Question 1

A competitive cyclist asks about beetroot juice supplementation. Its ergogenic effect is primarily attributed to:

Accepted Answer

Nitrate content enhancing mitochondrial efficiency and blood flow

Answer

Beetroot juice is high in dietary nitrate, which is converted to nitric oxide in the body, improving muscle oxygen efficiency and exercise capacity.

Question 2

The Recommended Dietary Allowance (RDA) for protein in highly trained strength athletes is closest to:

Accepted Answer

1.6-2.2 g/kg/day

Answer

Current evidence supports 1.6-2.2 g/kg/day for maximizing muscle protein synthesis in resistance-trained athletes, well above the general population RDA of 0.8 g/kg/day.

Question 3

Which micronutrient deficiency is MOST commonly associated with reduced aerobic capacity due to impaired oxygen transport?

Accepted Answer

Iron

Answer

Iron deficiency impairs hemoglobin synthesis, directly reducing oxygen-carrying capacity and VO2max in endurance athletes.

Question 4

HMB (beta-hydroxy-beta-methylbutyrate) supplementation is purported to enhance performance primarily by:

Accepted Answer

Reducing muscle protein breakdown (anti-catabolic effect)

Answer

HMB is a leucine metabolite that inhibits ubiquitin-proteasome proteolysis, reducing muscle protein catabolism, particularly during initial training or caloric restriction.

Question 5

Which of the following electrolytes is MOST critical for preventing exercise-associated muscle cramps according to current evidence?

Accepted Answer

Sodium

Answer

Sodium is the primary electrolyte lost in sweat, and sodium deficiency during prolonged exercise is the most well-supported cause of exercise-associated muscle cramps.
