Question

aerobic vs. anaerobic exercises: circle the best answer for each question.

1. which of the following is an example of an aerobic exercise?

a) sprinting
b) weightlifting
c) swimming
d) jumping

1. what is the primary energy source for anaerobic exercises?

a) oxygen
b) glycogen
c) fat
d) protein

1. which of the following is a health benefit of aerobic exercises?

a) building muscle strength
b) improving lung capacity
c) increasing bone density
d) enhancing power

1. what type of exercise is high - intensity and performed in short bursts?

a) aerobic
b) anaerobic
c) flexibility training
d) endurance training

1. which of the following is not an example of an anaerobic exercise?

a) sprinting
b) weightlifting
c) brisk walking
d) high - intensity interval training (hiit)

Explanation:

1. Aerobic exercises require oxygen and are sustained. Swimming is a common aerobic exercise. Sprinting, weightlifting are more anaerobic. Jumping can be part of anaerobic or plyometric activities.
2. Anaerobic exercises rely on stored energy like glycogen as they occur too quickly for oxygen - based metabolism to fully kick in.
3. Aerobic exercises improve lung capacity as they involve continuous breathing and oxygen - use over time. Building muscle strength is more associated with resistance training, increasing bone density is more related to weight - bearing exercises, and enhancing balance is not a primary benefit of aerobics.
4. Anaerobic exercises are high - intensity and short - burst activities. Aerobic exercises are more sustained. Flexibility and endurance training are different types of training not characterized by short - burst high - intensity.
5. Brisk walking is a low - to - moderate intensity aerobic exercise. Sprinting, weightlifting, and HIIT are anaerobic due to their high - intensity and short - burst nature.

Answer:

1. c. Swimming
2. b. Glycogen
3. b. Improving lung capacity
4. b. Anaerobic
5. c. Brisk walking
