Which of the following is classified as an essential amino acid that must be obtained from the diet?
Answer: Leucine
Leucine is one of nine essential amino acids and is a key stimulator of muscle protein synthesis via the mTOR pathway.
A client following a ketogenic diet primarily relies on which substrate for brain and muscle energy after glycogen depletion?
Answer: Ketone bodies
During ketosis, the liver converts fatty acids into ketone bodies (beta-hydroxybutyrate, acetoacetate) that serve as an alternative fuel for the brain and muscles.
What is the recommended daily intake of sodium for the general adult population according to the Dietary Guidelines for Americans?
Answer: Less than 2,300 mg/day
The Dietary Guidelines for Americans recommend limiting sodium to less than 2,300 mg per day for most adults.
Which micronutrient deficiency is most commonly associated with exercise-induced anemia in endurance athletes?
Answer: Iron
Iron is required for hemoglobin synthesis; endurance athletes lose iron through sweat, GI microbleeding, and hemolysis, making deficiency common.
Which type of carbohydrate has the highest glycemic index and would be most appropriate for immediate post-exercise glycogen replenishment?
Answer: Pure glucose/dextrose
Pure glucose has a glycemic index of 100 and is rapidly absorbed, making it ideal for quickly restoring muscle glycogen after intense exercise.
During prolonged aerobic exercise lasting more than 90 minutes, which nutritional strategy is most effective at maintaining performance?
Answer: 30–60 g of carbohydrate per hour
Current guidelines recommend 30–60 g of carbohydrate per hour during prolonged exercise to spare muscle glycogen and sustain blood glucose.
Which vitamin acts as an antioxidant and is involved in collagen synthesis, making it relevant for connective tissue repair after exercise?
Answer: Vitamin C
Vitamin C (ascorbic acid) is a cofactor for prolyl hydroxylase in collagen synthesis and also neutralizes reactive oxygen species.
