Question 1

Which macronutrient is the primary fuel source during high-intensity anaerobic exercise?

Accepted Answer

Carbohydrate

Answer

Carbohydrates (stored as glycogen) are the dominant fuel for high-intensity anaerobic efforts because they can be metabolized rapidly without oxygen.

Question 2

An athlete training twice per day would most benefit from consuming a recovery meal containing which ratio of carbohydrates to protein?

Accepted Answer

3:1 to 4:1

Answer

A 3:1 to 4:1 carbohydrate-to-protein ratio after exercise optimally replenishes glycogen while supporting muscle repair.

Question 3

What is the IIN-aligned term for foods that provide both nutrients and bioactive compounds supporting athletic recovery?

Accepted Answer

Functional foods

Answer

Functional foods are whole or minimally processed foods that offer health benefits beyond basic nutrition, a concept emphasized in IIN's integrative approach.

Question 4

Sodium loss through sweat is most critical to replace during exercise lasting longer than:

Accepted Answer

90 minutes

Answer

Sodium replacement becomes important after about 90 minutes of sustained exercise when cumulative sweat losses begin to affect performance and electrolyte balance.

Question 5

Which amino acid is considered conditionally essential during periods of intense physical training due to increased demand?

Accepted Answer

Glutamine

Answer

Glutamine is conditionally essential during heavy training because muscle glutamine stores can drop significantly, impairing immune function and recovery.
