What is the primary function of insulin in the context of post-workout nutrition?
Answer: To shuttle glucose and amino acids into muscle cells for glycogen resynthesis and repair
Post-workout insulin shuttles glucose into muscles for glycogen resynthesis and drives amino acids into muscle cells to support repair and growth.
A client following a strict Paleo diet asks about pre-workout carbohydrate options. Which of the following is Paleo-compliant AND effective for pre-workout energy?
Answer: Sweet potato with coconut oil
Sweet potato with coconut oil is Paleo-compliant, providing moderate-glycemic carbohydrates and healthy fat for sustained pre-workout energy.
Which statement about creatine supplementation is most accurate for CrossFit athletes?
Answer: Creatine monohydrate is well-researched and can support high-intensity, short-duration efforts like those in CrossFit
Creatine monohydrate is one of the most well-researched supplements and has demonstrated benefits for high-intensity, short-duration efforts common in CrossFit workouts.
How should a CrossFit trainer respond when a client asks about a specific commercial diet plan not covered in CrossFit's curriculum?
Answer: Evaluate it against CrossFit's foundational nutrition principles and refer to a registered dietitian for detailed guidance
Trainers should evaluate outside diets against core CrossFit principles and refer clients to a registered dietitian for personalized, detailed nutritional counseling.
What effect does chronic under-eating have on resting metabolic rate (RMR) over time?
Answer: RMR decreases as the body adapts to conserve energy in a prolonged caloric deficit
Chronic under-eating causes the body to downregulate metabolic rate as an adaptive response to conserve energy, making sustained fat loss increasingly difficult.
Which of the following best explains why vegetable intake is emphasized in CrossFit's nutrition prescription?
Answer: Vegetables supply essential micronutrients, fiber, and phytonutrients that support overall health and performance
Vegetables provide a wide spectrum of essential vitamins, minerals, fiber, and phytonutrients that support immune function, recovery, and overall health.
An athlete's performance has plateaued despite consistent training. A nutrition audit reveals very low fat intake (~15% of calories). What is the most likely nutritional consequence?
Answer: Impaired hormone production, particularly testosterone and cortisol regulation
Very low fat intake impairs production of steroid hormones including testosterone, which is critical for muscle adaptation, strength, and performance.
