Exercise Physiology Quiz

What is the term for the reliance on phosphocreatine and anaerobic glycolysis in the first few minutes of exercise?

• Oxygen Deficit

• Oxygen Surplus

• Aerobic Threshold

• Anaerobic Capacity

What does EPOC stand for in the context of exercise physiology?

• Excess Post-exercise Oxygen Consumption

• Elevated Pre-exercise Oxygen Consumption

• Enhanced Physical Output Capacity

• Extended Post-exercise Output Calculation

Once steady-state is reached, which two primary sources are relied upon to fuel exercise?

• Fat and CHO

• Protein and CHO

• Fat and Protein

• Glucose and Protein

Which factors dictate the proportion of ATP from each source during exercise?

• Intensity, Duration, and Fuel Availability

• Speed, Strength, and Stamina

• Flexibility, Balance, and Coordination

• Power, Agility, and Endurance

Graph showing the crossover concept of energy from carbohydrates and fat during exercise

• Carbohydrates are the primary energy source at low intensity

• Fat is the primary energy source at high intensity

• The crossover point is where energy from fat surpasses carbohydrates

• Protein becomes the main energy source during exercise

Which of the following is a source of carbohydrates (CHO) used for exercise?

• Intramuscular Triglycerides

• Circulating Free Fatty Acids

• Muscle Glycogen

• Plasma FFA

What impacts fuel selection within CHO and FAT sources during exercise?

• Temperature and Humidity

• Intensity and Duration

• Altitude and Pressure

• Time of Day

Which of the following is a source of fat used for exercise?

• Circulating glucose from Liver glycogen

• Muscle Glycogen

• Intramuscular Triglycerides

• Plasma glucose

What happens to the contribution of energy sources during longer duration exercise?

• It shifts towards the muscle.

• It shifts away from the muscle.

• It remains constant.

• It shifts towards carbohydrates.

What effect does exercise training have on the crossover point?

• Shifts it to the left

• Shifts it to the right

• Keeps it the same

• Eliminates it
