Energy systems Flashcards
What is the aerobic energy system?
A system that produces energy through the use of oxygen for prolonged activities.
It is primarily utilized during low to moderate intensity activities such as long-distance running.
What is the anaerobic energy system?
A system that produces energy without the use of oxygen, typically for short bursts of high-intensity activity.
It includes both the ATP-CP system and the lactic acid system.
What are the two primary energy systems in the human body?
Aerobic and anaerobic energy systems.
True or False: The anaerobic energy system requires oxygen to produce energy.
False.
Fill in the blank: The aerobic energy system predominantly uses __________ to produce energy.
oxygen.
What is the primary fuel source for the anaerobic energy system?
Carbohydrates.
During which type of exercise is the anaerobic energy system primarily utilized?
High-intensity, short-duration exercise.
What is the main byproduct of the anaerobic energy system?
Lactic acid.
Which energy system is more efficient for long-duration activities?
Aerobic energy system.
Multiple Choice: Which of the following activities primarily uses the aerobic energy system? A) Sprinting B) Marathon running C) Weight lifting
B) Marathon running.
What is the duration limit of energy production for the anaerobic energy system?
Up to 1 minutes.
True or False: The aerobic energy system can sustain energy production for hours.
True.
What type of exercise primarily relies on the aerobic energy system?

True or False: The aerobic energy system can use fats as a fuel source.
True.
Fill in the blank: The aerobic system predominantly occurs in the __________ of cells.
mitochondria.
What is the primary disadvantage of the anaerobic energy system?
Production of lactic acid leading to fatigue.
Multiple Choice: Which of the following is NOT a factor affecting the energy systems? A) Intensity of exercise B) Duration of exercise C) Age of the individual
C) Age of the individual.
What happens to lactic acid during recovery?
It is converted back to glucose or used as an energy source.
True or False: The aerobic energy system is primarily used during high-intensity, short bursts of activity.
False.
What is the role of oxygen in the aerobic energy system?
To help convert carbohydrates and fats into ATP.
Fill in the blank: The __________ system provides energy for activities like sprinting and weight lifting.
anaerobic.
Which energy system is primarily used during a 400-meter sprint?
Anaerobic energy system.
True or False: Aerobic energy production is faster than anaerobic energy production.
False.
What is the role of the liver in the recovery of lactic acid?
To convert lactic acid back to glucose through gluconeogenesis.
Fill in the blank: The __________ energy system is predominantly used during rest and low-intensity activities.
aerobic.
Multiple Choice: Which of the following is a characteristic of the aerobic system? A) Produces lactic acid B) Requires oxygen C) Short duration
B) Requires oxygen.
What is the significance of the oxygen debt?
It refers to the amount of oxygen required to restore the body after exercise.
True or False: The anaerobic energy system can only use carbohydrates for energy.
True.
What is the primary energy source for the aerobic system during prolonged exercise?
Fats.
Fill in the blank: The anaerobic glycolytic system can produce energy quickly but is limited by __________ accumulation.
lactic acid.
What are the main factors that determine which energy system is used during exercise?
Intensity and duration of the exercise.
True or False: The aerobic system can only produce energy from glucose.
False.
Which type of training can enhance the efficiency of the aerobic energy system?
Endurance training.
Fill in the blank: The __________ energy system is crucial during activities such as sprinting and jumping.
anaerobic.
What happens to the body during the transition from anaerobic to aerobic energy production?
Oxygen uptake increases, and lactic acid production decreases.
