Heart Rate Recovery After Exercise
Introduction
The human heart has a resting rate of 60-100 beats per minute. This is due to the normal rhythm produced by the
sinoatrial (SA) node, and input from the brain. The primary purpose of the heart is to pump blood throughout the body,
which delivers oxygen and nutrients, while removing carbon dioxide and other metabolic wastes from the body cells.
When additional oxygen is required, such as during oxygen, the heart rate will increase. This effect, however, can vary
widely from person to person.
Problem
What variables have the greatest impact on human heart rate before, during, and after exercise?
Observations
1. List any variables that you suspect would influence heart rate before, during, and after exercise. These must be
measurable differences from person-to-person.
2. Choose three of the variables above that you predict will have the biggest impact on measured heart rate.
3. Give a brief explanation why you believe those three variables will affect heart rate the most, based on your
current understanding of the human body.
Hypothesis
Write a hypothesis predicting what impact each variable will have on the average person’s heart rate. The hypothesis
should be written to express two groups that will be used as comparison study. The independent and dependent
variables should each be underlined.
For example:
“Individuals with a history of tobacco smoking are predicted to have a greater increase in heart rate
independent variable
dependent variable
and a longer recovery time than individuals who do not smoke.”

4. Hypothesis for first tested variable:
5. Hypothesis for second tested variable:
6. Hypothesis for third tested variable:
Procedure
Develop a procedure to be used by each participant in the study. Consider each of the following questions:




How will resting heart rate be measured?
What type of exercise will be conducted?
How long will the exercise last?
How will heart rate be measured as the body recovers from exercise?
Write your procedure below, in a numbered step-by-step format. This procedure must be followed exactly by each
participant in the study.

Data
Tabulate and record the number of individuals within each comparison group of your study. Calculate the average heart
rate before the exercise, and during the intervals following exercise. Give your data table a title based on the variables
studied. See the example below:

Analysis
Make a line graph representing the change in heart rate before, immediately after, and in the resting period following
exercise for each of your three studied comparison groups. Each group (male, female, smokers, nonsmokers, etc.)
should have its own, separate line. Label the graph, as well as each axis. Heart rate should go on the y-axis, time on the
x-axis.

Calculate the percent change in heart rate that occurred for each group immediately after the exercise, and during the
two recovery intervals.

After Exercise
Make a bar graph representing the percent change in heart rate for each group after exercise, and during the resting
periods following exercise. The y-axis should represent percent change, while the x-axis will represent each comparison
group. Label the graph and each axis.

Conclusion
Your conclusion should include each of the following:

Summarize the purpose of the heart and cardiovascular system.

Why would heart rate increase following a period of heavy exercise?

Restate your original hypothesis, and explain what background knowledge you used to make these
predictions.

Does the data support or refute your original hypothesis? Make specific references to the recorded
observations in your data tables or your graphs.

Do you believe this data is accurate? Assuming all the heart rates were measured accurately, what
are some other possible sources of error?

How could this experiment be revised to eliminate these sources of error?
