A basketball player experiences nausea and dizziness during a summer practice. His urine is dark yellow. The FIRST nutritional intervention is:
Answer: Have him drink water or a sports drink immediately
Dark urine and symptoms indicate dehydration; immediate fluid replacement with water or a sports drink is the priority intervention.
Which macronutrient ratio is MOST appropriate for an endurance athlete's training diet?
Answer: 60–70% carbohydrate, 15–20% protein, 15–25% fat
Endurance athletes require high carbohydrate intake (60–70%) to fuel prolonged aerobic activity, with moderate protein and fat.
Beta-alanine supplementation improves performance primarily by:
Answer: Buffering intramuscular hydrogen ions (H+) via carnosine synthesis
Beta-alanine is a carnosine precursor; carnosine buffers intramuscular acidosis (H+ accumulation) during high-intensity exercise.
An athletic trainer should refer an athlete to a Registered Dietitian (RD) when:
Answer: Signs of disordered eating or a clinical nutrition disorder are identified
Disordered eating and clinical nutrition disorders require the expertise of a Registered Dietitian for assessment and treatment.
Which dietary pattern is MOST associated with reduced cardiovascular disease risk and is often recommended for overall athlete health?
Answer: Mediterranean diet
The Mediterranean diet, rich in vegetables, whole grains, healthy fats, and lean proteins, has the strongest evidence for cardiovascular health benefits.
Glycemic index (GI) refers to:
Answer: How rapidly a food raises blood glucose relative to a reference food
Glycemic index ranks foods based on how quickly they raise blood glucose levels compared to a reference food (glucose or white bread).
Which post-exercise recovery ratio of carbohydrate to protein has been shown to optimally promote glycogen resynthesis and muscle repair?
Answer: 3:1 (carbohydrate:protein)
A 3:1 carbohydrate-to-protein ratio post-exercise has been shown to optimize both glycogen resynthesis and muscle protein synthesis.
