(26 cards)
What are the three primary energy systems used in running?
The ATP-PC system, the anaerobic glycolysis system, and the aerobic system.
True or False: The ATP-PC system is primarily used for long-distance running.
False
Fill in the blank: The ________ system provides energy for short, high-intensity efforts lasting up to 10 seconds.
ATP-PC
Which energy system is utilized during moderate to high-intensity running lasting from 30 seconds to 2 minutes?
Anaerobic glycolysis system
True or False: The aerobic system requires oxygen to produce energy.
True
What is the primary byproduct of the anaerobic glycolysis system?
Lactic acid
During which energy system does the body primarily utilize carbohydrates and fats?
Aerobic system
Multiple Choice: Which energy system is most efficient for endurance running?
Aerobic system
What is the duration of energy production for the ATP-PC system?
Up to 10 seconds
True or False: The anaerobic glycolysis system can sustain energy production for long periods.
False
Fill in the blank: The ________ system is dominant during sprinting events.
ATP-PC
What type of running primarily uses the aerobic energy system?
Long-distance running
Multiple Choice: Which of the following activities primarily uses the anaerobic glycolysis system?
400-meter sprint
How does the body primarily replenish ATP during the aerobic system?
Through the oxidation of carbohydrates and fats.
True or False: The ATP-PC system is anaerobic.
True
What happens to lactic acid during recovery from anaerobic exercise?
It is converted back to glucose in the liver.
Fill in the blank: The ________ system becomes more dominant as exercise duration increases.
Aerobic
What is the primary fuel source for the aerobic system?
Fats and carbohydrates
Multiple Choice: Which energy system has the fastest ATP production rate?
ATP-PC system
True or False: The anaerobic systems can operate in the absence of oxygen.
True
What is the transition point where anaerobic metabolism begins during running?
Around 30 seconds of high-intensity effort.
Fill in the blank: The predominant energy system for a marathon runner is the ________ system.
Aerobic
What is the main advantage of aerobic metabolism?
It can produce ATP for extended periods.
Multiple Choice: Which system is least utilized during a 100-meter dash?
Aerobic system
