anaerobic & aerobic

    Cards (80)

    • What is the main fuel required for exercise according to the study material?
      Carbohydrate
    • Why is water important in the breakdown and transport of carbohydrates?
      Water allows blood to move quickly and smoothly through the blood vessels
    • What nutrient is primarily used for growth and repair of muscles but can also produce energy in extreme conditions?
      Protein
    • Under what conditions is fat used as a rich source of energy?
      At a low intensity
    • What determines the predominant energy systems used during exercise?
      Intensity, duration, and nutrients
    • What is the primary difference between aerobic and anaerobic exercise?
      Aerobic uses oxygen, anaerobic does not
    • What is the primary fuel source for the aerobic energy system?
      Glucose from carbohydrates
    • Why is the Creatine Phosphate (CP) system used for explosive, high-intensity, short-duration exercises?
      It supplies energy faster than all other energy systems
    • What is the waste product of the Lactic Acid System?
      Lactic acid
    • What happens when an athlete reaches the anaerobic threshold?
      The aerobic system cannot supply energy efficiently enough, so the lactic acid system is used
    • What is VO2 max?
      The maximal volume of oxygen that the body can take in and use
    • How is the oxygen debt repaid after exercise?
      By reducing the intensity of exercise, allowing more oxygen into the body's systems
    • What are the waste products of the aerobic energy system?
      CO2 and H2O
    • What is the aerobic threshold?
      The point at which training becomes predominantly aerobic
    • What is the equation for aerobic respiration?
      Glucose + Oxygen = Energy + Carbon dioxide + water
    • What are the drawbacks of anaerobic respiration?
      Fuel quickly runs out, lactic acid is produced, causing fatigue and discomfort
    • What type of respiration is used in sprinting?
      Anaerobic
    • What type of respiration is used in hiking?
      Aerobic
    • What type of respiration is used in football?
      Both aerobic and anaerobic
    • What are the short-term effects of exercise on the cardiovascular system?
      Increase in stroke volume, heart rate, cardiac output, and blood pressure
    • What are the short-term effects of exercise on the respiratory system?
      Increase in breathing rate, tidal volume, and minute ventilation
    • What happens to the muscular system during short-term exercise?
      Increase in temperature, pliability, and muscle fatigue
    • What is the effect of exercise on the skeletal system?
      Improved mobility at the joint allowing easier movement
    • What are the key differences between the aerobic and anaerobic energy systems?
      • Aerobic: Uses oxygen, low to moderate intensity, long duration, produces CO2 and H2O
      • Anaerobic: Does not use oxygen, high intensity, short duration, produces lactic acid
    • What are the benefits and limitations of the Creatine Phosphate (CP) system?
      Benefits:
      • Supplies energy faster than other systems
      • No waste products produced
      • Benefits muscular strength, power, SAQ, reaction time

      Limitations:
      • Short duration (0-10 seconds)
      • CP stores deplete quickly
    • What are the benefits and limitations of the Lactic Acid System?
      Benefits:
      • Produces energy at moderate to high intensity
      • Benefits power, muscular endurance, and speed

      Limitations:
      • Produces lactic acid, causing fatigue and discomfort
      • Short duration (60-90 seconds)
    • What are the benefits and limitations of the Aerobic Energy System?
      Benefits:
      • Produces energy at low to medium intensity for long duration
      • Benefits cardiovascular endurance and recovery

      Limitations:
      • Requires oxygen
      • Slower energy production compared to anaerobic systems
    • What are the key differences between trained and untrained athletes in terms of anaerobic threshold?
      • Untrained athletes reach anaerobic threshold at 70-80% VO2 max
      • Elite-trained athletes reach anaerobic threshold at 85-90% VO2 max
    • What are the short-term effects of exercise on the cardio-respiratory system?
      • Increase in oxygen uptake and transport
      • Increase in CO2 removal
    • What are the short-term effects of exercise on the energy system?
      • Increase in lactic acid production
    • What are the short-term effects of exercise on the muscular system?
      • Increase in temperature
      • Increased pliability (elasticity)
      • Muscle fatigue
    • What are the short-term effects of exercise on the skeletal system?
      • Improved mobility at the joint allowing easier movement
    • What are the key differences between aerobic and anaerobic respiration?
      • Aerobic: Requires oxygen, slower, produces CO2 and H2O
      • Anaerobic: Does not require oxygen, faster, produces lactic acid
    • What are the biproducts of aerobic respiration?
      • Water (H2O)
      • Carbon dioxide (CO2)
