1.3.1 Definitions and differences

• Aerobic exercise requires the use of oxygen to meet the body's energy demands.
• What is the definition of anaerobic exercise?

  Does not require oxygen
• Anaerobic exercise relies on oxygen as its primary energy source.

  False
• Anaerobic exercise is characterized by short bursts of high-intensity exertion.


  True
• The aerobic system uses oxygen to convert carbohydrates and fats.
• What is the key characteristic of aerobic exercise?

  Sustained and moderate exertion
• What is the primary energy source for aerobic exercise?

  Oxygen
• What does aerobic exercise improve in the respiratory system?

  Lung capacity
• The intensity of aerobic exercise is moderate.


  True
• Anaerobic exercise is characterized by high-intensity and short-duration bursts of exertion.
• Order the characteristics of anaerobic and aerobic exercise based on the table provided:

  1️⃣ Energy Source: Limited oxygen, stored energy ||| Energy Source: Oxygen

  2️⃣ Intensity: High ||| Intensity: Moderate

  3️⃣ Duration: Short bursts ||| Duration: Sustained
• Aerobic exercise is performed at a moderate intensity for a sustained period.
• Anaerobic exercise breaks down glycogen without oxygen.


  True
• Anaerobic exercise is characterized by high-intensity and short-duration bursts of exertion.
• In anaerobic exercise, the primary energy source is stored glycogen.
• Match the impact with the type of exercise:

  Increased endurance ↔️ Aerobic exercise

  Increased muscle strength ↔️ Anaerobic exercise
• What is the definition of aerobic exercise?

  Uses oxygen for energy
• Order the characteristics of aerobic and anaerobic exercise based on the table provided:

  1️⃣ Energy Source: Oxygen ||| Energy Source: Limited oxygen, stored energy

  2️⃣ Intensity: Moderate ||| Intensity: High

  3️⃣ Duration: Sustained ||| Duration: Short bursts
• What is the intensity level of aerobic exercise?

  Moderate
• What energy system is primarily used in aerobic exercise?

  Aerobic system
• Match the primary system with the type of exercise:

  Aerobic system ↔️ Aerobic exercise

  Anaerobic lactic acid system ↔️ Anaerobic exercise
• Aerobic exercise involves moderate intensity and sustained duration.


  True
• Anaerobic exercise promotes the growth of fast-twitch muscle fibers.
