Question 1

"Carbohydrate loading" is a pre-competition nutritional strategy primarily used to:

Accepted Answer

Maximize muscle and liver glycogen stores prior to a prolonged event

Answer

Carbohydrate loading maximizes glycogen storage in muscle and liver before prolonged endurance events, thereby delaying glycogen depletion and fatigue.

Question 2

Which macronutrient has the highest thermic effect of feeding (TEF), meaning the body expends the most energy to digest and metabolize it?

Accepted Answer

Protein

Answer

Protein has a thermic effect of approximately 20–30% of its caloric content, compared to 5–10% for carbohydrates and 0–3% for fat, making it the most metabolically costly macronutrient to process.

Question 3

Relative Energy Deficiency in Sport (RED-S) is characterized by:

Accepted Answer

Low energy availability negatively affecting health and performance across multiple body systems

Answer

RED-S describes the widespread health and performance consequences of chronic low energy availability, including hormonal disruption, reduced bone density, impaired immunity, and psychological effects, in both male and female athletes.

Question 4

Sodium replacement during prolonged exercise lasting more than 2 hours is important primarily to prevent:

Accepted Answer

Hyponatremia (dangerously low blood sodium)

Answer

Hyponatremia can develop when athletes consume large volumes of plain water without replacing sodium losses through sweat, dangerously diluting blood sodium concentration.

Question 5

The glycemic index (GI) of a food is BEST defined as:

Accepted Answer

How quickly a food raises blood glucose concentration relative to a reference food

Answer

The glycemic index ranks carbohydrate-containing foods by how rapidly they raise blood glucose compared to a reference food (pure glucose = 100), helping athletes select appropriate pre- and post-exercise fuel sources.
