Bodybuilding Bodybuilding Supplementation 2 — Questions and Answers
Question 1: What does HMB stand for in bodybuilding supplementation?
- Hypertrophy Muscle Builder
- Beta-Hydroxy Beta-Methylbutyrate (Correct answer)
- High-Metabolic Buffer
- Hormone Metabolite Booster
Correct answer: Beta-Hydroxy Beta-Methylbutyrate
HMB (Beta-Hydroxy Beta-Methylbutyrate) is a metabolite of leucine that may reduce muscle protein breakdown.
Question 2: Which form of protein is derived from milk and digests slowly, making it ideal before bed?
- Whey isolate
- Casein protein (Correct answer)
- Egg white protein
- Pea protein
Correct answer: Casein protein
Casein forms a gel in the stomach, releasing amino acids slowly over several hours, making it perfect for overnight muscle repair.
Question 3: What is the main ergogenic mechanism of citrulline malate in pre-workout supplements?
- It increases testosterone levels
- It increases nitric oxide production for improved blood flow (Correct answer)
- It directly builds muscle glycogen
- It blocks cortisol receptors
Correct answer: It increases nitric oxide production for improved blood flow
Citrulline malate boosts nitric oxide synthesis, widening blood vessels and delivering more oxygen and nutrients to muscles.
Question 4: Fish oil supplementation in bodybuilding is primarily valued for which benefit?
- Increasing muscle glycogen
- Reducing inflammation and supporting joint health (Correct answer)
- Boosting testosterone beyond normal levels
- Providing quick energy during workouts
Correct answer: Reducing inflammation and supporting joint health
Fish oil's omega-3 fatty acids (EPA and DHA) help reduce exercise-induced inflammation and support joint integrity.
Question 5: What is the role of zinc in a bodybuilder's supplementation stack?
- It directly stimulates muscle hypertrophy
- It supports testosterone production and immune function (Correct answer)
- It increases glycogen storage capacity
- It blocks estrogen receptors
Correct answer: It supports testosterone production and immune function
Zinc is a cofactor in testosterone synthesis and immune function, both critical for recovery and muscle building.
Question 6: What is the primary difference between whey protein concentrate and whey protein isolate?
- Isolate contains more carbohydrates
- Isolate has a higher protein percentage and less fat and lactose (Correct answer)
- Concentrate is faster digesting
- Isolate contains more calories per serving
Correct answer: Isolate has a higher protein percentage and less fat and lactose
Whey isolate undergoes further filtration to remove more fat and lactose, yielding 90%+ protein content versus 70–80% in concentrate.
