How does Training Affect Performance?

What is the fuel used in the ATP-PC system?

• CP or PC (Creatine Phosphate)

• Glucose

• Fatty acids

• Amino acids

What is the duration of the ATP-PC system?

• 10 seconds of explosive activity

• 30 minutes of moderate activity

• 2 hours of endurance activity

• 1 minute of high-intensity activity

What causes fatigue in the ATP-PC system?

• When CP stores run out

• When lactic acid builds up

• When oxygen supply is insufficient

• When glycogen stores are depleted

What is the fuel used in the Lactic Acid System?

• Glycogen

• Fatty acids

• Amino acids

• Creatine phosphate

What is the duration of the Lactic Acid System?

• 10 seconds – 2/3 minutes

• Less than 5 seconds

• 5 – 10 minutes

• More than 30 minutes

What causes fatigue in the Lactic Acid System?

• The accumulation of lactic acid

• Depletion of oxygen stores

• Increase in muscle temperature

• Loss of electrolytes

What is the main fuel used in the aerobic system?

• Glycogen, fats, protein

• Carbohydrates only

• Vitamins and minerals

• Water

How long does the aerobic system typically last during exercise?

• 3 minutes onwards

• 0-10 seconds

• 10-60 seconds

• 1-2 minutes

Match the following features with their correct description for the aerobic system:

• When carbohydrate stores run out and fat becomes the dominant fuel source ("hitting the wall")

• Efficiency of ATP production

• 3 minutes onwards

• Duration of system

• CO2 + water + 36xATP

• Cause of fatigue

• Glycogen, fats, protein

• Fuel

• Excellent and most efficient + advantageous bi Product (water + ATP + CO2)

• Bi-products

What is the main purpose of circuit training?

• To develop aerobic capacity and improve muscle endurance, strength, and flexibility

• To only increase muscle size

• To only improve flexibility

• To only develop speed
