Aerobic and anaerobic exercise

• What is aerobic exercise?

  Aerobic exercise takes place in the presence of oxygen.
• How does the heart function during aerobic exercise?

  The heart can supply all the oxygen the working muscles need during steady, long-duration exercise.
• What is the source of energy for working muscles during aerobic exercise?

  The energy comes from carbohydrates, which are converted into glucose and oxygen.
• What are the byproducts of aerobic energy production?

  The byproducts are carbon dioxide and water.
• What happens to carbon dioxide and water produced during aerobic exercise?

  Carbon dioxide is expelled through the lungs, while water is also released.
• Why is producing energy aerobically preferred by the body?

  It allows the body to work for a long period of time at low to moderate intensity.
• What are examples of aerobic exercise?

  • Long-distance running
  • Endurance cycling
  • Long-distance swimming
• What is the definition of aerobic exercise in terms of intensity?

  Aerobic exercise is working at a low to moderate intensity.
• What is anaerobic exercise?

  Anaerobic exercise takes place in the absence of enough oxygen.
• What happens to the heart and lungs during anaerobic exercise?

  They cannot supply enough blood and oxygen to the working muscles.
• How is glucose converted into energy during anaerobic exercise?

  Glucose is converted into energy without the presence of oxygen.
• What waste product is produced during anaerobic exercise?

  Lactic acid is produced as a waste product.
• What is Excess Post-exercise Oxygen Consumption (EPOC)?

  EPOC is the amount of oxygen needed to recover after exercise.
• What characterizes EPOC after anaerobic exercise?

  It is characterized by an increased breathing rate and deeper breathing.
• What does EPOC help the body do after anaerobic exercise?

  EPOC helps replenish the body with oxygen and convert lactic acid into glucose, carbon dioxide, and water.
• What are examples of anaerobic exercise?

  • Sprinting (100 meters or 200 meters)
  • Activities requiring fast, powerful muscular contractions (e.g., triple jump)
• How long can the body sustain anaerobic exercise?

  The body can only sustain anaerobic exercise for short periods, approximately 60 seconds.
• What are the effects of aerobic versus anaerobic exercise?

  • Aerobic exercise: longer duration, lower intensity, uses oxygen.
  • Anaerobic exercise: shorter duration, higher intensity, does not use oxygen.
• What is the importance of recovery after vigorous exercise?

  Recovery is essential to ensure the body recuperates from vigorous exercise.
• What are methods of recovery after vigorous exercise?

  • Cooling down
  • Manipulating or controlling diet
  • Ice baths or massage
• Why is cooling down important after exercise?

  Cooling down helps the body gradually return to a resting state.
• How does stretching contribute to recovery?

  Stretching helps maintain blood circulation and aids in the removal of lactic acid.
• What role does diet play in recovery?

  Manipulation of diet is essential to help the body recover and replenish fluids lost during exercise.
• What is carbohydrate loading?

  Carbohydrate loading involves increasing complex carbohydrate intake before an event to enhance performance and recovery.
• How does protein intake affect recovery?

  Protein intake is important for muscle repair and growth after exercise.
• What is the purpose of ice baths or massages after exercise?

  Ice baths and massages help reduce muscle soreness and speed up recovery.
• What does DOMS stand for?

  DOMS stands for Delayed Onset Muscle Soreness.
• What is DOMS?


  DOMS is the pain felt in muscles the day after exercise.
• How does the body flush lactic acid after exercise?

  The body flushes lactic acid by increasing blood flow and oxygen delivery to the muscles.
• What is the effect of ice baths on blood circulation?

  Ice baths constrict blood vessels, which helps reduce swelling and soreness.
• What is the relationship between exercise intensity and hydration needs?

  The amount of water needed depends on exercise intensity, temperature, and humidity.
