Nutrient timing research suggests that consuming a meal containing protein and carbohydrate BEFORE resistance training primarily serves to:
Answer: Elevate circulating amino acids and insulin to support anabolic conditions during exercise
A pre-exercise meal raises plasma amino acid and insulin levels, creating an anabolic environment that can attenuate muscle protein breakdown and support muscle protein synthesis during the training bout.
An athlete who is a vegan must pay particular attention to which nutrient most likely to be deficient in a purely plant-based diet?
Answer: Vitamin B12
Vitamin B12 is found almost exclusively in animal products; vegan athletes are at high risk for deficiency and typically require supplementation or B12-fortified foods.
Which ergogenic aid has the strongest evidence base (Grade A) for improving both strength and power output, making it one of the most researched sports supplements?
Answer: Creatine monohydrate
Creatine monohydrate is consistently rated Grade A by the ISSN due to decades of research demonstrating significant, reproducible improvements in strength, power, and lean mass.
Hyponatremia in endurance athletes is primarily caused by:
Answer: Excessive hypotonic fluid intake diluting blood sodium below normal levels
Exercise-associated hyponatremia most often results from drinking too much plain water (or low-sodium fluids) relative to sweat sodium losses, diluting serum sodium to dangerous levels.
Which dietary fat source is particularly emphasized for athletes to support anti-inflammatory responses, joint health, and cardiovascular function?
Answer: Omega-3 fatty acids (EPA and DHA) from fatty fish or algae
EPA and DHA omega-3 fatty acids have strong anti-inflammatory and cardioprotective effects and are particularly valuable for athletes experiencing high training-induced inflammation.
A certified nutrition coach should refer an athlete to a Registered Dietitian (RD) or sports medicine physician when the athlete presents with:
Answer: Signs of disordered eating, RED-S, or a diagnosed medical condition requiring medical nutrition therapy
Disordered eating, clinical energy deficiency syndromes like RED-S, and medical diagnoses require evaluation and intervention by licensed healthcare professionals beyond the scope of a nutrition coach.
