PHYSICAL EDUCATION
UNIT 3: ATP-PC ENERGY SYSTEM
WORKSHEET
Using the PowerPoint on Energy systems to help you, Complete
and answer the following questions.
As a class, choose three test subjects to thoroughly warm up and then
attempt a series of 50 metre sprints. Allow gradually reduced
recovery periods after each sprint.
- 5 mins
- 3 mins
- 1 min
- 10 secs
Each subject takes their heart rate for 10 secs after each sprint
a) graph and discuss results
b) Write up a report in which you discuss and explain the peak
time for the ATP-PC system, its recovery period and how this
lab demostarted thjis theory.
c) What does ATP stand for? Adenosine Triphosphate
d) What is the difference between the ATP-CP System and the
Anearobic Glycolyisis System?
e) What sports use the ATP-PC system? Weight lifting, high jump,
long jump, 100m run, 25m swim
f) How long does the ATP-PC system last? Up to 10 secs
g) What is the primary energy source of the ATP-PC system?
Stored ATP and CP.
h) What is the chemical process that occurs in ATP-PC system?
ATP  ADP + “energy”
