Fatigue & Recovery Quiz

What is the main fuel for ATP when glycogen stores are depleted?

• Vitamins

• Fats

• Carbohydrates

• Proteins

Answer explanation

When glycogen stores are depleted, the main fuel for ATP production is fats. Fats are broken down into fatty acids, which are then used to generate ATP through the process of beta-oxidation.

How long do glycogen stores last during continuous high intensity activity?

• 30-60 minutes

• 60-90 minutes

• 90-120 minutes

• 120-150 minutes

Answer explanation

During continuous high intensity activity, glycogen stores typically last for 90-120 minutes. This is the correct choice.

What is the process by which lactate is moved from one location to another for energy production?

• Electron transport chain

• Glycolysis

• Krebs cycle

• Lactate shuttle

Answer explanation

Lactate is moved for energy production through the process called Lactate shuttle.

What is the final exercise intensity at which blood lactate remains relatively stable known as?

• Lactate Saturation Point

• Lactate Equilibrium Point

• Lactate Threshold

• Lactate Inflection Point

Answer explanation

The final exercise intensity at which blood lactate remains relatively stable is known as the Lactate Inflection Point.

What is the highest intensity of aerobic exercise an athlete can sustain without the rapid accumulation of hydrogen ions known as?

• Lactate Tolerance Level

• Lactate Resistance Point

• Lactate Endurance Limit

• Lactate Inflection Point

Answer explanation

The highest intensity of aerobic exercise an athlete can sustain without the rapid accumulation of hydrogen ions is known as the Lactate Inflection Point.

What is the point beyond which lactate production exceeds removal and begins to accumulate in the blood?

• Lactate Inflection Point

• Lactate Saturation Point

• Lactate Accumulation Point

• Lactate Overflow Point

Answer explanation

The point beyond which lactate production exceeds removal and begins to accumulate in the blood is called the Lactate Inflection Point. This is the correct choice.

What is the final exercise intensity beyond which a given exercise or power output cannot be maintained for any sustained period of time?

• Lactate Burnout Threshold

• Lactate Inflection Point

• Lactate Fatigue Limit

• Lactate Exhaustion Point

Answer explanation

The final exercise intensity beyond which a given exercise or power output cannot be maintained for any sustained period of time is called the Lactate Inflection Point.

What is the process by which lactate is converted back to glucose and glycogen in the liver?

• Lactate Regeneration Pathway

• Lactate Conversion Cycle

• Cori-Cycle

• Lactate Transformation Process

Answer explanation

The process by which lactate is converted back to glucose and glycogen in the liver is called the Cori-Cycle. It is an important metabolic pathway.

What is the point where lactate production and removal is balanced known as?

• Lactate Inflection Point

• Lactate Balance Point

• Lactate Stability Point

• Lactate Equilibrium Point

Answer explanation

The point where lactate production and removal is balanced is known as the Lactate Inflection Point.

What is the highest intensity point where there is a balance between lactate production and removal from the blood?

• Lactate Equilibrium Point

• Lactate Balance Point

• Lactate Inflection Point

• Lactate Stability Point

Answer explanation

The highest intensity point where lactate production and removal from the blood are balanced is called the Lactate Inflection Point. At this point, lactate levels stabilize, indicating a balance between production and removal.
