Question 1

A collegiate basketball player's resting metabolic rate is estimated at 1,900 kcal/day. Using an activity factor of 1.7 for heavy training, what is the estimated total daily energy expenditure?

Accepted Answer

3,230 kcal

Answer

Multiplying RMR (1,900 kcal) by the activity factor (1.7) gives an estimated TDEE of 3,230 kcal/day.

Question 2

An athlete presents with low energy availability (LEA). Which combination of findings is most consistent with the Female Athlete Triad?

Accepted Answer

Low EA, low bone mineral density, menstrual dysfunction

Answer

The Female Athlete Triad is defined by the interrelated conditions of low energy availability, menstrual dysfunction, and low bone mineral density.

Question 3

Which pre-exercise meal timing recommendation minimizes GI distress while still providing meaningful glycogen loading?

Accepted Answer

1-4 hours before with a moderate-carbohydrate, low-fat, low-fiber meal

Answer

Consuming a moderate-carbohydrate meal low in fat and fiber 1-4 hours before exercise provides fuel without causing significant GI distress during performance.

Question 4

What is the primary goal of carbohydrate loading for an endurance event lasting more than 90 minutes?

Accepted Answer

Maximize liver and muscle glycogen stores above normal resting levels

Answer

Carbohydrate loading (supercompensation) aims to maximize pre-exercise glycogen stores in both the liver and skeletal muscle to delay fatigue during prolonged events.

Question 5

Beta-alanine supplementation improves performance primarily by increasing intramuscular concentrations of which buffer?

Accepted Answer

Carnosine

Answer

Beta-alanine is the rate-limiting precursor to carnosine synthesis; increased carnosine acts as an intramuscular pH buffer, delaying fatigue during high-intensity exercise.
