CCSP Sports Nutrition Principles 2

Question 1

An athlete reports consuming a high-protein diet (3g/kg/day). What is the primary risk associated with chronic excessive protein intake in a healthy athlete?

Accepted Answer

Potential renal stress and increased calcium excretion

Answer

Chronically excessive protein intake can strain renal function and promote calciuria, increasing fracture risk over time.

Question 2

Which amino acid is conditionally essential during periods of high-intensity training or physiological stress?

Accepted Answer

Glutamine

Answer

Glutamine becomes conditionally essential during intense exercise stress as demand exceeds the body's synthetic capacity.

Question 3

A cyclist competing in a 5-hour road race should primarily rely on which energy substrate during the final hour when intensity increases?

Accepted Answer

Muscle glycogen and exogenous carbohydrate

Answer

At higher intensities, muscle glycogen and ingested carbohydrate become the dominant fuels because fat oxidation cannot sustain the required ATP production rate.

Question 4

The thermic effect of food (TEF) is highest for which macronutrient?

Accepted Answer

Protein

Answer

Protein has the highest TEF (~20–30%), meaning the body expends more energy digesting and metabolizing it compared to carbohydrate (~5–10%) or fat (~0–3%).

Question 5

Which index best describes the rate and magnitude of blood glucose rise after consuming a specific food compared to pure glucose?

Accepted Answer

Glycemic index

Answer

The glycemic index (GI) ranks foods on a 0–100 scale based on their postprandial blood glucose response relative to pure glucose.
