased. And for male 2, his heart rate went from increasing to
decreasing to increasing.
 Attachment 4
o Shows the Correlation of Age and BMI in Males. Similar to the data in displayed for females, there was a
negative correlation between age and BMI. The trend line indicates that approximately for each
additional year there is a 1-point increase in BMI.
 Attachment 5
o Shows the Females’ Heart Rate for Resting and Elevated. All 5 females heart rates displayed an
increasing progression on the graph. The data might prove that females exercise more often than males.
 Attachment 6
o Shows the Heart Rate at 3, 6, and 10-minute Recovery after peak for males. Data was consistent
however there seemed to be an error in measuring male 4’s vital signs due to the inconsistency in heart
rate. Despite that one data point, over time, each male’s heart rate remained consistent.
 Attachment 7
o Shows the Heart Rate at 3, 6 and 10-minute Recovery after peak for females. It didn’t appear to have a
significant decrease however their individual heart rates did level out. Over time, for each individual
female their heart rate did stay constant or decrease.
Analysis / Discussion:





In attachments 2 and 4, the Correlation of Age and BMI of Females vs The Correlation of Age and BMI of Males,
it was determined that there was a positive correlation.
In both females and males, an increase in age would result in an increase in BMI. In females, there was a 4x
steeper increase in the trend line which could indicate females’ BMI will be more affected by age.
In attachments 6 and 7, the Heart Rate at 3, 6, and 10-minute Recovery after peak for males and the Heart Rate
at 3, 6 and 10-minute Recovery after peak for females.
It was determined that after peak over time heart rate will continue to decrease.
Our hypothesis was validated; Attachment 6, shows the Heart Rate at 3, 6, and 10-minute Recovery after peak
for males, the males with more frequent exercise of their CV system their vital signs would remain constant and
low. The males see Table 1, that exercised more frequently than females returned to lower heart rates than
females. By comparing the heart rate of males and females we can see that males reach a heart rate of about 60
by 10 minute recovery while females reach a heart rate of about 80 by 10 minute recovery.

Conclusions / Further Considerations:






The higher the weight, the higher the BMI.
There seems to be a correlation between weight and BMI since the more weight, the harder the heart must pump
blood to the rest of the body.
This understanding allows us to further expand our knowledge by providing new perspective of the
cardiovascular system and how stress affects it.
A question this lab has proposed is; if we were to expand our sample size, how would this affect our results?
Some research that could be done following this experiment is to research some relationships between the
relationships of the CV system and stress.
Another area of investigation to help further our understanding would be to conduct this experiment again with a
larger sample size in a more controlled environment.
