Creatine
What is the approximate duration that the ATP-PC system can supply energy?
1–2 seconds
6–12 seconds
30–60 seconds
2–4 minutes
During a 400m sprint, which energy system is predominantly used?
Aerobic
ATP-PC
Lactic acid
Fat oxidation
Which system has the fastest rate of recovery?
Aerobic

Heat
What is the predominant energy system for a marathon runner?
ATP-PC
Lactic acid
Aerobic
Creatine phosphate
The ATP-PC system recovers quickly due to:
Resynthesis of glycogen in muscles
Restoration of creatine phosphate using oxygen
Removal of lactic acid via the liver
Increased fat metabolism
