Crossfit Nutrition & Performance Optimization 3

Question 1

When should an athlete consume carbohydrates for optimal glycogen resynthesis after a CrossFit WOD?

Accepted Answer

Within 30–60 minutes post-workout

Answer

The 30–60 minute post-exercise window offers the highest rate of glycogen resynthesis due to elevated GLUT4 transporter activity.

Question 2

Which fat type should CrossFit athletes prioritize to support anti-inflammatory recovery?

Accepted Answer

Omega-3 polyunsaturated fats

Answer

Omega-3 fatty acids (found in fatty fish, flaxseed, walnuts) have anti-inflammatory properties that support recovery from intense training.

Question 3

A 150 lb CrossFit athlete training twice per day wants to estimate daily caloric needs. Which factor is MOST important to apply to a base metabolic rate calculation?

Accepted Answer

An activity multiplier reflecting training volume and intensity

Answer

Total daily energy expenditure is calculated by multiplying BMR by an activity factor that accounts for training frequency and intensity.

Question 4

What is the primary role of magnesium in athletic performance relevant to CrossFit?

Accepted Answer

Muscle contraction, protein synthesis, and energy metabolism

Answer

Magnesium supports muscle contraction, protein synthesis, and ATP-based energy production, all critical to CrossFit performance.

Question 5

A CrossFit trainer notices an athlete is consuming very high protein (3+ g/lb/day) while restricting carbohydrates severely. What is the most likely performance consequence?

Accepted Answer

Gluconeogenesis from protein may partially compensate, but glycolytic performance will still suffer

Answer

Although gluconeogenesis can produce some glucose from amino acids, it cannot supply glycolytic fuel fast enough to sustain high-intensity CrossFit output.
