CCSP Sports Nutrition Principles 3

Question 1

Which electrolyte is lost in the greatest quantity through sweat and must be prioritized in fluid replacement strategies?

Accepted Answer

Sodium

Answer

Sodium is the primary electrolyte in sweat (~20–80 mmol/L) and its replacement is critical for maintaining plasma osmolality and preventing hyponatremia.

Question 2

Relative Energy Deficiency in Sport (RED-S) primarily results from:

Accepted Answer

Low energy availability due to insufficient caloric intake relative to exercise energy expenditure

Answer

RED-S occurs when dietary energy intake is insufficient relative to exercise energy expenditure, impairing hormonal, bone, and metabolic function.

Question 3

An athlete consuming a pre-exercise meal high in fat and protein but low in carbohydrate is MOST likely to experience:

Accepted Answer

Delayed gastric emptying and potential GI discomfort

Answer

High fat and protein content slows gastric emptying, potentially causing GI distress and delivering less usable fuel during exercise.

Question 4

Beta-alanine supplementation improves performance primarily by:

Accepted Answer

Elevating muscle carnosine content to buffer hydrogen ions

Answer

Beta-alanine is the rate-limiting precursor for carnosine synthesis; higher muscle carnosine buffers H⁺ ions that accumulate during high-intensity exercise.

Question 5

Which vitamin functions as an antioxidant and is critical for collagen synthesis, making it particularly relevant for connective tissue recovery in athletes?

Accepted Answer

Vitamin C

Answer

Vitamin C (ascorbic acid) is essential for hydroxylation of proline and lysine in collagen synthesis and also acts as a water-soluble antioxidant.
