Soc18: Anaerobic Aerobic Exercise And Energy Systems Flashcards
What is aerobic exercise?
Aerobic exercise is physical activity that relies on the use of oxygen to fuel the body for extended periods.
What is anaerobic exercise?
Anaerobic exercise is high-intensity physical activity that does not rely on oxygen and is performed in short bursts.
True or False: Aerobic exercises are typically performed at a low to moderate intensity.
True
What type of energy system is predominantly used during aerobic exercise?
The oxidative energy system.
What energy system is primarily engaged during short, high-intensity activities?
The phosphagen energy system.
Fill in the blank: Anaerobic metabolism produces _____ as a byproduct.
lactic acid
What is the primary fuel source for aerobic exercise?
Carbohydrates and fats.
What is the duration of activity that typically engages the aerobic system?
Activities lasting longer than 2 minutes.
Which energy system is used for activities lasting from 10 seconds to 2 minutes?
The anaerobic glycolysis system.
True or False: Aerobic exercise can improve cardiovascular endurance.
True
What is the main characteristic of the phosphagen energy system?
It provides immediate energy for short-duration, high-intensity activities.
Multiple Choice: Which of the following is NOT an example of aerobic exercise? A) Running B) Weightlifting C) Swimming
B) Weightlifting
What is the role of oxygen in aerobic metabolism?
Oxygen is used to convert carbohydrates and fats into energy.
Fill in the blank: The _____ system produces ATP without the use of oxygen.
anaerobic
Which energy system is responsible for ATP production during the first 10 seconds of high-intensity exercise?
The phosphagen system.
True or False: Aerobic exercises can lead to increased muscle mass.
False
What type of exercise is best for improving anaerobic capacity?
High-intensity interval training (HIIT).
What is the primary adaptation of the body to regular aerobic training?
Increased stroke volume and cardiac output.
Fill in the blank: The _____ system is the slowest to provide energy but can sustain activity for long durations.
oxidative
What is the primary source of energy during prolonged aerobic exercise?
Fat stores.
Multiple Choice: Which of the following best describes the anaerobic system? A) Slow energy production B) Quick energy production C) Continuous energy production
B) Quick energy production
What is the importance of recovery time in anaerobic training?
Recovery time allows for the replenishment of ATP and phosphocreatine stores.
True or False: Aerobic exercise primarily utilizes fast-twitch muscle fibers.
False
What are the two main types of muscle fibers involved in aerobic and anaerobic exercise?
Slow-twitch (aerobic) and fast-twitch (anaerobic).
Fill in the blank: The _____ energy system can be trained through activities like sprinting and heavy lifting.
anaerobic
What is the effect of anaerobic exercise on body composition?
It can increase muscle mass and decrease fat mass.
What is the significance of lactate threshold in exercise performance?
It indicates the point at which lactic acid starts to accumulate in the bloodstream.
