You have probably heard many times that "there is a relationship between physical fitness and heart activity".
What is that relationship?
In order to answer that question, please run the simulation.
simulation
The imitation of an object or an action.
Example: The imitation of an active power plant
a.
Select low physical fitness.
b.
Select a state of rest.
c.
Note the heart rate in this state.
d.
Now, select a state of exertion.
e.
Note the heart rate in this state.
f.
Repeat for the two other levels of physical fitness (medium and high).
1.
What is heart rate? Select the sentence that explains it.
The number of times that the heart contracts (beats), per minute.
The number of times that the heart contracts (beats) during exertion.
The amount of blood that the heart pumps while contracting.
The amount of blood that the heart pumps during exertive activity.
2.
Run the simulation and complete the heart rate data in the following table:
Complete the two left-hand columns according to the simulation data, and calculate the right-hand column according to data you collected from the simulation.
Heart rate at rest
Heart rateduring exertion
Increase in heart rate
Person with low physical fitness
Person with medium physical fitness
Person with high physical fitness
3.
The highest heart rate in both activity states (at rest and during exertion) will be observed in a person whose physical fitness is:
The lowest heart rate in both activity states (at rest and during exertion) will be observed in a person whose physical fitness is:
The greatest increase in heart rate following exertive activity will be observed in a person whose physical fitness is:
4.
Use the table to summarize your findings.
Complete the following sentences:
During exertive activity, the heart rate .
The greatest increase in heart rate is observed in people whose physical fitness is , compared with people whose physical fitness is .
5.
Explain: Why does exertive physical activity affect the heart rate?
6.
Explain: Why does physical fitness affect heart rate?

And now, for a true story:
John and Alan are good friends.
John plays tennis four times a week, whereas Alan spends many hours playing computer games.
One day, John invited Alan to his apartment, which is located on the fourth floor of his building. When they arrived at the building, they found that the elevator was out of order.
Having no other choice, the two friends climbed up the stairs.
When they finally reached the fourth floor, they checked their heart rates and discovered a substantial difference between them.
Based on the story you just read, complete the following sentences:
Before climbing the stairs:
Alan's heart rate was
than John's heart rate.
After climbing the stairs:
Alan's heart rate was
than John's heart rate.
The difference between the heart rates before and after climbing the stairs:
The difference for Alan was
than for John
8.
Explain: Why is there a difference between Alan's heart rate and John's heart rate?
9.
After John and Alan reached the fourth floor, and after they compared their heart rates, John said to his friend: "You should join my tennis class!".
Explain: Why did John suggest that Alan come play tennis with him?
In your answer, make sure to use the words heart rate.
