What does the term 'nutrient timing' refer to in CrossFit nutrition?
Answer: Strategically consuming specific nutrients at specific times relative to exercise
Nutrient timing refers to the strategic consumption of macronutrients at specific times—particularly around training—to optimize performance and recovery.
A CrossFit trainer is working with a client who wants to lose body fat without sacrificing strength. Which caloric approach is most appropriate?
Answer: A modest deficit of 200-500 kcal/day while maintaining adequate protein
A modest deficit of 200-500 kcal/day with adequate protein preserves lean mass while promoting sustainable fat loss.
Which micronutrient deficiency is most commonly linked to impaired muscle contraction and cramping in high-sweat-rate athletes?
Answer: Magnesium
Magnesium is critical for muscle contraction and relaxation; deficiency—common in heavily sweating athletes—often manifests as cramping.
In CrossFit's nutrition framework, what distinguishes 'performance nutrition' from the base prescription?
Answer: Performance nutrition involves precise quantity measurement and optimization around training demands
Performance nutrition adds precise measurement and strategic timing on top of the foundational whole-food prescription to optimize competitive and high-demand training outcomes.
Which carbohydrate source would be MOST appropriate immediately post-WOD for rapid glycogen replenishment?
Answer: White rice or banana
High-glycemic, easily digestible carbohydrates like white rice or banana are ideal immediately post-workout for rapid glycogen replenishment.
How does protein intake support immune function in athletes undergoing high training volumes?
Answer: Amino acids serve as precursors for antibodies and immune cell production
Amino acids derived from dietary protein are essential precursors for synthesizing antibodies and immune cells, making adequate protein critical for immune health in hard-training athletes.
An endurance-focused CrossFit athlete is training 2x daily. Which nutritional adjustment is most critical compared to a 1x/day athlete?
Answer: Increasing total caloric and carbohydrate intake to support glycogen recovery between sessions
Two-a-day training requires significantly increased total calories and carbohydrates to replenish glycogen between sessions and fuel both workouts adequately.
