Question 1

A client doing two aerobics classes per day asks about post-workout nutrition timing. What is the ideal window to consume protein and carbohydrates after exercise?

Accepted Answer

Within 30–45 minutes

Answer

Consuming protein and carbohydrates within 30–45 minutes post-exercise maximizes muscle glycogen resynthesis and muscle protein synthesis.

Question 2

Which macronutrient is the PRIMARY fuel source during high-intensity aerobic exercise?

Accepted Answer

Carbohydrates

Answer

Carbohydrates (as muscle glycogen and blood glucose) are the primary fuel during high-intensity aerobic activity.

Question 3

A female aerobics instructor reports fatigue, poor concentration, and cold intolerance. Which nutritional deficiency should a CAT trainer suspect first?

Accepted Answer

Iron

Answer

Iron-deficiency anemia is common in active females and presents with fatigue, brain fog, and cold sensitivity due to impaired oxygen transport.

Question 4

When advising a client on hydration, how much water should be consumed approximately 2 hours before an aerobics class?

Accepted Answer

17–20 oz

Answer

ACSM recommends consuming 17–20 oz (500–600 mL) of water about 2 hours before exercise to ensure euhydration.

Question 5

A client following a very low-carbohydrate diet (<50g/day) reports decreased performance in step aerobics class. What is the most likely cause?

Accepted Answer

Depleted muscle glycogen stores

Answer

Very low carbohydrate intake depletes muscle glycogen, the primary fuel for high-intensity aerobic exercise, reducing performance.
