Laboratory Report
LABORATORY REPORT
Activity:
Effect of Exercise on Cardiac Output
Name:
Kristin Bautista
Instructor:
Kim Shahi
Date:
08.20.2023
Predictions
1. During exercise
HR will increase
2. During exercise
SV will increase
3. During exercise
CO will increase
Materials and Methods
1. Dependent Variable
EDV, ESV, and cardiac cycle length
2. Independent Variable
level of physical activity (resting or exercise)
3. Controlled Variables
age, weight, height, health, gender
4. What instrument was used to measure cardiac volumes?
MRI was used to measure cardiac volumes. It generated in detail pictures of the body organs and tissues.
5. Does the instrument used to measure cardiac volume use X-Rays? Explain.
No. MRI measures cardiac volum because it produces a detailed view of the anatomical structures and tissues.

1. Resting and exercising cardiac cycle length
a. What was the average resting cardiac cycle length?
The average resting cardiac cycle lenght is 822.
b. What was the average exercising cardiac cycle length?
The average exercising cardiac cycle length is 401.
c. The range of normal resting cardiac cycle length is between 818 and 858 ms. Did average cardiac cycle length increase, decrease, or not change with exercise?
The average cardiac cycle decreased.

a. What was the average resting EDV?
The average resting EDV is 138.
b. What was the average exercising EDV?
The average exercising EDV is 140.
c. The range of normal resting EDV is between 135 and 145 ml for these subjects. Did average EDV increase, decrease, or not change with exercise?
The average EDV lenght is increased.
3. Resting and exercising ESV
a. What was the average resting ESV?
The average resting ESV is 73.
b. What was the average exercising ESV?
The average exercising ESV is 33.
c. The range of normal resting ESV is between 65 and 75 for these subjects. Did average ESV increase, decrease, or not change with exercise?
